Evaporation from the mires of the Kola Peninsula

Abstract

The article considers the data of long-term observations of evaporation from the mires of the Kola Peninsula. The main factors affecting evaporation from mires are the heating of the evaporating surface, the moisture supply, the vegetation cover and its developmental stage. The main contribution to the total evaporation is due to transpiration of vegetation (98 %). Lichen cover significantly reduces evaporation. The intra-seasonal pattern of evaporation from mires micro-landscapes are in good agreement as to phases, but differ in extent. The correlation of evaporation among individual micro-landscapes, micro-relief and open water surface was revealed. The influence of the degree of development of the microrelief on the amount of evaporation was found.
