What is the role of upper tropospheric westerly trough ?
An Upper tropospheric westerly trough is important for tropical cyclone forecasting as they can force large amounts of vertical wind shear over tropical disturbances and tropical cyclones which may inhibit their strengthening. There are also suggestions that these troughs can assist tropical cyclone genesis and intensification by providing additional forced ascent near the storm centre and/or by allowing for an efficient outflow channel in the upper troposphere. The location of this trough and its intensity can also influence the movement of the storm and hence can be used for cyclone track forecasting.
