Why does the temperature increase in the stratosphere?

Unlike the Troposphere the Stratosphere observes what meteorologists call temperature inversion, meaning the temperature increases with increase in altitude. read more

Because there is ozone layer in the stratosphere which absorb UV radiation from the sun, so by absorbing UV rays the ozone layer warms the air around it causes the temperature to increase. read more

The stratosphere is stratified in temperature, with warmer layers higher and cooler layers closer to the Earth. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet radiation by the ozone layer. read more
