| Abstract: China's southwest region has complex topography, and its station network is very unevenly distributed. In response to the demand for rapid inspection of meteorological grid real-time analysis products under complex terrain, this paper proposes an evaluation data preprocessing segmented calculation idea and a method of cache acceleration optimization, designs the system data flow, and optimizes the high-resolution grid field display technology and the retrieval technology of evaluating product. The test results show that the pre-processing segmental calculation scheme reduces the running time by 10 times or more, compared to that of the traditional indicator complete real-time computing scheme, which can meet the user's real-time interaction requirements. The platform can realize the real-time display of evaluation indicators under different slope and slope direction scenarios of complex terrain, analysis and evaluation at any time period, and comparative analysis function of station grid points. It provides system support for the demonstration application and real-time inspection and evaluation of meteorological live analysis products. |
