入侵我国的寒潮为什么大多来自西伯利亚？
Why do most cold waves hitting China come from Siberia?
西伯利亚是大陆腹地，冬天极度严寒、冷空气堆积成高气压，一旦气压失衡就向南爆发，席卷我国带来大风降温。
Siberia's continental interior gets brutally cold, piling up high-pressure air that bursts southward into China with wind and chill.

冰雹为什么多发生在暖季而不是寒冬？
Why does hail fall in warm seasons rather than deep winter?
冰雹需要强盛的上升气流把冰粒反复托起、层层裹冰，暖季对流最猛，高空又够冷，才结得出大冰雹。
Hail needs strong updrafts to toss ice grains up and coat them repeatedly; warm-season convection is fiercest while the upper air stays cold enough.

雾霾天和“静风”天气有什么关系？
What is the link between smog and calm, windless weather?
风小、逆温层像盖子一样压在头顶时，污染物散不出去，在城里越积越浓，就容易形成雾霾。
With little wind and a temperature inversion acting like a lid, pollutants can't disperse and build up into smog.

雷阵雨为什么常常在夏天午后“准时”出现？
Why do thunderstorms often strike right after summer afternoons?
午后地面被晒得最热，湿热空气猛烈上升，到高空遇冷凝结成积雨云，于是电闪雷鸣、暴雨倾盆。
Afternoon ground is hottest, so humid air rises violently, condenses into cumulonimbus aloft, triggering lightning and downpours.

北方冬天为什么会有“白毛风”这种天？
Why does northern winter bring white-haired wind storms?
那是强冷空气卷着地面积雪漫天飞舞，视线里白茫茫一片，又叫“风吹雪”，又冷又看不清路。
It is strong cold air whipping surface snow into the air—blowing snow—a whiteout that is freezing and blinding.
