Reply to Li et al: Late 20th-century drought in northern China reflects influence of global warming, aerosols, and natural variability.

Day et al. (1) present a lens for understanding the rainfall climatology of eastern China. Frontal rainfall occurs year-round due to a unique juxtaposition of continental configuration and orography. By creating an algorithm to identify frontal rain events (FREs), we are able to identify changes in properties, such as their frequency, position, and daily intensity. In our conclusion, we suggest that climate forcings, such as global warming and aerosol loading, together with … [↵][1]1To whom correspondence should be addressed. Email: jessed{at}berkeley.edu.
