Occluded Front
What type of weather does an occluded front bring?
Precipitation
What type of weather is associated with a stationary front?
Cloudy skies and light rain
What type of weather is associated with a cold front?
Temperatures cool and storms are possible
What type of weather is associated with warm fronts?
Rain and snow is possible
What weather occurs in a high pressure system?
How do occluded fronts differ from other types of fronts?
They form when two different fronts run into each other, not when two different air masses run into each other
When the boundary between two air masses stall, is when it forms
How does a cold front form?
They form as a cold air mass moves toward a warmer air mass causing the cold air to push under the warm air.
How does a warm front form?
When a warm air mass moves toward a cold air mass causing the warm air to rise over the top of the cold air mass.
What weather occurs in a low pressure system?
How do occluded fronts form?
When a fast moving cold front catches up with a slow moving warm front, is when an occluded front forms
How long can a stationary front stick around for?
A few days
How are cold fronts represented on a forecast map?
A blue curve with triangles pointing outward
How are warm fronts represented on a forecast map?
A red curve with semi circles pointing outward.
In a high pressure system, what happens to the dense air?
It sinks and clouds cannot form
How are occluded fronts represented on a forecast map?
A spiral with one line as a cold front and the other a warm front. Then the top is purple with a mix of triangles and semi circles.
How is a stationary front represented on a forecast map?
Almost an s shaped line with a mix of triangles and semi circles pointing outwards.
In a low pressure system, what happens to the warm air?
It rises and then cools causing the water vapor in the air to condense.
