The drought index chart as a fire weather forecast tool / by A.W. Jackson = Utilisation de la carte de l'indice de sécheresse pour la prévision du temps à incendie / par A.W. Jackson.: En57-57/682-1968E-PDF
"The determination of the drought index (in the U.S., the build-up index) for many weather stations is a routine part of fire weather analysis. Maintaining these values from day to day for a number of stations enables one to draw lines of equal drought index in order to gain a continuing picture of drought conditions. "Normal" drought index charts may be prepared and graphical subtraction of values on this chart from those on the current one gives a picture of the above-normal and below-normal drought areas. Graphical addition of conditions of humitity and wind to the drought picture may be done to obtain a chart of fire weather index from which fire danger may be deduced. The same procedure may be used to obtain a forecast chart of the index"--Abstract.
