In the winter, large landmasses often develop a seasonal temperature inversion, where warm air traps cooler air near the surface. This phenomenon can lead to increased air pollution and fog, as pollutants become trapped in the cooler air layer. Additionally, it can cause notable differences in temperature between the ground and the air above, affecting local weather patterns and ecosystems. Such inversions are common in valleys and areas with significant snowfall.
