Fog Could Be A Problem For Upcoming Mornings


A mixture of radiation and advection fog could affect the next several mornings. With the additive ingredient of light winds, sea fog will form over night.

North Florida and South Georgia average around 45 days of significant fog a year. November is characteristically the month with the most fog. This is because of the stark temperature contrasts as one goes up in height. Moisture in the top bed of the soil is another main ingredient for the production of fog.    


October and November Are The Foggiest Months

Fog Definitions:
>Advection fog is created when moist air passes over a cool surface, and the air is cooled. As the air is cooled it reaches its relative humidity saturation point and fog is formed.

>Radiation fog is relatively shallow fog. Radiation fog is also known as ground fog. It is produced near the ground. It is formed by the cooling of land after sunset by thermal (infrared) radiation in calm conditions with a clear sky.
