Relationship of Temperature Variation between in the Stratosphere and the Troposphere

Abstract The temperature variation in the stratosphere is very important in the global climate system. It is considered to be the key to study atmospheric temperature vertical profiles, ozone and water vapor. The temperature change in some layers from the mid-troposphere to the upper stratosphere was analyzed by using monthly mean temperature data of ECMWF reanalysis. The research results show that: (1) From 1958 to 2001, there are some differences of the temperature variation in each layer in the troposphere and the stratosphere, the global temperature in the mid-troposphere and mid-stratosphere rises remarkably, but it decreases in the lower and upper stratosphere. (2) In summer and winter, the temperature variation in each layer is almost the same. More over, the change is clearer in summer than that in winter. (3) There is a close relationship of the temperature variation between in stratosphere and in troposphere.
