From: Impacts of wind stilling on solar radiation variability in China

Temporal variations of annual mean direct aerosol effects (blue; Ra+u), aerosol emission effect (orange; Ra) and wind stilling amplification effect (grey; Ru) on SSR averaged over the three individual regions: (CE, SC and OT) and throughout China (CN).
Ploted values are relative to those before 1970.
