Abstract EN
In January 2008, extreme freezing rain struck South China.
At the same time, the Tibetan Plateau (TP) was experiencing pronounced surface heating.
The characteristics of this extreme weather and its linkage to the TP surface heating anomaly were analyzed in this paper.
The results show that (1) anomalous heating of the TP helps to form and sustain the Siberian blocking high, which is important for persistent southward flow of dry and cold Siberian air; (2) TP heating helps the moisture flux move more north and strengthens the southerly wind above 850 hPa; (3) there are two Rossby wave trains at 500 hPa and the layers above it (at about 20∘N–40∘N).
Correlation analysis reveals that TP heating anomalies are closely associated with these Rossby wave trains; (4) the Rossby wave propagates downstream from the TP to South China in the mid and high layers of the atmosphere when the TP changes swiftly from a heat sink to a heat source.
This implies that anomalous heating of the TP may stimulate the Rossby wave train to propagate downward in midlatitudes.
