June Sigma Departures

Posted: 03 Jul 2017 05:26 AM

With the calendar now saying July, it is a good time to look back on June in Iowa. The featured chart compares June growing degree day and precipitation departures for a statewide Iowa average value. These departures are expressed in terms of standard deviations (sigma) from the mean. This allows for a comparison between variables that have different units of measure, but have similar statistical distributions. The value for 2017 came in just above average for GDDs and below average for precipitation. Years that are on the fringes of the plot are labelled as well.

Good = 6
Bad = 0
Abstain = 1
