Reality Check (R-Check) Method for Seasonal Forecast
This section helps the memebrs of the expert comittee to review the
forecast based on other forecasts available.
Step 1: Internal Check against previous
forecasts
When a forecast has preceding forecasts, it is important to review if
there seems to be continuity with the previously issued forecast for the
season.
Guiding questions
- What was the previous forecast?
- If this isn’t the first forecast issued for the relevant period,
does the forecast look radically different from the previous forecast
issued?
Step 3: Checking the generated forecast against
other published forecasts
Compare the result with friends and others, this means comparing the
result with rainfall forecasts on similar seasonal or regional length
made by other organizations. This includes Meteorological Services, as
well as relevant regional and international centers working on the
target area.
Guiding question
Looking at the relevant forecasts, are these other forecasts looking
similar? (Ie, looking at the NMME, ICPAC, Copernicus)
