利用南极冰盖表面物质平衡的最新汇编和南部海洋部分的降水和蒸发的新估计，以及冰盖特定部分的向海漂移雪运输的新估计，估算了70年代向极地的年净大气水汽和潜热输送。在该纬度范围内，严格地综合了冰盖-大气和海洋-大气界面的质量和能量交换率。基于在66oS和80oS之间的站点收集的大气平流和水分数据，估算的净南向水汽输送（6.6 + 1.3 kg m -1 s -1）和潜热输送（18.9 + 3.6 MJ m -1 s -1）比以往所有研究报告的都要大，并且与基于地表质量平衡数据和横跨65oS和79oS之间的冰端向海漂移雪输送的结果基本一致。
The annual net atmospheric transports of water vapor and latent heat poleward across 70oS are estimated using the latest compilation of surface mass balance for the Antarctic ice sheet and new estimates of precipitation and evaporation in sectors of the southern oceans and of seaward drifting snow transport in particular sectors of the ice sheet. The mass and energy exchange rates at the ice sheet-atmosphere and ocean-atmosphere interfaces are integrated strictly for areas within that latitude. The estimates of net southward water vapor transport (6.6 + 1.3 kg m -1 s -1) and latent heat transport (18.9 + 3.6 MJ m -1 s -1) are larger than reported in all preceding studies, based on atmospheric advection and moisture data collected at stations located between 66oS and 80oS, and are generally in agreement with those based on surface mass balance data and seaward drifting snow transport across the ice terminus which extends between 65oS and 79oS.
