山崩连续体模式之数值仿真(英文)

Recent advances in landslide/avalanche modeling have been enabling us to investigate the kinematics of such catastrophic events with much more details.Taiwan is located in a region where seismic activities and extreme weather conditions frequently occur.One of their common consequences is the slope failure.In the past decodes,we witnessed at least three giant landslides:Tsaoling,Jiufenershan landslides,triggered by the Chi-Chi earthquake

2003-2013年高雄市霾日数变化规律与影响因素研究

利用2003-2013年高雄站的气象观测数据,统计分析了高雄地区日平均能见度低于5km、平均相对湿度低于80%的霾天气的长期变化。研究发现:近年来高雄市的霾日数在逐年减少;霾日在1年内各季节均有发生,霾日数在冬、秋、春、夏季依次减少。全年霾日一月份发生最多,七月最少,1d内11:00发生霾的可能性最大。在相对湿度小于80%时,随着相对湿度的增大,霾发生的可能性增大;气温越低,越易出现霾日;当风速小于3m·s-1时,霾发生的可能性最大,并且其主导风向为NNW。霾与空气污染指数在年际变化和月变化上都有一定的相关性;PM2.5和PM10的浓度越大时,对霾的形成越有利。
