Unusual global extremes in May and spring 2011
As I discussed in yesterday's post, during the spring period of March, April, and May 2011, 46% of the U.S. had abnormally (top 10%) wet or dry conditions--the greatest such area during the 102-year period of record. On average, just 21% of the country has exceptionally wet conditions or exceptionally dry conditions during spring. In addition, heavy 1-day precipitation events--the kind that cause the worst flooding--were also at an all-time high in the spring of 2011.
A highly extreme precipitation pattern was also observed over the British Isles during spring 2011. England suffered its driest spring in over a century during May, with late May soils the driest on record over large parts of eastern and central England. In contrast, Scotland had its wettest spring on record.
New Zealand had its warmest May since records began there in 1909, whereas Australia saw its coolest March-May since their records began in 1950.
