Sentences with phrase «of jetstreams»

It may not be that the WORLD is drier when there are fewer sunspots, but that our weather patterns change (we appear to be having a lowering of the jetstreams towards the equator recently).

The size and intensity of the polar vortexes then has an effect on the latitudinal position of the jetstreams which then alters total cloud quantities (and reflectance) so as to alter global albedo and thereby alter solar energy input to the oceans.

Francis & Vavrus have recently published interesting findings with regards the behaviour of the jetstream.

Here in Norway we have also had yet another storm system battering us on the edge of the jetstream that simply does nt seem to want to move.

«The sun causes latitudinal climate zone shifting with changes in the degree of jetstream zonality / meridionality by altering the ozone creation / destruction balance differentially at different heights above the tropopause.

The British Isles are not only tucked beside a vast Atlantic Ocean whose temperatures have a powerful effect on our weather, they are also at the receiving - end of the jetstream.

Not exact matches

However the company does not plan to launch the Vezel in India in the near term, as a smaller Brio - based SUV has received the green light to hit the jetstream of the Indian mini SUV market.

When you're flying thousands of feet in the air, the clouds in your jetstream, it can feel like the whole world is around you.

Currently the services and facilities of this location include: jetstream pool, spa, state of the art gym, 24 hour reception and weekly cleaning.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

That is because global warming, driven in part by the colossal fossil fuel consumption of today's massive global jetliner fleet, is expected to generate stronger wind shear within the stratospheric jetstreams.

Great visualization of the stuck deformed jetstream and the weather related incidents its causing everywhere.

Everything I say is a simple logical extrapolation from what should have been the obvious implications of that change in trend as regards jetstream behaviour.

Seems lately we have seen a stalling of regional weather systems moving across the N. Hem, causing an unusually shaped jetstream..

Poleward and / or more zonal jetstreams mean that the troposphere is bit warmer as the rate of energy flow through the troposphere increases.

And if the Northern Branch of the polar jetstream goes north, there is a fairly good chance that most winter storms (if they do in fact occur) will produce rain, sleet, mixed precip (that melts quickly).

This causes upwelling in the central Pacific — a lot of cloud near the dateline — and in this situation the Hadley Cell circulation distributes it into the mid latitudes and further north if the circumpolar jetstreams will allow it to (i.e. the winds aren't extending a long way south).

The whole reason the jetstream exists is because of the temperature difference between the Earth's equator and poles.

My own view is that the initiating mechanism is not small shifts in insolation hitting some kind of trigger related to snow albedo (the land - sea snow - ice area is relatively small compared to potential shifts in cloud amount and spatial distribution)-- rather it is shifts in global winds which likely relate to shifts in the jetstream (linked to...?

A new video describes the mechanics of the shifting jetstream through a presentation by Jennifer Francis with the Institute of Marine and Coastal Sciences at Rutgers University.

Similarly slowly evolving changes in the middle latitude jetstreams could potentially lead to marked changes in surface temperature and precipitation in regions that lie on the flanks of the storm tracks, such as southern Australia.

The poleward shift of the Southern Hemisphere middle latitude jetstream in response to increasing carbon dioxide is one of the most robust circulation responses found in climate change experiments, and is predicted to occur during all seasons (IPCC, 2007c).

Observational and numerical evidence of a poleward shift in the Southern Hemisphere middle latitude jetstream (a positive trend in the Southern Annular mode) in response to Antarctic ozone depletion (Gillett and Thompson, 2003; Arblaster and Meehl, 2006; Son et al., 2010; Polvani et al., 2011; McLandress et al., 2011; Thompson et al., 2011).

Opposite signed trends in the Southern Hemisphere middle latitude jetstream are expected in response to the recovery of the Antarctic ozone hole (Son et al., 2010; Arblaster et al., 2011; Polvani et al., 2011).

Temperatures often fluctuate in the Arctic due to the strength or weakness of the polar vortex, the circle of winds — including the jetstream — that help to deflect warmer air masses and keep the region cool.

But recent events and trends dealing with this type of wavy, snakelike jetstream are consistent with some of the latest science coming in.

So I will try to respond to any evidence that Brian offers that is pertinent to his argument of cause and effect but I will not feel compelled to be driven down blind alleys by jetstreams.

My feeling on the latter, is that solar magnetic cycles affect far - UV / stratospheric / jetstream patterns and the long - term heat storage of the oceans; and that the former shorter cycles may be a stochastic resonance phenomenon entrained in the long term pattern.

Shifting jetstream patterns, which have a strong influence on weather patterns in western Europe are one important component of a weather system, but only represent a change in climate if there is an apparently permanent shift north or south.
