Very Active Tornado Season Another Classic La Nina Effect
By Joseph D’Aleo, CCM
The winter and spring brought heavy, in places all-time record snowfall, flooding, and now an active tornado season. All of these are classic strong La Nina phenomena. Brush fires now ablaze in Florida are is also a common springtime La Nina hazard.
The most fatalities from tornadoes occurred in the 1920s (peak 1928) (source NSSL). In recent decades, deaths were less with the exception of the two years with SUPER OUTBREAKS, 1965 and 1974 (both years coming off La Nina winters, in 1974, one of the strongest)
See this entire story with more on those superoutbreaks here.
Don’t let anyone tell you this is the result of global warming. This May has with the exceptions of a few pockets, been a cold month so far thanks to high latitude blocking and a suppressed jet stream. With that forecast to continue, expect more widespread unseasonably cool temperatures and severe weather ahead.

ICECAP, International Climate and Environmental Change Assessment Project, is the portal to all things climate for elected officials and staffers, journalists, scientists, educators and the public. It provides access to a new and growing global society of respected scientists and journalists that are not deniers that our climate is dynamic (the only constant in nature is change) and that man plays a role in climate change through urbanization, land use changes and the introduction of greenhouse gases and aerosols, but who also believe that natural cycles such as those in the sun and oceans are also important contributors to the global changes in our climate and weather. We worry the sole focus on greenhouse gases and the unwise reliance on imperfect climate models while ignoring real data may leave civilization unprepared for a sudden climate shift that history tells us will occur again, very possibly soon.
