2010年陕西主要气象灾害及灾情年景评估

针对侯马市气象局地面测报工作任务越来越多,工作质量要求不断提高,人工计算已不能满足需求。因此从实际工作出发,基于VB（Visual Basic）6．0平台,开发了侯马市地面测报质量基数计算程序。该程序可计算值班人员当月的各类工作基数,并将结果直接输出成Excel电子表格,用以数据的保存、统计分析与打印。     

Numerical resolution of well-balanced shallow water equations with complex source terms

This paper presents a well-balanced numerical scheme for simulating frictional shallow flows over complex domains involving wetting and drying. The proposed scheme solves, in a finite volume Godunov-type framework, a set of pre-balanced shallow water equations derived by considering pressure balancing. Non-negative reconstruction of Riemann states and compatible discretization of slope source term produce stable and well-balanced solutions to shallow flow hydrodynamics over complex topography. The friction source term is discretized using a splitting implicit scheme. Limiting value of the friction force is derived to ensure stability. This new numerical scheme is validated against four theoretical benchmark tests and then applied to reproduce a laboratory dam break over a domain with irregular bed profile.
