Sentences with phrase «air parcels below»

Higher pressure increases the temperature of air parcels below.

Not exact matches

In nature, the dry adiabatic lapse rate of air in the atmosphere is maintained because the system is differentially heated from below causing parcels of air to constantly move up and down.

Evaporation injects potential energy into an air parcel in the form of latent heat thereby reducing density and weight to below the global average.

At the surface, increased pressure from injecting water vapour into a parcel of air via evaporation causes the parcel to rise so that surface pressure below it falls.

ii) If pressure within an air parcel rises then the contents expand to occupy a larger space but that decreases density and weight which reduces pressure at the surface below.

Evaporation initially reduces the density of the air within a convective cell below the global average and condensation simply restores the density within the cell to the global average so it is trite to suggest that the condensation process additionally reduces density and surface pressure outside the parcel.

If the environmental lapse rate is larger than the dry adiabatic lapse rate, it has a superadiabatic lapse rate, the air is absolutely unstable — a parcel of air will gain buoyancy as it rises both below and above the lifting condensation level or convective condensation level.
