October Temperature and Precipitation Percentile Maps


One way to depict how a month or season compares to its history is to use a ranking system. NCEI has done this for many years for the climate divisions, states, etc. The maps below depict rankings based on the 5km gridded dataset, nClimGrid. Each grid point is ranked based on the other values in its own period of record.

Ranking the grid cells provides a greater detail for the regional patterns across the U.S. For instance, much of the southern U.S. experienced much below average rainfall in October. This dryness is also evident in the climate division rank maps. However, the newly developed gridded percentile maps reveal finer details, like the record dryness in southwestern Alabama stretching southward into the Florida Panhandle.
