The authors discovered that there is a clear reversal of seasonal changes between winter and summer wind, just like the classic monsoon. Accordingly, the authors propose the new concept of the upper- troposphere monsoon over the CETP. The results extend the classical lower-troposphere monsoon region into the upper troposphere.展开更多
