The Extreme Weather Events That Did Not Happen
MARCH 17, 2016
Hurricanes
US land falling hurricanes have been at record low levels in recent years, and it is now more than ten years since a major hurricane hit.
Tornadoes
There has been a long term decline in both the number of tornadoes, and particularly, the frequency of stronger ones.
Droughts
Droughts were much more commonplace, prolonged and severe prior to the 1970s.
Summer Heatwaves
There has been a marked absence of extreme heatwaves in recent years, and nothing approaches the run of intensely hot summers in the 1930s.
Bitter Winters
According to NOAA’s albeit highly adjusted data, extremely cold winters are a thing of the past in the US.
Precipitation
As with drought indicators, US rainfall has tended to be greater since the pre 1970 period.
There is no indication, however, of precipitation becoming more extreme since then. The wettest year was 1973.
