The Geostrophic Wind
|
|
The atmosphere around the globe is a very thin layer. The globe has a diameter of 12,000 km. The troposphere, which extends to about 11 km (36,000 ft.) altitude, is where all of our weather, and the greenhouse effect occurs. On the picture you can see at stretch of islands 300 km (200 miles) across, and the approximate height of the troposphere. To look at it at a different scale: If the globe were a ball with a diameter of 1.2 metres (4 ft.), the atmosphere would only be 1 mm (1/25") thick. | |
