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 ...
A major key to shaping weather patterns worldwide is found in the tropical Pacific Ocean, far from any mainland. Known as the El Niño-Southern Oscillation (ENSO), this climate phenomenon is the ...
[15] [16] In mid-January 2023, weather forecasts regarding the probable occurrence of the El Niño phenomenon in 2023 and 2024 were published in various media. [ 17 ] [ 18 ] [ 19 ] Given that Earth's average temperature has already increased by 1.2 °C since pre-industrial times, a large enough El Niño event in 2023-2024 could even push the ...
In El Niño years, NOAA says, rain clouds form over the warm ocean water and move inland, dropping more rain than usual in South and Central America and the U.S.
The effects of El Niño on rainfall in southern Africa differ between the summer and winter rainfall areas. Winter rainfall areas tend to get higher rainfall than normal and summer rainfall areas tend to get less rain. The effect on the summer rainfall areas is stronger and has led to severe drought in strong El Niño events. [174] [175]

Weakening sea surface temperature anomalies in the tropical Pacific in early 2023 associated with the end of the La Niña event. The 2020–2023 La Niña event was unusual in that it featured three consecutive years of La Niña conditions (also called a "triple-dip" La Niña) in contrast to the typical 9–12 month cycles of the El Niño–Southern Oscillation (ENSO), [3] though the magnitude ...
