本书解释了天气是如何运作的。

为什么会下雨？雾从哪里来？雷雨中会发生什么？地理环境是如何影响天气的？本书富有有趣的事实、琐事和轶事，例如，厄尔尼诺现象的名字从何而来、如何通过蟋蟀的鸣叫来判断温度。

本书解答了很多问题，例如如何预测天气、科学家使用的是什么仪器；展示了气象站；发现了沙尘暴、飓风、雷暴雨的风；解释了云和云层，以及世界尽头的冰原。

Whatever the Weather explains how the weather works.

Why is it raining? Where does the fog come from? What happens in a thunderstorm? How does geography affect the weather? Whatever the Weather features fun facts, trivia, and anecdotes, e.g. where did El Niño get its name from or how you can tell the temperature by a cricket's chirp.

Whatever the Weather covers questions like how does forecasting work or what instruments scientists use. It shows a weather station and discovers wind from sand storms, hurricanes to thunderstorms to explaining clouds and cloud formations, to the ice sheets at the ends of the world.
