全球风带

解释太阳加热不均如何驱动大尺度大气环流：哈德莱环流（0-30°）、费雷尔环流（30-60°）和极地环流（60-90°）产生信风、西风带和极地东风带；描述地球自转引起的科里奥利效应如何使北半球的风向右偏转；解释高空急流是一种引导天气系统的高速风；将急流的波动和北极放大效应与持续极端天气联系起来。

Explain that unequal solar heating drives large-scale atmospheric circulation: Hadley cells (0-30°), Ferrel cells (30-60°), and polar cells (60-90°) produce the trade winds, westerlies, and polar easterlies; describe how the Coriolis effect from Earth's rotation deflects winds rightward in the Northern Hemisphere; explain the jet stream as a fast high-altitude wind that steers weather systems; connect jet stream waviness and Arctic amplification to prolonged extreme weather

{{name}}能解释为什么英国的潮湿天气通常来自西边吗？是哪种全球风带在引导天气系统，地球自转又如何促成了这一现象？

Can {{name}} explain why the UK tends to get wet weather arriving from the west — what global pattern of winds is steering weather systems, and how does Earth's rotation contribute to this?
