I ran across an interesting article from Golf Course Industry Magazine reviewing the golfing weather from 2010. The upshot seems to be that we experienced some pretty wild effects of the periodic El Nino / La Nina cycle. But I found the most interesting bit at the end. In spite of a growing notion (at least among my acquaintances) that weather patterns have been more erratic of late, it actually seems that it’s calming down:
The Climate Extreme Index (CEI) is a value that accounts for extreme variation in weather from year to year and has been measured by the National Oceanic and Atmospheric Administration since 1996. In 2010, the index value was 9 percent above normal, a confirmation that yes, the weather during the year did produce more extremes. The good news is that CEI values have been as high as 20 percent above normal back as recently as the late 90s and have been in a decline since.
