Assessing the Atlantic Hurricane Season Climate Factors
Historical conditions are available for comparison to the current situation. Time series are useful for comparing trends over time. The individual maps are useful as a snapshot of the conditions for a given time period.
Hurricane Related Time Series
The time series below compare the number of hurricanes per year with the corresponding sea surface temperature (SST) and wind shear conditions over the Main Development Region (MDR). Click on an image to see a larger view.
You can obtain historic maps from 2005. The SST maps are based on the monthly NOAA OI SST. The climatology used is 1971-2000. The wind shear plots are based on the NCEP/NAR Reanaysis
