摘　　要：本文以美国国家大气研究中心(NCAR)气象再分析数据(Reanalysis data)和美国地质调查局(USGS)地理数据为基础,采用MM5/CALMET耦合模拟新疆五彩湾矿区四季的风速矢量场、温度场以及混合层高度。结果表明:春季的平均风速最大,为3.90m/s;风向全年以北西向及东南风为主。冬季与夏季相比,逆温层厚度较大、维持时间较长,夏季混合层高度较高;而冬季辐射能力较弱,混合层高度最大只有200m。矿区四季温差较大,夏季和冬季最高温和最低温最大相差37℃,并且昼夜温差在10℃以上。In this paper, based on the Meteorological reanalysis data of NCAR and geographic data Of USGS, then use MM5 and CALMET for atmospheric conditions simulation of the study areas. It＇s found by simulation that the wind is the fastest in spring for 3.9m/s. The main wind is northwest and southeast wind. Compares with the summer, the inversion layer of the winter is very thick. In summer, the mixing height is high, but in winter is only 200 meters high. A wide temperature differential of the seasons, the highest mean temperature of summer is about 37 ℃ higher than the lowest temperature in winter, and the temperature difference between day and night is above 10℃.
