Research ArticleOpen accessIn the abstractGeneral Circulation in the Malacca Strait and Andaman Sea: A Numerical Model StudySyamsul Rizal, Peter Damm, Mulyadi A. Wahid et al.In the Andaman Sea and Malacca Strait, as in other parts of the Indian Ocean, the seasonal change of the wind plays a most important role: the south-west (hereafter SW) is monsoon active from June through September and the north-east (hereafter NE) monsoon is active from December through February. During the NE monsoon the winds are directed from the north … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 11 Aug 2012 · 18,578 accessesView PDFCite
