Hurricane Sea to Air Heat Transfer
Presentation made at the American Meteorological Society 18th Air Sea Interaction Conference, July 2012
Hurricane cooling is usually attributed to upwelling and mixing of cold water from below. The presentation proposes the opposite hypothesis, namely that: “Hurricane sea cooling is almost entirely due to heat removal from above and not to cold water from below”.

Revisions to Spray Production and Deposition Areas
The original 18th Air Sea Interaction conference presentation suggested that spray is produced mainly under the eyewall of the right rear quadrant and then deposited to the right of the hurricane track. This revised theory suggests that the spray is produced along the hurricane track and carried by the wind to the right of the hurricane track. See link to figures showing the revised and original spray production and deposition areas. The revised theory is based on the surface and subsurface sea temperature measurements in paper: Cold Wake of Hurricane

Abstract
Warm sea water is the energy source for hurricanes. Interfacial sea‑to‑air heat transfer without spray ranges from 100 W m-2 in light wind to 1000 W m-2 in hurricane force wind. Spray can increase sea‑to‑air heat transfer by 2 orders of magnitude and result in heat transfers of up to 100,000 W m-2. Drops of spray falling back in the sea can be 2 to 4 °C colder than the drops leaving the sea thus transferring a large quantity of heat from sea to air. The heat of evaporation is taken from the sensible heat of the remainder of the drop; evaporating approximately 0.3% of a drop is sufficient to reduce its temperature to the wet bulb temperature of the air. The heat required to evaporate hurricane precipitation is roughly equal to the heat removed from the sea indicating that sea cooling is due to heat removal from above and not to the mixing of cold water from below. The paper shows how case studies of ideal thermodynamics processes can help explain hurricane intensity.

considered
the
definitive information source for the power generation market. We
covered the earliest advances of steam power plants in the 1800s and
addressed energy supply issues during World Wars I and II. We were the
first to report on the birth of nuclear power, and today we report on
modern advanced power technologies, including wind, solar, tidal, and
ultrasupercritical generation. Our coverage of the worldwide power
generation industry, which includes all fuel types and generation
technologies, has never been more critical as the world grapples with
so many supply options and regulatory hurdles."

New Unpublished Manuscript - Hurricane Isabel Intensity
Recent dropsonde observations in hurricane Isabel provided
unprecedented high quality data on eyewall: air temperature, relative
humidity and sea surface temperature. This January 2007 manuscript
shows that eyewall temperature and humidity can be used to calculate
minimum eyewall pressure and maximum wind speed.
