地面对晴空大气热辐射结构的影响
ROLE OF SURFACE FORCING ON THE ATMOS-PHERIC RADIATIVE FLUX DIVERGENCE PROFILES

摘要: 本文利用1987年美国FIFE资料及1986年6月TIPMEX资料,并利用大气长、短波一维辐射传输数值模式,计算了晴空大气状态下地面辐射参数(地面热辐射温度、地表反照率等)对大气长波冷却率、短波加热率廓线的影响。结果表明,地球表面对大气边界层内的热辐射结构影响很大,特别是在高原地区这种影响尤其显著。Abstract: By using the FIFE and TIPMEX-86 experiment data, the results of surface forcing on the atmospheric radiative flux divergence profiles and the bulk atmospheric cooling (heating) rates (both longwave and shortwave) are presented. Analyses indicate that surface properties takes a great role on the radiative flux divergence within boundary layer atmospheres, especially over the Tibetan plateau.
