What is the meaning of atmospheric circulation?
Atmospheric circulation is the large-scale movement of air, and the means by which thermal energy is distributed on the surface of the Earth. The circulation of wind in the atmosphere is driven by the rotation of the earth and the incoming energy from the sun.
What is the atmospheric circulation model?
The global atmospheric circulation model is a simplified version of how air currents in the atmosphere move. It is used to help explain weather patterns and climatic regions. The global atmospheric circulation model is based around cells. These cells are regions where the air moves from low pressure to high pressure.
What is global atmospheric circulation definition geography?
The global circulation can be described as the world-wide system of winds by which the necessary transport of heat from tropical to polar latitudes is accomplished. In each hemisphere there are three cells (Hadley cell, Ferrel cell and Polar cell) in which air circulates through the entire depth of the troposphere.
What is the importance of atmospheric circulation to the redistribution of heat?
Because air currents and ocean currents work together to redistribute heat, the general circulation of the atmosphere is closely related to the general circulation of the ocean. Winds blowing over the sea surface produce ocean currents. Winds also evaporate water, which precipitates elsewhere as rain.
What is the general circulation of the atmosphere?
Atmospheric circulation, any atmospheric flow used to refer to the general circulation of the Earth and regional movements of air around areas of high and low pressure. On average, this circulation corresponds to large-scale wind systems arranged in several east–west belts that encircle the Earth.
How to teach the global atmospheric circulation model?
A recurring theme within the #geographyteacher community on Twitter is about how to teach the global atmospheric circulation model. The model seems to strike fear into the hearts of teacher, and students, alike. I confess, I felt exactly the same the first time I taught it.
Which is the driving force of atmospheric circulation?
Atmospheric circulation is the movement of air at all levels of the atmosphere over all parts of the planet. The driving force behind atmospheric circulation is solar energy, which heats the atmosphere with different intensities at the equator, the middle latitudes, and the poles.
How is the circulation of air related to precipitation?
Long-term mean precipitation by month. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth’s atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly
