Primary Discussion on the Characteristics and Forecasting Methods of Dense Fog in Xuzhou City
摘要
Abstract
[Objective] The study aimed to discuss the characteristics and forecasting methods of dense fog in Xuzhou City. [ Method] Based on the data of dense fog in Xizhou City during 1960 - 2009, the characteristics and forming conditions of dense fog in the region were analyzed , and then its forecasting methods were introduced, finally corresponding disaster prevention measures were put forward. [ Result ] Dense fog might appear in each season, its frequency of occurrence was the highest in December, namely 16. 4% ; it was the lowest in June (2. 2% ), and the fog lasted for a short time and was thin. Heavy fog occurred more frequently in winter half year than summer half year, and "the frequency of occurrence from October to next February was about 66. 7%. In addition, dense fog mostly generated from late midnight to morning, while it appeared less in the afternoon. It shows that dense fog in Xizhou City is mainly radiation fog instead of advection fog, but the two kinds of fog appeared simultaneously sometimes. [Conclusion] The research could provide scientific forecasting methods for the precise prediction of dense fog in Xizhou City.关键词
