| 摘 要： | 利用中尺度数值模式WRFV3.1.1中的MYJ、QNSE、YSU、ACM2、MYNN2.5、MYNN3、Boulac七种不同边界层参数化方案,进行了发生在长江下游地区的3例暴雨的模拟试验.重点分析比较了七个不同边界层参数化方案对降水总量分布、次降水区的边界层结构、关键基本气象要素场的模拟能力,并将降水总量和关键基本气象要素场的模拟结果与实测结果进行了统计检验.通过对比,发现QNSE方案的模拟能力相对优于其他边界层参数化方案.

| Abstract: | By using several planetary boundary layer schemes (Mellor-Yamada-Janjic; quasi-normal scale elimination; Yonsei University; asymmetric convective, version 2; Bougeault-Lacarrere (Boulac); Mellor-Yamada-Nakanishi- Niino, level 2.5; and Mellor-Yamada-Nakanishi-Niino, level 3) in a Weather Research and Forecasting (WRF) numerical model, seven sets of model simulations for three rainstorm cases in the lower reaches of the Yangtze River were performed. This paper thoroughly analyzes and compares the simulation ability of seven planetary boundary layer parameterizations with respect to the distribution of 24-hour total rainfall, boundary layer structure in the rainstorm area, fundamental fields of meteorological elements, and statistical test results for total rainfall. A comparison of the simulations and the observations indicated that the quasi-normal scale elimination planetary boundary layer scheme is superior to the other six. |
