Daily Precipitation

Posted: 11 Jun 2014 05:55 AM

The featured chart presents the daily climatology of precipitation for Ames using period of record data. The blue line represents the simple daily average of precipitation using all days and the red line is the simple average over only the days on which precipitation was reported. These two lines answer the question what is the average daily precipitation and what is the average daily precipitation when it actually precipitates that day. While the blue line peaks in early June, the red line plateaus through the summer. The nature of the summer time thunderstorms is rather consistent over the summer months, but their frequency decreases as the summer passes. So the blue line peaks during the peak in thunderstorm activity, while the red line decreases once we are out of summer and into September.

Good = 11
Bad = 4
