应用美国宇航局Goddard地球观测系统（GoddardEarthObservingSystem简称GEOS）四维资料同化系统（DataAssimilationSystem简称DAS），计算和分析了50°S以南海域夏季的感热、潜热通量．结果表明，在50°S以南海域潜热通量都为正值，感热通量在大部分海域亦为正值，但在有些海域可出现负值．感热和潜热通量随纬向呈高值区和低值区交替分布，通量低值区与海表温度低值槽区往往相符．
The sensible and latent heat fluxes of the summer south of 50 ° S were calculated and analyzed using NASA’s Goddard Earth Observing System (GEOS) 4-D Data Assimilation System (DAS). The results show that the latent heat flux in the sea area south of 50 ° S is positive, and the sensible heat flux is also positive in most of the sea areas, but may be negative in some areas. The sensible and latent heat fluxes alternate with high and low values in zonal direction, and the low fluxes tend to coincide with the low troughs of sea surface temperature.
