Sentences with phrase «wavy jet stream pattern»

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.

«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.»

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

Not exact matches

What we * do * suggest is that the weakened poleward temperature gradient owing to the rapidly warming Arctic relative to mid-latitudes (Arctic amplification) should increase the north - south component of the upper - level flow, making highly wavy jet - stream patterns (like the one this winter) more likely.

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.

Evidence for a wavier jet stream in response to rapid Arctic warming New metrics and evidence are presented that support a linkage between rapid Arctic warming, relative to Northern hemisphere mid-latitudes, and more frequent high - amplitude (wavy) jet - stream configurations that favor persistent weather patterns.

A 2015 study by Francis and Stephen Vavrus, «Evidence for a wavier jet stream in response to rapid Arctic warming» concluded that global warming was driving an increase in the most extreme events because of «more frequent high - amplitude (wavy) jet - stream configurations that favor persistent weather patterns.»
