摘　　要：文章基于1957—2010年呼和浩特气象站、1982—2010年索伦气象站的高空温度资料,利用MannKendall检验法和累积距平法对高空温度资料进行了突变分析。结果表明：呼和浩特气象站地面至700hPa层突变增温,200-150hPa无突变,索伦气象站地面至300hPa层突变增温现象,200-150hPa突变降温不明显,两站其他层次均有突变,且为降温趋势。Based on the high altitude temperature data of Hohhot weather station from 1957—2010 years and Suolun weather station from 1982—2010 years, this article made a mutation analysis on high altitude data. The results showed that Hohhot weather station appeared mutation warming phenomenon from ground to 700 hPa, there are not mutation phenomenon from 200 to 150 hPa. Suolun weather station appeared mutation warming phenomenon from ground to 300 hPa, there was not obvious mutation phenomenon from200 to 150 hPa, other high layer of two weather stations had mutation phenomenon without exception, and had decrease phenomenon moreover.
