The Philippine Area of Responsibility (PAR) is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency, monitors weather occurrences. Significant weather disturbances, specifically tropical cyclones that enter or develop in the PAR, are given Philippine-specific names .
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Pilipinas sa Serbisyong Atmosperiko, Heopisiko at Astronomiko, [4] abbreviated as PAGASA, which means "hope" as in the Tagalog word pag-asa) is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities ...
The interchangeability of pressure and wind allows for the two to be used to give equivalencies for the public. [7] Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [6] Some storms may have particularly high or low pressures that do not match with their wind speed.
ASOS sensors, located at Salinas, California. Surface weather observations have traditionally been taken at airports due to safety concerns during takeoffs and landings. The ICAO defines the International Standard Atmosphere (also known as ICAO Standard Atmosphere), which is the model of the standard variation of pressure, temperature, density, and viscosity with elevation/altitude in the ...
A col, also called saddle point or neutral point, is in meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map. It takes the form of a saddle where the air pressure is relatively higher than that of the low-pressure regions, but lower than that of the anticyclonic zones. [1]
Typhoon Ewiniar, known in the Philippines as Typhoon Aghon, was a fairly strong tropical cyclone that impacted parts of the Philippines, particularly Luzon, in May 2024. The first named storm and typhoon of the annual typhoon season , Ewiniar emerged from an area of atmospheric convection 441 km (274 mi) southeast of Palau .
