Sentences with phrase «moist parcel»

As a moist parcel of air ascends it cools as it expands and does work against the rest of the atmosphere.

Why would the moist parcel be surrounded by dry air?

I was asking why a moist parcel of air would be surrounded by dry air.

Perhaps you mean to say that moist convection enforces a shallower lapse rate than dry convection, because otherwise moist parcels become bouyant.

«Perhaps you mean to say that moist convection enforces a shallower lapse rate than dry convection, because otherwise moist parcels become buoyant.»

Not exact matches

The cake is really moist and gives his whole aroma when it is parceling the mouth.

Namely these factors are CAPE, which is Convective Available Potential Energy, which is the maximum amount of energy that a rising parcel (which [is] an arbitrary amount of mass) can have as it's rising through the atmosphere; wind shear, which is the difference in wind [vectors] at the top and bottom of the atmosphere; and specific humidity, which is the ratio of water to the total mass of a moist system.

A low - altitude flow of warm, moist air from an ocean area combined with a flow of cold, dry polar air high up creates maximum instability, which means that parcels of air heated near the surface rise rapidly, creating powerful updrafts.

For reference, the amplification is related to the sensitivity of the moist adiabat to increasing surface temperatures (air parcels saturated in water vapour move up because of convection where the water vapour condenses and releases heat in a predictable way).

Nullius: «A parcel of moist air will rise if it is moister than the air surrounding it — but why would it be?

Specific humidity is the total mass of water vapor in a parcel of air divided by the mass of the moist air.

If there is a mean rate of 6.5 K / km, the parcel that ascends moist adiabatically will be warmer than the environment.

Second, the effects of changing density and latent heat release in the process that you describe (of a one - dimensional ascent of a moist air parcel) are well - known and discussed in Section 3.4 in our paper «Comparing forces due to condensation and buoyancy».

In simple words, in order to lift a moist air parcel, you must draw a dry air parcel down: this is what circulation is about.

My comprehension is that a rising moist air parcel reduces in temperature and volume gradually, but condensation occurs rather abrupt when the air parcel temperature reaches the dew point.

where is the gravitational acceleration, is the net radiative energy input to the atmosphere, is the ocean heat uptake, is the north - south wind, and is the energy of an air parcel (specifically the moist static energy).

Anastassia and co-authors, it comes down to whether you believe undilute ascending air parcels follow the moist adiabat which requires latent heat release in its derivation from the thermodynamical equations.
