Question

How does uneven heating between the equator and the poles generate wind currents?

Answer 1

The regions close to equator get maximum heat from the sun. This makes the air warm which rises up arid the air from the regions in the 0-30 degrees latitude belt on either side of the equator moves in. These winds blow from the north and the south towards the equators. At the poles, the air is colder than the latitudes by about 60 degrees. The warm air at these latitudes rises up and the cold wind from the poles rushes in. In this way, wind circulation is set up from poles to the warmer latitudes.
