【摘要】 <正> 号称“世界屋脊”的青藏高原,伸展到对流层的中部,对大气环流和东亚气候的显著影响,早已引起国内外学者的重视。叶笃正、罗四维、朱抱真计算过青藏高原对流层大气的热量平衡。叶笃正、张捷迁进行了青藏高原加热作用对夏季东亚大气环流影响的初步模拟实验。青藏高原低值系统协作组在研究盛夏高原低涡发生发展时也很重视高原的加热作用。更多还原

【Abstract】 Based on the data observed in Qinghai-Xizang Plateau we have analyzed the time-space distribution regularity of the global radiation, albedo, effective radiation and radiation balance value. Analysis shows that the global radiation and radiation balance in Qinghai-Xizang Plateau is the highest in China, their annual total values being 190Kcal/cm2 and 80Kcal/cm2,respectively. Their highest value is in the southwestern part of Qinghai-Xizang plateau. The zero isorithm of the annual radiation balance distributed along the northern foot of Kunlun Shan and Altun Shan. Therefore, with the exception of ice-snow zone,the annual values of radiation balance in most parts of Qinghai-Xizang Plateau are positive. Secondly, the relationship between global radiation and melt depth of permafrost has been established.更多还原
