A third kind of cooling fog, Upslope Fog is formed as air is forced upward along a surface and expands as it cools, due to lower pressure and temperature, and the then the water vapor condenses. Mt Washington in New Hampshire can experience Upslope more than 300 days a year.
A warming fog that forms as cold air passes over a warm water surface. It is also called sea smoke. As the warming air rises off the water, it condenses as it hits the colder air.
A Frontal Fog, another warming fog, is formed with the passage of a warm air front as warm rain falls into colder air below. The evaporating raindrops saturate the colder air layer resulting in condensation. This fog occurs frequently after a prolonged winter storm.
A very cool site of Lily the Brown Bear in MN, in torpor, having cubs on video in her den. At least one this morning! Perhaps two.
