What does a ridge represent in meteorological terms?

A ridge in meteorological terms represents a U-shaped extension of a high-pressure system. It is important to understand that ridges are associated with areas of high pressure where the atmospheric pressure is higher than that of the surrounding areas. This structure often leads to fair weather and can influence temperature and storm systems in the region.

The U-shape of the ridge signifies a particular arrangement of the isobars (lines of equal pressure) on a weather map, indicating an upward bulge of the high-pressure system. This characteristic helps forecasters predict weather patterns, as ridges are often responsible for creating stable conditions that inhibit cloud formation and precipitation. Consequently, understanding ridges is essential for interpreting weather forecasts and analyzing atmospheric phenomena.
