Pressure readings can help determineweather and wind conditions in an area. High pressure areas are generally associated with fair weather. Low pressure areas are generally associated with clouds and thechance of precipitation. Isobars that are packed closely together show a strong pressure gradient. Strong pressure gradients are associated with areas of stronger winds.Pressure units can be displayed in Millibars (mb), Inches of Mercury (in), and Hectopascals (hPa).
