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
Rockall for Kilmarnock, said: "More people have landed on the moon than have landed on Rockall." Rockall is one of the few pinnacles of the surrounding Helen's Reef; it is located 301.3 km, or 162.7 nmi west of the island of Soay, St Kilda, Scotland, and northwest of Tory Island, County Donegal, Ireland. Its location was precisely determined by Nick Hancock during his 2014 expedition. The surrounding elevated seabed is called the Rockall Bank, lying directly south from an area known as the Rockall Plateau. It is separated from the Outer Hebrides by the Rockall Trough, itself located within the Rockall
