What are local winds dictated by, that is not part of the 3-Celled Global Winds Model?
How are these systems formed? What happens at these systems?
small-scale high and low pressure systems
A low pressure center is formed when air over land is heated more relative to the air around it. This causes the air to expand and rise. A high pressure center is formed when air over land is heated less relative to the air around it. This causes the air to get closer together and sink. Two low pressure and high pressure systems near each other essentially form a loop —→
What are small scale low and high pressure systems associated with respectively?
Low pressure systems are associated with storms, rain, clouds, etc. High pressure systems are associated with clear skies.
How do fluids (incl. air) move in regards to pressure?
They move from areas of high pressure to areas of low pressure, to balance out the pressures and reach equilibrium.
How do low pressure and high pressure systems rotate? Remember to do it for each hemisphere.
In the Northern Hemisphere, high-pressure systems rotate clockwise. Low-pressure systems rotate counterclockwise. This rotation is due to the Coriolis effect. It is the opposite in the Southern Hemisphere.
Coriolis Effect shifts direction to the ______ in the Northern Hemisphere and to the ______ in the Southern Hemisphere.
right, left
Helps with seeing how a small scale pressure system will rotate — ex. with a high pressure center pciture one line going out forward to low pressure, this bends to right in Northern Hemi so clearly clockwise. for a low pressure center in Northern Hemi it will be opposite so counterclockwise.
What pressure center is a hurricane or storm in general?
Low pressure, air moves into it.
