【摘要】 本文在利用一个一层数值诊断模式进行天气研究试验的基础上,提出合理确定地形影响层高度H和大气不均一性加热,会改善中尺度数值模拟结果。特别指出H在模式中敏感性较大,通过试验与大别山实测资料的比较,可给出一个最佳的地形影响层高度H,以供理论研究和模拟试验参考。更多还原

【Abstract】 In this paper, the reasonable determination of the height(H) of topographic influence layer and the atmospheric nonuniform heating are provided, in order to improve the results of mesoscale numerical weather simulation, based on the experiments of one level numerical diagnostic model.It is noted that the height(H) is a very sensitive parameter in this model. A optimum value of H is got through a comparison of simulated value with observation of Dabie Mountain, for the reference of theoretic research and numerical simulation.更多还原
