ABSTRACT
Late spring (21 April-20 May) precipitation to the south of the Yangtze River in China along the East Asian front is a salient feature of the global climate. The present analysis reveals that during 1958-2000 South China (26°-31°N, 110°0 -122°E) has undergone a significant decrease in late spring precipitation since the late 1970s. The sudden reduction of the precipitation concurs with a notable cooling in the upper troposphere over the central China (30°0 -40°N, 95°-125°E). The upper-level cooling is associated with an anomalous meridional cell with descending motions in the latitudes 26°-35°N and low-level northerly winds over southeastern China (22°0 -30°N, 110°0 ...
