Observational Study of Annual Variations of the Surface Energy Balance Components at Zhongshan Station of Antarctica in 1990

From February 1990 to January 1991, the measurement experiment was carried out at Zhongshan station, East Antarctica. In the experiment, measurements of the surface radiative fluxes and wind, temperature and humidity profiles in the lowest 32 m in the atmosphere boundary layer were made throughout the year. The regime of the surface energy balance was analysed based on the observed data. The conclusion was derived that in warm season (from Nov. to Feb.), large amounts of energy are absorbed by the surface and then transported to the atmosphere in the form of sensible and latent heat, while in cold season (from Mar. to Oct.) continually radiative cooling of the surface occurs.     

南极中山站1990年地表能量通量变化的观测研究

1990年2月—1991年1月在中国南极中山站开展了辐射和近地面梯度观测实验,获得了一个完整年的辐射和大气最下层32m的风速、气温和湿度梯度资料。本文依据这些资料分析了中山站地表能量平衡各分量的年变化特征。结果表明,暖季(11—2月)地表吸收大量热量并以感热和潜热方式向大气输送,寒季(3—10月)地表为持续的辐射冷却,并以感热方式从大气中获得热量。
