Based on the future projection of high-resolution regional climate simulations under the medium-low radiative forcing scenario, the haze pollution potential tends to increase almost over the whole of China except central China, and this increase would be generally aggravated over time. There would be a higher probability of pollution risk over Beijing–Tianjin–Hebei and Yangtze River Delta in winter, over Pearl River Delta in spring and summer, and over Northeast China throughout the whole year.
