Climatic Characteristics of the Northern Hemisphere Snow Cover observed by Satellite and its influence on the Monsoon

摘要

Climatic characteristic and changes of snow cover over the Northern Hemisphere, Eurasian, North America and the Tibet Plateau are studied based on data of the Northern Hemisphere snow cover area observed by Satellite remote sensing from 1966 to 2003. Meanwhile,the seasons, distribution charts of the Asian snow cover are made, they provide the climatic background of snow cover. In addition, the influences of snow cover on the climate,especially on the monsoon are analysed briefly,and some significance results are concluded.
