AccuWeather's Melissa Constanzer goes over three different types of fog while also explaining why fog is so common during the fall season, especially during the morning.

Fog is a common feature during the fall season, often leading to foggy mornings. The main reasons for this are two types of fog that are prevalent in autumn: radiation fog and evaporation fog. Radiation fog forms when the ground loses heat overnight, cooling the moist air near the surface and causing condensation. Evaporation fog, on the other hand, typically occurs near bodies of water that remain warmer than the surrounding air, leading to visible steam or vapor-like fog as the air above the water cools.

A third type of fog, known as advection fog, is more common in spring and involves warm, moist air moving over a cold surface. For those traveling in foggy conditions, it is advised to use headlights and exercise caution.

Why fog is so common during the fall season

It is the season for fog. Yeah, when we talk about fall, we often can find foggy mornings to start the days. So what do we mean by all this? Well, there are three types of fog. What makes fall so foggy? Two of the types of fog. First up, we have infection type fog, which is actually most commonly occurring in spring. It's when you have cold ground, potentially even snow covered ground, and you have a warm, more moist air mass that moves over top of it. Gets cooled enough to create fog at the surface. The other two that we have radiation on radiation fog that occurs very commonly in fall and even evaporation fog. Let's first talk about radiational fog because this one is due to the loss of heat during the overnight hours. So once we set that sun to bed, all of a sudden the ground starts to cool and there's usually a moist layer of air that gets trapped near the surface underneath a drier layer of air. And as that moist layer of air produces more moisture and cools then because it's lost its heat source, the ground that is now cooling as well. We can develop a lot of fog right there, chilling that moisture enough to create the fog that we see. The other type of fog that we can get this time of year usually occurs near bodies of water that are still relatively warm. It could be rivers, or it could be also lakes and different types of streams. You have that warm water temperature compared to the air, and of course, that's going to put moisture into the air above it. It also is going to help to warm some of that air just above the surface so it can hold more moisture. In the air and as that continues to then cool, you can see this steam or vapor like fog that occurs as you get near bodies of water. Do remember that if you are trying to travel through fog, make sure to turn on your headlights and be safe. Don't just pull on the side of the road.
