Resumen:
A 5-class intensity scale for wave storms in the Catalan coast is
presented. This has been done by analysing a storm data set which
comprises 5 buoys during the period 1988/2008. The obtained
classification improves the former proposal of Mendoza and Jimenez
(2008) by better resolving spatial and temporal variability in wave
storms in the area. The obtained classification reflects the increase in
wave storm properties as the storm category increases. Because the
selected classification parameter was the energy content which
implicitly contains H-s and storm duration, this variable was used to
define class limits; class I storms (24-250m(2) h), class II storms
(251-500m(2) h), class III (501-700m(2) h), class IV storms
(701-1200m(2) h) and class V storms (> 1200m(2) h). The energy content
variable was also used as proxy for induced hazards; the observed
increase in energy content for higher classes reflected a significant
increase in the intensity of the potential hazards. Lastly, the dominant
synoptic situation for wave storms along the Catalan coast was the
presence of a Mediterranean cyclone although a direct correspondence on
cyclone's intensity over the western Mediterranean with wave energy
content was not found.
