In the 2010 general election the Sweden Democrats for the first time crossed the four per cent threshold necessary for parliamentary representation.
Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies.
Factors controlling rates of evapotranspiration. The rate of evapotranspiration-and thus the amount evapotranspired over a given time-depends on three atmospheric conditions: energy availability, wind speed and moisture gradient (Fig.1). Energy must be available to convert the liquid water into vapor.
