The number of occurrences during the 1955-2007 period of total precipitation that is below the median (i.e., the 50 %ile), below the 40 %ile, below
the 30 %ile, below the 20 %ile and below the 10 %ile for a given number of consecutive running 3-month periods. Three consecutive periods would
be, for example, Feb-Mar-Apr to Apr-May-Jun of a given year. Results are shown for each number of consecutive periods on an individual basis: i.e.,
results for 4 consecutive running periods do not include results for 3 periods, even though all instances of 4 periods by definition include two cases of
3 periods, three cases of 2 periods, etc. Similarly, results for a severely dry percentile (such as 10%ile) do not include the results for the milder percentiles
(such as 20%ile, 30%ile, etc.). Users wishing to form cumulative tables may form upward-running totals in each percentile column, or rightward-running
totals in each frequency row. The reasoning behind choosing individual rather than cumulative occurrences, and the meaning of the results presented
here, are described in the text.
