<b>Temporal variations in </b><b>the vertically and time averaged t</b><b>erms in the momentum equatio</b><b>ns along the channel (left panel, a and c) and across the channel (right panel, b and d) from February 5 to 13, 2014, in Exp 1 (upper panel) and Exp 2 (lower panel) at site Mo in the North Channel. Red solid line: wind stress at river surface; red dashed line: bottom friction force; black solid line: barotropic pressure gradient force; black dashed line: baroclinic pressure gradient force; green solid line: Coriolis force; green dashed line: advection; blue solid line: local variation; blue dashed line: horizontal turbulence viscosity.</b>
