资兴市东江湖旅游景区“雾漫小东江”成因分析

Analysis of the Cause of “Foggy Little Dongjiang River” in the East Lake Scenic Spot of Zixing City

应用东江湖景区现场监测数据及实景观测资料,统计了“雾漫小东江”景区的起雾情况,并从气象要素、水温及地形方面分析了起雾成因。研究发现,5—10月是“雾漫小东江”景区最佳观赏期,在有雾期和无雾期,相关气象要素值存在明显的差异。影响“雾漫小东江”平流雾生消的主要因素为风向转变、风速变化、近地层逆温层、地形。

Based on the on-the-spot monitoring data and real observation data of Dongjiang Lake scenic spot, this paper makes statistics on the fogging situation of the“Foggy Little Dongjiang River”scenic spot, and analyzes the causes of fogging from the aspects of meteorological elements, water temperature and topography. It was found that from May to October is the best viewing period for the“Foggy Little Dongjiang River”scenic spot, and there was a significant difference in the values of relevant meteorological elements between the foggy period and the non foggy period. The main factors affecting the advection fog generation and dissipation of“Foggy Little Dongjiang River”were the change of wind direction, the change of wind speed, the inversion layer near the ground and the influence of topography.
