年初就有气象学家发出警告,因为气候异常,今年有可能出现“九八”那样的洪涝灾害。入夏以来,气象学家的预言应验了。南方多座城市饱受洪涝灾害困扰,给民众生活带来诸多不便,一时间,网上各种“看海”的调侃不绝于耳,更有人又一次把矛头指向城市规划。其实,洪涝灾害是一种常见气象灾害,之所以近年来频发,最主要的原因还是厄尔尼诺现象造成的大气环流变化,有的地方暴雨成灾,有的地方干旱少雨。脱离开这个大环境变化,谈论城市气象灾害,难免有管窥之嫌。
At the beginning of this year, meteorologists warned that as a result of the unusual weather, this year there may be floods such as the 1998 earthquake. Since the beginning of summer, the meteorologist’s prediction has been fulfilled. Many cities in southern China have been plagued by floods and disasters, bringing inconvenience to people’s lives. For a time, all kinds of online “watching the sea” ridicule. Some people once again point the finger at urban planning. In fact, flood disasters are a common meteorological disaster. The reason why frequent occurrences have occurred frequently in recent years is that the atmospheric circulation changes caused by the El Nino phenomenon have changed. In some places, torrential rains have made disaster and in some places, it has been drier and drier. Apart from this major environmental change, talking about urban meteorological disasters, it is inevitable there is suspicion.
