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
The Trough a "true whitewater run" (difficulty level = Class I-II). It is, however, a markedly beautiful stretch of river. The Trough General Store in Glebe at The Trough's mouth offers canoe rentals and shuttles canoers and kayakers to The Trough's opening near McNeill in the South Branch Wildlife Management Area.
