Disturbances exist on various scales in time and space, and the steady state referred to here is a flow that is on a larger scale in time and space than the disturbance of interest.

Mid-latitude disturbances are classified by horizontal scale, and the main characteristics of each are shown in the table. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
