The Philippine Area of Responsibility (PAR) for tropical cyclone warnings

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Palingkurang Atmosperiko, Heopisikal at Astronomiko ng Pilipinas, abbreviated as PAGASA, which means "hope" in Filipino) is a Philippine national institution dedicated to provide flood and typhoon warnings, public weather forecasts and advisories, meteorological, astronomical, climatological, and other specialized information and services primarily for the protection of life and property and in support of economic, productivity and sustainable development. The government agency was created on December 8, 1972 by virtue of Presidential Decree No. 78. The Presidential decree reorganized the Weather Bureau into PAGASA.[1]

[edit] Tropical Cyclones

PAGASA monitors tropical cyclone activity and issues warnings within its area of responsibility. This area is bound by an imaginary line drawn along the following coordinates:

25°N 120°E, 25°N 135°E, 5°N 135°E, 5°N 115°E, 15°N 115°E, 21°N 120°E and back to the beginning.[2]

Tropical cyclone bulletins are issued by PAGASA every six hours for all tropical cyclones within this area that have or are anticipated to make landfall within the Philippines, or twelve hours when cyclones are not affecting land. On August 27, 2007, Pagasa announced that it was putting up a tornado warning system, days after several more powerful and destructive tornadoes damaged houses in Central Luzon, the monsoon and climate change. On August 23, 2007, a 2nd tornado destroyed 30 houses in 4 villages in San Miguel, Bulacan, the first having damaged 27 houses in San Rafael on Aug. 8.[3]

[edit] Climatology

The climate of the Philippines is discussed in detail on the Climatology page of the PAGASA website. [4]

PAGASA lists patterns of Temperature, Humidity, Rainfall, Seasons, and four Climate Types, for the Philippines.

Climate Types are:

  • Type 1 - Two pronounced seasons: Dry from November to April, Wet rest of the year.
  • Type 2 - No dry season, but with heavier rainfall November to January.
  • Type 3 - No pronounced seasons, but often drier from November to April.
  • Type 4 - Rains all year. [5]

[edit] Criticism

PAGASA was criticized for giving inaccurate forecasts. One of its notable inaccuracies was during the height of typhoon Unding (Muifa) in 2004, where it forecast a northern movement of the storm when it stalled off the Bicol Region. Like what was forecasted by other weather agencies, Unding made its tight loop and lashed through Naga and Mindoro by November 19.[6][7] As a result, people tend to get typhoon information on other sources instead, such as the Internet. PAGASA however blamed their inaccuracies on their outdated equipment and hope for updated equipment in the future.[8]
