Rainfall anomaly visualizes severe drought in China's Yunnan province

The province of Yunnan, China is experiencing a record-breaking drought that has been deepening since September 2009.   River water levels, including the mighty Mekong, are  subsiding well below normal, and many reservoirs are nearly dry. Millions of people, as well as agricultural activities in the province are affected due to severe water shortages.

Accuweather has a recent report on the drought: 
Severe Drought Continues for China's Yunnan Province
 

NASA TRMM Multi-Satellite Precipitation Analysis products provide a near-real-time capability for drought and flood watches on a global scale. The figure below shows a map of rainfall  deficits (in percent) in the Yunnan region.   This image demonstrates that a large area  of Yunnan province and areas in several adjacent provinces are affected.  Over the period September 2009-February 2010, the rainfall deficits are 50-60% below normal for many areas  and below 70% in the worst-hit regions.
