«We expected the storm would definitely get
stronger because of much
warmer sea surface temperature,» Lau said.
A second study, led by Hailan Wang of NASA's Goddard Space Flight Center, used different model simulations and came to a similar conclusion: While a
warming sea surface did make it more likely that a high - pressure ridge could form, the signal was not
strong enough to explain its extreme nature.
It's unclear whether this year's
strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the
surface water of the eastern equatorial Pacific Ocean
warms, has had any impact on the Arctic
sea ice minimum extent.
The penguins once numbered around 2,000 individuals, but in the early 1980s a
strong El Niño — a time when
sea surface temperatures in the tropical Pacific are unusually
warm — brought their numbers down to less than 500 birds.
In late 2010 and early 2011, the continent Down Under received about twice its normal complement of rain, thanks in large part to unusually
warm sea -
surface temperatures just north of Australia and a particularly
strong La Niña — in essence, combining a source of
warm humid air with the weather patterns that steered the moisture over the continent where it condensed and fell as precipitation.
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.
We do not know what the MOC has actually been doing for lack of data, so the authors diagnose the state of the MOC from the
sea surface temperatures — to put it simply: a
warm northern Atlantic suggests
strong MOC, a cool one suggests weak MOC (though it is of course a little more complex).
It could very well be that general
warming along with high
sea -
surface temperatures have lengthened the tropical storm season, making it more likely that a Sandy could form, travel so far north, and have an opportunity to interact with a deep jet - stream trough associated with the
strong block, which is steering it westward into the mid-Atlantic.
The
warm sea surface temperatures in the gyres, during hiatus decades, indicate convergence of near -
surface currents and
strong downwelling of heat.
Screen and Simmonds state in their abstract that: «Arctic
warming is
strongest at the
surface during most of the year and is primarily consistent with reductions in
sea ice cover.
Sea surface temperatures in the Western Pacific are well above climatology, and it has been argued that the warmth in the Western Pacific along with the lack of an equivalent long - term
warming trend in the Eastern Pacific, increase the chances of a «super El Niño,» comparable to the two
strongest El Niños of the past century, which occurred in 1998 and 1983.
One of the top three
strongest events on record, this particular
warming of
sea surfaces in the Pacific coincided with never before seen global heat as atmospheric CO2 levels spiked to above 405 parts per million on some days during February and March.
«With very high
sea surface temperatures that have a
strong global
warming component, these flooding events break records, and cause untold damage,» he says.
The
sea ice in the Siberian Arctic is peaking, its effect on the meridional temperature gradient
strong, promoting increased zonal flow of large - scale winds, which advect
warm air and moisture over the Eurasian continent from the Atlantic and disrupt vertical stratification near the
surface and promote high cloudiness, both of which lead to increasing temperatures — greatest at low altitudes and high latitudes.
In fact, MIT hurricane expert Kerry Emanuel first proposed in Emanuel (1987) that
warmer sea surface temperatures should lead to
stronger hurricanes.
There is growing evidence that
warmer sea surface temperatures, associated with climate change, will produce
stronger tropical cyclones.
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.
As a result of the leftover
warm water, the
sea surface temperature anomalies of the Rest - of - the - World appear to shift upwards in response to the
strong El Niño events:
In fact, without the
strong El Niño events, the Rest - of - the - World
sea surface temperature anomalies would not have
warmed since 1984:
However, who here believes that
warmer sea surface temperatures won't lead to
stronger tropical cyclones?
It is possible that «
warmer sea surface temperatures will lead to
stronger tropical cyclones» will turn out to be true for some regions of the globe, but not others.
The team's findings are controversial because they draw a connection between
stronger hurricanes and rising
sea surface temperatures — a phenomenon that has itself already been linked to human - induced global
warming.
It's unclear whether this year's
strong El Niño event, which is a naturally occurring phenomenon that typically occurs every two to seven years where the
surface water of the eastern equatorial Pacific Ocean
warms, has had any impact on the Arctic
sea ice minimum extent.
These records have been driven by the
strong El Niño and record -
warm sea surface temperatures across large parts of the Pacific and Indian oceans.
Why the
seas surface temperatures of the Atlantic, Indian and West Pacific Oceans only
warmed during the
strong El Niño events of 1986/87/88, 1997/98 and 2009/10.
Reduced equatorial cloud cover during La Nina (due to the cooler
sea surface temperature), combined with the
strong upwelling (Ekman suction) in the eastern equatorial Pacific, does indeed lead to greater
warming of the ocean - because it's bringing cool subsurface water to the
surface, where it can be heated by the sun.
And you missed a point; the satellite - era
sea surface temperature record indicates the Atlantic, Indian and Pacific
sea surface temperatures
warm after specific
strong El Niño events, not all El Niños.
that the satellite - era
sea surface temperature data indicate
sea surface temperatures
warmed naturally in response to the naturally created
warm water released from below the
surface of the tropical Pacific during
strong El Niños, and
