How is air pressure created
Web24 nov. 2024 · In general terms, cloud is formed when moist air is cooled down to its dewpoint. The main methods of cooling are through conduction (touching the cold ground or ocean) or through adiabatic cooling via convection (when the air rises and expands). High pressure areas means the air is sinking from above.
