The Asian-Australian Monsoon System: Recent Evolution, Current Status and Prediction Update prepared by Climate Prediction Center / NCEP April 22, 2019 For more information, visit:http://www.cpc.ncep.noaa.gov/products/Global_Monsoons/Asian_Monsoons/Asian_Monsoons.shtml
Outline • Recent Rainfall and Current Conditions • Monsoon Prediction • Summary • Climatology
Precip Patterns: Last 90 Days For the past 90 days, below normal rainfall deficits dominated deep southern coastal peninsular India, Korea, Japan, Malaysia, parts of New Guinea island of Indonesia and Papua New Guinea, and almost all of Australia, particularly north western regions. Elsewhere, the rainfall amounts received were at normal to slightly above normal levels, particularly in southeastern China, Kashmir India, Nepal, parts of the Middle East, and Indonesia.
Precip Patterns: Last 30 Days For the past 30 days, slightly above normal rainfall scatterd-ly across the Middle East,. Elsewhere the rainfall amounts received were mixed.
Precip Patterns: Last 7 Days In this past week, overall, above normal rainfall fell across the Middle East, and below normal fell across southeast Asia. Almost no rainfall fell over Australia.
Atmospheric Circulation Generally these CDAS maps are two days behind. But sometimes, as it is today, due to technical issues, these maps are further behind.
Rainfall Time Seriesover 5x5 lat-lon boxes The time series of precipitation over the various regions is pretty much consistent with the spatial maps shown earlier.

Summary For the past 90 days, below normal rainfall deficits dominated deep southern coastal peninsular India, Korea, Japan, Malaysia, parts of New Guinea island of Indonesia and Papua New Guinea, and almost all of Australia, particularly north western regions. Elsewhere, the rainfall amounts received were at normal to slightly above normal levels, particularly in southeastern China, Kashmir India, Nepal, parts of the Middle East, and Indonesia. For the past 30 days, slightly above normal rainfall in a scattered fashion across the Middle East,. Elsewhere the rainfall amounts received were mixed. In this past week, overall, above normal rainfall fell across the Middle East, and below normal fell across southeast Asia. Almost no rainfall fell over Australia. For the next two weeks, the NCEP GFS model forecasts rainfall occurring over deep southern India, above rainfall over southeast China, Burma, but below normal rainfall elsewhere.
