中文摘要: 锋面问题是气象学的古老课题之一,但从70年代以来,随着探测技术和计算技术的发展,这方面的研究又重新活跃起来,取得了若干进展,发现了一些新的事实并进行了一些较为成功的数值模拟。本文从锋面雨带的中尺度结构、锋生现象、锋区垂直环流、锋面向上的β中尺度系统、锋面的动力学问题和地形对锋面的影响等方面,简要地介绍了锋面研究近几年所取得的进展,指出动向,并结合实际情况提出了我国今后进行锋面分析和预报工作时应注意的问题。

Abstract:Great advances have been made in frontal research since 1970s. Mesoscale structure-of frontal rainbands was revealed by Doppler radar. Frontogenetical theory was deve. loped and evolution of meso-BBB system on front was successfully simulated by numerical model.Nevertheless, future observational, diagnostic and theoretical investigation is still ceded. Relation between front and upper level jet streaks as well as interaction between cross,-front circulation and mesoscale convective system on the front should be-clarified. Meanwhile, various mesoscale dynamical instabilities including conditional. symmetrical instability should be inquired further.Finally, some suggestions about research of the fronts in China are made.
