Abstract. Cold frontal passages usually promote quick removal of atmospheric pollutants over North China (e.g. the Beijing–Tianjin–Hebei region). However, in Yangtze River Delta (YRD), cold fronts may bring air from polluted Plain (NCP), thereby deteriorating quality YRD. In this study, a passage and subsequent stable weather event YRD during 21–26 January 2015 was investigated with situ observations Weather Research Forecasting – Community Multiscale Air Quality Modeling System simulations....
Abstract. Urban heat island (UHI) and urban air pollution are two major environmental problems faced by many metropolises. The UHI affects changing the local circulation chemical reaction environment, e.g. temperature relative humidity. In this study, WRF-CMAQ (Weather Research Forecasting Community Multiscale Air Quality) model was used to investigate impact of an on vertical distribution aerosol particles, especially secondary inorganic (SIA), taking strong in Hangzhou, China, as example....
Impacts of coastal local circulations and their interactions on ozone (O3) in Hangzhou 5 June 2018 with relatively low temperatures were investigated using surface observations three-dimensional air quality simulations. Local primary causes the episode instead high temperatures. Northwesterly land breeze previous day transported O3 to sea, sea (SB) blew pollution back land. Inland penetration (east west) combined SB front (SBF) was accelerated by urban heat island (UHI) induced easterly flow...
For urban weather finescale forecasting, obtaining accurate and up-to-date canopy parameters (UCPs) is necessary still a challenge. In this study, high-resolution dataset of UCPs was developed by using vector-format building information then applied in the WRF/urban system with single-layer model (SLUCM)/building effect parameterization (BEP) to improve forecasting typical heat wave event during summer 2016 Hangzhou. A series sensitivity experiments were conducted, results showed that UCP...
Abstract The impacts of topography and urbanization on an extreme rainfall (ER) event in the Hangzhou Bay (HZB) region were investigated using Weather Research Forecasting model with one control simulation three artificial scenarios no‐HZB, no‐mountains south bank HZB, no‐urban. Thirty members different combinations physical parameterizations considered for each scenario. test results evaluated they showed that well reproduced ER occurred HZB region, ensemble valuable credible. existence...
Abstract Valley winds and urban breezes induced by thermal circulation have been the subject of numerous studies; however, their interactions deserve further observational study under different geographical conditions globally. We propose quantitative criteria for analysis observations, including identification valley mountain–plain wind episodes, determination direction duration winds, exclusion suspect cases strong synoptic systems. selected a subset 345 days that occurred during 2013–2015...
Abstract. Cold frontal passages usually promote quick removal of atmospheric pollutants over North China (e.g. the Beijing–Tianjin–Hebei region). However, in Yangtze River Delta (YRD), cold fronts pose a potential threat to air quality. In this study, passage and subsequent stable weather event YRD during 21–26 January 2015 was investigated with in-situ observations Weather Research Forecasting–Community Multiscale Air Quality Modeling System simulations. Observations showed burst PM2.5...
