Sentences with phrase «jet stream patterns»

Maybe in certain locations due to changes in jet stream patterns but even that is highly unlikely in the long run.

There is some evidence that a warming world will affect jet stream patterns, which control the speed and direction of weather systems.

A new study has found that the wavy jet stream pattern that tends to bring warm winter weather to the U.S. West and cold weather to the East was set in place 4,000 years ago.

Meanwhile, a quiet sun is correlated with a stronger more meridional jet stream pattern which should cause a greater persistence in Wx.

However, to support the assertion that global warming is responsible for a great deal of damage from such events, it is sufficient to show that such events have the «signature» of global warming — for example, that specific global warming - related factors such as abnormally high sea surface temperatures, elevated water vapor levels, and altered jet stream patterns contributed to making Hurricane Sandy what it was — even if those factors can not be precisely quantified.

Over the course of a simulated 31 years, their observations indicated the jet stream would change its character about 30 to 35 times per year, a number that is consistent with current jet stream patterns.

The link between human activity and unusual jet stream patterns associated with extreme weather events is getting stronger

It's still difficult to unravel the persistent drought in California — what fraction of that is due to general global warming versus more persistent jet stream patterns because the Arctic is warming fast.

«Given this summer's ice loss, and resulting enhanced absorption of solar heat into the Arctic Ocean, it's hard to imagine that some interesting jet stream patterns won't occur this fall and winter,» she said.

The jet stream made a huge swoop that essentially cut off the majority of North America from Arctic air to the north in what meteorologists would call an extreme meridional jet stream pattern.

«We found a really strong relationship between jet stream patterns over the Pacific Ocean and U.S. hail frequency,» Gensini said.

A warmer, wetter climate is juicing the atmosphere — rapid warming of the Arctic showing up in the increasingly erratic jet stream patterns pushing weather systems across the planet.

Making accurate predictions for specific weather patterns, such as the stubborn August jet stream pattern, at a specific point in time is not possible months in advance.

Some research has linked dwindling Arctic sea ice and the rapid warming of the region to these types of wild jet stream patterns that can lead to divergent weather.

«The idea is that ice loss in this area tends to create a wavier jet stream pattern, which causes colder winters in central Asia and blocking patterns that make this weather regime very persistent.»

The study by Francis and Vavrus proposed that the added heat is altering jet stream patterns, but other mechanisms are certainly possible, as both researchers said via email.

According to Bell, the August lull was partly linked to a persistent jet stream pattern that extended from the western United States across the Atlantic Ocean to southern Europe.

«Given this summer's ice loss, and resulting enhanced absorption of solar heat into the Arctic Ocean, it's hard to imagine that some interesting jet stream patterns won't occur this fall and winter,» she said.

Cold back East and warmth out West is a jet stream pattern that has been in place for 4,000 years, according to new research

While the models do not reliably track individual extreme weather events, they do reproduce the jet stream patterns and temperature scenarios that in the real world lead to torrential rain for days, weeks of broiling sun and absence of precipitation.

La Niña favors a jet stream pattern which more consistently sends storms into the Pacific Northwest, leaving the Southwest drier than normal.

The jet stream pattern — particularly the strongly negative NAO [North Atlantic Oscillation] and associated blocking — that has been in place for the last 2 weeks and is projected to be with us into next week is exactly the sort of highly amplified (i.e., wavy) pattern that I'd expect to see more of in response to ice loss and enhanced Arctic warming.

Some scientists think that the dramatic loss of sea ice in the Arctic may be favoring this jet stream pattern.

«The idea is that ice loss in this area tends to create a wavier jet stream pattern, which causes colder winters in central Asia and blocking patterns that make this weather regime very persistent.»

«The reason why that would be is just a switch in the jet stream pattern and now is the time of the year when we expect there to be wetter conditions in April and May,» said Tony Lupo, a professor of atmospheric science at Mizzou.

One reason for this was jet stream patterns that pushed warm tropical air up into Alaska and nudged colder Arctic air down into the continental United States.

Another way looks at whether these wavy jet stream patterns are occurring more frequently across the northern hemisphere.

That affects the jet stream pattern — it basically attracts the big storms up into the Arctic,» he said.

The study by Francis and Vavrus proposed that the added heat is altering jet stream patterns, but other mechanisms are certainly possible, as both researchers said via email.

Global warming may also have influenced the jet stream pattern.
