ON THE ABILITY OF ATMOSPHERIC VAPOROUS WATER TO CONDENSATE WITHIN THE SOIL ON THE BACKGROUND OF THERMAL BALANCE AND EXPERIMENTAL MATERIALS
Abstract
On the basis of experimental works considering the condensation of vaporous atmospheric water within the soil, A.A. Rode concluded that the summer night water condensation in dry surface soil layers with volume 0.1-0.2 mm is a common phenomenon. Along with that, the possibility of atmospheric water condensation in the aeration zone and on the level of ground waters has insufficient stipulation. However, the latest investigations allow us to state that the condensation of atmospheric moisture is impossible in the zone of aeration and at the level of ground waters. Movement of vaporous waters is carried out on a background of water stores contained within the soil, and are subjected to the seasonal and daily rhythms of warmth flows. The volume of the transfer is proportional to the flow. It is experimentally set that during the period of summer warming of the aeration zone on the key plot of sands of Volga Region through 1 cm2 of horizontal surface at the depth of 50 cm 3 000 cal. of warmth penetrates into the lower layers. At the depth of 100 cm it contains 2 500 cal., at the depth of 200 cm - 1 700 cal., and at the depth of 300 cm - 1 000 cal. correspondingly. Hence, the vapor transfer within the soil into the lower layers of the soil contained 5.1, 3.3, 2.0 and 1.2 mm. The same values of transfer, but backwards are detected during the cold period of the year. The movement of vaporous water is completely faded within the zone of constant temperatures.
