Monsoon trough of the summertime Asian monsoon is in its normal orientation (oriented east-southeast to west-northwest), tropical cyclones along its periphery will move with a westward motion. If it reverses its orientation, orienting southwest to northeast, tropical cyclones will move more poleward. Tropical cyclone tracks with S-shapes tend to be associated with reverse-oriented monsoon troughs. The South Pacific convergence zone and South American convergence zones are generally reverse oriented. The failure of the monsoon trough, or the ITCZ, to move south of the equator in the eastern Pacific Ocean and Atlantic Ocean during the southern hemisphere summer, is considered one of the
Brent Spar to this search: firstly, that the site was within the UK exclusive economic zone, and secondly, that the site be deep enough that the sunken buoy would present no hazard to shipping. FRS identified three sites as squares, which were considered suitable; the Maury Channel, the North Feni Ridge and the Rockall Trough. At these three sites, FRS carried out: The North Feni Ridge was found to include a narrow channel. The Rockall Trough area was found to be a gently sloping basin between the Anton Dohrn Seamount and the Wyville-Thomsom Ridge. The Maury Channel area was found to be
