Sentences with phrase «air masses»

"Air masses" refers to large bodies of air that have similar temperature and humidity characteristics. They can form over specific regions and move across the Earth's surface, affecting the weather in different areas. Full definition
This is primarily a consequence of weather, controlled by the rising and sinking of air masses.
If the jet stream dips south, for example, it takes the colder air masses with it.
Think of a large hot air mass in the atmosphere as rising like a hot air balloon in the shape of a mushroom cloud -LRB-!).
So the whole rising air mass experiences less cooling than it would in a dry atmosphere.
If it goes south, it causes a spell of cold weather; if it goes north, it brings warm air masses with a lot of precipitation in the winter.
Cloud cover reduces the earth's ability to release heat and during the colder season, clouds are typically associated with warm, moist air masses that promote warm temperatures.
A cold air mass flowing away from its source region over a warmer surface will be warmed from below making the air more unstable in the lowest layers.
The boundary between two different air masses where warm air pushes cold air away to bring warmer weather.
This is a great teaching resource for air mass characteristics.
The goal was to reach the desired flexibility of valve opening schedule air mass control on a cylinder - by - cylinder and stroke - by - stroke basis.
These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns.
Work then will also focus on studying to what extent chlorine - activated and ozone - depleted air masses will make its way into the densely populated middle latitudes.
It would also require us to estimate the total air mass assumed to be associated with each discrete point and time where we have a temperature reading.
Both of these sensors have to do with sending air mass and pressure information to the engine computer.
If we look at the temperature profiles of the previous example, the effects of warming and cooling on the respective air masses are very different.
Massive air mass manipulation is also accomplished with engineered high and low pressure zones.
A front is the boundary between two different types of air mass.
The polar air masses are getting colder and expanding, contrary to expectations.
The boundary between two different air masses where the cold air pushes the warm air out of way and brings colder weather.
A warm air mass moving over a cooler surface is cooled from below and becomes stable in the lowest layers.
Circulation fields for May through June resulted in hot air masses from south Asia and Africa entering Siberia and the Russian Arctic, as well as increasing sea surface temperatures (SSTs) in the North - East Atlantic domain, subjecting the relatively thin ice cover to rapid melting.
As the oceans continue to warm, cold Arctic air masses collide with increasingly warm Atlantic Ocean waters.
The mean mass of water vapor is estimated as 1.27 × 1016 kg and the dry air mass as 5.1352
More meridonal jet stream tracks flowing around the world between the climate zones result in longer lines of air mass mixing at climate zone boundaries.
25 Weather Fronts A weather front is simply a boundary between air masses.
Small changes in ocean heat transport have a bigger effect for the atmosphere than for the deep ocean, because there is much more water beneath 300 meters, than water and air mass above it.
This ridge is responsible for steering the wet tropical air masses away from California.
Moving with the flow, they often use the momentum and direction of moving air mass and sea waves to gently steer their vessels into narrow slips.
The ocean as a whole is warming; however, coastal upwelling may ultimately be enhanced by alongshore winds, which strengthen in proportion to the temperature contrast between the oceanic and continental air masses [Sydeman et al., 2014].
The heating of air masses over tropical Asia in summer initiates a low - pressure system, which becomes the focal point of the trade winds of both hemispheres.
This allows the lower pressure and very cold arctic air mass to expand further south, chilling everything well down to Scotland.
If air masses rose adiabatically, there wouldn't be lightning and thunder.
Hot air masses from South Asia and Africa now sit over Siberia and the Russian Arctic (Pokrovsky) and in the first part of July low pressure has become more dominant in the central Arctic Ocean, which could set up northward drift along with warm air transport in the East Siberian and Laptev Seas (Maslanik).
The large snowfall events in Boulder were not associated with cold temperatures, but instead with especially moisture - laden air masses passing through the region.
But the idea that a lack of sea ice sends swirling air masses south and smacks us with horrid, frigid winters has stirred controversy in climate science.
One probably unanswered question is — how much energy is exchanged across the tropopause through air mass exchange?
The water vapor in the cooling air mass condenses and rains, and rains and rains all over the equator in the Tropical zones.
