... (R = 5 km, H = 100 m, and hUI i = 1 m2/s) gives Dt = 5–6 days, which falls within the timescale of synoptic weather events. Hence, full upwelling does generally not occur for relatively short wind events of only 1–2 days or less in duration, but it may follow from a series of consecutive events. Acc ...
