What is condensation?
Process by which water vapour in the atmosphere is changed into a liquid or if temps below 0 then a soild
What are the four reasons for condensation?
-radiation
-advection
-orthographic
-convective
What is radiation?
Occurs on calm, clear evening. Ground loses heat through terrestrial radiation and the air in contact with it is then cooled by conduction
What is advection?
Occurs from warm moist air moving over a cooler land/sea surface
What is orographic?
Warm moist air forced to rise
What is convective?
Air warmed during day and rises in pockets as thermals. As air expands, it uses energy and so loses hear and the temp drops
