Air pollution over China. Layer of haze trapped over east-central China,near the coast of Bo-Hai (right). The poor air quality is due to increased vehicle pollution,coal-fired power stations,and home heating and cooking fires. Meterological influences in the area create temperature inversions; air at the surface of the Earth is cooler than air in the atmosphere. The cooler air rises,trapping the haze near the Earth's surface until the temperature changes.
