Abstract

In Part I of this paper, influence functions are derived for the response of a quasi-geostrophic atmosphere to transient heat sources and sinks, assuming that the effects of horizontal advection can be neglected and assuming a fairly reasonable vertical distribution of static stability. The influence is studied for diabatic heating of different horizontal wavelengths and for two different types of the vertical distribution. In Type I, heating is largest at the ground, decreasing to zero at p = 0. In Type II, heating is maximum in the middle atmosphere and decreases parabolically to zero at p = 0 and at the ground. It is shown that, in both types, the horizontal wavelength L of the heating function is very important in determining not only the intensity of pressure fall in the lower levels and of pressure rise aloft in the region of heating, but also the level of maximum pressure effect. It is seen that wavelengths of the order of 15,000 km produce maximum geopotential variations around the 150-mb level
