List of storms

The following 27 storms were selected because they are the top `non-insurance' storms as ranked by the storm severity index Sft = U3maxN. These storms may not have high recorded insurance losses either because they missed large urban areas, or because of incomplete loss data records. See the storm selection for more details.

Navigate to storms using the left hand buttons or click on the storm name in the table below. It's also possible to alter how these storms are sorted with the form below

* 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.
**** Sft measures strength of storm and is described in selection section.
