Precip Reliabillity

Posted: 12 Aug 2014 05:27 AM

After yet another recent wet spring, the later part of summer has turned dry again. The featured chart looks at the recent 20 years of monthly precipitation reliability. The metric plotted is the number of years that the given month had above 100% of average precipitation for the month. These values are for Ames. Rewording, 70% of the past 20 years had above average precipitation for April. So while April is shown with the highest value, September has the lowest at just 30%. This chart can be dynamically generated on the website, so please try different thresholds and periods to see what results you get!

Good = 16
Bad = 6
Abstain = 9
