Precip Bin Frequency

Posted: 13 Jul 2022 05:30 AM

Today's featured chart takes a look at frequency of daily rainfall events by precipitation bin and week of the year for Des Moines. The bins are arbitrarily chosen and frequencies are relative to the total events for that given week. The warm season of the year is clearly the favored time for the heaviest rainfall events as a warmer atmosphere is able to hold more water vapor and thus support heavier amounts of precipitation. It is interesting to see more heavy precip events, in a relative sense, show up in October vs April. This is likely again due to overall atmospheric temperatures being warmer during October than April.

Good = 10
Bad = 0
