They lose intensity as they travel inland or out to sea. Sea breezes and land breezes are strongest at the shoreline, where temperature and pressure differences are most pronounced. The resultant land breeze flows from the high-pressure area, over the shore, out to the low-pressure area, over the water. At night, the process is reversed as the land loses heat more quickly than does the water. A mild wind blows across the pressure gradient, from the high-pressure area (over the water) to the low-pressure area (over the land). As a result, a low-pressure area develops over warm ground and a high-pressure area over the cooler water. Sea breezes form on hot days because the land warms more rapidly than does the water. A land breeze, in contrast, blows from the shore toward the water. It comes as a welcome relief to coastal inhabitants on a hot day. A sea breeze blows from the water to the shore. Sea breezes and land breezes are two familiar categories of local winds that are driven by differences in temperature and in air pressure, which is the pressure exerted by air on a given area. ![]() In addition, local winds have many interesting and descriptive names. ![]() Regardless of their cause, local winds have certain general characteristics. Local winds can be driven by temperature and pressure differences or by variations in topography, the shape and height of Earth's surface features. ![]() A local wind can persist anywhere from several minutes to several days. Mesoscale winds are better known as local winds or regional winds. Mesoscale winds are winds that blow across areas of the surface ranging from a few miles to a hundred miles in width.
