Daily Consecutive Dry Day Probability

 

Product Overview

 

Conditional probabilities of observing consecutive dry day episodes of length 1 30 days preceding daily precipitation events of variable magnitudes (0.01, 0.10, 0.25, 0.50) were computed for 7 regions across New York.  These regions are the same subregions of stations used to compute weekly extreme precipitation probabilities, since both deal with the timing of events throughout the annual cycle.  Given the occurrence of a precipitation event (with user-specified magnitude), the values on each graph provide the probability that such an event was preceded by a dry-day sequence of greater than or equal to n days (n=1-30).
