KNOXVILLE (WATE) – Wind is simply air that is moving.
While you can’t actually see wind, we can measure its motion by the force it applies on objects. The WATE 6 Storm Team uses pressure gradients to measure which direction and at what rate the pressure at a particular location. This helps us predict the direction and force of winds.
Pressure gradient is the difference in pressure between high and low pressure areas. Wind speed is directly proportional to the pressure gradient. This means the strongest winds are in the areas where the pressure gradient is the greatest.
