Antarctic where surface temperatures drop to approximately −98 °C (−144 °F; 175 K). Due to the very strong temperature gradient near the surface, these...

{\displaystyle \nabla T} is the temperature gradient. The Seebeck coefficients generally vary as function of temperature and depend strongly on the composition...

For instance, the thermal wind associated with pole-to-equator temperature gradients is the primary physical explanation for the jet stream in the upper...

adiabatic lapse rate. Under the right conditions, the normal vertical temperature gradient is inverted so that the air is colder near the surface of the Earth...

In atmospheric science, the weak temperature gradient approximation (WTG) is a theoretical framework used to simplify the equations governing tropical...

sophisticated variants of sublimation apparatus include those that apply a temperature gradient so as to allow for controlled recrystallization of different fractions...

thermophoresis, the directed movement of particles in a microscopic temperature gradient. Any change of the chemical microenvironment of the fluorescent probe...

wind gradient, more specifically wind speed gradient or wind velocity gradient, or alternatively shear wind, is the vertical component of the gradient of...

until the following morning when the cycle repeats. A land/sea temperature-pressure gradient is not always necessary to drive the marine layer and low clouds...

thermal gradient formed between two different conductors can produce electricity. At the heart of the thermoelectric effect is that a temperature gradient in...

change the way it conducts heat. Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is...

base of the convection zone. In a radiative zone, the temperature gradient—the change in temperature (T) as a function of radius (r)—is given by: d T ( r...

Lapse rate corresponds to the vertical component of the spatial gradient of temperature. Although this concept is most often applied to the Earth's troposphere...

causes the temperature on the surface of the clothing to be less than the temperature on the surface of the skin. This smaller temperature gradient between...

variables of heating, which include material types and constraints. Temperature gradients, thermal expansion or contraction and thermal shocks are things...

the gas is stimulated either mechanically or (less preferred) by a temperature gradient between the top and bottom of the rotor. With a countercurrent-to-feed...

This unusual arrangement is called a temperature inversion. During the daytime, the normal temperature gradient of the atmosphere is cold air above warm...

the thermal conductivity, and ∇ T {\displaystyle \nabla T} is the temperature gradient. This is known as Fourier's law for heat conduction. Although commonly...

a temperature gradient, so the measured temperature is different from the actual temperature of the system. In such a case the measured temperature will...

device that measures temperature (the hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space). A thermometer...

has passed for all permanent temperature gradients to establish themselves in space, after which these spatial gradients no longer change in time (as...

non-equilibrium processes, it is desired to consider the effect of a temperature gradient established by the surroundings across the system of interest when...

temperature gradient in the snow, because the ground temperature at the base of the snowpack is usually around 0 °C, and the ambient air temperature can...
