Sentence examples for parcel of air from inspiring English sources
The total motion of a parcel of air has two parts: (1) the motion relative to Earth as if the planet were fixed, and (2) the motion given to the parcel of air by the planet's rotation.
He forms a little parcel of air with his hands and moves it to a distant corner of his desk.
Cumuliform clouds will form in the free atmosphere if a parcel of air, upon saturation, is warmer than the surrounding ambient atmosphere.
In this situation, since the environmental lapse rate is greater than the adiabatic lapse rate, an ascending parcel of air remains warmer than the surrounding ambient air even though the parcel is both cooling and expanding.
The dv of a parcel of air changes, however, with temperature or pressure even though no water is added or removed, because, as the gas equation states, the volume V increases with the absolute, or Kelvin, temperature and decreases with the pressure.
The microscopic particles of atmospheric dust, sea salt and smoke known as aerosols are meteorological and climatic will-o'-the-wisps -- now here, now not, materializing somewhat randomly in a given parcel of air and then disappearing in a few days.
Cumulonimbus clouds routinely form in the tropics where rising parcels of air are warmer than the surrounding ambient atmosphere.
LBM evolved from the numerical fluid modeling technique Lattice Gas Automata (LGA), in which parcels of air adhere to microscopic laws which dictate their movement.
Earth's rotation makes these disturbances spin by means of the Coriolis effect, an apparent deflection of moving parcels of air that forces storms to whirl counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
For the analogous reduction in terms of pressure values, GPT2 reverts to the virtual temperature (i.e., the temperature at which a parcel of dry air would have the same pressure and density as the equivalent parcel of moist air).
Once upward air motions are initiated in an unstable atmosphere, rising parcels of warm air accelerate as they rise through their cooler surroundings because they have a lower density and are more buoyant.
