Abstract EN
Timely and accurate monitoring of droughts is important for implementing an effective response and for minimizing economic losses.
In this paper, the duration and amount of deficit in precipitation before every severe drought were analyzed for 124 meteorological stations based on the weather data from 1961 to 2012.
The results showed that deficit in precipitation over a period as short as three months or even shorter could lead to severe drought and the cumulative timescales of precipitation deficit in southwestern China were longer than those in southern China.
The distribution of the critical amount of precipitation deficit showed a clear regional difference.
Deficits in the western parts of southwestern China and parts of southern China are above 60%, or even above 80%, higher than the other area ranging between 40% and 60%.
On the whole, the critical amount of the deficit preceding severe droughts for the humid southwestern and southern China was lower than that for the semiarid and semihumid areas.
The results offer a sound basis for monitoring and forecasting droughts in southern and southwestern China and for issuing early warnings.
