Impact of Typhoons on the Western Pacific: Temporal and Horizontal Variability of SST Cooling
2011
Price, James F
The long term goal is to understand how the spatial variation of ocean and hurricane parameters, e.g., upper ocean temperature gradient, initial mixed-layer depth, etc., contribute to hurricane-ocean interaction. With this understanding we should then be in position to make better forecasts of hurricane-ocean interaction, and especially of hurricane intensity. The phenomenon of direct interest is the cooling of SST caused by hurricanes and typhoons, typically 2 to 5 deg C. The objective of this project is to make a quantitative estimate of the sensitivity of SST cooling to the hurricane and ocean variables that contribute to SST cooling. These include the ocean initial condition, e.g., if a mesoscale eddy is present, hurricane translation speed and hurricane intensity, among others. Emphasis here is upon ocean variability.
