When you read about temperature inversions online, you mostly hear about them trapping pollution in places like Salt Lake City, which is surrounded by mountains. That seems to be the case for most other cities with inversion-related pollution problems, like those in California or China. Clearly the natural barrier of mountains helps trap the cap of warmer air over the cooler air by preventing it from dispersing to the side.
Is it possible for a surface temperature inversion to form in areas with a different type of topography? What conditions would need to be in place in order for a surface temperature inversion to occur outside of a valley or natural bowl?
