When should you expect advection fog to rise into low hanging stratus clouds?

Advection fog is typically associated with warm, moist air moving over a cooler surface, which causes the air to cool and condense, forming fog. For advection fog to rise into low-hanging stratus clouds, specific atmospheric conditions must exist.

When considering wind speed, greater than 15 knots can enhance mixing in the atmosphere. This mixing can create conditions that allow the fog to dissipate or rise into the lower layers of the atmosphere, such as stratus clouds. Specifically, when there is enough wind to stir the air, it can carry the moisture higher, allowing fog to transition into stratus cloud formation, especially if the wind is strong enough to overcome the stability of the air near the surface.

The other options describe conditions that impact fog formation and dissipation but do not directly relate to the rising of advection fog into stratus clouds as effectively as wind speed does. For instance, surface heating typically occurs after sunrise, but that is not the main factor for advection fog rising—it's more related to thermals and local heating rather than simply lifting fog. Similarly, while temperature inversions and high humidity levels are crucial for fog formation, they do not provide the necessary dynamics to cause the fog to ascend into the cloud layer as wind
