Sentences with phrase «average the energy transferred»

If the atmosphere is warmer than the liquid, on average the energy transferred to the liquid by water molecules being absorbed will excede the energy transfer to the atmosphere by evaporation.

Not exact matches

While many basic aspects of physics can be included (conservation of mass, energy etc.), many need to be approximated for reasons of efficiency or resolutions (i.e. the equations of motion need estimates of sub-gridscale turbulent effects, radiative transfer codes approximate the line - by - line calculations using band averaging), and still others are only known empirically (the formula for how fast clouds turn to rain for instance).

The processes (absorption of light, collisional energy transfer and emission) can be separated because the average time that an isolated CO2 molecule takes before it emits a photon is much longer that the time for collisional de-excitation (~ tens of microseconds at atmospheric pressure, less, higher in the atmosphere).

Do these molecules cool down — transfer energy to cooler oxygen and nitrogen molecules — and then absorb photons to complete the average warming of the atmosphere?

Temp will peak when the net energy transfer goes below average and not when the solar input goes below average.

The average position of the ITCZ is situated north of the equator because most ocean is in the southern hemisphere and it is ocean temperatures that dictate its position by governing the rate of energy transfer from oceans to air.

If the average radiant layer were 288K @ 390Wm - 2 and you didn't have to consider other non-radiant means of energy transfer, that would be a fair estimate.

The net heat flows are much smaller like 60 W / m ^ 2 which is a typical estimate for the average net energy transfer from Earth surface due to LWIR taking both emission and absorption into account.

I also claim that because the atmosphere is on average colder than the surface, more energy is transferred from the surface to the atmosphere compared with the reverse situation.

Other than redistribution or averaging velocity of molecules, air only transfers energy thru air via convection.

Since the infrared - inactive gases don't emit infrared light, if enough absorbed energy is transferred to the nitrogen and oxygen molecules through collisions, that could theoretically increase the average energy of the air molecules, i.e., it could «heat up» the air.

Since the average land temperature is lower and dryer than the SST, warming and cooling anomalies are larger for a given amount of energy transfer from the oceans, latent and sensible.

To be energy or more properly, heat transferred, the one - way upwelling radiation from the surface absorbed by the air should be reduced by subtraction of the down - welling radiation of the air absorbed by the surface Note that by subtraction of the (about 20 W / m ² in global average) flow surface to cosmos of both terms of GH, GH expression becomes GH = (radiation from the surface absorbed by the air) minus (outgoing longwave radiation from the air) which has absolutely no physical sense!

Due to this loss of energy, the temperature of the remain water has dropped (1 / heat capacity = 0.24 degK / (kJ / kg)-RRB- OR the lost energy must be imported by: conduction (collisions transferring kinetic energy), convection (a new group of molecules with a new average energy), or absorbing radiation.

On the average, the evaporation transfers about 45 kJ / mol of energy from the liquid phase to the gas phase at 20 degC (and 40.65 kJ / mol at 100 degC).

You can have a long period of cold air at the surface with little turbulent mixing and little energy transfer, followed by a short period of a warm surface and lots of turbulence and energy transfer - ending with a time average of warm over cold, but a time average of upward energy transfer.

Although it is a reasonable simplification to think of the transfer of thermal energy in a conduction - like model - where flux is related to the temperature gradient using a turbulent transfer coefficient - it is quite possible to have time - averaged flux moving in the opposite direction to time - averaged temperature gradient.

# 5) On the average the atmosphere is homogeneous and any component of energy transfer (components of a vector) horizontally is totally cancelable and can be reasonably considered zero at the local macro level.

Of course, if you average enough collisions, the net flow of energy is from the warm to the cold block, but individual collisions can transfer energy either way.

This is not a violation of the 2nd law, because there is, on average, a NET transfer of energy from the warm metal to the cooler water.

While A is transferring energy to B, B is transferring a similar amount of energy to A. Ie the NET transfer of energy is zero (at least when averaged over sufficiently long periods of time to average out short - term statistical fluctuations).

Rather than rely on miners to verify transactions, any average user running a Raspberry Pi can now be able to open a channel and enable transfer of funds for a fraction of the previous cost while also consuming little energy.
