Question

Where do you expect the pressure to be high at the equator or at the poles why

Answer 1

Hola there The amount of heat radiation is of maximum at the equator. The cold air at the poles is denser than the warm air at the equator; hence, air pressure at sea level is higher at the poles than at the equator. In other words, the pressure gradient at sea level is directed from the poles toward the equator, and the pressure gradient in the upper part of the atmosphere has the opposite sign.
In fluid and gases pressure gradients produce flow from regions of high pressure to regions of low pressure. If the earth were not rotating, the response to these pressure gradients would be direct and simple.
