The 2012 Pacific typhoon season is an event in which tropical cyclones form in the Western Pacific Ocean. The season will run throughout 2012 with most tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean to the north of the equator between 100th meridian east and the 180th meridian. Within the Northwestern Pacific Ocean, there are two separate agencies who assign names to tropical cyclones which can often result in a cyclone having two names. The Japan Meteorological Agency will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h, (40 mph) anywhere in the basin. Whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N even if the cyclone has had a name assigned to it by the Japan Meteorological Agency. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center are given a number with a "W" suffix. On average, 27 storms form in this basin every year.

Seasonal forecasts

Each season several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country.

Storms

Tropical Depression

Tropical depression (JMA)
 
DurationJanuary 13 – January 14
Peak intensity55 km/h (35 mph) (10-min);
1006 hPa (mbar)

On January 13, the JMA upgraded a low pressure area to a tropical depression, east-northeast of Singapore. However, the depression quickly dissipated on January 14, due to the high wind shear. A few landslides have been reported when it dissipated over Malaysia, however no damage from the storm was reported.

Storm names

Within the Northwestern Pacific Ocean, there are two separate agencies who assign names to tropical cyclones which often results in a cyclone having two names. The Japan Meteorological Agency names tropical cyclones should they be judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph), to the north of the equator between the 180° and 100°E. Whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°E-25°E even if the cyclone has had a name assigned to it by the Japan Meteorological Agency. Unused names are marked in gray.

International names

See also: Lists of tropical cyclone names and Tropical cyclone naming

Tropical Cyclones are named from the following lists by the Regional Specialized Meteorological Centre in Tokyo, Japan, once they reach tropical storm strength.[1] Names are contributed by members of the ESCAP/WMO Typhoon Committee. Each of the 14 nations or territories submitted 10 names, which are used in alphabetical order, by the English name of the country.[2] The next 24 names on the naming list are listed here.

Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. The names not retired from this list will be used again in the 2016 season. This is the same list used in the 2008 season except for Frank which was retired. Names that were not assigned/going to use are marked in gray.[3]

Season effects

This table lists all the storms that developed in the western Pacific Ocean to the west of the International Date Line during the 2011 season. It includes their intensity, duration, name, landfalls, deaths, and damages. All damage figures are in 2011 USD. Damages and deaths from a storm include when the storm was a precursor wave, or an extratropical low.
