A monsoon (/ m ɒ n ˈ s uː n /) is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation [1] but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator.
t. e. A tropical cyclone is a rapidly rotating storm system with a low-pressure center, 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 called a hurricane (/ ˈhʌrɪkən, - keɪn /), typhoon ...
A typical instigator of August hurricane activity is the West African monsoon trough. Monsoon waves come off the west coast of Africa and often become storms as they trek across the Atlantic.
The North American monsoon, variously known as the Southwest monsoon, the Mexican monsoon, the New Mexican monsoon, or the Arizona monsoon[1] is a term for a pattern of pronounced increase in thunderstorms and rainfall over large areas of the southwestern United States and northwestern Mexico. Geographically, the weather pattern is centered ...
Powerful monsoon storms moved through Arizona, Utah and Colorado on Aug. 21-23, 2024, with intense downpours, hail, heavy winds, flooding and lightning. In comparison, most of the summertime in ...
Of the major monsoon systems, only the North American monsoon is expected to have substantial decreases in total precipitation, with the most likely outcome being a 1%-6% reduction in summer rainfall.
The monsoon trough is a portion of the Intertropical Convergence Zone in the Western Pacific, [1][2] as depicted by a line on a weather map showing the locations of minimum sea level pressure, [1] and as such, is a convergence zone between the wind patterns of the southern and northern hemispheres. Westerly monsoon winds lie in its equatorward ...
The 2021 Atlantic hurricane season was the third-most active Atlantic hurricane season on record in terms of number of tropical cyclones, although many of them were weak and short-lived. With 21 named storms forming, it became the second season in a row and third overall in which the designated 21-name list of storm names was exhausted.
