Sentences with phrase «changes in jet stream position»

Solar has its largest influence in the lower stratosphere (including changes in jet stream position), CO2 in the lower troposphere.

Probably by changes in jet stream position, due to changes in UV absorption in the stratosphere.

Not exact matches

Widening of the tropics would also probably be associated with poleward movement of major extratropical climate zones due to changes in the position of jet streams, storm tracks, mean position of high and low pressure systems, and associated precipitation regimes.

Dr Screen said: «The results of the computer model suggest that melting Arctic sea ice causes a change in the position of the jet stream and this could help to explain the recent wet summers we have seen.

Importantly, the NAO relates to changes in the strength and position of the North Atlantic jet stream - a band of very fast winds high in the atmosphere.

Or it may be caused by any other mechanism (like the influence of solar changes on the jet stream position) which enhance the simple direct insolation change which is incorporated in several current climate models...

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.

So jet stream positioning and consequent changes in solar input to the oceans could swing the ENSO phenomenon in favour of dominant El Nino or dominant La Nina subject additionally to possible modulation from internal oceanic effects.

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.

«Changes in the position of the jet stream are very noisy, and can be hard to detect even in climate simulations,» Amy Butler, an atmospheric scientist at NOAA, told BuzzFeed News.

Indeed on the basis of my previous article about weather being the key it may be possible to get even earlier warning of changes in global temperature trend from observation of the preferred positions of the jet streams and the main high pressure systems.

I have now realised that the global albedo changes necessary and the changes in solar energy input to the oceans can be explained by the latitudinal shifts (beyond normal seasonal variation) of all the air circulation systems and in particular the net latitudinal positions of the three main cloud bands namely the two generated by the mid latitude jet streams plus the Inter Tropical Convergence Zone (ITCZ).

On the other side, more UV from the sun has its main effect in the stratosphere, changing the jet stream position, and downward further penetrating / warming the oceans to deeper layers.
