«We expected the storm would definitely get stronger because of
much warmer sea surface temperature,» Lau said.
Not exact matches
The future of the currents, whether slowing, stopping or reversing (as was observed during several months measurements), could have a profound effect on regional weather patterns — from colder winters in Europe to a
much warmer Caribbean (and hence
warmer sea surface temperatures to feed hurricanes).
«Human influence is so dominant now,» Baker asserts, «that whatever is going to go on in the tropics has
much less to do with
sea surface temperatures and the earth's orbital parameters and
much more to do with deforestation, increasing atmospheric carbon dioxide and global
warming.»
The warmth was due to the near - record strong El Niño that developed during the Northern Hemisphere spring in the eastern and central equatorial Pacific Ocean and to large regions of record
warm and
much warmer - than - average
sea surface temperatures in parts of every major ocean basin.
Much warmer - than - average
temperatures engulfed most of the world's oceans during June 2016, with record high
sea surface temperatures across parts of the central and southwest Pacific Ocean, northwestern and southwestern Atlantic Ocean, and across parts of the northeastern Indian Ocean.
Any way you look it, from the Climate Prediction Center Outlook through May, to the ongoing
warm anomalies in land and
sea surface temperatures,
much of the United States is likely to find above average
temperatures in the coming months.
Much of the recent
sea ice loss is attributed to
warmer sea surface temperatures with southerly wind anomalies a contributing cause [Francis and Hunter, 2007; Sorteberg and Kvingedal, 2006], with thermodynamic coupling leading to associated increases in atmospheric moisture.»
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).
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.
The difficulty arises because oceanic
sea -
surface temperatures warm up at a
much slower rate than those above land.
While consistent with the IPCC assessments of historical
warming, it lacks coverage of
much of the fast -
warming Arctic region and blends
surface air
temperatures over land with slower -
warming sea surface temperatures over the ocean.
The
warm expanse has been characterized by
sea surface temperatures as
much as three degrees C (about 5.4 degrees F) higher than average, lasting for months, and appears on large - scale
temperature maps as a red - orange mass of
warm water many hundreds of miles across.
The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian Ocean as a mirror of the Pacific Ocean
sea surface temperature anomalies [
much like the Western Hemisphere
Warm Pool creates such a SST mirror with the Atlantic Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively cool as strong trade winds blow the tropically Sun -
warmed waters far towards the west.
There are plenty of
much clearer ones, from increasing
surface temperature (the global
warming itself), to melting of ice on land and
sea, to the long - term cooling of the stratosphere, increasing intensity of heavy rain events, etc..
[later in the report:]
Sea surface temperatures during June 2009 were
warmer than average across
much of the world's oceans, with the exception of cooler - than - average conditions across the southern oceans.
Although it may be reasonable to assume that the Hadley circulation will weaken as the atmosphere
warms, the fate of coastal
sea surface temperatures worldwide is
much more ambiguous.
However, ocean
temperatures have
warmed almost everywhere on the planet, with 0.5 ºC being the global mean rise of
sea surface temperature, hence Trenberth's reasonable estimate that this
much is the contribution from global forcings like CO2.
Not only that, but there is increasingly compelling evidence that the recent short - term slowdown in the
surface temperature record was
much less pronounced than previously estimated, if rapid Arctic
warming is fully reflected, along with potential biases from the changing mix of
sea surface temperature measurement sources in recent years.
That's a key reason
surface temperatures haven't appeared to
warm as fast as many had expected in the past ten years — although ocean
warming has sped up, and
sea level rise has accelerated more than we thought, and Arctic
sea ice has melted
much faster than the models expected, as have the great ice sheets in Greenland and Antarctica
Specifically, the study found that» [d] uring
much of last year's hurricane season,
sea -
surface temperatures across the tropical Atlantic between 10 and 20 degrees north... were a record 1.7 degrees F above the 1901 - 1970 average,» «global
warming explained about 0.8 degrees F of this rise,» while» [a] ftereffects from the 2004 - 05 El Nino accounted for about 0.4 degrees F,» and a natural cycle in
sea -
surface temperatures «explained less than 0.2 degrees F of the rise.»
There was so
much warm water released by the 1997/98 El Niño that the
sea surface temperatures for the entire East Pacific Ocean (from pole to pole or the coordinates of 90S - 90N, 180 - 80W) temporarily
warmed 0.5 to 0.6 deg C. See Figure 4.
