Extremes in June

Posted: 24 Jun 2011 07:05 AM

This June has seen its fair share of extreme high temperature both on the warm and cold side. The featured chart compares the number of days above the 75th percentile with the number below the 25th for each June back to 1893. An average year would see around 15 days per month within these two intervals. Interestingly, it is much more rare to see many days in a month below the 25th. This is because the cold patterns tend to be more transient than the hot and dry patterns that can be reinforced by ample sunshine and dry conditions.

Voting:
Good = 13
Bad = 12
