The science of atmospheric processes and phenomena
Troposphere is the lowest layer
Thin air is not as heavy as cooler air to the north and south of the equator
The earths surface gets very cold near the poles
PGF is caused by the difference between the weight of air above the pole and the weight of air above the equator
Creates a closed circuit in that cold polar air slides along the earths surface toward the equator and warm air from equator slides poleward aloft to replace it.
Since “weight” is caused by the earths pull acting on the mass of the air PGF is a manifestation of gravity
Rotation of the earth causes this simple circuit to change in two ways
Wind flows from the polar highs southward to the sub polar lows (60 degrees north) and is deflected to the west. These permanent winds are called the Polar Easterlies
