    Shouldn’t air be warm in the inversion layer and cold air in atmospheric layers since temperature increases with height only in the inversion layer?

      Same doubt

      Actually what happens is that warmer air always rises up the cooler air. Think in thay way and you will get your doubt cleared

    Sir, please guide me that if there is a decrease in temperature with height then it is considered as standard atmosphere.
    Then inverse should be opposite i.e here temperature should increase with height.
    And finally we get a layer of warm air being trapped between layers of cool air.
    The above is my view point, which differs from yours. Please help.
