Sentences with phrase «warm air masses around»

The polar jet streams are narrow, fast - flowing rivers of wind high in the Earth's atmosphere that push cold and warm air masses around, playing an important role in determining the weather.

Not exact matches

If a larger mass of warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange surface play an important part) from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).

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.

My curiosity is built around the assumption that the warmer air mass must have transferred heat to the ocean (warmer to colder) and that raises the thought that the atmosphere would have to get colder than the ocean for it (the air) to be warmed by the sea.

While colder and warmer air masses are shifting around, cold air and warm are being «produced» at certain rates that globally averaged may not shift around quite so much.
