Table 1 Frequency of when the observed number of TCs in 2005 is exceeded.

The percentage of years the modeled GPIs exceed the observed 2005 number of 28.0 and the calculated 2005 reanalysis GPIs over the entire North Atlantic basin. Values in parentheses include an internal variability of two TCs in the model-calculated GPIs. The number of years of simulation is included for each model.
