A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least 119 km/h (74 mph). [1] This region is referred to as the Northwestern Pacific Basin, [2] accounting for almost one third of the world's tropical cyclones.
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.
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 ...
Tropical monsoon climates have monthly mean temperatures above 18 °C (64 °F) in every month of the year and a dry season. [1]: 200–1 The tropical monsoon climate is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate).
Each year on average, around 80 to 90 named tropical cyclones form around the world, of which over half develop hurricane-force winds of 65 kn (120 km/h; 75 mph) or more. [1] Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each ...
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 ...
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of 18 °C (64 °F) or higher in the coolest month, featuring hot temperatures and high humidity all year-round. Annual precipitation is often abundant ...
The Philippines has five types of climates: tropical rainforest, tropical monsoon, tropical savanna, humid subtropical and oceanic (the latter two are found in higher-altitude areas). The country overall is characterized by relatively high temperature, oppressive humidity and plenty of rainfall. There are two seasons in the country: the wet ...
