Geothermal gradient is the rate of change in temperature with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises...

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...

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

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...

{\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...

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...

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...

which the temperature rises most quickly, moving away from (x, y, z). The magnitude of the gradient will determine how fast the temperature rises in that...

the amount of atmospheric refraction is a function of the temperature gradient, temperature, pressure, and humidity (the amount of water vapor, which...

temperature inversion. During daytime, the normal temperature gradient of the atmosphere is cold air above warm air. Passing through the temperature inversion...

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