What is Low-pressure area or depression?
A low-pressure area, which is also known as depression, refers to a region where the atmospheric pressure is lower than that of surrounding locations. Thermal lows form due to localized heating caused by sunshine over the land masses. The warm air is less dense than their surroundings, resulting in rising of the warm air. This lowers atmospheric pressure in that particular portion of the Earth's surface. When there are thermal lows in large scale, they help drive monsoon circulations resulting in rainfall.
