INFLUENCE OF FOREST CANOPY ON RAIN PRECIPITATION INTERCEPTION, PENETRATION, AND DISTRIBUTION

A. V. Volokitina and M. A. Sofronov

Data on interception of rain precipitation by a canopy of coniferous plantation are analyzed. Rain distribution under the canopies of various woods in different areas is investigated using a dense raingage network. Three typical variants of rain precipitation distribution were determined: irregular distribution with a permanent occurrence of the driest spots close to the trunk feet typical of spruce and fir taiga stands; irregular distribution with a variation of its character under the wind effects typical of pine and larch taiga stands; relatively regular distribution typical of the northern Siberian stands with an open canopy. The rain distribution can affect the conditions of the appearance and growth of self-seeding, the character of burning, and the consequences of ground fires. These regularities can be useful in hydrological and meteorological investigations in forests.
