Day 6 - Fronts/Weather Map
by: harper mcdonald and piper stilwell
cold fronts
A cold front is the boundary of a progressing mass of cold air, particularly the trailing edge of the warm sector of a low-pressure system. They form when a cooler air mass moves into an area of warmer air, usually producing precipitation. They are represented by blue spikes.
warm fronts
A warm front is the boundary of a progressing mass of warm air, particularly the leading edge of the warm sector of a low-pressure system. They form by replacing a cooler air mass. They are represented by red domes.
stationary fronts
A stationary front is a pair of air masses, neither of which are strong enough to replace the other. They form when warm and cold air meet and neither air mass has the force to move the other. They are represented by an inter-playing series of blue spikes facing one direction and red domes facing the other.
occluded front
An occluded front is when a cold front overtakes a warm front and the cold front rotated around a storm and catches the warm front. They form when a cold front follows right behind a warm front and the warm air mass pushes into a colder air mass. Then, another cold air mass pushes into the warm air mass.They are represented by purple alternating triangles and circles facing the same direction.
