When to Find It
Can occur in any season, particularly common during stable atmospheric conditions, overcast winter days, or cool coastal mornings.

Ecological Role
Acts as a thermal blanket, trapping outgoing longwave radiation and helping to regulate surface temperatures by preventing rapid cooling or extreme daytime heating.
Easily Confused With
Altostratus clouds, which sit higher in the sky and are generally thinner, or fog, which is essentially a stratus cloud touching the ground.
Observation Tips
Best observed from high vantage points looking down or during overcast days when the cloud base is low and clearly visible above the horizon.
Interesting Facts
