Sentences with phrase «temperature gradient occurs»

Not exact matches

In the first test of its kind, researchers watched the «ion temperature gradient» (IGT) which occurs from the cool edge of the plasma to its hot center and that may affect the ability of the plasma to reach the temperature at which fusion takes place.

Convection is a more efficient mode for carrying energy than radiation, but it will only occur under conditions that create a steep temperature gradient.

(PS diffusion of matter and energy (latent heat) during such phase changes requires compositional and temperature gradients — entropy must then be produced, so there is a departure from actually being adiabatic — a smaller departure if pressure is being changed less rapidly (so that diffusions occur across smaller gradients).

Temperature gradients are generally (see next paragraph) required to drive these flows of heat (continually through layers with convection / conduction / diffusion driven by differential heating, on the scale of distances from emission to absorption for radiant flows), so the temperature tends to decline from where solar heating occurs to where heat escapeTemperature gradients are generally (see next paragraph) required to drive these flows of heat (continually through layers with convection / conduction / diffusion driven by differential heating, on the scale of distances from emission to absorption for radiant flows), so the temperature tends to decline from where solar heating occurs to where heat escapetemperature tends to decline from where solar heating occurs to where heat escapes to space.

This occurred as the inter-tropical convergence zone (ITCZ) moved north as a result of a higher temperature gradient (some 0.5 °C) caused by a stronger THC.

Hence, if David and the IPCC etc wish to put forward ideas that ignore basic physics, meaning that they ignore the maximum entropy production which the Second Law says will tend to occur, thus establishing a stable temperature gradient which, as Big Wave Dave said, «obviates the need for concern over GH gases,» then the onus is on them to prove what they say, not only with valid physics, but also empirical evidence, experiments and studies, as appropriate and as is usually done in physics.

Whether or not it will occur depends on the actual vertical temperature gradient and how this gradient compares to the lapse rate.

The existence of the temperature gradient is explained by the way heat is transferred: within the bulk waters, heat transfer occurs due to turbulence, but as the surface is approached, viscous forces dominate and molecular processes prevail.

You may have noticed that these events occurred during springtime, which is typically when the greatest temperature gradients can occur.

The latitudinal temperature gradient in summer is much smaller, thus providing less drive for exchange of air masses between middle latitudes and polar regions — and when exchange occurs the effect on temperature is less than that caused by a winter «polar express» of Arctic (or Antarctic) air delivered to middle latitudes.

Eli - If temperature gradients were larger (as might occur with zero greenhouse gases) then natural convection will tend to be higher.

Rather than focusing on temperature gradients, which are often a consequence rather than cause of the circulation, one should investigate the conditions when condensation is likely to occur to predict changes in atmospheric circulation.
