本文研究了海陆及大地形对温度纬圈距平场的影响。研究指出夏季亚欧大陆及青藏高原所在的北半球东半部是全球各半球中最暖的半球,海陆地形对温度场的直接影响,因海陆地形的大小而不同,范围和强度以地面为最大最强,然后随高度减小,在300-200毫巴出现一个第二大值带。这是由于地面感热加热和降水潜热加热作用不同所造成的。夏季高原大地形加强了陆地的加热作用,影响范围远远超过了地形本身。另外,也讨论了高原季风的问题。

In this paper,the influences of land-sea and topography distributions on temperature anomalies from latitudinal means are studied. The results are obtained that the Eurasia continent and Tibetan Plateau located in the eastern half part of northern hemisphere are the most warmest in all hemispheres.The direct influences of land-sea and topography are different from the size of land-sea. The extent and intensity of temperature anomalies of the land-sea influence are the biggest and the strongest over ground surface,then decrese with height,thereafter reaching the 2 nd maximum value at 200-300 mb.The above phenomena may be caused by sensible heat from ground surface and by latent heat of precipitation and sublimation.The role of the Tibetan Plateau strengthens the effect of the land-sea distribution.The effect of large-scale orography is far larger than its actual extent of topography.In addition, the problem of Plateau monsoon is discussed, too.
