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 ...
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.
Definition and terminology. 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]
The presence of abundant water bodies around the subcontinent: the Arabian Sea, Bay of Bengal, and Indian Ocean. These help moisture accumulate in the winds during the hot season. The presence of abundant highlands like the Western Ghats and the Himalayas right across the path of the southwest monsoon winds.
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 ...
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).
Low-pressure area. 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 locations.
