Description
Summary:A two-level quasi-geostrophic model which includes the distribution of land and sea in the northern hemisphere with the effects of topography and heating taken into account is set up for a numerical study of the general circulation of the atmosphere. The influences of clouds on long and short-wave radiation in radiational heating are considered, with the assumption that the appearance of clouds depends only on the vertical current. The surface temperature is obtained by solving the heat conduction equation. The nonlinear ordinary differential equations derived are integrated numerically on an electronic computer using the Runge-Kutta method. The cool air over Asia and the Pacific and the warm air over Europe and the Atlantic in winter can be attributed to the thermal properties of the distribution of land and sea in the northern hemisphere. Topography and non-adiabatic heating are jointly responsible for the formation of troughs over East Asia and North America as well as for the cold-air activity which usually originates in Novaya Zemlya in Soviet Russia and migrates southeastward.
