Sentences with phrase «only by convection»

Have you read Dr Van Andel's paper «Note on the Miskolzci Theory» Energy & Environment Vol21 No4 2010 p277 - 292 Here is an exract «To summarize the main features of Miskolczi's theory: • The heat transfer from surface to atmosphere is only by convection, not by radiation.

You can ask Jennifer for my email address or I could send it via her (if she also want a copy) Heat transfer from the surface only by convection fits in with Nasif's, Wayne's and my observation that the radiant heat absorption by CO2 is insignificant.

Or can this sorting happen only by convection of masses of air?

Not exact matches

We played very well we did the hard work look it flamini was pulled by the neck that goal shouldn't have counted the second was a good delivery wish we could start scoring them corners their goal keeper made some very good saves we need to move the ball faster before it gets congested so far we only lost one match them goals will start to go in for us trust me as we are doing well we are just a little short in convection

«The water could only have risen from below, driven upward by powerful convection originating deep in the atmosphere.

«If Earth's core consisted only of iron, the free electrons in the iron could handle the heat transport by themselves, without the need for any convection currents,» says Karsten Held.

We describe the results with a hydrodynamic model that considers only convection of the particles by the cellular flow.

By comparison, conventional saunas must rely only on indirect means of heat: first, on convection (air currents) and then, conduction (direct contact of hot air with the skin) to produce its heating effect.

In other words, Lindzen's comments are only true for a system dominated by conduction, not for one in which atmospheric convection and ocean currents play such a large role.

The only way heat can escape to space is via radiation because space is a void and therefore heat can not be transmitted by convection or conduction.

(In real life I understand that mixing is the main agent of deeper warming in the ocean due to winds, currents, etc.) Only the top skin of water heats up and therefore lower warming must be by diffusion, or are convection cells within the water inevitable?

The only process that one could argue is minimally effected by CO2 is — the RATE of heat transfer from the Earth's surface — but with convective / conductive energy / mass transfer as the controlling mechanism — it would be immediately acted on by increased convection anyway — because Earth isn't surrounded by a glass bowl now is it — NO — just the cold depths of space!

At normal Earth temperatures heat loss is mostly by conduction and convection, radiation only dominates at much higher temperatures.

This is one of the more challenging aspects of modeling of the climate system because precipitation involves not only large - scale processes that are well - resolved by models but also small - scale process, such as convection, that must be parameterized in the current generation of global and regional climate models.

14), addresses the mechanisms of atmospheric heat transfer not only via radiation but also by convection, which is not mentioned once in the IPCC's scientific reports (Ref.

The implication that the upper troposphere loses energy only by one means (radiation) but receives energy by two means (radiation & convection) that would seem to increase with warming.

If the upper troposphere cools only by radiation (with probably some convection across the tropopause), but the surface transfers energy to the upper troposphere via radiation, convection, and evapotranspiration, why would the concurrent CO2 - induced warming be uniform?

Since it radiates both up and down, but is absorbing only from below (assuming no IR from above), then in the absence of additional heat transfer (by eg., conduction or convection), its absolute temperature would fall to ~ 0.84 Tsurface.

Adaptivity might enable better resolution of terrain, even starting to deal with convection by using finer grid only where convection was becoming significant.

The dynamics of the system are governed by the lapse rate which is «anchored» to the ground and whose variations are dependent not only on convection, latent heat changes and conduction but also radiative transfer.

The «unnatural» warming so far seen is however trended strongly to the alterations to the planetary surface by Humanity over the past 400 years and the rebalance towards greater kinetic induction (in its cumulative effect) is now producing observable alterations not only to the Land Surface median Temperature, but to the Ocean (vie conduction / convection) and a still unconfirmed claim of a small overall rise in Median Atmospheric Temperature, which if «true» would place the Planetary Biosphere on the «Human Population Plot» with regard to «warming».

«The authors demonstrate that model estimates of climate sensitivity can be strongly affected by the manner through which cumulus cloud condensate is converted into precipitation in a model's convection parameterization, processes that are only crudely accounted for in GCMs.

They've substituted empty space populated by «ideal gas», without volume, attraction, weight, not subject to gravity so they have no convection, only radiation.

The ocean can rapidly transport heat up through itself by convection and only slowly transport heat down by conduction.

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.

Since an inversion will usually control the upper level to which heat is carried by convection, only a shallow layer of air will be heated if the inversion is low and large, and the rise in temperature will be great.

Without a wind or convection to mix the air, the only way water vapor escapes from near the ocean - air interface is by diffusion, which is very slow.

(For the earth system as a whole, the only way it can lose heat is via radiation, although heat can be transferred between different parts of the system, e.g., surface to atmosphere by convection and evaporation / condensation.)

Yes, a glass greenhouse works by restricting convection, and the fact that glass passes shortwave radiation and not longwave makes only a minor contribution.

To my way of thinking «atmospheric heat can only be trapped, or slowed down, by a reduction in convection.

So the energy absorbed from the sun at depth must find its way to the surface by some means other than radiative which of course leaves only convection and conduction.

You are confused: Saying we are solving for the radiative imbalance at the top - of - the - atmosphere doesn't mean that we are only interested in the temperature there... What it means is that we can use that value, along with the fact that the lapse rate in the troposphere will be determined mainly by convection to figure out what will happen at the surface most easily.

For example, as one critic pointed out immediately, he only calculated how heat would be shuttled through the atmosphere by radiation, ignoring the crucial energy transport by convection as heated air rose from the surface (this deficiency would haunt greenhouse calculations through the next quarter - century).

Or it may be that as an instantaneous solution to radiative transfer, HITRAN is ok, but to the question of non-instantaneous energy transfer from the surface to the TOA which necessarily includes convection and transfer of energy by latent heat of vaporisation and more... then it only tells part of the story.
