What is the difference between storm surge and storm tide?

26 November 2012, 4:23 pm

Storm surge is the abnormal rise in seawater level during a storm, measured as the height of the water above the predicted astronomical tide. The surge is caused primarily by a storm’s winds pushing water onshore. The amplitude of the storm surge at any given location depends on the orientation of the coast line with the storm track; the intensity, size, and speed of the storm; and the local bathymetry.
