Abstract:Some assessments and problems in the scientific and technological development of Chinese operational weather forecast have been discussed. From the view point of comparison between international main-stream development and Chinese current operational state in weather forecasting techniques, some demerits and merits existing in forecasting services at national and provincial levels are argued in details. Based on such necessary argument and assessment, three crucial issues are emphasized, i.e., the development of weather forecasting should be integrated with the advanced synoptical sounding techniques, and objective weather analysis should be coalescent with subjective analysis. Moreover, the numerical weather prediction is very necessarily combined with the development of statistical method, in order to deal with chaotic nature.
