The study looked at how heavy and light rainfall patterns have changed in different parts of China from 1961 to 2006. They found that in most regions, heavy rainfall has increased while light rainfall has decreased as temperatures have risen. This shift is more pronounced in warm and humid areas compared to colder regions. The changes are more noticeable in winter than in summer, showing that winter precipitation is more affected by rising temperatures. Overall, the findings suggest that heavy rainfall events are becoming more common in China due to global warming.
