摘要
根据1979年5—8月青藏高原热源观测资料,作者分析了高原上长波辐射随海拔高度的变化特点。地面辐射随海拔的的变化很缓慢,大气逆辐射随高度增高而很快减小,地面有效辐射在观测高度范围内(500米以下)则随着测点增高而增大。因此,如果将平原地区观测资料配合的计算有效辐射公式用于高原,其值将系统性偏低。为了表示平原与高原不同高度有效辐射的差别情况,作者根据观测资料求得了地面有效辐射与海拔高度的关系式。
Radiation observations from May to August 1979 in the Qinghai-Xizang Plateau, are used to describe the variation of terrestrial radiation with altitude. The decrease of the downward flux with increasing altitude is more rapid than the upward component, and consequently the effective radiation within the range of observing altitude (below 5000m) increases with the altitude of the radiative surface.Depending on the data of radiation observed at Nanjing, Golmud, Lasha, Shiquanhe and shuanghu, the formula for calculating the effective radiation on the surface at various altitude is obtained
