From the text... 'Of all the meteorological elements which are known to affect forest fuel flammability and fire behaviour, rain is the most variable in its areal distribution. in its frequency, and particularly in its amount. While the measurement of rainfall is simple, evaluating that measurement in terms of the surrounding countryside is exceedingly difficult. Rainfall observed at one location s little assurance that it also rained as much, if at all, "down the road” or "over the hill”. Without an appreciation of the characteristics of rainfall, the most beneficial decisions regarding presuppression and suppression activities relating to forest fire control (Anon., 1963) cannot be made.'
