The Calculation of the Annual Variations in the Longwave Radiation Balance of the Atmospheric Boundary Layer at Wakkanai, Wajima, Tateno and Kagoshima

Abstract

In this paper the air layer between the ground and the 850mb surfaces are taken as the atmospheric boundary layer. First, the longwave radiation balance of the atmospheric boundary layer at every 2100JST in the whole year of 1975 are theoretically computed from radiosonde data at four stations in Japan. Then the theoretically computed results are parameterized in terms of air temperature and water vapor pressure at screen level and cloudiness.
