FRONTS:
FRONTS are the boundary betweentwo air masses.It always rains at the frontalboundaries.
Warm front brings warm air mass thatreplaces a cold.
cold front brings cold air mass thatreplaces a warm
stationary front: cold air mass upagainst a warm air mass.
stationary front: cold air mass upagainst a warm air mass.
occluded front: a warm air masstrapped between two cold.
Low pressuresystems versushigh pressuresystems:
Low pressure systems: winds flowcounter-clockwise and in. bad weather
high pressure systems: winds flowclockwise and out. good weather
