English Abstract

This paper is to study the vertical energetic characteristics based on the ECMWF III-b data over 30°E ~ 150°E, 0 ~ 60°N during May and June, 1979. Firstly, the time variations of the vertical temperature profile in mid-latitudes are significantly observed. The major time change is close to that of the onset and recess of the East Asia Mei-Yu seasons. Secondly, Most of the 80 energy stored in the first four vertical modes is dominant over the tropics. The calculated energy shows there are a 30 day period variations for the first vertical mode in the tropics and 15 day period oscillations revealed in internal and first modes of the mid-latitudes. Besides, it appears seemingly a transient belt in the subtropic regions.Potential energy is dominant in the tropics, in the first vertial mode of the subtropics and mid-latitudes. However kinetic energy is most important over the internal modes in the subtropics and mid-latitudes.
