- What can you say about the relationship between storm surge inundation (slides 18-19) and wind speeds (slides 26-27) caused by Hurrican SandyInundation correlates with sustained winds, but not maximum wind gustsThe maximum inundation and wind speeds occurred in similar areasMaximum inundation and wind speeds are symetric about the track of Hurricane Sandy (see wind speed slides for the hurricane track- it’s the orange line), with the maximum values occurring where the hurricane came ashore.There is no observable relationship between wind speed and storm surge inundationAlong the Atlantic coast, inundation was higher to the south while wind speeds were higher to the north.
