A clockwise spinning low-pressure area or cyclone of southern Australia. The center of the spiral-shaped cloud system is also center of the low. A low-pressure system over Iceland. In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding
A polar cyclone is a low-pressure weather system, usually spanning 1,000 kilometres (620 mi) to 2,000 kilometres (1,200 mi), [54] in which the air circulates in a counterclockwise direction in the northern hemisphere, and a clockwise direction in the southern hemisphere. The Coriolis acceleration acting on the air masses moving poleward at high ...
The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude.
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
What is a bomb cyclone? Bomb cyclones are low pressure systems that undergo what meteorologists call "bombogenesis." Bombogenesis occurs when a midlatitude cyclone ("midlatitude" meaning the area ...
Out of all these tropical cyclones, Typhoon Tip had the lowest atmospheric pressure measured in a tropical cyclone, at 870 mbar (25.69 inHg). It is the third image in the first row. This is a list of the most intense tropical cyclones as measured by minimum atmospheric pressure at sea level.
