Regional climate changes have adverse socioeconomic impacts, especially in a megacity. As case study, we investigate the regional of Chengdu, most densely populated cities western China. In past 40 years, Chengdu underwent warming and less humid trends over entire region. Consistently, number annual fog days decreased by −20.5 days/10 years on average, frequency hot extremes increased. The contributions to from global urbanization are investigated, separately. Based 21 simulations CMIP6...
Abstract Humid heat extremes, taking account of both temperature and humidity, have adverse impacts on society, particularly human health. It has been suggested that quasi-stationary waves (QSWs) with anomalously high amplitudes contribute to the occurrence near-surface precipitation extremes in midlatitudes Northern Hemisphere. However, little attention paid linkages between amplified QSWs humid extremes. Using ERA5 dataset, we identify zonal wavenumbers 5–7 (Wave 5–7) summer months from...
Summer weather extremes (e.g., heavy rainfall, heat waves) in China have been linked to anomalies of summer monsoon circulations. The East Asian subtropical westerly jet (EASWJ), an important component the circulations, was investigated elucidate dynamical linkages between its intraseasonal variations and local extremes. Based on EOF analysis, dominant mode EASWJ early is characterized by anomalous westerlies centered over North easterlies south Japan. This conducive occurrence precipitation...
