Low pressure refers to a condition where the atmospheric pressure is lower than the surrounding areas. This often occurs in weather systems, leading to the formation of clouds and precipitation. Low-pressure systems are typically associated with stormy weather, as they can cause air to rise, cool, and condense into moisture. In meteorology, low-pressure areas are marked on weather maps and are crucial for predicting weather patterns. They can influence wind direction and speed, as air moves from high-pressure areas to low-pressure areas. Understanding low pressure helps meteorologists forecast events like rain, snow, and hurricanes.
