Mesoscale convective systems (MCSs) are the main cause of heavy precipitation and weather disasters over South China in spring. We objectively analyzed historic radar images and diagnosed the climatological features of springtime mature MCSs over South China. Springtime MCSs over South China occurred most frequently over central and east-coastal Guangdong and typically exhibited a linear or quasi-linear shape. The occurrences of MCSs varied considerably from year to year. We found that the MCS occurrences in April were lower during years with more aerosol pollution days This finding potentially supported our previous model study that high levels of anthropogenic aerosols suppress MCS occurrences in South China in April.
