Sensing Cold Wakes from Tropical Cyclones

The combination of MODIS True Color imagery with Multiscale Ultrahigh Resolution (MUR) Sea Surface Temperature Anomaly (SSTA) data reveals cold wakes, or trails of upwelled cold subsurface water (dark blue areas), after passage of Hurricane Florence and other tropical cyclones in the Atlantic.

Exploring the State of the Ocean

Cold wakes, or trails of upwelled cold subsurface water, are easily seen as dark blue areas trailing tropical cyclones and can be observed using PO.DAAC’s State Of The Ocean (SOTO) tool. SOTO is an interactive, web-based tool that enables the analysis of a wide range of remotely-sensed ocean data.
