Short summary
This study examines how snow cover over the Tibetan Plateau and oceanic conditions influence air quality in China during winter. By analyzing weather data and pollution levels, we found that variations in snow cover affect weather patterns linked to fine particulate matter pollution. Our results emphasize the need to consider both snow and ocean influences in air quality predictions, aiming to improve forecasting models and support better public health and environmental management strategies.
