Winter monsoon impacts summer monsoon and rainfall patterns in China.
The study looked at how the winter monsoon affects the summer monsoon through interactions between the air and sea. They found that the sea surface temperature near Xisha is linked to the East Asia winter monsoon. This abnormal sea temperature tends to continue into the summer monsoon season. Rainfall in China is also influenced by the sea temperature near Xisha, with positive correlations in certain regions during different months. The air-sea interaction is crucial in these processes.
