2. 2 Outline Recent Rainfall and Current Conditions Monsoon Prediction Summary Climatology

3. 3 Precip Patterns: Last 90 Days For the past 90 days, the rainfall amounts over all of India except in the northeast and almost over all of China except in the region bordering Burma is at near or slightly above normal levels. However, northern Australia, Koreas, Japan, and over major parts of southeast Asian countries essentially including Thailand, Laos, Cambodia and Vietnams, rainfall has been below normal.

4. 4 Precip Patterns: Last 30 Days For the past 30 days, rainfall is below normal over central India and considerably below normal in all southeast Asian countries east of Burma. However, rainfall is above normal over southeastern China.

5. 5 Precip Patterns: Last 7 Days In this past week, the India Meteorological Dept. (IMD) has declared the onset of 2014 summer monsoon rainfall over the state of Kerala on the 6 th of June and that the monsoon has fully covered the states of Tamil Nadu and Kerala by the 9 th of June. Central India remains relatively dry this past week.

6. 6 Rainfall Time Series over 5x5 lat-lon boxes The time series of precipitation over the various regions is pretty much consistent with the spatial maps shown earlier.

9. 9 Summary For the past 90 days, the rainfall amounts over all of India except in the northeast and almost over all of China except in the region bordering Burma is at near or slightly above normal levels. However, northern Australia, Koreas, Japan, and over major parts of southeast Asian countries essentially including Thailand, Laos, Cambodia and Vietnams, rainfall has been below normal. For the past 30 days, rainfall is below normal over central India and considerably below normal in all southeast Asian countries east of Burma. However, rainfall is above normal over southeastern China. In this past week, the India Meteorological Dept. (IMD) has declared the onset of 2014 summer monsoon rainfall over the state of Kerala on the 6 th of June and that the monsoon has fully covered the states of Tamil Nadu and Kerala by the 9 th of June, which is consistent with the rainfall maps shown here. But central India remains relatively dry this past week. In the next week, the NCEP GFS model predicts below normal rainfall over large parts of India and much below normal over southeastern China but above normal rainfall over central China, Burma, and parts of Thailand, Laos and north Vietnam. A somewhat similar picture is also forecast for the second week except for southeastern China with above normal rainfall.
