摘要
为了研究卫星资料对中尺度客观分析的影响,本文应用逐步订正方法,分别对500hPa和700hPa高度场作客观分析,共作了三个试验:只用常规资料;只用卫星资料;将常规资料和卫星资料相结合。客观分析表明:常规资料分析结果和人工分析的天气图最为接近。加进卫星资料能分析出一些只在卫星云图上有所反映的小扰动,说明卫星资料对中尺度客观分析有作用。
The successive correction method (SCM) of Cressman is adopted in objective analysis for 500 hPa and 700hPa height field,using the conventional data,or satellite data,or conventional data accompanied by satellite data. It shows that the analysis field using the conventional data is very similar to the real weather map,while the satellite data can reveal some small disturbances which can not be found in weather map but in satellite image,it indicates that the satellite data has the positive impact onto the meso-scale objective analysis.
