Cold Front
Warm Front
Stationary Front
Occluded Front
cold air mass pushes under warm air
mass. Storms may come at the
beginning but leave clear dry weather
after.
warm air mass pushes into and over a
cold air mass. Storms / rain may occur
after the front for a period of days.
warm air mass pushes into cold air
mass but neither mass is strong
enough to push over the other causing
rain to last for several days.
one air mass type is pushed between
two other air masses causing a variety
of weather systems ranging from
violent to dry and clear afterwards
Convection
Jet Stream
Prevailing Westerlies
Polar Easterlies
process that occurs when increased
temperature causes substances to rise
(less dense) and the cooler
temperature causes substance to sink
(more dense)
fast moving belts of winds high in the
atmosphere
Winds that move from the West to the
East
Winds that move from the poles down
ward from East to west.
doldrums
area around the equator where the
winds are very calm
horse
latitudes
30 degrees above and below equator
where the winds rarely blow - ships
would get stuck here due to low winds
El Niño
In Pacific ocean warm water phase,
weak trade winds
Moves West to East
La Niña
In Pacific ocean cool water phase,
strong trade winds, causes storms
Moves East to West
Coriolis Effect
Radiant Energy
The deflection of winds and large
ocean currents moving towards the
poles and the equator due to the
rotation of the earth.
Solar energy is radiant energy from
Sun – warms without having to touch
air or water
Land Breeze
The breeze that occurs at night when
cool air from land moves out over
warm water.
Sea Breeze
The breeze that occurs during the day
when cool air from the water moves
out over warm land.
