✦ Synopsis

A method is described for specifying climatic variability using a principal component analysis of real and derived meteorological variables. Two vectors derived from the analysis delimited areas in Western Australia between which climatic differences were large relative to those within such areas. These vectors were used to construct a grid map of the region. This map was then used in studies on the ecology of wild oats in Western Australia which required the location of a number of complex experiments at sites chosen to sample regional climatic variation.

A note of caution is given emphasising that variables should not be selected carelessly and stressing the undesirability of necessarily attempting to explain individual vectors.
