Middle latitudes Middle latitudes The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) of Earth lie between 23°26'22" and 66°33'39" north, and between 23°26'22" and 66°33'39" south. They include Earth's subtropical and temperate zones, which lie between the tropics and the polar circles (between the Tropic of Cancer and the Arctic Circle, and between the Tropic of Capricorn and the Antarctic Circle). Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones, which have traveled from their areas of formation closer to the Equator. The prevailing winds in the middle latitudes are
Degrees of freedom (physics and chemistry) system is the sum of the average energies associated with each of the degrees of freedom: A degree of freedom is quadratic if the energy terms associated with this degree of freedom can be written as where is a linear combination of other quadratic degrees of freedom. example: if and are two degrees of freedom, and is the associated energy: For example, in Newtonian mechanics, the dynamics of a system of quadratic degrees of freedom are controlled by a set of homogeneous linear differential equations with constant coefficients. are quadratic and independent degrees of freedom if the energy associated with
