Answer:
Explanation:
the motion of surface winds in the Northern hemisphere on Earth due to the uneven heating of the atmosphere and Coriolis force. Due to the Earth's rotation, surface winds have different speeds at different latitudes as follows:
Surface winds travel faster closer to the equator (0 degrees latitude).
Surface winds travel slower closer to the North pole (90 degrees latitude).
Doldrums is the calm area near the equator.
