U SECRET The yearly sums of (+) values and (-) values describe the yearly precipitation regime at a location, as illustrated for Missoula in Table 4. The sum of (+) values does not include any month when mean temperature is less than 400 F-the approximate lower limit for plant growth activity. At lower temperatures the level of soil moisture content is not considered as a major factor limiting plant growth. Also, in calculating the yearly sum of(+) values the maximum value used for any month is +40. This value represents a rather humid month-equal to an average monthly precipitation of 4.51 inches occurring on 10 rain days for a month having an average daily mean temperature of 600 F. The highest possible humidity value for a location is 12 times 40, or +480. The (-) values for all bum months-designated as "B" months-are totaled, regardless of monthly mean temperature, in calculating their yearly sum. N Table 4 Missoula, Montana Month Av. Av.
