Global and Regional Variability of Tropical Cyclone-induced Ocean Warming
We examine the magnitude and cumulative footprint of subsurface warm anomalies forced by tropical cyclones, making use of a high resolution global ocean circulation model. Analysis of a 20-year simulation using a realistic global tropical cyclone distribution reveals how the ocean adjusts to tropical cyclone-induced warming. Lateral transport of the warm anomalies plays a key role in redistribution of heat between the ocean basins and maintaining the ocean heat balance. Tropical cyclones induce semi-permanent warming of the upper thermocline in some regions that can reach as much as 1/4C. Transport pathways and ventilation mechanisms are regulated by the large-scale seasonal and interannual climate variability, such as the Asian monsoon and El Nino Southern Oscillation.
