Relatively warmest month on record
Posted:
                    Our recently finished month of March has rewritten the record books in 
the Upper Midwest and in some respects, was relatively warmer than the 
iconic months during the dust bowl era! The featured chart presents the 
monthly record temperatures for Des Moines.  The top chart presents the 
record temperature along with the year it occurred and the sigma 
departure the value was from current day average.  The bottom chart 
presents the amount the current record is warmer than the second 
warmest month on record.  The value of 3.5 sigma is shown for March 
2012, which is larger than any of the other months.  The sigma value 
represents how far the observation is away from the mean distribution 
of climatology.  It provides a simple, but not complete, means to 
compare different months of the year. Regardless of that comparison, 
the bottom chart shows another exceptional aspect by besting the 
previous record by over four degrees!  In this regard, this month is 
the most exceptionally warmest as well!  Amazing to think about what we 
just experienced in the context of climatology for Iowa!
