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

However, in 1997, the UK ratified the United Nations Convention on the Law of the Sea (UNCLOS), limiting territorial sea claims to a 12-nautical-mile, or 14 mile (22 km), radius, and therefore allowing free passage in waters beyond this. In 1988, the United Kingdom and Ireland signed an EEZ boundary agreement for which "the location of Rockall was irrelevant to the determination of the boundary". In 1997, the UK ratified UNCLOS, which states that "Rocks which cannot sustain human habitation or economic life
