Freezing Rain
Freezing Rain thankfully is very rare in the UK. Freezing rain occurs when warm air moves above cold air
normally at the end of the a cold spell. For freezing rain to occur a layer of warm air pushes over sub zero
air at the surface. Snow falling through this turns to rain and then falls through the sub zero air turning to
ice on contact with the ground or other cold objects.

Rain
There are three main types of Rain.
Frontal rain which occurs along frontal troughs associated with low pressure systems where warm less
dense air is forced upwards forcing water vapour to condense and fall as rain.
Orographic rain which is produced when clouds formed are from the topography of the landscape when
moist air is forced upwards forming condensation and rainfall as a result.
Convective rain due to convective clouds forming in unstable air. You can see this on warm days where
moisture rises eventually cooling and forming clouds and eventually rainfall. This is more common in the
east and South of the UK. Such showers can be fairly localized and won’t effect such a large area such as
frontal rain.
