The air above the poles is cold. The cold air sinks creating high pressure. The air moves towards the equatorial low-pressure zone, and warms up when it meets the land or ocean. At around 60 ...

This process maintains the global energy balance. Scientists have studied atmospheric circulation and have agreed on a simplified model to explain the redistribution of energy from areas of ...

The Hadley circulation, a fundamental component of Earth's atmospheric system ... zonal mean Hadley circulation intensity, climate model simulations predict a weakening trend.

Figure 1: Brewer–Dobson circulation and stratospheric ozone. No one would question the benefit of a full representation of the stratosphere in an atmospheric model. But given limited ...
