Tropical depression 01w
Pressure:1004hpa
FIRST CYCLONE OF THE YEAR 2011!!!
History:On April 1st, the first tropical depression of the year formed near Spratly Island, about 540 km (335 mi) to the east-southeast of Ho Chi Minh City,Vietnam. Strong winds were pushing all cloud productions
to the west of the tropical depression,leaving only an exposed
center. Vietnam experienced heavy rain because all clouds are pushed to the left side, making it a concentrated spot of clouds.soon the storm head west and faded away.
Tropical depression02w, (Amang)
On March 30, an area of low pressure associated with frontal system formed about 220 km (135 mi) in the southwest of Yap islands.In the couple of next days the low pressure headed west towards Philippine.on March 31-April 3,The system began to organize while hanging around the south east of Philippine..Upper wind shear were ideal and on April 3 The
TSW (Typhoon storm watch), JMA upgraded the low pressure as Tropical depression 03w,Amang.Soon it was heading North east.The wind shear that was helping the development began to weaken and soon the system was exposed to the northern winds and faded away.
Information:Highest wind speed: 58 km/h (36 mph)

Highest Winds speeds:117kilometers per hour
Central Pressure:969Hpa
Storm size:Large
Duration:June 20-June 29
History:On June 15, a area of disturbed weather developed
On June 17,and then the system organized,and on June 20 the tropical disturbance strengthened,and was Located about
758km(758 km (470 mi), east of the Philippines.As It moved closer and closer to the Philippines the Typhoon Storm Watch and the JMA ,JTWC started to monitor it.It was soon upgraded into a tropical depression by the PAGASA, naming it Falcon. At the time of the upgrade, Falcon was located about 1000 km (620 miles), east northeast of Cebu City.Then during the evening of June 22,The Joint Typhoon Warning center and the Typhoon storm watch Ungraded the system into a Tropical storm.The system seem to b growing bigger in size and seem to be made of mostly thunderclouds instead of normal cumulus clouds.The system was upgraded into a Severe Tropical storm in the afternoon of June 24, with sustained winds of 91 kilometers per hour,by the Typhoon Storm Watch and Japan meteorological Agency.Soon the system had sustained wind speeds of 101km/h and was heading towards Okinawa, Japan. After making Landfall in Okinawa, Japan, the system started to intensified with sustained winds of 118km/h.But on the evening of June 24, the system was downgraded into a Tropical storm as it heads towards north Korea.On the evening of June 26, the system was further downgraded into at tropical depresion as it makes landfall in North Korea.Meari caused $1.24MillionUSD worth of Damage and killed 2 people in the Philippines,totally killing 11 people.

The 11th Cyclone of The 2011 Pacific Typhoon season
History:On June 30, a Tropical wave developed about 250 kilometers north of Wake island.The system slowly moved west, than suddenly moved south into the warmer waters on July 7-8.Due to the warm waters fueling the small wave, It slowly began to rotate, and was certified as a Tropical disturbance on July 9.And On July 11, the Japan Meteorological Agency, upgraded the Tropical disturbance as a Tropical depression.On July 12,the JMA and JTWC upgraded the system to a tropical storm and named it Ma-on.Early On July 13, the Typhoon Storm Watch and the Japan Meteorological Agency upgraded Ma-On into a
Severe Tropical storm.
Severe Tropical storm Ma-On also seems to be developing a eye, but the eye of Severe Tropical Storm Ma-on soon dissipated 3 hours later...but 4 Hours later, Severe tropical Storm Ma-On developed a Eye again,but again, dissipated.In the Midnight of July 13, Severe Tropical Storm Ma-On Intensified into a Category 1 Typhoon and a few hours later it intensified even more into a category 2 early on July 14.And in the morning of July 15, Ma On intensified into a category 3 Typhoon ,with sustained winds of 191 kilometers per hour winds.It also developed a smaller eye which didn't dissipated, and could be the Typhoon Ma -on's First real eye,and In the evening of July 15, Ma-On Intensified into a category 4 .But the eye soon dissipated again 3 Hours later.On July 16, another eye formed as Typhoon Ma-On absorb Tropical Storm Tokage, which is rare for a cyclone to absorb another one at it's strongest intensity.
Typhoon ma-On and Tropical Storm Tokage
later that Day, Ma-On developed another eye which soon became a Small eye.As Ma-On Moved North west it weakened into a category 3 Typhoon and was having a eye wall Replacement cycle.Early on July 18, category 3 Typhoon Ma-On Weakened into a category 2 Typhoon, than continue to weakened into a category 1 Typhoon as it made landfall in Shimanto, Japan.It further weakened into a Severe Tropical Storm on July 20 as it head South east, and Further weakened into a Tropical depression on July 21.Due to its southeast path towards warmer waters, it intensified again into a Severe Tropical Storm.It further weakened into a tropical storm as it head north,while developing an exposed center.On July 24, Ma-on weakened into an extratropical cyclone east of the Tōhoku region, and dissipated.
Ma On caused $27.8 Million USD worth of damge and killed 5 lives, as it moved though the Northern Mariana Islands and Japan.

Typhoon Nock-Ten as a tropical depression with a exposed center.
On July 16 Tropical depression Juaning was upgraded into a Tropical storm,and was named Nock-Ten by the Japan Meteorological Agency.By July 28, 35 People were killed in the Philippines, and 25 crewmembers of a fishing boat were reported missing when their fishing boat was caught in the storm off Masbate,as Tropical Storm Nock-ten intensified into a category 1 Typhoon,as well as developing a eye,however it soon weakened into a Severe tropical Storm,as it made landfall over northern Aurora (province).
The provinces of Albay and Camarines were reported to be completely flooded by the rain.
Early on July 28, Severe Tropical Storm Nock-ten entered the South china sea and was centered about 500 kilometres south-southeast of Hong Kong,and the Hong Kong Observatory Hosted the Typhoon Wind Signal No.1 and later in the evening,the Typhoon Wind Signal No.3 was hosted as Severe Tropical storm Nock-ten was centred about 450 km South of Hong Kong.
Typhoon Nock-Ten at its closest to Hong Kong
Later the Typhoon Signal No.3 was replaced by the Typhoon Wind signal No.1 as Severe Tropical Storm Nock-ten moves farther away from Hong Kong,while making landfall in Hainan island,China on the afternoon of July 29.Early on July 30, Nock-Ten drifted though Hainan island and entered the Gulf of Token and soon made landfall at Quỳnh Phụ, Thai Binh, Vietnam,and weakened into a Tropical depression on July 31,and in dissipated into a area of Low pressure in the afternoon of July 31.
Typhoon Nock-Ten killed 56 people in the Philippines,and caused a damage of $99 million USD

Eye type and size:Small,Large double eye walls
Type of Storm:Normal(when it was a Tropical Storm, it was a Exposed center cyclone)
Storm Category:Category 5 super Typhoom
History:Early on July 22 an broad area of clouds show that a Tropical wave has developed, and the area stretch from eastern Philippines to Micronesia.On July 24, a small area of The Wave started to rotate and The TSW certified the the low as a Tropical Disturbance as it moved north west.Late July
25 the Disturbance was Upgraded into a Tropical depression by the Japan and meteorological agency.On July 28, the Typhoon Storm Watch(TSW) and the JTWC upgraded Tropical depression 11w as a tropical Storm, however it still remained unnamed.On July 28, Tropical Storm 11w was finally named as Muifa,and the PAGASA named it Kabayan.On the night of July 29,Tropical storm Muifa was upgraded into a Severe Tropical storm and Overnight it quickly upgraded into a Typhoon and quickly strengthen into a Category 5 Typhoon on July 30.According to the JTWC, On July 31, the typhoon interacted with an upper level trough and weakened into a Category 4 Typhoon on the SSHS,at the same time, Muifa's eye dissipated.
Muifa killed 2 men, as their boat was capsized in the vicinity of Hagonoy, Bulacan and Pampanga Delta.Typhoon Muifa continued to weakened into a Category 3 Typhoon,as it head north west.It later strengthend slightly as it develops a new eye, but due to weak high wind shears, Muifa instead develops double eye walls,and weakens further into a Category 2 typhoon,and later develops a disorganize large eye,and soon it was a category 1 Typhoon.As Muifa headed north, it weakened into a Severe Tropical Storm on August 7.It soon Made Landfall at Dandong, Liaoning, China on August 8 2011,as well as weakening into a Extropical Storm.Early on August 9, Muifa weakened to a ex tropical depression in Northeast China and became a low pressure area later.Muifa caused $480USD million worth of Damge and killed 22 people.

Storm Track:
History:On August 16, a Tropical Wave formed near Guam and Moved west.It slowly Organized and the Typhoon Storm Watch certified the Wave as a Tropical Disturbance.On August 21 the Typhoon Storm Watch and the JMA upgraded the disturbance as a Tropical Depression. On August 21, the PAGASA named the system Mina.And on August 23 the Storm Intensified into a Tropical storm,As it moved North and late on August 23, the JMA upgraded 14W to a tropical Overnight, the system continued to intensify and early on August 24, the Typhoon Storm Watch and the JMA upgraded Nanmadol to a severe tropical storm.Early on August 25 convective banding improved and Nanmadol developed an eye-like feature as it intensified into a category one Typhoon.On August 26, the system intensified rapidly and become a Category 5 Super Typhoon on the morning of August 26.The typhoon developed a classic sized eye with a diameter of 18 nautical miles (33 km; 21 mi) with highly symmetric deep convective bands wrapped into it.
The Eye Typhoon Nanmadol
It was forecast to continue intensifying, however because of the Fujiwhara effect, between Nanmadol and Talas, Namadol instead head west instead of north,and made landfall at Gonzaga, Cagayan, Philippines, and weakened into a Category 3 Typhoon.
At the same time, the eye of Nanamdol after interacting with land, the eye of Nanmado lcloud filled and the eyewall in the northern semicircle became eroded causing the system to weaken. The typhoon maintained a favorable upper level outflow, though located in a mid-level subtropical ridge. As Nanmadol started moving away from Luzon, the eye became more evident and central convection became re-consolidated with curved banding. However, the typhoon did not maintain this for long. Nanmadol could not recover very well from interacting with land and started weakening as the cloud tops were warming up and the eye was being filled with clouds again.During the early hours of August 28, Nanmadol struggled to strengthen after passing over the Babuyan Islands.
The eye became completely cloud-filled and the outermost rainbands crossed over Taiwan.Meanwhile, Tropical Storm Talas was feeding on Nanmadol's clouds and Nanmadol was feeding off Talas clouds-The two cyclones are both sucking clouds out of each other.Typhoon Nanmadol soon further weakened into a Category 1 Typhoon despite moving towards to the warm sea of Taiwan,and soon made and on August 28, Nanmadol made landfall over Dawu, Taitung, Taiwan before the JTWC downgraded it to a tropical storm.Nanmadol made its third and Final landfall with land on August 31 at Quanzhou, Fujian, China weakened into a Tropical Depression.The Remnants soon drifted to mainland China and dissipated completely on September 3.
On August 27, five people died after Nanmadol caused landslides.At least two Filipino fishermen were reported to be missing after Nanmadol's strong winds whipped up large waves.

Highest Maximum Sustained winds:123km/h
Lowest Pressure:965hpa
Deaths:53
Damage:Unknown
Deaths:53
Damage:Unknown
History:On August 19, a Tropical Wave developed in the WNPacfic and slowly moved South west and was Upgraded into a Tropical Disturbance by the Typhoon Storm Watch on August 22.On August 23 the system developed a ciculation center and was upgraded into a Tropical Depression by the Typhoon Storm Watch and the JMA.On August 23, the system moved into an environment of low wind shear and warm sea surface temperatures prompting the JTWC to issued a TCFA on it.By August 25, the Typhoon Storm Watch and the JMA had declared it a tropical storm, and named it Talas.It soon strengthen into a Severe Tropical storm early on August 26.On August 27, the system appeared to have developed a Large eye,at 280 kilometers across,But soon dissipated on August 28.Multiple competitive steering ridges caused Talas to move in a poleward direction with stronger winds in the periphery and weaker winds near the center. A tropical upper tropospheric trough (TUTT) caused subsidance in the atmosphere which caused a disturbance in the outflow towards the northwest of the system. However, another TUTT cell to the northeast opened an outflow channel which kept Talas from being destroyed by shear.Talas was very loosely organized with a relatively open circulation center and very low consolidation around the core. Convection was also displaced towards the periphery and stronger wind shear kept Talas from strengthening.
Talas, being located in a very weak steering environment hardly moved in 24 hours(The storm still moved slowly ranging from 1.6km/h to 4km/h) and was effectively trapped between strong subtropical ridges and an anticyclone. Talas failed to strengthen for a very long time and remained loosely organized with all the convection located in the periphery. Early on August 28, Talas started to strengthen after a whole day in dry winds. The low-level circulation center started to get consolidated with deep convective bands wrapping into it.
Talas was expected to make landfall over central japan with strong winds. Talas then moved into an environment favorable for slow development, with moist winds and significantly warm sea surface temperatures. The center became well organized with convective bands tightly wrapped into it.Wind shear decreased and the center was wrapped with more tightly curved banding.
Late on August 29, the TSW and the JMA upgraded Talas to a typhoon.While it developed a new Large eye again on September 1st.But soon the system weakened on September 2 into a severe Tropical storm due to interaction with land.Early on September 3, Talas made landfall over Aki, Japan.After landfall, Talas accelerated north at over 24 km/h and its central convection became significantly eroded and was displaced to the north-east as Talas was exposed to a very strong wind shear of over 50 knots (93 km/h; 58 mph) that made the Low level circulation center very distorted and difficult to pin-point,and was downgraded into a Tropical depression on September 4.The remnants continue to move north east and made landfall on Russian Federation,Sakhalin, Kril'on.
The Typhoon has sustained winds of 123km/h which is high enough to by certified as a Category one typhoon in the SSHS, however the JTWC classified the storm as a Tropical Storm, while the JMA classified it as a Severe Tropical Storm.

Tropical storm Noru 16w
Highest Maximum sustained winds:79km/h

Characteristics:Moved at a Fast speed of 65 km/h!!
History:On August 25, a Tropical wave developed near Minamitorishima, however due to the Fujiwhara effect, the much stronger system beside, Typhoon Talas, pulled the system slowly north.However due to a Omega block, the much stronger system, Talas, suddenly stayed stationary, and a strong high pressure at the north east caused the tropical wave to move south west towards warmer waters and lower wind shears, which caused the system to develop a circulation ceneter and was certified as a Tropical disturbance on September 2, and a few hours later it was upgraded into a Tropical depression by the JMA and the Typhoon Storm Watch.The JTWC to issue a tropical cyclone formation alert.Soon, 16W accelerated north at over 33 km/h with its Low level circulation center being being consolidated by convection. Also, data from an ASCAT scatterometer pass revealed that the Low level circulation center was tightly wrapped with 74 km/h winds prompting the TSW and the JTWC to upgrade 16W to a tropical storm. As 16W continued to accelerate north at a staggering 65 km/h and convective banding became fragmented and detached behind the main area of central convection.However, the outflow to the southeast of the storm remained favorable and 16W continued to strengthen, prompting the JMA upgraded the system to a tropical storm, naming it Noru. Later the JTWC downgraded Noru into a tropical depression.

Kulap remained small in size and dry air entering from the western periphery kept it from strengthening further.Wind shear increased, pushing convection approximately 180 nautical miles (330 km; 210 mi) south of the LLCC. Also, Kulap was located beneath a tropical upper tropospheric trough(TUTT cell) that caused subsidence. A mid-level subtropical steering ridge cuased Kulap to track in a northwestward direction. On September 8, Kulap moved into the east-northeast periphery of the Philippine Area of Responsibility (PAR) prompting the PAGASA to start issuing advisories on the system, naming it Nonoy. However, Kulap quickly accelerated north and exited the PAR on the same evening, tromping the PAGASA to issued their final advisory on the system.Late on September 8, the JTWC downgraded Kulap to a tropical depression,with maximum sustained winds of 64km/h.Kulap later made landfall on Suwanose island, japan, which is a small island-only 10km across.It soon entered the southern part of the south china sea as well as passing into a area of warmer waters reach soon lead to an explosion of cloud production and the center wasn't exposed anymore.Early on September 10, the JMA too downgraded Kulap to a tropical depression, as it make its 2nd landfall on Jeju-do, South Korea.The remants soon dissipated completely on September 11

History:On September 3, Tropical Storm Noru extended a trough of low pressure which slowly moved south west and developed into a Tropical wave(It was as if Tropical Storm Noru placed a seed which develop into this system!).On September 6 the system develop a circulation center and on September 7 the Typhoon Storm Watch upgraded the low as a Tropical disturbance, as it moved towards warmer waters.Late on September 8, the Typhoon Storm Watch and the JMA upgraded the disturbance to a tropical depression northeast of the Northern Mariana Islands, with sustained winds of 55km/h.Over the next two days, the system gradually drifted west and intensified slightly, prompting the JTWC to issue a Tropical Cyclone Formation Alert (TCFA) on it.Convection gradually consolidated the LLCC and the JTWC initiated advisories on the system on September 11, designating it with 18W.The next day, PAGASA assigned the name Onyok to the depression.The system was slowly moving west but started to change direction towards east,and at the same time, TD 18w's low level circulation center became exposed.But as it moved west again the low level circulation center wasn't exposed but it soon became exposed again 5 hours later.On September 13, The Typhoon Storm Watch and the JMA upgraded Tropical depression 18w to a tropical storm and named it Roke.Due to a Strong High pressure in the north, TS Roke moves south east.Roke soon drifted over the southern side of Minami-Daito, Japan on September 15.On September 16 the southern side of the system,as well as the remnants of a Tropical depression brought humid moist air from the south towards the the Circulation of the system and the system started to strengthen as well as increased cloud production.Early on September 17,TS Roke intensified further into a Severe Tropical Storm as well as absorbing the remnants of a Tropical depression(unnamed).On September 18,Roke unexpectedly moved south due to a slight Fujiwhara effect between Roke and Sonca,which later caused the storm to made a small cyclonic Loop.On September 19 the storm develop a weak slightly visible eye but quickly dissipated three hours later.In the evening of September 19, STS Roke intensified unexpectedly into a Category one typhoon and developed a 45 kilometers across medium eye, due to the fact that it was drifting into a patch of warmer waters which fueled the storm.
Early on September 20 the Storm Instantly and unexpectedly continue to undergo a rare case of Explosive Rapid intensification that involves a tropical cyclone deepening at a rate of at least 2.5 mbar per hour for a minimum of 12 hours. Roke Intensified into a Category 3 Typhoon within 4 hours with Maximum winds of 185km/h.Roke soon weakened slightly into a Category Two but in the evening of September 20.But again undergo Explosive Rapid intensification into a Category four Typhoon with winds of 217km/h.At the same time, on the southern part of jeju-do island,south korea, Von-Karman Vortices formed due to the convection on the west side of Roke that moves south east.

Meteorological History:One of the most destutive typhoons of the season formed on September 17, as a Tropical wave which developed near Micronesia and moved west, forming close to the equator.On September 18 it developed a Circulation center,so the Typhoon storm Watch upgraded the system as a Tropical disturbance.On September 23 the system rapidly organized and was upgraded into a Tropical Depression by the Typhoon Storm Watch and the JMA with winds of 55km/h and was located about 400 kilometers from Yap Island.
The JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the depression.Soon that day, convection rapidly consolidated the center with persistent, prompting the JTWC to initiate advisories on the system, designating it with 20W.At midnight, that day, the JMA further upgraded 20W to a Tropical Storm and named it Nesat.Nesat steadily intensified into a Severe Tropical Storm and later a Category 1 Typhoon as its outer rain bands start to brush eastern Philippines.JMA also upgraded nesat as a Typhoon early on September 26,as Nesat develops a eye wall.Late on September 26, Typhoon Nesat undergo Explosive,Rapid
The Hong Kong Observatory soon issued the Typhoon Signal No.3 in Hong Kong as Nesat enters the 800 kilometer boundary form Hong Kong.On September 29 the Hong Kong Observatory issued the Strong Wind Signal or Typhoon Signal No.8 as Typhoon Nesat soon came at it's closest at 350 kilometers from Hong Kong.Nesat also stated to develop a Large eye at 100 kilometers across,but the eye soon decrease in size to 50 kilometers across.Typhoon Nesat soon made landfall at Wenchang, Hainan, China on the evening of September 29,as the eye dissipated.Nesat soon entered the Gulf of Token before its second making its second landfall at Hai Phong, Hai Duong, Vietnam on 8 O'clock Hong Kong Time.Nesat rapidly weakened inro a low pressure area which soon moved north and then north west until it dissipated completely as it drifts over northern Shanghai.

Fatalities:957
Damage:$27million(2011 USD)
Duration:December 13 – December 19
History:On December 10, a tropical wave formed and soon developed a circulation center the next day.it was upgraded as a tropical disturbance on December 12,and later a Tropical depression on December 13. The JTWC upgraded designated the system, 27W.Despite lacking the Coriolis effect,a High pressure in the west helped 27w's convection,and helped it to spin.Washi soon strengthened into a Tropical Storm,but soon weaken back into a tropical depression.It later strengthned again into a tropical storm.Washi soon reached peak intensity on December 17,and later entered the south china sea,and dissipated quickly due to unfavorable conditions.
Washi has caused at least 1,236 fatalities and 1000 people are currently missing in the Philippines.The majority of the deaths were in the cities of Iligan and Cagayan de Oro. Five people were killed in a landslide, but all others died in flash flooding. More than 2,000 have been rescued, according to the Armed Forces of the Philippines.
