developed in the northwestern Pacific on 16 September 2013, and it dissipated on 24 September 2013. Its maximum intensity reached 140 knots (kt; 1 kt = 0.51 m s −1 ) and it made landfall in the Pearl River Delta of China, which is a region where a considerable amount of anthropogenic pollution is emitted. Therefore, it is instructive to investigate the effects of anthropogenic aerosols on typhoons, particularly as they approach the Pearl River Delta. 2. Model description, configuration, and experimental

, with values up to 50 μ g m −3 in southern Iowa and Nebraska and up to 30 μ g m −3 along the Missouri River valley ( Fig. 2a ). Much of the PM 2.5 in the northern portion of the domain is composed of sulfate ( Fig. 2b ) and is driven by the interaction of the relatively large amount of ammonia emitted from the agricultural region in the northwest of the domain and incoming sulfate from the northeastern boundary. Evaluations of AirNow hourly station data PM 2.5 in this region of the domain show

for Ns clouds are also found north of 30°N, characterized by a migration of cloudy belt from 32°–37°N in May to 35°–40°N in August. This march of the monsoon usually leads to a rain belt propagating from southern China to the Yangtze River basin in June and finally to northern China in July and August. In September, the maximum in the OF H for DCC weakens and moves back to the south because the rain belt moves southward (between 26° and 29°N) when the monsoon period ends. Additionally, large OF H

_AME run, and (c) Mode_MRE run. The shallow cumuli on 25 May, a deep convective cloud on 26 May, and a stratus on 27 May are detected and simulated. The LWP measured by the microwave radiometer (MWR) with a uncertainty of 20–30 g m −2 over various atmospheric conditions ( Turner et al. 2007 ) and the precipitation rate estimated by Arkansas–Red Basin River Forecast Center (ABRFC) are also used for model evaluation. The simulations reproduce the temporal variations of the LWP and precipitation rate
