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 ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone (ITCZ / ɪ tʃ / ITCH, or ICZ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge.

In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench , a trough can be a narrow basin or a geologic rift . These features often form at the rim of tectonic plates .
It also causes pre-monsoon rainfall especially in northern India. [citation needed] The interaction of the monsoon trough with western disturbances may occasionally cause dense clouding and heavy precipitation. The 2013 North India floods, which killed more than 5000 people in a span of 3 days, is said to be a result of one such interaction. [5]
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map .
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 ...
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 ...
