What process causes latent heat to be released into the upper troposphere?

  • A

    Evaporation over widespread water areas.

  • B

    Descending air across widespread areas.

  • C

    Stabilisation of inflowing air masses.

  • D

    Cloud forming due to condensation.

Latent heat is the energy released or absorbed by a substance during a phase change, without a change in temperature.

When moist air rises through the atmosphere, it cools and reaches its dew point, leading to the condensation of water vapor into tiny droplets that form clouds. This process, known as condensation, releases latent heat back into the surrounding air, warming it. This release of latent heat is a key source of energy in weather systems, including tropical cyclones and polar lows.
