Changes of the seasonal predictability of historical sea surface temperature related to Atlantic hurricanes

This directory contains the predicted summer mean (ASO, i.e., August, September and October) SSTA indices related to the Atlantic Hurricanes from CESM ensemble hindcasts during period 1900-2017 that are used for a manuscript ("Changes of the seasonal predictability of historical sea surface temperature related to Atlantic hurricanes") submitted for Geophysical Research Letters. Description: The predicted index of summer mean SSTA in the MDR is calculated as the area-averaged SSTA in the MDR region (80°W-20°W, 10°N-25°N). The predicted index of summer mean SSTA in the tropical belt is calculated as the area-averaged SSTA in the tropical belt (180°E-180°W, 30°S-30°N). The predicted index of summer mean SSTA in the sub polar North Atlantic is calculated as the area-averaged SSTA in domain of 60°W-0°, 50°N-65°N. The predicted index of summer mean Nino3.4 index is calculated as the area-averaged SSTA in domain of 170°W-120°W, 5°S-5°N. The predicted index of summer mean Sglobal mean SSTA index is calculated as the area-averaged SSTA over the global domain. All indices are derived from the CESM ensemble hindcasts that are initialized from the 1st of July during each year spanning from 1900 to 2017. All indices are anomalies with the climatology during period 1900-2017 being removed
