Abstract

According to the analysis to the climatic data of Xiao Tang in desert, Lun Tai in oasis during 1992 to 1997, the following viewpoints were noted: (1)The air temperature of desert is lower than the one of oasis in winter, the air temperature rise gradually from oasis to desert in summer. The diurnal range and annual range of air temperature in desert is wide than the one in oasis. (2)The precipitation of oasis is more than the precipitation of desert. The difference of seasonal precipitation is great in desert, the most of precipitation is in warm period, it is basic characteristics that mean-square diviations of precipitation are big in desert. Not only large-scale weather system affects the precipitation in desert, but also violent local thermal circulation can form the local unstable precipitation in desert. (3)The Humidity of desert is lower than humidity of oasis and the evaporation amount of desert is bigger than evaporation amount of oasis. The evaporation capableness of desert is mighty, the difference of seasonal evaporation amount is great in desert and the 77% of annual mean evaporation amount is in summer and spring.(4)The days of sand blown by wind weather in desert are more than the one of oasis. The wind speed in desert is faster than the one of oasis. These indicate that the difference is apparent between desert and oasis. This is caused by differences of Landscape and water amount. The exploitation and utilization on oasis enlarge this difference.
