CMIP5 Cyclone Intensities

All plots show:

Maximum intensity distributions based on T42 filtered 850-hPa relative vorticity (ξ850), and full-resolution mean sea level pressure (MSLP) and 850-hPa winds, for all seasons and both hemispheres. MSLP and 850-hPa winds referenced to ξ850 tracks. Values are number per month for the period 1986-2005 for the Historical experiments and ERA-Interim reanalysis and for 2081-2100 for RCP4.5 and RCP8.5 experiments. Bin widths are 10 hPa for MSLP, 5 ms-1 for winds, and 1×10-5 s-1 for vorticity; SH vorticity is scaled by -1.

For a full description of the method* used to reference the maximum intensity distributions to the cyclones see: Hodges, K. I., R. W. Lee, L. Bengtsson, 2011: A Comparison of Extratropical Cyclones in Recent Reanalyses ERA-Interim, NASA MERRA, NCEP CFSR, and JRA-25. J. Climate, 24, 4888-4906. doi: http://dx.doi.org/10.1175/2011JCLI4097.1.

(* note: differences from this method are: here T42 relative vorticity distributions are shown rather than full resolution vorticity, so as the results are not biased by differing model resolution; and, full resolution winds are at 850-hPa here rather than 925-hPa as in Hodges et al. 2011.)

Data can be made available in other formats upon request.
