Which is the correct definition of an anticyclone?
An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone ).
How are light winds related to anticyclones?
Light winds circulate around the central area of high pressure in a clockwise direction in the northern hemisphere. Within the anticyclone air is descending. Air descends in an anticyclone. As the air descends, it is compressed and warmed.
Who was the first person to discover anticyclone?
In 1860s, anticyclone was discovered for the first time by Sir Francis Galton. The cum sole is used to define the circulation of anticyclone. It comes in high pressure system. Get facts about Antarctica here.
Are there any other planets that have anticyclones?
Anticyclones can also occur on other planets, such as Jupiter, where there are two types, namely the Oval BA and Great Red Spot anticyclones. The winds of an anticyclone typically blow from regions of high pressure towards regions of low pressure.
When does the anticyclone loop in the ocean stop?
This loop stops once ocean temperatures cool to below 26.5 °C (79.7 °F), reducing the thunderstorm activity, which then weakens the upper-level high-pressure system. When the subtropical ridge in the Northwest Pacific is stronger than normal, it leads to a wet monsoon season for Asia.
When did Sir Francis Galton discover the anticyclone?
Sir Francis Galton first discovered anticyclones in the 1860s. Preferred areas within a synoptic flow pattern in higher levels of the hydrosphere are beneath the western side of troughs, or dips in the Rossby wave pattern. High-pressure systems are alternatively referred to as anticyclones. Their circulation is sometimes referred to as cum sole.
