2005年夏季海气热通量影响副热带高压数值试验

A Numerical Study on the Impact of Summer Air-Sea Heat Fluxes on Subtropical High in 2005

利用RegCM3区域气候模式对2005年夏季西北太平洋副热带高压进行了控制性和敏感性试验,试图探讨海气热通量异常对西北太平洋副热带高压移动、强度的影响。结果表明:感热、潜热通量的变化对低层的西北太平洋副热带高压北跳并不起决定性作用,但对副高主体的强度、东西移动有显著影响。

Using a region climate model RegCM3, a control experiment and sensitive experiments are run to simulate the impact of summer air-sea heat fluxes on subtropical high in 2005. It is shown that sensitive heat flux and latent heat flux aren＇ t the main factor which domain the northward movement of the ridge line of West Pacific Subtropical High. However, there＇s a remarkable impact on the intensity and the westward movement of WPSH.
