摘要： 为支撑北极航道区域数值预报系统构建, 以北极航道典型区域新奥尔松为对象, 采用Polar-WRF V4.1.1模式, 选取MYNN、MYJ、YSU、QNSE共4种边界层参数化方案, 针对冬夏季开展数值模拟。结合新奥尔松地面自动站观测与高空探测资料, 从近地面要素与大气垂直结构方面评估边界层方案适用性。结果表明: 4种方案的模拟效果存在显著季节性差异, 且近地面要素模拟差异大于垂直结构; MYNN方案冬夏季近地面要素模拟精度最优, 垂直结构模拟误差可控; YSU、QNSE方案仅部分要素模拟表现尚可, MYJ方案冬夏季整体误差最大。推荐采用MYNN方案作为该区域模式的边界层及近地层过程参数化方案, 研究结果为北极航道区域数值天气预报系统中边界层方案的选择提供科学依据。

Abstract:

To support the construction of a numerical weather prediction system for the Arctic shipping route, Ny-Ålesund, a typical region of the Arctic shipping route, was selected as the study area. Using the Polar-WRF V4.1.1 model, we conducted winter and summer numerical simulations with four planetary boundary layer parameterization schemes (MYNN, MYJ, YSU, QNSE). Based on surface automatic weather station observations and radiosonde data in Ny-Ålesund, the applicability of these schemes was evaluated in terms of near-surface meteorological elements and atmospheric vertical structure. The results show significant seasonal differences in simulation performance, with larger discrepancies in near-surface elements than in the vertical structure. The MYNN scheme achieved the highest accuracy in simulating near-surface elements in both seasons, with controllable errors in vertical structure simulation. The YSU and QNSE schemes performed adequately only for certain elements, while the MYJ scheme exhibited the largest overall errors. Thus, the MYNN scheme is recommended for planetary boundary layer and surface layer processes in this region, providing a scientific basis for selecting planetary boundary layer schemes in the Arctic shipping route numerical weather prediction system.
