摘　　要：为了研究边界层参数化方案对文昌近地层风速模拟的影响,本文选用美国国家环境中心终分析资料FNL (Final Operational Global Analysis)作为模式的背景场资料,应用WRFV4.2.1模式10种边界层参数化方案(YSU, MYJ, QNSE, MYNN2, MYNN3, BouLac, UW, TEMF, Shin-Hong和GBM),对文昌近地层2015年每月前三天的风速进行数值模拟,检验评估了它们对不同高度层风速的预报能力。结果表明:MYNN2方案和MYNN3方案在低层的风速模拟效果较好,UW方案、GBM方案和BouLac方案在高层风速模拟效果较好,TEMF方案风速模拟效果最差,且总体来看10个方案在70 m和90 m高度层的风速模拟效果更好。In order to study the influence of boundary layer parameterization scheme on the wind speed simulation of Wenchang near-surface layer, this paper selects the Final Operational Global Analysis (FNL) data of the National Environmental Center of the United States as the background field data of the model, and uses 10 boundary layer parameterization schemes of WRFV4.2.1 model (YSU, MYJ, QNSE, MYNN2, MYNN3, BouLac, UW, TEMF, Shin-Hong and GBM) to numerically simulate the wind speed of Wenchang near-surface layer in the first three days of each month in 2015. Their ability to forecast wind speeds at different altitudes was tested and evaluated. The results show that the MYNN2 scheme and MYNN3 scheme have better wind speed simulation effect at the low level, the UW scheme, GBM scheme and BouLac scheme have better wind speed simulation effect at the high level, and the TEMF scheme has the worst wind speed simulation effect. In general, the wind speed simulation effect of the 10 schemes at 70 m and 90 m levels is better.
