Sentences with phrase «atmospheric blocking»

And the new study uses a suite of climate models to suggest that such atmospheric blocking patterns will be less frequent, rather than more frequent, in the future.

I'll consider what you say but right now am tied up between work commitments and some work on atmospheric blocking.

The natural process of atmospheric blocking, and the climate impacts induced by such blocking, are the principal cause for this heat wave.

Cornell and Rutgers researchers report in the March issue of Oceanography that the severe loss of summertime Arctic sea ice - attributed to greenhouse warming - appears to enhance Northern Hemisphere jet stream meandering, intensify Arctic air mass invasions toward middle latitudes, and increase the frequency of atmospheric blocking events like the one that steered Hurricane Sandy west into the densely populated New York City area.

Lupo, in collaboration with Russian researchers from the Russian Academy of Sciences, will simulate atmospheric blocking using computer models that mirror known blocking events, then introduce differing carbon dioxide environments into the models to study how the dynamics of blocking events are changed by increased atmospheric temperatures.

Such atmospheric blocks are expected to result from melting sea ice, some researchers say — a claim that has added fuel to a contentious dispute over the global influence of the warming Arctic.

He cites a global weather phenomenon, called atmospheric blocking, as an example of a planet - wide occurrence that is has already affected his forensic micrometeorology endeavors.

D'Andrea, F., et al., 1998: Northern Hemisphere atmospheric blocking as simulated by 15 atmospheric general circulation models in the period 1979 — 1988.

iii) The failure of outgoing longwave radiation (OLR) to show that there was any increased atmospheric blocking of outgoing radiation following short term troposphere warming episodes.

Structure and impact of atmospheric blocking over the Euro - Atlantic region in present day and future simulations.

«The North American location of increased 700 hPa positive anomalies suggests that a regional atmospheric blocking mechanism is responsible for the presence of the AD pattern, consistent with observations of unprecedented high pressure anomalies over Greenland since 2007.»

Other proposed mechanisms confine the Arctic's influence on large - scale circulation changes to the troposphere, in which a warmer Arctic favors a wavier flow and more persistent atmospheric blocking, which often spawns extreme weather events58, 59.

Masato and his colleagues looked at how the magnitude and frequency of atmospheric blocking events in the Atlantic - Europe region is projected to change in the future according to four climate models which the authors claim match the observed characteristics of blocking events in this region pretty well.

Fortunately the European ECMWF weather models accurately forecasted Sandy's storm track 8 to 9 days in advance due to a better understanding of atmospheric blocking (in this case the high pressure south of Greenland) and the effects of the jet stream.

In the past two years, up and down the eastern seaboard, atmospheric blocking has directly led to snowfall in areas where heavy snow is uncommon, and consequently, «hundreds of slip - and - fall cases» have come across Lombardo's desk.»

He is interested in the relationship between extreme events, storm activity and atmospheric blocking, and how the circulation changes as the climate warms.

To suggest a route the study also names an atmospheric blocking pattern that would resemble a negative Arctic Oscillation, but would in fact be something else.

A blocking high, or blocking low or any other type of atmospheric block, is a stationary pattern in the atmosphere that causes weather to remain unchanged for days or weeks.

In fact, many of the newest generation of climate models show that atmospheric blocking will become less common in the North Atlantic than it is now.
