Analysis on Distribution Pattern of High Wind Events in Qiongzhou Strait Coastal Zones and Its Weather Systems
摘要
Abstract
Based on the data from automatic weather stations in the Qiongzhou Strait northern and southern coasts,the distribution patterns of high wind events in both coastal zones were analyzed.And the difference between them was also analyzed using weather systems.The high wind events are defined into two kinds：sustained winds and gust winds.The results are as follows：In southern coast,the high wind events are more frequent than in northern coast,but the speeds of gust winds are obviously bigger in northern coast than in southern coast.The high wind events in northern coastal zones and the sustained wind events in southern coastal zones mainly happen in autumn and winter but rare in other seasons,and the sustained wind events in both coastal zones mainly occurred by cold air.But the gust wind events in the southern coastal are quite special,which mainly happen in autumn and rarely occurred by cold air.In both coastal zones of the Qiongzhou Strait,the high wind events happen with more frequency and bigger speed on the east entrance than on the west entrance,and with the least in the middle of coastal zones.There exist pronounced phenomena that the northeast high wind was donsinant in both coasts of the strait.The high wind events are more easily occurred by cold air from east than from west.The Qiongzhou Strait can obviously make the turbulent intensity of cold air turning weak.关键词
