«One societally relevant implication is that more
storminess probably means more erosion of Arctic coastlines, especially in tandem
with declines in buffering sea ice cover and increases in thawing coastal permafrost,» concluded Dr. Vavrus.
These changes have been compounded by stronger waves in the North Sea in recent decades, and could be further exacerbated if predictions that
storminess will increase
with global warming prove accurate.
Alarmists have drawn some support for increased claims of tropical
storminess from a casual claim by Sir John Houghton of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) that a warmer world would have more evaporation,
with latent heat providing more energy for disturbances.
Off the top of my head I can think of at least three teleconnections connected
with El Nino: increased precipitation in the SW US, decreased Atlantic hurricane activity and increased
storminess along the SW coast of Africa and around the Cape of Good Hope.
However,
with recent developments in modelling approaches and computational resources examining the potential impacts of changes in
storminess has become feasible, as exemplified by studies of Muis et al (2016), who used the first dynamic global storm surge model to simulate past water levels for the global coast, or Vousdoukas et al (2016), who simulated future storm surge changes along the entire European coast.
Although the age model gives some uncertainty in the timings, it appears that
storminess increased at the onset and close of North Atlantic cold events associated
with oceanic changes,
with reduced storm activity at their peak.
An impact that is, ironically, driven both by Antarctic continental ice melt together
with an increasing
storminess in the Southern Ocean and waters more heavily laden
with salt issuing from the equatorial zone.
The results suggest
storminess increased after 1000 cal yrs BP,
with higher
storminess during the Medieval Climate Anomaly (MCA) than the LIA, supporting the hypothesis that the NAO -
storminess relationship was consistent
with the instrumental period.
These experiments also show a decline in
storminess and wind intensity eastwards into the Mediterranean (Busuioc, 2001; Tomozeiu et al., 2007), but
with localised increased
storminess in parts of the Adriatic, Aegean and Black Seas (Guedes Soares et al., 2002).
They further note that these changes in coastal hydrodynamics were in phase
with those observed over the Eastern North Atlantic... and that the periods of increased
storminess they identified seem to correspond to periods of Holocene cooling detected in the North Atlantic...» [Pierre Sabatier, Laurent Dezileau, Christophe Colin, Louis Briqueu, Frédéric Bouchette, Philippe Martinez, Giuseppe Siani, Olivier Raynal, Ulrich Von Grafenstein 2012: Quaternary Research]
Climate variability associated
with the North Atlantic Oscillation (NAO) determines many physical coastal processes in Europe (Hurrell et al., 2003, 2004), including variations in the seasonality of coastal climates, winter wind speeds and patterns of
storminess and coastal flooding in north - west Europe (Lozano et al., 2004; Stone and Orford, 2004; Yan et al., 2004).
«The authors write that «the Mediterranean region is one of the world's most vulnerable areas
with respect to global warming,»... they thus consider it to be extremely important to determine what impact further temperature increases might have on the
storminess of the region... produced a high - resolution record of paleostorm events along the French Mediterranean coast over the past 7000 years... from the sediment bed of Pierre Blanche Lagoon [near Montpellier, France]... nine French scientists, as they describe it, «recorded seven periods of increased storm activity at 6300 - 6100, 5650 - 5400, 4400 - 4050, 3650 - 3200, 2800 - 2600, 1950 - 1400, and 400 - 50 cal yr BP,» the latter of which intervals they associate
with the Little Ice Age.
The NAO's prominent upward trend from the 1950s to the 1990s caused large regional changes in air temperature, precipitation, wind and
storminess,
with accompanying impacts on marine and terrestrial ecosystems, and contributed to the accelerated rise in global mean surface temperature (e.g., Hurrell 1996; Ottersen et al. 2001; Thompson et al. 2000; Visbeck et al. 2003; Stenseth et al. 2003).
Claims for starkly higher temperatures are based upon there being more humidity, not less — hardly a case for more
storminess with global warming.
With regard to
storminess and precipitation, the TAR states that there is no trend towards extremes.
They found no long - term trend during the last 100 years, but a clear rise since a minimum of
storminess in the 1960s, which is consistent
with the rise in extreme geostrophic wind found by Jones et al. (1999c).
