Sentences with phrase «seen warmer sea surface»

Not exact matches

Kevin Trenbeth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., said the study didn't account for changes in sea surface temperatures, which are the main drivers of changes in the position of the rain belts (as is seen during an El Nino event, when Pacific warming pushes the subtropical jet over the Western U.S. southward).

With higher levels of carbon dioxide and higher average temperatures, the oceans» surface waters warm and sea ice disappears, and the marine world will see increased stratification, intense nutrient trapping in the deep Southern Ocean (also known as the Antarctic Ocean) and nutrition starvation in the other oceans.

The reason could be linked to rising sea surface temperatures — fueled in part by global warming — as seen in ocean buoy data collected along the U.S. coast.

If you download 1998 - 2009 cloud cover here, and sea surface temperatures here, you can see that, except for a cloud band from ~ 0 to 10 degrees N, cloudiness is generally less where SST is warmer, though there are lots of details and spatial variation that lessen the correlation.

But this is in a period that the Bureau has predicted is likely, based on statistical analysis of historical data and current sea surface conditions, to be warmer than the historical average (see here.

Also, if you look at Table T2 in this paper, you will see that ocean sea surface heat storage 0 - 700m from 1955 - 2003 (in W / m2) is always higher at northern latitudes than the corresponding southern latitudes in every case, even with the extensive Southern Ocean warming as noted by Gavin responding to # 18.

The AARI data include drifting stations and ice information, although not the majority (my fault to see that as «main»), that means that the difference between only land based and total is in warmer sea surface temperatures.

Its hard to see how the oceans can be warming dramatically due to anthropogenic causes if the sea surface temperature (controlled for ENSO, ENSO afteraffects etc) is actually relatively stable.

This warming can be seen in measurements of troposphere temperatures measured by weather balloons and satellites, in measurements of ocean heat content, sea surface temperature (measured in situ and by satellites), air temperatures over the ocean, air temperature over land.

The record warm sea surface and atmosphere held a never before seen excess of water vapor and moisture in suspension — primarily over the Equatorial Ocean zones.

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.

To see if that could be the case, Hartmann used climate models, where he could plug in the warm sea surface temperatures and see if the East - West pattern followed.

Anthropogenic warming in the post — war period was some 0.4 degrees K. 1944 and 1998 being the peaks of 2 successive 20 to 30 year warm Pacific Ocean regimes — as seen in both sea surface and surface temperature records.

As seen in Figure 2, a cool phase PDO is associated with cool sea surface temperatures along the Pacific coast of North America, but the center of the North Pacific ocean is still quite warm.

''... worked with two sediment cores they extracted from the seabed of the eastern Norwegian Sea, developing a 1000 - year proxy temperature record «based on measurements of δ18O in Neogloboquadrina pachyderma, a planktonic foraminifer that calcifies at relatively shallow depths within the Atlantic waters of the eastern Norwegian Sea during late summer,» which they compared with the temporal histories of various proxies of concomitant solar activity... This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate Anomaly, and again after ~ 1950 A.D.» In between these two warm intervals, of course, were the colder temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near - surface water temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale temperature variability of 1 to 2 °C magnitude.»

I hypothesise that natural variations can account for the vast majority of the warming seen within the bounds of certainty in the surface and sea temperature records in the industrial era.

Though there can be significant differences in regional surface impacts between one SSW event and another, the typical pattern includes changes in sea level pressure resembling the negative phase of the North Atlantic Oscillation (NAO) / Arctic Oscillation (AO), (representing a southward shift in the Atlantic storm track), wetter than average conditions for much of Europe, cold air outbreaks throughout the mid-latitudes, and warmer than average conditions in eastern Canada and subtropical Asia (see figure below, left panel).

However, the sea surface temperatures for the Rest - of - the - World (that's not the East Pacific) has warmed so we have to detrend it for a comparison to the NINO3.4 data: As we can see, the Rest - of - the - World data warms during the El Niño events of 1986/87/88 and 1997/98 but it does not cool proportionally during the La Niña events that trailed them.

At the same time, they point towards below normal ice extent in the Barents / Kara Sea, also compared to the record minimum in 2007, which they see coupled to oceanic processes and promoting further warming of surface waters in the region.

For example over the past winter the Arctic ice cap did see unusually warm surface temperatures, yet Arctic sea ice did not shrink as some would intuitively expect it to do.

The observed patterns of surface warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).

During that time the thermometer series measure the narrow belt of warming at the sea and land surface, but the satellites do not see it until atmospheric circulation starts moving it toward the poles.

Such oscillations might also alter hurricane patterns, but the main driver of hurricanes is warm sea surface temperatures > 27C (we can all agree on that, I hope); atmospheric conditions also need to be conducive (see the above comment on this year's rip - snorting season).

(In effect, just as you will see people plot the raw sea surface temperature data and incorrectly attribute all the change in the region to «AMO», you've tracked the raw surface temperature change, and others are incorrectly attributing the entire effect to «global warming».)

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.

Ocean Heat Content data and satellite - era sea surface temperature data also indicate the oceans warmed naturally, but you have to understand that ENSO works as a recharge - discharge oscillator (with La Niña as the recharge mode and El Niño as the discharge mode) to see Mother Nature's handiwork.
