Order Parameter

In a nonlinear dynamic system, a variable-acting link a macrovariable, or combination of variables-that summarizes the individual variables that can affect a system. In a controlled experiment, involving thermal convection, for example, temperature can be a control parameter; in a large complex system, temperature can be an order parameter, because it summarizes the effect of the sun, air pressure, and other atmospheric variables. See: Control parameter.
