一、引 言 众所周众,热带地区的数值天气预报远远落后于中纬度地区的数值天气预报。国际上的数值预报试验例如GAPP大西洋热带地区数值试验和首次GAPP全球数值试验,对于热带地区数值天气预报的进展具有很大的作用。这篇文章的主要目的是说明在热带地区,也就是在非洲的北部到东大西洋的区域上。应用宾夕法尼亚有限区域模式,成功地做出了5天中期天气预报。模式中所用GATE资料是由Princeton地球物理流体力学实验室提供的。预报结果将详细地用高空单站观测实况进行验证,包括模拟的流场和GFDL分析之间的比较。一些能量的计算表明了各种物理机制如何影响波状扰动的发展。
I. INTRODUCTION Everyone around the world, the tropical areas of the numerical weather forecast lags far behind the numerical weather forecast in the mid-latitude region. International numerical forecasting experiments such as the GAPP Atlantic Tropical Zone Numerical Experiment and the first GAPP Global Numerical Experiment play a significant role in the progress of numerical weather forecasting in the tropics. The main purpose of this article is to show that in the tropics, that is, in the north of Africa to the region of the East Atlantic. Using the Pennsylvania Limited Area model, a 5-day mid-term weather forecast was successfully made. The GATE data used in the model was provided by Princeton Geophysical Fluid Mechanics Laboratory. The forecast results will be validated in detail using high-altitude single-station observations, including a comparison between the simulated flow field and the GFDL analysis. Some energy calculations show how various physical mechanisms affect the development of wavy disturbances.
