Thermal low pressure of cyclone

Warm cyclones in the lower troposphere. According to static relations (see the equilibrium state of atmospheric motion) the air pressure decreases with height, but the air pressure decrease rate at the center of a warm cyclone is much smaller than that of the surrounding atmosphere. Therefore, the thermal low pressure weakens rapidly with height. The upper part of the thermal low pressure, that is, The mid-troposphere has been replaced by warm high pressure, so thermal lows are shallower weather systems. Thermal low pressures mainly occur on the continent in summer. They are formed due to strong sunshine that warms the air in the lower troposphere. Therefore, thermal low pressures have local characteristics. South Asian lows in the lower troposphere over northern India in summer and quasi-stationary thermal lows that often occur over Turkey and western China.
