In April 2020, weak positive equatorial sea surface temperature (SST) anomalies were observed over the equatorial Pacific. Suppressed tropical convection near Indonesia and the Date Line was persisted, while wind anomalies near the Date Line were easterly. Positive monthly mean temperature anomalies were observed over the Arctic, Antarctic, and Central Russia, whereas negative anomalies spanned over East Asia, Central Asia, western Russia, Canada, and northern USA. Positive monthly mean precipitation anomalies were observed along the region from Iran to the Horn of Africa, eastern Indian Ocean near Australia, and southeastern Australia. Negative anomalies spanned over Central Russia, Mongolia, northern China, Europe (excluding Northern Europe), equatorial Pacific, and Timor, Arafura, and Coral Seas.
For timely detection and monitoring of major climate events over the Asia-Pacific region, the latest observed weekly, monthly and seasonal mean values of 2m temperature (T2M), outgoing long wave radiation (OLR), rainfall (RAIN), sea surface temperature (SST), surface wind at 10m (Wind10m) and geopotential height at 500hPa (Z500) are provided.
