Figure 10: The average number of tropical storms across the globe during the August–November period as characterized by the Saffir-Simpson scale simulated by fvCAM2.2. The “present” ensemble is forced with 1990–1999 climatological sea surface conditions. The “future” ensemble is forced with sea surface conditions representative of the SRES A1B scenario at the end of the 21st century. The error bars represent the inter-realization standard error for each ensemble.
