Sentences with phrase «air over the continent»

The warmer ocean waters mean more moisture in the atmosphere for the storm to suck up; the cold air over the continent ensures that moisture falls as snow.

Some powerful computer simulations of Earth's climate, including several analyzed by Hoerling and his team, also fail to show the pattern of warm air over the Arctic and cold air over a continent.

I can literally trace on a map the position of the jet stream with a 700 or 500 mb charts, especially by being fully aware that over North Pacific and Atlantic cyclones the jet stream can be to the south of them, all while following the interface between coldest polar and temperate air over the continents.

Not exact matches

«We have found that the measures to reduce methane and other ozone precursors would significantly improve the ozone air quality, especially over northern continents.

First, as pointed out by Masters, there was a big loop in the jet stream over the continent, funnelling warm air northwards from the Gulf of Mexico.

Daniel Rosenfield and his colleagues at the Hebrew University of Jerusalem studied satellite data of air masses over the Indian Ocean, which contain large numbers of air pollution particles blown off the surrounding continents.

In late 2010 and early 2011, the continent Down Under received about twice its normal complement of rain, thanks in large part to unusually warm sea - surface temperatures just north of Australia and a particularly strong La Niña — in essence, combining a source of warm humid air with the weather patterns that steered the moisture over the continent where it condensed and fell as precipitation.

Delta Air Lines serves over 300 destinations in 59 countries on six continents.

In the Antarctic ozone depletion causes changes in air pressure that strengthen wind circulation and the winds maintain a cooling effect over the Antarctic continent.

As a consequence, cold air from the North American continent traveled farther over ice, instead of warmer ocean waters, remaining cold until it hit warmer open water in the middle of Labrador Sea.

The sea ice in the Siberian Arctic is peaking, its effect on the meridional temperature gradient strong, promoting increased zonal flow of large - scale winds, which advect warm air and moisture over the Eurasian continent from the Atlantic and disrupt vertical stratification near the surface and promote high cloudiness, both of which lead to increasing temperatures — greatest at low altitudes and high latitudes.

A subtropical belt of high pressure that flows over the continent regularly delivers pulses of hot, dry air to the surface in the summer.

Hot north pole: the cold polar air has shifted over to us on the eurasian continent.

During the winter months in middle and high latitudes, the lower parts of the troposphere over continents often serve as reservoirs of cold air as heat is radiated into space throughout the long nights.

The concentration of cloud condensation nuclei in the lower troposphere at a supersaturation of 1 percent ranges from around 100 per cubic centimetre (approximately 1,600 per cubic inch) in size in oceanic air to 500 per cubic centimetre (8,000 per cubic inch) in the atmosphere over a continent.

Owing to the enhanced descent of air over the eastern parts of the oceans, landmasses adjacent to these areas (typically the western sides of continents) tend to be deserts, such as those found in northwestern and southwestern Africa and along western coastal Mexico.

The subsiding air warms by compression and, coupled with cooling of the lowest layers overlying the cold ocean currents normally found off the west coasts of the continents, forms a pronounced temperature inversion (warm air over cold), called the trade - wind inversion.

A warmer stratosphere would in turn affect air circulation patterns that currently keep cold air trapped over the continent.

Subsidence inversions are common over the northern continents in winter and over the subtropical oceans; these regions generally have subsiding air because they are located under large high - pressure centres.

As North America is the only broad continent that stretches from high to low latitudes without an east - west mountain chain, the intersections of cold and hot air masses will continue to occur over the U.S. and Canada meaning severe weather will continue and will likely intensify as warming occurs.

So, it takes heat to evaporate the moisture from the oceans, and it generally stays warmer near the oceans, but once this moist air travels over the interior of a continent and finds cooler air, bingo, you get more snow!
