This deficit relative to pressure farther away at the same altitude creates a pressure-gradient force that pulls air inward to fill the space vacated by the rising, buoyant air. The reverse ...

In particular, near the shoulder, the pressure gradient changes from being negative (decreasing pressure) to positive (increasing pressure). The force due to pressure differences changes sign from ...

The difference in pressure between these two systems, called a pressure gradient force, is strong. This means a high wind event across southern New England is expected, beginning Wednesday night.

Intense Santa Ana winds gusting over 70 miles per hour are the major contributing factor to the massive California wildfires ravaging the Los Angeles area, not only exacerbating the deadly fires but ...
