Boundary

Cars aren't cheap as we are all aware, but none of the vehicles you've, more than likely, ever bought even scrape anywhere the boundary of the cars we are here to discuss today.

The thickness of a fog layer is largely determined by the altitude of the inversion boundary, which in coastal or oceanic locales is also the top of the marine layer, above which the air mass is warmer and drier.

The inversion boundary varies its altitude primarily in response to the weight of the air above it, which is measured in terms of atmospheric pressure.
