August position of the ITCZ and monsoon trough in the Pacific Ocean, depicted by area of convergent streamlines in the northern Pacific. 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 ...
The South Pacific convergence zone (SPCZ) is a reverse-oriented, or west-northwest to east-southeast aligned, trough extending from the west Pacific warm pool southeastwards towards French Polynesia. It lies just south of the equator during the Southern Hemisphere warm season, but can be more extratropical in nature, especially east of the ...
The South Pacific Convergence Zone (SPCZ), a reverse-oriented monsoon trough, is a band of low-level convergence, cloudiness and precipitation extending from the Western Pacific Warm Pool at the maritime continent south-eastwards towards French Polynesia and as far as the Cook Islands (160W, 20S).
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. This ...
Low-pressure areas can also form due to organized thunderstorm activity over warm water. When this occurs over the tropics in concert with the Intertropical Convergence Zone, it is known as a monsoon trough. Monsoon troughs reach their northerly extent in August and their southerly extent in February.
However, the monsoon is not a simple response to heating but a more complex interaction of topography, wind and sea, as demonstrated by its abrupt rather than gradual withdrawal from the region. The Australian monsoon (the "Wet") occurs in the southern summer when the monsoon trough develops over Northern Australia. Over three-quarters of ...
The Asian monsoon and Indian Ocean monsoon are known for bringing intense rainfall after an extended dry period. Goa, a state in southwestern India, is generally rainless from January through March.
The trough attracts moist air from the encompassing oceans and this inflow of moist air is referred to as the monsoon. [ 7 ] During the "active" phase or "bursts", large regions of cloud and rain are formed, where there is a constant northwesterly wind on the north area of the trough, alongside heavy rainfall on the land, which last from about ...
