Abstract
Experimental data on variations in atmospheric surface pressure in the region of thunderstorm phenomena are analyzed. A relationship between variations in atmospheric pressure at the land surface and those in tropospheric temperature has been found, and the relation between the vertical distribution of tropospheric temperature and variations in atmospheric pressure at the land surface is studied. The propagation of internal gravity waves caused by atmospheric heating due to water-vapor condensation during the formation of a convective cloud is simulated. The results of calculations show that the lifetime of these internal gravity waves may significantly exceed the lifetime of this cloud. It is shown that the form of the disturbance of atmospheric pressure under such a convective cloud is a sequence of minimum and maximum pressure variations and the amplitude of maxima may exceed that of minima.
