Climate simulations using the IS92a and A2 and B2 SRES scenarios (Meier et al., 2004; Räisänen et al., 2004) reinforce existing
trends in storminess.
We suggest that the long - term
trends in storminess were caused by insolation changes, while oceanic forcing may have influenced millennial variability.
The uncertainty surrounding
trends in storminess was underlined, and a point was being made about this subject being controversial.
There is also low confidence for a clear
trend in storminess proxies over the last century due to inconsistencies between studies or lack of long - term data in some parts of the world (particularly in the SH).
Not exact matches
According to researchers, additional future warming of tropical Pacific waters — due
in part to human activity — should continue the long - term
storminess trend.
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).
The researchers failed to find any long - term
trends in Arctic
storminess, suggesting that summer weather hasn't been a major driver of the overall decades - long ice loss
in the Arctic.
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).
