[12][13] With the cold
water concentrated around Antarctica,
sea surface temperatures and, consequently, continental
temperatures would have dropped.
Even during the region's warmest months,
sea surface temperatures can range from 80 down to below 70 degrees, and winter may bring chilly
waters in the mid 60s, and occasionally as low as 58 degrees.
NOAA Coastwatch Coastwatch is a NOAA resource that provides a variety of remotely sensed data from several different satellite platforms covering U.S. coastal
waters, including

I wonder what would happen if the same approach was applied to other climate metrics, like
sea surface temperature,
water vapor feedback strength, and precipitation - evaporation changes.
It is widely realized that WWii saw changes in the construction of sampling buckets for

Hansen et al. recently explored the effect of stratification of meltwater

Think of what would happen if you could pump cold deep
water up to the

For hurricanes, then, you'd want to ask what the

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the
surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like
water vapor and, if positive, clouds, though regional changes in
water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while
sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the
sea prevents much
temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
Hurricanes stirr up the
sea (mixing or Ekman pumping), and if there is a thin warm

Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as
sea surface temperatures, as well as deeper
water temperatures rise, the wallop of any TC over warmer
seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.
... At
sea surface temperatures above 80 Fahrenheit (27 C), evaporation loads the atmosphere with a critical amount of
water vapor... a controlling factor seems to keep the same thing from happening on Earth.
Even in cases where it is cold or where SSTs [
