What causes clouds to form? In some cases, mountains are the answer!
When wind blows up over a mountain range, the air rises and cools, and eventually enough moisture will condense out of the air to form a cloud. This results in lenticular clouds (picture 1) and stratus clouds (picture 2)!

Extreme weather can delay travel and pose serious safety risks, but our research supports safe travel in the sky and on the road. We’re providing pilots with tools to steer clear of storms and developing systems to keep vehicles safe in winter weather. https://researchworks.ucar.edu/travel/

NSF NCAR scientists are working on an experimental hurricane forecast using advanced computing w/ Model for Prediction Across Scales (MPAS) run on the Derecho supercomputer. So far, this new system predicted Typhoon Ragasa, the strongest weather system this year, many days ahead in high definition.

So, when you see an ozone alert, it's about air quality conditions near the ground where we live and breathe, and not about the protective ozone layer high above us!
