THERMAL LOW Also known as heat low, it is an area of low pressure due to the high temperatures caused by intensive heating at the surface. It tends to remain stationary over its source area, with weak cyclonic circulation.
Thermal Lows Areas of low pressure that are shallow in vertical extent and are produced primarily by warm surface temperatures.
THERMAL LOW- A surface low pressure caused by intense surface heating. Thermal lows weaken with height since the source of heating is at the surface. They commonly occur in desert regions in summer.
THERMAL LOW - A region of low pressure produced when air is heated and rises. Usually forms over hot desert regions. Smaller thermal lows may form over large cities and forest fires.
Frontal lows are temperate zone phenomena, and develop along the polar front as a result of the interaction between cold and warm surface air masses. Thermal lows also form over areas such as Death Valley as the result of intense ground heating; ...
Warm-core cyclone A surface, synoptic-scale stationary cyclone that develops as a consequence of intense solar heating of a large, relatively dry geographical area; same as a thermal low. ...
