Sentences with phrase «air advection»
Air advection refers to the movement of air horizontally in the atmosphere. It is when air flows from one place to another, carrying with it properties like temperature, humidity, and pollution. It plays a crucial role in the weather, affecting how heat and moisture are distributed around the Earth. Full definition
However, at latitudes poleward of 40 ° in winter, positive correlations dominate as the water - holding capacity of the atmosphere limits precipitation amounts in cold conditions and warm air advection in cyclonic storms is accompanied by precipitation.

The difference is that the warming of the Western Antarctica Peninsula was known and is easily explained through atmospheric circulation dynamics — regional warm air advection patterns.
Therefore and in flagrant contradiction with Steig et al. 2009, catabatic winds and anticyclones coming out of Antarctica are stronger - in fact more snow precipitation there - thus regional warm air advections directed by the relief will also be stronger.
Perhaps taking the time to familiarize oneself with the atmospheric circulation patterns of the area will show that it is perfectly normal, natural and expected that those particles reach Antarctica through warm air advection pathways... Just look at a satellite animation.
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.
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).
Strong maritime - air advection in 1990 resulted thus in FOR reduced by 0.079, effect by two orders - of - magnitude stronger than the decrease effected by the per - decade increase in CO2.
I don't have the article handy, but my recollection is that anomalous meridional flow during this time period led to warm air advection into the arctic (and compensatory cold air advection into the mid-latitudes) which would have ameliorated some of the cooling.
Otterman, J., R. Atlas, G.L. Russell, and H. Saaroni, 2003: Impact on regional winter climate by CO2 increases vs. by maritime - air advection.
