Analysis of Land Surface Energy Changes at Zhufeng Station in Qinghai Tibet Plateau in 2008

Abstract

The surface radiation balance and partial meteorological elements in the Qomolangma region were analyzed by using the flux observation data of Qomolangma stations in 2008 in the High-Resolution Integrated Observation Dataset of Earth-Atmosphere Interaction Process of the National Tibetan Plateau Scientific Data Center. The main conclusions are as follows: 1) The influence of weather conditions on the total solar radiation is more significant at high altitudes. For 2008, radiation on average each component change after comparative analysis, not only from atmospheric radiation, upward curve comparison verified the surface temperature in the plateau area affected by the solar total radiation that largest at the same time from the curve of the downward shortwave radiation found in contrast, although the Everest region influenced by latitude and longitude and altitude. However, the maximum value of short- wave downward solar radiation at noon appears in spring and April, and the maximum value of summer radiation at noon is even lower than that in autumn. 2) In the analysis of the typical weather conditions of continuous sunny days and continuous rainstorm, it is found that the net radiation and the Upward short-wave radiation are affected by the underlying surface change, and the amplitude of the net radiation and Upward short-wave radiation are close to the original atmosphere because the atmospheric environment in the Qomolangma region is close to the original atmosphere, so the net radiation and Upward short-wave radiation are affected by the underlying surface change under any weather conditions. 3) Surface water content has obvious influence on radiation and reflectivity by changing the properties of underlying surface, and the response energy changes the fastest when the upward shortwave radiation has higher humidity.
