Describe the nature and importance of horizontal and vertical pressure gradients
What will be an ideal response?
Answer: Pressure gradients provide the impetus for the movement of air we call wind. The pressure gradient gives rise to a force called the pressure gradient force that sets the air in motion. Everything else being equal, the greater the pressure gradient force, the greater the wind speed. Vertical pressure gradients are very much greater than changes in horizontal pressure and strongly affect general atmospheric motions.
