Sentences with phrase «surface warming signal»

Not exact matches

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.

Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.

In general, the regions of expanding warming upwelling water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the surface, and the regions of shrinking, cooling, sinking water in the Arctic must create slight depressions in the sea surface (again, I mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).

By the way, low clouds in darkness increase surface temperature, sort of like the inverse property of commonly understood Cosmic ray effect, not causing a cooling because there are more CR's, but rather a warming, which only low clouds in total darkness can do, so the probable CR temperature signal gets cancelled from one latitude dark vs bright region to the next.

«The climate patterns responsible for the expected above - normal 2007 hurricane season continue to be the ongoing multi-decadal signal (the set of oceanic and atmospheric conditions that have spawned increased Atlantic hurricane activity since 1995), warmer - than - normal sea surface temperatures in key areas of the Atlantic Ocean and Caribbean Sea, and the El Nino / La Nina cycle»

Nonetheless, even if the substantial recent trend in the AO pattern is simply a product of natural multidecadal variability in North Atlantic climate, it underscores the fact that western and southern Greenland is an extremely poor place to look, from a signal vs. noise point of view, for the large - scale polar amplification signature of anthropogenic surface warming.

There is no evidence of an «anthropogenic greenhouse warming» signal in the warming of satellite - era sea surface temperatures.

The global warming signal itself is a multidecadal feature of the climate, but just like the seasonal example above, it has been possible at times to take one period of one temperature record - surface air temperatures in most cases - and do a «January - February» job with it, thereby making the claim that temperatures are flatlining or even cooling.

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.

Sea surface temperature anomalies that persist over many years can be signals of regional or global climate change, such as global warming.

What do you think of the suggestion from parts of the media that it will signal the end of the so - called surface warming slowdown?

He has demonstrated that the surface temperature warming signal correlates strongly with urbanization and growth:

According to Gerry Bell, Ph.D., NOAA's lead seasonal hurricane forecaster, the major climate factors expected to influence this year's activity are the ongoing multi-decadal signal, which produces wind and atmospheric pressure patterns favorable for hurricane formation, along with ongoing warmer - than - normal sea surface temperatures.

Foster and Rahmstorf (2011) have published a paper in Environmental Research Letters seeking to extract the human - caused global warming signal from the global surface temperature and lower troposphere temperature data.

The Berkeley earth surface temperature project (BEST) also confirm that one third of the Globes weather stations show a cooling, not warming, signal again demonstrating that no single global climate prevails.

The attempt would be similar in principle to the current efforts at abstracting a believable global warming signal from the networks of surface - temperature observations.

Fig. 3 shows that the resulting cleaned signal presents a nearly monotonic warming of the global mean surface temperature throughout the 20th century, and closely resembles a quadratic fit to the actual 20th century global mean temperature.

Removal of that hidden variability from the actual observed global mean surface temperature record delineates the externally forced climate signal, which is monotonic, accelerating warming during the 20th century.

In his presentation, Gerry Bell, Like Lautenbacher, associated conditions since 1995 to «multi-decadal signal along with warmer than normal sea surface temperatures.»

And the sea surface temperature and ocean heat content data do not support the existence of a human - induced global warming signal.

The question is: how significant is this spurious warming signal in the overall «globally and annually averaged land and sea surface temperature» record?
