Hurricanes can significantly cool the sea surface over which they pass. They do so by churning up cooler water from below, and by removing heat from the ocean surface via evaporation of sea water. Before Hurricane Felix, the water around Bermuda was warm as indicated by the orange tones in this satellite image. After the Hurricane, the surface waters cooled by several degrees, this can be seen in the cooler (green color) patch around Bermuda. The black areas in the image represent cloud cover. Satellites provide a regional view that extends the BATS data, which are taken at one point in the ocean. |
