答案
Front A front is a weather system that is the boundary separating two different types of air. / One type of air is usually denser than the other, / with different temperatures and different levels of humidity. / This clashing of air types causes weather: rain, snow, cold days, hot days, and windy days. / Two major types of fronts are cold fronts and warm fronts. / Normally cold fronts come with thunderstorms or other types of extreme weather. / They usually move from west to east. / Strong, powerful cold fronts often take over warm air that might be nearly motionless in the atmosphere. / This movement is called a low-pressure system, / which often causes severe rainfall or thunderstorms. / Warm fronts usually show up on the tail end of rain, snow, hail and fog. / As they overtake cold air masses, / warm fronts move slowly, usually from north to south. / Warm fronts are often associated with high-pressure systems, / which usually indicate calm, clear weather. /
解析
锋
锋属于一种天气系统,它指的是分隔两种不同类型空气的分界线。锋的两种主要类型为冷锋和暖锋。冷锋的到来常伴有雷雨或其他类型的极端天气。冷锋通常由西往东移动。强劲的冷锋往往会取代大气中那些几乎呈静止状态的暖空气。这一活动过程被称为低气压系统。暖锋通常出现在雨雪雾雹等天气的末尾。在暖锋压倒冷空气团的过程中,暖锋通常由北至南缓慢移动。暖锋经常和高气压系统联系在一起。
