Sentences with phrase «air convection»
Air convection refers to the process of heat transfer in which air circulates, typically due to differences in temperature. Hot air rises because it becomes less dense, while cold air sinks as it becomes denser. This movement of air creates a convection current, leading to the circulation and mixing of the air within a space. Full definition
For example, we expect greater moist air convection from the tropics with increased temperature.

Reduced moisture during the summer will imply a reduction in moist air convection at the land's surface.
The cooling effect by air convection can surpass considerably the warming effect of radiation.
This physical system (multiple cells of air convection) acts in the Earth's troposphere like a continuous surface cooler.
It is a simple fact that if you decrease the amount of free air convection the heater will assume a higher temperature, that is why they install safeguards so your house does not burn down if you shove your sofa against an electric baseboard heater.
Over ocean stretches with a positive SST anomaly air convection is higher (as the temperature difference between the warm sea surface and the cool air higher up in the troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.
This air will be heated as it passes over the tarmac and will be forced up the convection shaft by a combination of wind power and heated - air convection forces.
Greg, with respect, the example system I described was a simple electric heater depending on free air convection to determine the nominal operating temperature.
Figure 1: The simplified Lorenz phase space equations of air convection (top) and some numerical solutions (below, separated for clarity).
After all, what causes nights to warm more quickly than days as the result of enhanced greenhouse effect is the greater dependence of night - time heat loss upon thermal radiation rather than the moist air convection that dominates during the day.
Well, technically it isn't a hotspot but a region in the tropical mid-troposphere where temperatures rise more rapidly than the surface due to increased moist air convection that plays a stronger role in the transfer of heat in the tropics.
Question is, how much heat is removed from the surface by radiation, air convection and evaporative cooling.
The surface and lower troposphere loses much of its heat due to moist air convection, but given that the stratosphere is extremely dry, the loss of heat in the upper troposophere must be due to something else: outgoing longwave radiation, I would presume.
The Air convection systems uses an innovative fan that rotates one way, then reverses direction to allow heated air to circulate evenly around whatever you may be cooking.
