季风，为什么夏天下雨冬天晴？

In summer, the sea wind carries wet air. 夏天，海风带着湿空气来。 The wet air rises and becomes rain. 湿空气升上去，就变成雨。 In winter, the wind blows from the land. 冬天，风从陆地上吹过来。 That dry wind carries no rain. 干风里不带一滴水。 So rain moves with the seasons. 所以雨也跟着季节搬家。 This moving wind is called a monsoon. 这种会搬家的风就叫季风。
