Influence of Vertical Wind Shear on the Ocean Response to Tropical Cyclones Based on Satellite Observations by Jingru Sun, Gabriel A. Vecchi, Brian J. Soden

“…Abstract We here investigate the effects of tropical cyclone (TC)‐induced rainfall asymmetries driven by vertical wind shear on ocean salinity and temperature response to TCs using satellite and in situ observations. On average, TCs tend to initially freshen the ocean surface due to heavy rainfall and subsequently salinity from upwelling and vertical mixing, with strongest surface salinification on the right‐hand side of the Northern Hemisphere TCs. …”
