Monthly Western Hemisphere Warm Pool (WHWP)Entry ID: NOAA_NWS_CPC_WHWP
Abstract: [Source: NOAA/ESRL/PSD, http://www.esrl.noaa.gov/psd/ ]
The Western Hemisphere Warm Pool (WHWP) monthly anomaly of the ocean surface area warmer than 28.5B0C in the Atlantic and eastern North Pacific. Climatology is 1951-2000.
The WHWMP develops west of Central America in the spring, then expands to the tropical waters to the east. WHWP development Enlarge WHWP ... development. The WHWP includes the tropical Atlantic Ocean (TNA) east of the Lesser Antilles, Caribbean Sea, Gulf of Mexico, and eastern north Pacific Ocean (NPA).
A WHWP heating cycle begins with warmth in the eastern North Pacific in the spring. A dipole pattern off Central America appears due to cold air from the Gulf of Mexico blowing south with mountain jet influence, with warm pools on each side. During boreal spring, the warm pools grow and merge. The warmth and moisture feed the Mexico monsoons, and warmth spreads across the Gulf of Mexico and Caribbean areas.
The WHWP is correlated with the Tropical North Atlantic index.
