引言珠海市三灶机场(以下用“机场”简称)位于广东省珠海市三灶半岛,北纬22度00分,东经113度22分。机场位于珠江口西侧岸,三面环海,一边靠山,是海洋陆地山脉的交汇过渡带,常常是海陆天气系统的交汇处。珠海夏季为西南季风的盛行期,西北太平洋和南海多热带气旋活动,是热带气旋影响或台风袭击的盛期。当热带气旋影响或登陆珠海或珠江口地区时,天气表现为长时间的狂风暴雨,雷暴等,对飞行活动影响很大。由于复杂的地理环境,夏季的珠海也是强对流天气、强降水集中等危险天气的最多发生季节(本文中所用时间无特殊说明的,均为UTC时间)。
Introduction Zhuhai Sanzao Airport (hereinafter referred to as “Airport”) is located in Zhuhai City, Guangdong Province, Sanzao Peninsula, latitude 22 degrees 00 minutes, longitude 113 degrees 22 minutes. Located on the west bank of the Pearl River Estuary, the airport is surrounded by the sea on three sides and is a backdrop for the convergence of marine terrestrial mountain ranges, often at the intersection of land and sea weather systems. The summer of Zhuhai is the prevalent period of the southwest monsoon, and the activities of the tropical cyclone in the northwest Pacific and the South China Sea are the peak of tropical cyclone impact or typhoon attack. When tropical cyclones affect or land in Zhuhai or the Pearl River estuary, the weather is characterized by prolonged stormy storms and thunderstorms, which have a great impact on flight activities. Due to the complex geographical environment, Zhuhai in summer is also the most frequently occurring season of dangerous weather such as strong convective weather and heavy precipitation concentration.
