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 Mill Creek Mountain's ridges to rise over the South Branch. For canoeists, The Trough officially begins at the SVBR's wooden trestle at Sycamore just below where Stony Run joins the river. The Trough continues its northwestern course with several bends in the river and large boulders dislocated from the ridges above dotting its shores. The Trough passes into Hampshire County at High Knob (2,648 feet) on Mill Creek Mountain followed by a series of knobs separated by spring gaps. It is at the third spring gap where Wickham was once located at on the railroad. Following Wickham, Mill Creek Mountain's
