Current Climate Conditions
In February 2019, El Niño conditions developed. The equatorial sea surface temperatures (SSTs) remained warmer than average across most of the tropical Pacific Ocean. Positive sub-surface temperature anomalies were strengthened across most of the equatorial Pacific. Convection and the westerly wind anomalies near the Date Line were observed. Positive monthly mean temperature anomalies exceeding +5°C prevailed over the western Arctic, eastern Antarctic, and the central Siberia. Negative seasonal mean temperature anomalies were observed over the eastern Arctic, Canada, northern USA, eastern Siberia, Mongolia, and North Africa. Positive precipitation anomalies prevailed over the western tropical Pacific, northeastern North Pacific, USA, and North Africa. Negative precipitation anomalies spanned the maritime continent, eastern Indian Ocean, northern Australia, central tropical Pacific, northeastern North Pacific near Canada, and the western Arctic.
For timely detection and monitoring of major climate events over the Asia-Pacific region, the latest observed weekly, monthly and seasonal mean values of surface temperature (TSFC), outgoing long wave radiation (OLR), rainfall (RAIN), sea surface temperature (SST), surface wind (UV850) and geopotential height at 500hPa (Z500) are provided.
