pressure gradient
This term is primarily used in physics, meteorology, and fluid dynamics to describe the physical force that drives the movement of gases or liquids. It describes a state of imbalance; where a steep gradient exists, the resulting flow or wind is typically more intense.
In a meteorological context, the term is almost always used to explain the cause of wind. A "steep" or "strong" pressure gradient indicates a rapid change in pressure over a short distance, leading to high wind speeds, whereas a "weak" gradient results in calm or light winds.
