Writing in the journal Science, researchers report that rainfall is reduced by about 50% in some cases.
 
Clouds form more easily when pollutant particles are abundant, but rain droplets and snowflakes are less likely to grow large enough to fall.
 
A team of Israeli and Chinese scientists used more than 50 years worth of records to show a clear correlation between air pollution and decreased precipitation over hills in central China.
