Temperature gradient

The temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location. It is normally negative in the lower atmosphere; that is, the temperature decreases with height under normal atmospheric conditions.

In physics, the temperature gradient is a physical quantity used to describe the direction and intensity of temperature changes. Formally, it is a vector field defined as the gradient field of a scalar field, which is precisely the “temperature field”.

The temperature gradient is a dimensional quantity expressed in units of degrees (on a particular temperature scale) per unit length. The SI unit is kelvin per meter (K/m).
