The case experiment on objective analysis of meso-scale weather with satellite data

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.
