Temperature Climatological Perentiles

Observed temperature percentiles.

This map shows the 1982-2010 historically observed seasonal percentile value. By default showing the averaged seasonal temperature value for the 50th percentile of the December-February season. Users can express the percentile in anomalies relative to the 1982-2010 climatology; choose one of the 17 percentiles that the Flexible Forecast allows to look at, as well as the traditional tercile values; and eventually pick another of the 12 3-month long seasons of the year.

Clicking on the map will generate some information about the location clicked, and a graph plotting all the 19 percentile values for that location, either as averaged temperature or anomalies and for the chosen season.
