The results of direct measurements of turbulent fluxes at Bellingshausen station (the Antarctic) in the summer of 2002, 2003, 2007, and 2009 are considered. The features of energy exchange are studied for these seasons. The interannual and intraseasonal variability of energy exchange characteristics is investigated. It is found that heat fluxes depend on the surface state and on the wind direction. Also, as a rule, they have a clear diurnal course with negative or near-zero values at night and with positive values in the daytime, when intensive convective fluxes are observed over open ground. The momentum flux is defined by the wind direction and wind speed and by stratification conditions. The main factors affecting energy exchange between the atmosphere and the surface in the Antarctic coastal zone are synoptic conditions and the surface state (snowless season duration and moss cover presence).

通过仪器观测得出的南极沿海地区的空气—表面湍流热交换

考虑了2002年，2003年，2007年和2009年夏季在贝灵斯豪森站（南极）的湍流通量的直接测量结果。这些季节研究了能量交换的特征。研究了能量交换特征的年际和季节内变化。发现热通量取决于表面状态和风向。而且，通常，当在开阔的地面上观测到强对流通量时，它们的昼夜过程清晰，夜间为负或接近零，白天为正值。动量通量由风向和风速以及分层条件定义。
