Generation of Three-Dimensional Meteorological Field based on Sounding Data

Given the uneven distribution of sounding and automatic weather stations throughout the Fujian province of China, a method for the extension of meteorological elements from point data to a three dimensional field is proposed, which can be used for hail detection and other weather forecasts. Considering the temperature and air pressure as the classic meteorological elements, these are extended to two and three dimensions and the error is analyzed according to the spatial distribution law of temperature and air pressure in the horizontal and vertical directions. The conclusions are that (1) the extension method of the meteorological elements to two and three dimensions proposed in this paper is characterized by high precision and reliability and (2) the generated height map for the same temperature level and vertical cross section of temperature can be very helpful for hail and other weather forecasts.
