Develop knowledge of regional and local climatology to define the type(s) and magnitude of precipitation expected during different seasons.
Forecasters need to understand the seasonal and diurnal variation of the magnitude and types of precipitation expected in their area of forecast responsibility. A complete set of geophysical and climatological information should be available to describe the local and regional effects upon the frequency, magnitude, and seasonal variation of precipitation.
1.� Understand
the seasonal variability of precipitation over the region of interest and its
relationship to orography and synoptic flow regime
2.� Understand
the synoptic, mesoscale, and local forcing associated with extreme
precipitation events over the region of interest.
3.� Use
climatological knowledge to assist real time precipitation forecasting.
4.� Create
and/or employ an easily accessible database of climatological data for
forecaster reference.
Instructional Component 1.1: Precipitation Climatology Database.� Develop and/or access a climatological precipitation database that illustrates the precipitation variability and extremes in the region of interest.� This should include information about the probability of precipitation amount and type as a function of the time of day, month and season.
Instructional Component 1.2: Case Studies.� Local case studies of extreme events, which include a detailed description of the synoptic, mesoscale, and local effects upon the storm. Instructional Component 1.3: Station-led Training.� Geographically similar groups of field offices and others should work together to share information and highlight potential/local issues.Return to Quantitative Precipitation Forecasting PDS page
