It is above the troposphere.
The stratosphere begins about 10 kilometers (6 miles) above the Earth, or at an altitude of about 33,000 feet. Commercial aircraft travel in the lower stratosphere, where the air is thinner and aerodynamic drag is lower. Towering cumulonimbus clouds can reach into the stratosphere from the troposphere, and rarely high cirrus clouds (including condensation trails from aircraft). The stratosphere extends to about 50 kilometers (31 miles) above the surface. The stratosphere is closer at the polar latitudes, with the lower limit being about 8 kilometers (5 miles).
Yes, the upper stratosphere is colder than the lower stratosphere. This is because the stratosphere is heated from below by the Earth's surface, so as you move higher in the atmosphere, the temperature decreases. The temperature inversion between the lower and upper stratosphere is due to the absorption of solar radiation by ozone in the upper stratosphere.
No. The jet stream is in the upper troposphere and lower stratosphere.
The stratosphere is the layer above the troposphere (where we live). The ozone layer is found in the lower stratosphere. The stratosphere is the lowest layer where temperature increases with increasing altitude.
There is no rain in the stratosphere because the amount of water in the stratosphere is much lower than in the lower atmosphere, which means the condensation of water vapour which creates rain doesn't occur in the atmosphere.
