Sentences with phrase «term changes in atmospheric circulation»

Long - term changes in atmospheric circulation have resulted in an increased amount of perennial sea ice being exported through Fram Strait rather than being recirculated (e.g., Beaufort Gyre); this was what set up the 2007 record September minimum.

Not exact matches

Only 10 % of the long - term LOD variation can be explained by the observable changes in atmospheric circulation.

A shift in atmospheric circulation in response to changes in solar activity is broadly consistent with atmospheric circulation patterns in long - term climate model simulations, and in reanalysis data that assimilate observations from recent solar minima into a climate model.

Clouds change — associated with changes in ocean and atmospheric circulation — in the short term and radically change the energy budget.

LONDON, 17 March, 2017 — Scientists have calculated that at least 30 % and perhaps one half of the decline in Arctic summer sea ice could be attributed to natural causes — changes of ocean and atmospheric circulation that happen according to some long - term cycle.

In both the tropics and extratropics, it is difficult to discern significant long - term trends in the patterns of climate variability from natural variability, never mind abrupt (threshold) changes in the atmospheric circulatioIn both the tropics and extratropics, it is difficult to discern significant long - term trends in the patterns of climate variability from natural variability, never mind abrupt (threshold) changes in the atmospheric circulatioin the patterns of climate variability from natural variability, never mind abrupt (threshold) changes in the atmospheric circulatioin the atmospheric circulation.

Thus an understanding of the mechanisms distributing water vapor through the atmosphere and of water vapor's effects on atmospheric radiation and circulation is vital to estimating long - term changes in climate.

While on first thought this might seem undesirable because we are looking for a global number, it might make sense to separate them due to the large difference in land / ocean ratio and the fact that atmospheric circulation patterns isolate them WRT shorter term changes.

In summary, it seems to me that in his evidence, Hansen has only addressed changes in the distribution of continents in terms of albedo effects, rather than oceanic and atmospheric circulatioIn summary, it seems to me that in his evidence, Hansen has only addressed changes in the distribution of continents in terms of albedo effects, rather than oceanic and atmospheric circulatioin his evidence, Hansen has only addressed changes in the distribution of continents in terms of albedo effects, rather than oceanic and atmospheric circulatioin the distribution of continents in terms of albedo effects, rather than oceanic and atmospheric circulatioin terms of albedo effects, rather than oceanic and atmospheric circulation.
