Tropical cyclone
Rapidly rotating storm system
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is…Source: Wikipedia (CC BY-SA)
Atmospheric pressure
Static pressure exerted by the weight of the atmosphere
Atmospheric pressure, also known as air pressure or barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inches Hg,…Source: Wikipedia (CC BY-SA)
Bar (unit)
Unit of pressure equal to 100,000 Pa
The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level. By the barometric formula, 1 bar is roughly…Source: Wikipedia (CC BY-SA)
