Sentences with phrase «jet stream pattern which»

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

Not exact matches

«The jet stream changes character every 10 to 12 days, and we use this pattern to predict the weather,» said Anthony Lupo, professor of atmospheric science in MU's School of Natural Resources, which is located in the College of Agriculture, Food and Natural Resources.

The disruption to that wind pattern can reverberate through the atmosphere, impacting the flow of air from the equator to the poles, which in turn can affect the jet stream and weather around the globe.

Large belts and zones form a consistent pattern of jet streams which give the planet its familiar striped appearance.

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

The temperature differential between the cold of the far North and the warmer air of the temperate zones to the south fuel the jet stream, which steers weather patterns in the Northern Hemisphere.

This shifts around wind patterns there and has a domino effect through the atmosphere; over the U.S., it causes a shift in the position of the wintertime jet stream, which controls how storms move across the country.

«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 current La Nina event and natural variability are also involved, and it is difficult to say which effect is mostly responsible for the current jet stream pattern.

Reading the numerous references there is clear evidence of «blocking patterns,» perhaps as the jet stream shifts, or a high pressure takes up residence, feeding in winds from a certain direction which generally shape British weather.»

First, the west - to - east jet stream appears to be slowing down, which allows weather patterns to persist in certain areas for longer.

4) A change in global weather patterns which I noticed as long ago as 2000 whereby the jet streams moved back towards the equator from the positions they adopted during the warming spell.

A strong El Niño heats up the atmosphere and changes circulation patterns around the globe, especially the jet stream over the Pacific, which becomes stronger and dumps more frequent and intense storms over the western U.S., especially California.

Because these waves in the jet stream were so big, Francis says, that pattern became very powerful, which is why it persisted for so long.

As the air gets hotter, thunderstorms are more likely to develop in the area, the energy of which fluctuates the jet stream and creates a high - low or «dipole,» pressure pattern.

This, in turn, causes disruptions in the jet stream which brings huge fluctuations in local weather patterns — of highs AND lows, precipitation AND drought.

Examination of daily ozone and jet stream satellite data reveals a process which responds to wandering magnetic poles which affect jet streams and Rossby wave loops to exacerbate extreme weather patterns and cause global climate change.

The pattern is also associated with the negative phase of the Arctic Oscillation, which is the dominant atmospheric pattern observed during severe winters and comprises a weakened jet stream and more cold air intrusions southward from the Arctic into North America and Eurasia.

The new study, along with other previously published research, showed that the decline in sea ice and snow cover has slowed the west - to - easterly component of the jet stream, thereby enhancing the north - to - south waviness of the jet, which leads to the creation of more stagnant or «blocked» weather patterns.

A negative AO changes pressure patterns at higher latitudes which influence the shape of the jet stream.

We found that relative to the global - mean trends of the respective layers, both hemispheres have experienced enhanced tropospheric warming and stratospheric cooling in the 15 to 45 ° latitude belt, which is a pattern indicative of a widening of the tropical circulation and a poleward shift of the tropospheric jet streams and their associated subtropical dry zones.
