The vapour condenses and falls from the sky. The state it reaches the Earth's surface in depends on a number of different f ...

Heat transfer from a hot body to a cold body can spontaneously occur. However, heat transfer in the reversed direction can not happen without the ...

ESCI 107/109 – The Atmosphere Lesson 9 – Wind Reading
... Wind is caused by pressure differences in the atmosphere, which set the air in motion. The forces that act on the air are ο Pressure Gradient Force (PGF) – This is the force caused by the difference in air pressure on opposite sides of the air parcel. This force tries to push the parcel toward l ...

Atmospheric convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference, layer in the atmosphere. Different lapse rates within dry and moist air lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.
