* Storm is an addition to the original 50 storms.
+ The date given is the date that the maximum 925hPa windspeed from ERA Interim over the Continental European land mass.
** Insured losses are from Swiss Re Sigma, No 1/2004, No 2/2006, No 2/2009, No 1/2011, No 2/2012 and No 2/2013. Losses have been converted to be indexed to 2012 values. Insured loses for the storms after 2012 are from PERILS indexed to 2014 and converted to USD using 1€ = $1.12.
++ Maximum 925 hPa wind speed from ERA Interim re-analysis data over the Continental European land mass within a 3° radius of the cyclone track
*** Mean sea level pressure from ERA Interim re-analysis data.
+++ Maximum vorticity at 850 hPa from ERA Interim re-analysis data, smoothed to T42 resolution.
