摘要:
利用1959-2013年四会当地的气象资料,分析了四会雾的气候特征。结果表明:(1)四会年平均雾日数总体呈现增加趋势,雾日数总体呈现为春季 > 冬季 > 秋季 > 夏季的特征;四会雾多出现在夜间及早晨,白天随着太阳辐射的增强,雾逐渐消散;适宜的风速(1-2级)和较高的相对湿度有利于雾的形成和维持,雾日大多伴随降水。(2)四会雾主要有两种:辐射雾和平流雾,辐射雾发生时四会受冷高压控制;而平流雾发生时,广东以北存在地面冷高压中心,并伴有弱冷空气持续渗入四会。
Abstract:
Based on the meteorological data of Sihui from 1959 to 2013, the characteristics of fog were analyzed. The results show that:(1) the annual average fog days showed a trend of increase in overall, the general feature of fog days presents spring > winter > autumn > summer; fog mainly appeared in the night and morning, with the augmentation of the solar radiation during the day, the fog dissipates gradually; Suitable wind speed (1-2) and relatively high humidity are advantageous to the formation and maintenance of fog, fog day mostly associated with precipitation. (2) there are two main types of fog in Sihui:radiation fog and advection fog, and the radiation fog occurs under high pressure control, while the advection fog appears when surface cold high pressure center affecting north of Guangdong with weak cold air infiltrating Sihui.
