A river of air called the jet stream runs along the troposphere just near the top. The troposphere starts at ground level and rises 11 km up which is equivalent to 7 miles or 36,000ft.
About 3/4 of the air in our atmosphere is in the troposphere and almost all weather happens here. Most of the clouds are found in the troposphere layer.
The jet stream is found just near the top of the troposphere zooming along at a speed of 400km/hr (250 miles per hour)
