  1. SUMMARY:The proposed relationship between sea surface temperature (SST) and tropical cyclone activity is tested with data for global mean Accumulated Cyclone Energy (ACE) in all six basins and global mean SST in the study period 1945-2013.  Three different time scales from annual to decadal are studied. Although some strong correlations are seen in the source time series, no correlation is found in the detrended data. A test with only Northern Hemisphere tropical cyclone basins and Northern Hemisphere SST also failed to find the needed correlation. We conclude that no evidence is found in these data to relate the ACE measure of tropical cyclone activity to mean SST. 
  2. BACKGROUND: Sea…
