A 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. The temperature spatial gradient is a vector quantity with dimension of temperature difference per unit length. The SI unit is kelvin per meter (K/m). Temperature gradients in the atmosphere are important in the atmospheric sciences (meteorology, climatology and related fields). A temperature gradiometer or thermal gradiometer is a scientific instrument (a gradiometer) for measuring temperature gradients.

T=T(x,y,z) where x, y and z are the coordinates of the location of interest, then the temperature gradient is the vector quantity defined as \nabla T = \begin{pmatrix} {\frac{\partial T}{\partial x}}, {\frac{\partial T}{\partial y}}, {\frac{\partial T}{\partial z}} \end{pmatrix} ==External links== IPCC Third Assessment Report Pictorial Representation of Temperature Gradient (Tools). fr:Gradient#Gradient de température
