摘 要: 西南区域地形地貌复杂,站网分布不均匀,针对复杂地形下气象网格实况分析产品快速检验的需求,提出了质量评估数据预处理分段计算思路和缓存加速优化方法,设计了系统的数据流程,并优化了高分辨率格点场显示技术和检验评估产品检索技术。测试成果表明,预处理分段计算方案较传统的指标完整实时计算方案的运行耗时有10倍及以上的提升,能够满足用户实时交互的要求,并且通过平台实现了复杂地形不同坡度、坡向场景下评估指标的实时显示、任意时段分析评估和站点格点对比分析等功能,为气象实况分析产品的示范性应用和实时检验评估提供了系统支撑。

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.
