But of course, the extent of destruction from the storm surge came because a tiny bit of extra sea height can hugely amplify a storm's impact. (dotearth.blogs.nytimes.com)
These maps can be used to identify warm anticyclonic features, usually characterized by sea height anomalies and a depth of the 26 °C isotherm larger than their surrounding waters; and to monitor regions of very high (usually larger than 90 kJ cm - 2) TCHP. (aoml.noaa.gov)
