When viewing a distant fire on a clear day, have you ever noticed that the smoke looks like it hits a lid? This is a great way to see a temperature inversion in the atmosphere. Simply put, this is where air warms with height instead of cooling. This prevents the cooled smoke from being able to rise further, so it begins to spread horizontally.
