Construction Of Severe Convective Vertical Profile Sequence And Research Of Three-dimensional Visualization

In the meteorological field ,with the sustainable development of weather radar technology, the weather radar data become more and more rich, amounts of data become more and more large, it is more difficult directly for the people to understand these data visually ,in addition, severe convective and other disastrous weather have huge threat on people's normal production and life. Therefore, it becomes very necessary to develop an assistant tool to make weather forecasters more intuitive and better understanding the atmospheric state which is reflected by a large number of meteorological data . the accuracy of severe convective weather forecast will be improved and the losses caused by disasters will be reduced with the help of the tool,.The 3-D display system of Radar vertical profiles sequence in this paper is developed by VC6.0 and some research work do as follows:1 We structure the radar vertical profiles by any cutting liner in reflectivity images.2 As coordinates of region and optimal cutting line is given, we structure the Radar vertical profiles sequence by calculating all the cutting lines in the region.3 We built three-dimensional stereo model with each profiles based on the construction of radar vertical profile sequence by OpenGL texture mapping,4 We develop a three-dimensional dynamic display system ,which has Human–Machine Interaction function such as scaling ,rotating ,movement. The system can help weather forecasters all-round, multi-angle analysis and understand three-dimensional images, and then improve the accuracy of weather forecasts.In this dissertation, the research work develop a new assistant tool for weather forecast and has been applied in some areas, it has achieved the expected results and made important contributions for the weather forecast.
