Sentences with phrase «air advection in»

Not exact matches

Arctic winter formation has been largely hit by advection from cyclones easily punching through what was once a mighty fortress of cold air living in a physical symbiosis with much thicker sea ice.

The troposphere is not everywhere at all times locally vertically coupled by convection; in particular, at night and at high latitudes, especially in winter, and where there is warm air advection aloft, some layer of air can become stable to localized convection.

The air temperature patterns were a result of low pressure on the Eurasian side of the Arctic (Figure 8), along with high pressure in the Bering Sea, which supported some warm air advection into the Chukchi and East Siberian seas region.

In fact, if you look at my posting below you can actually see this «warm moist air advection» from the Pacific taking place as we speak!

Synoptic conditions with the positive phase tend to consist of increased southerly flow and warm air advection into Alaska during the winter, resulting in positive temperature anomalies.

The same can be observed around some Andean glaciers and of course the Antarctic peninsula: renewed advection of warmer air displaced by colder HP polar air masses descending to lower latitudes can melt certain regions yet it does not mean global warming, quite the opposite in fact.

With regard to summer meteorological forcing, 2007 was dominated by a strong dipole pattern in sea level pressure (SLP), with high pressure over the Beaufort Sea and winds blowing from the Bering Strait across the North Pole, promoting both advection of warm air and compaction of the ice pack.

Richard, as I pointed out elsewhere in this thread, the ozone hole facilitates cooling in the southern polar region while the circumpolar vortex block warm air advection from the north.

Likewise, the cooling in the South Pacific Sector over the Ross Sea Ice edge and to the north of it (Fig. 3) corresponds with the northern side of the negative geopotential height trend evident in NCEP2 that implies anomalous equatorward advection of cold air.

With upcoming warm air advection event in #Arctic, keep an eye on this surface air temperature plot (modified from https://t.co/qm5ObvNzL5) pic.twitter.com / b6udPRpyey

June was warmer than average more widely over the Arctic Ocean (Figure 4b); the month saw a weather pattern similar to the Arctic Dipole, in which higher than average pressure over the American side of the Arctic drives warm air advection from the Pacific (Figure 4c).

-- It seems perfectly reasonable to me that if we imagine the surface never emits that energy in the first place, - energy that is stored in the surface and just below, i.e. oceans, lakes, rivers, ground, and air, — just to mention a few, then any surface temperature change would be completely reliant on variations in Solar irradiation and advection mainly by Water Vapor (WV) but also by other GHGs that have the ability to contain more heat than the rest of the atmospheric gases.

back to the horizontal gradient, if the upper tropospheric thermal wind shear increase is greater than the decrease of the lower layer, then maybe the overall baroclinic instability would be stronger — but currently the upper level eddy circulations do not transport much heat poleward, so would the structure of cyclones change so that a deeper layer of air is involved in the thermal advection, compensating for a weaker temperature gradient?

The advection of warmer air and warmer water plays a big role in Earth's climate.

In the Arctic we benifit from warm air advection every day of the year.

You can freeze in the Sahara when it is winter time & you have cold air advection blowing in colder air (and some snow for effect); --RRB-

In August, higher pressure rebuilt in the Beaufort Sea together with low SLP over Siberia, helping to compact the ice towards the pole and leading to advection of warm, southerly air into the ArctiIn August, higher pressure rebuilt in the Beaufort Sea together with low SLP over Siberia, helping to compact the ice towards the pole and leading to advection of warm, southerly air into the Arctiin the Beaufort Sea together with low SLP over Siberia, helping to compact the ice towards the pole and leading to advection of warm, southerly air into the Arctic.
