Point Process Models of Rainfall

摘要

Point process models of summer rainfall for the Potomac River basin are developed for application to streamflow prediction during drought periods. The point process models that are developed include (1) a univariate point process model of rainfall occurrences at a site, (2) a marked point process model of rainfall occurrences and storm depths at a site, and (3) a bivariate point process model of rainfall occurrences at two sites. This interpretation is supported by presenting evidence which indicates that periods of deficit summer rainfall in the Potomac basin are closely associated with the advection of cool, dry, stable Canadian air masses.
