摘　　要：利用统计学方法,分析了AMDAR(Aircraft Meteorological Data Relay)资料的时空分布特征,并将航站上的AMDAR资料与常规探空资料进行了对比。研究表明:AMDAR资料是一种高时空密度的观测资料,航站上的AMDAR资料的质量接近探空资料,但其时间密度大约是探空资料的10倍。因此,可以用来监测航站及附近地区天气系统及其演变的更细微的特征,为短时特别是临近预报提供更多的参考依据。The statistical method is used to analyze the spatial-temporal distributions of AMDAR （Aircraft Meteorological Data Relay） data. The AMDAR data are also compared with the conventional radiosonde data. The results show that the AMDAR data is one kind of observation with high spatial-temporal density; the quality of the AMDAR data is close to the radiosonde data; and the temporal density of the AMI）AR data is nearly ten times of that of the radiosonde data. Therefore, the AMDAR data can be used to monitor weather systems and the fine characteristics of their evolution around the airports, to provide more usefull references for short-time forecast, especially for nowcasting.
