Distinct response of near surface air temperature to clouds in North China

Abstract Using the daily 2 m maximum temperature (Tmax), minimum (Tmin) and cloud cover data measured at ground sites of China Meteorological Administration in North from 2000 to 2017, this study investigates influence clouds on range (DTR) defined as difference between Tmax Tmin. As expected, shows similar averaged spatial distribution monthly variation with Surprisingly, it also average Tmax, suggesting more important roles regions (latitude) seasons associated variations land surface temperature, which is further related solar radiation absorbed heat capacity. By comparing cloudy clear skies, we find that can weaken increase Tmin, thus decrease DTR. a result, DTR opposite cover. The have relatively stronger impact Tmin over mountain region, most likely caused by longwave radiative forcing higher tops region.
