Simulation of the response of the Hadley cell and extratropical troposphere stratification on the climate changes using a general atmosphere circulation of medium complexity

In this paper, the response of the general atmosphere circulation to the climate changes is simulated with use of a medium complexity model. It is shown that with a temperature gradient decrease, the Hadley circulation weakens and its boundary moves to the poles. The troposphere height dynamics depending on atmosphere temperature is investigated. A relation between characteristics determining the atmosphere baroclinic instability is obtained.
