海面热作用对台风发展的数值研究

Numerical analysis of the influence of heat fluxes from the ocean on the development of typhoon

本文在Hoskins关于斜压涡旋研究的基础上,研究了来自洋面热量通量对台风的影响。本文着重讨论了不同加热区域以及有、无热量通量的输送对台风扰动场型态和强度的影响。我们发现,海面加热作用不仅对台风扰动场的强度有显著的影响,而且对其型态也有明显的作用;加热范围的空间差异是决定扰动场分布型态差异的关键因子,而不是由加热场本身所能决定的。

Based on the study of Hoskins about baroclinic vortex, we study the influence of heat fluxes from the ocean on typhoon. The paper aims at discussing the effect of heated areas, the conditions with and without heat fluxes on the disturbed pattern and strength of typhoon. we find that heating plays a key role not only in strength but also in pattern of typhoon's disturbed field. The spatial difference of heating is decisive of the difference of disturbed pattern, but not heating itself.
