Interestingly, there's a recent paper out which suggests that ocean heat uptake due to tropical
cyclone upper ocean mixing has been significantly overestimated in the past, so it'll be interesting to see how this develops in the community.
Not exact matches
They found increases in sea surface temperature and
upper ocean heat content made the
ocean more conducive to tropical
cyclone intensification, while enhanced convective instability made the atmosphere more favorable for the growth of these storms.
«With the hydrological cycle projected to change under global warming, impacting
upper -
ocean stratification and mixing, the results from this study have potentially important implications for understanding future tropical
cyclone activity.»
A team of scientists led by researchers at Pacific Northwest National Laboratory modified the current formula to calculate Potential Intensity by including the effects of
upper -
ocean mixing, sea - surface cooling, and salinity during a
cyclone.
Given that the other important variables (sea surface temps, depth of the warm layer, and atmospheric moisture) are all predicted to increase, it seems hard to make the claim that tropical
cyclones will be unchanged, just as it seemed unwise to claim that Lyman et al's «Recent cooling of the
upper oceans» meant that climate models had fatal flaws.
Less well understood by the scientific communities interested in hurricanes — from their basic physics to improved forecasts — and the processes controlling key physical and biological variables in the
upper ocean, are the details of coupled interactions between tropical
cyclones and the
ocean.
Cody, your explanation exactly states my premise: «But about the cooling
upper ocean, I took Stephen's comment to be referring to the fact that
cyclones funtion as gigantic heat engines that draw heat from the
upper ocean, so perhaps the ultimate effect of highly active
cyclone seasons is a cooler SST.»
But about the cooling

cyclones funtion as gigantic heat engines that draw heat from the

A recent study highlights results obtained from an aircraft
ocean survey that targeted a large warm core eddy in the eastern Caribbean Sea, where
upper ocean measurements are crucial to understanding the complexities of heat and moisture transfer during the passage of tropical
cyclones.
A
cyclone tracking scheme will be applied to reanalyses, yielding an inventory of Arctic
cyclone locations, tracks, and intensities that will provide a framework for analysis of ice and
upper -
ocean responses to storms.
The major climate system indices that are operationally used at ICPAC include evolution of monsoons, medium and
upper level winds, Madden - Julian Oscillation (MJO), Quasi Biennial Oscillation (QBO), El Niño Southern Oscillation, Indian
Ocean dipole (IOD), tropical
cyclones, sea surface temperature gradients among many others that have been derived from general circulation.
