Climatological Percentiles

Description

Conceptual Climatological Percentile graphic of MSLP.

Climatological percentile products are used to assess whether forecast variables have unusual values compared to a model climate or reanalysis climatology. Forecasters are not always familiar with what constitutes a typical range of conditions. Therefore, a comparison to model or observed climatological data is useful to help identify anomalous forecast conditions that could cause significant weather impacts.
