Large-scale weather conditions known as stagnations (slow-moving high-pressure systems) are characterised by a combination of low wind speed and very limjited vertical mixing. Furthermore, they can last for days, leading to very serious buildups of pollutant concentrations.

The general concern about industrial stagnation inspired an overhaul of the patent system.
