The Complete Book of 100,000 Reasons Why
lit. ten thousand reasons why
为什么冬天会很冷？
1、地球的倾斜轴导致冬季阳光照射角度较低，能量分布不均，使得北半球（或南半球）远离太阳，接收到的太阳辐射减少。
2、冬季大气环流模式变化，冷空气从极地流向中低纬度地区，导致气温下降。
3、冬季植物落叶，地面裸露，缺乏植被的保温作用，使得地表热量更容易散失。
4、冬季海洋与陆地的温差增大，海洋冷却较慢，但陆地迅速降温，导致陆地气温更低。
5、冬季云量较少，白天吸收的太阳辐射减少，夜晚缺乏云层保温，热量散失更快。
总之，冬天冷是因为地球倾斜轴导致阳光照射角度低、冷空气流动、植被减少、海陆温差增大以及云量少等多重因素共同作用的结果。
