how the pressure gradient force determine the direction of wind
Answers
Explanation:
Wind ultimately comes from temperature differences because, as we learned in another lesson, temperature differences lead to air pressure differences, and air pressure creates convection currents, which, as we just learned, create wind. Let's back up and see how this works. Say we have a warm location, like the equator, and a cold region, like the North Pole. Air at the equator is warmed with more solar energy than the air at the North Pole, so it rises and then moves horizontally toward the North Pole. As it cools, it sinks back down toward the warmer equatorial region. The air pressure difference between the two locations is called the pressure gradient, and the force that actually drives the air from high pressure areas to low pressure areas is called the pressure gradient force.
