Authors have developed the software of the personal computer system, which has the functions of correction of distortion (geometric, radiometric), projection (polar) and display (cross section, histogram), to serve the system to general VISSR image data analysis.
As some examples of application of the system, feature of typhoon and evaluation of convective cloud clasters were studied. The results are as follows:
-the lowest pressure of typhoon occurred after maximum extention of central dence overcast (TBB lower than -70°C);
-a feature of ratio of area occupied by every 5°C (TBB -40°C to -70°C) to the around typhoon center was changed after the direction of typhoon was suddenly turned northward;
-correspondence between the highest reflectivity and the minimum TBB core was mostly good in the mature stage of a convective cloud cluster, but in the developing stage of the core the correspondence was poor;
-the most ascending speed of a convective cloud top (325 m/minute) was observed in the developing stage.
These results indicate that the system is effective for meteorological phenomena analysis.
