Dense Fog Advisory Counts
Posted: 20 Jan 2017 05:40 AM
A Dense Fog Advisory is in effect for the entire state this Friday morning. The featured
chart presents some frequency metrics for how often this weather alert is issued for
somewhere in the state of Iowa. The top panel shows the weekly frequency of having at
least one event for that week per year. The bottom panel shows the overall total number of
events. The winter months are certainly the most common time of year for this product with
summer having the least. Fog is easier to maintain during the winter thanks to moist air
masses over top a colder ground surface which helps to keep air temperatures near water
vapor saturation.
