Winter Low Ceilings

Posted: 03 Jan 2017 06:01 AM

Monday was a rather dreary day with low clouds, freezing rain, and then rain. Winter is the season for such low clouds as shown by the featured chart. The chart depicts a histogram of cloud ceilings as estimated by the Ames Airport weather station. The darker reds represent the more conditions. There is a clear signal in the lowest levels during the coldest half of the year. Low clouds are more difficult to persist during the warmer season as solar inputs generally are able to warm the ground to mix the lower atmosphere.

Good = 11
Bad = 0
