摘要

记录了香港夏季连续两天在香港国际机场出现的沙尘暴。它们与海风辐合线有关，是反气旋的。记录了沙尘暴发生的背景气象条件。研究了海风辐合线处微小反气旋流动的计算机模拟。本文讨论了在复杂地形地区进行海风环流微尺度模拟的难点和成功再现沙尘暴气流旋转感的问题。希望本文能对文献中有关尘卷风的研究提供有益的参考。

Observation and numerical simulation of dust devils at the Hong Kong International Airport in sea breeze situation

Dust devils at Hong Kong International Airport in two consecutive days in the summer of Hong Kong are documented. They are found to be related to the sea breeze convergence lines and are anticyclonic. The background meteorological conditions under which the dust devils occur are documented. The computer simulation of the tiny anticyclonic flow at the sea breeze convergence line is studied. This paper discusses the difficulties in the micro-scale simulation of the sea breeze circulation in an area of complex terrain and the successful reproduction of the sense of rotation of the dust devil flow. It is hoped that the paper could be a useful reference for the studies of dust devils in the literature.
