Sentences with phrase «for changes in jet stream»

One was published several months ago in Geophysical Research Letters by James Screen and Ian Simmonds, who looked for changes in jet stream characteristics using a different methodology than that of Francis and Vavrus.

Virtually ice - free summers in the arctic sea could well arrive by 2030, with troubling implications for accelerated albedo feedback and possibly disruptive changes in the jet stream.

For instance, changes in ocean convection over the north Atlantic would affect the jet stream, which would have a dramatic effect upon regional precipitation, probably leading to acute drought in the northern hemisphere, which will weaken and push the northern jet stream toward the Arctic.

One minute change in the atmospheric regime can slowly effect further changes in the system and the chain reaction can occur, which, in the end, could shift a jet stream a few kilometres and create conditions possible for storm intensification, which may result in the flooding of an area where the storm would not have been or would have been greatly minimised.

But passengers won't just have to keep their seat belts locked, they may have to stay locked in for longer, as jet stream wind patterns change.

I think there is evidence that AGW has caused the decline in arctic sea ice, which may be responsible for the changes seen in the paths of the jet stream, which may be responsible for the blocking high over Greenland which was responsible for Sandy's left turn.

You say that there is evidence that AGW has caused the decline in arctic sea ice, which may be responsible for the changes seen in the paths of the jet stream, which may be responsible for the blocking high over Greenland which was responsible for Sandy's left turn.

There have been many primarily anthropogenic changes in the past, but the major jet stream changes caused by the retreat of the North American Ice Shield seems to be much more determinative for Holocene changes in Saharan rainfall.

The reason for the change in the shape and positions of atmospheric jet streams is, for now, an issue of debate, with AA as one of the potential candidates (see, e.g., refs.

The advantage of recognising a reversed sign for the solar effect high up in the atmosphere is that it enables a scenario whereby the bottom up effects of ocean cycles and the top down effects of solar variability can be seen to be engaged in a complex ever changing dance with the primary climate response being changes in the tropospheric air circulation systems to give us the observed natural climate variability via cyclical latitudinal shifts in all the air circulation systems and notably the jet streams.

This can change the path of the jet stream and slow it down, leaving weather systems in the same place for a longer time.

While climate change does not affect Earth's tilt, it does have potential implications for many of the other factors that influence winter weather in the US, including Arctic sea ice, the polar jet stream, the polar vortex, and El Niño.
