Abstract:
Analyse the serious drought disaster of Chongqing in 2006 from large-scale in national and small-scale in local, based on this, analyse the causes about Climate backdrop circulation features, topography and human factors, the following conclusion are following: this high temperature and drought disasters in Chongqing is a extreme weather event on a global warming and drought-prone period of backdrop. Atmospheric circulation anomalies is the main reason for the current drought, the western Pacific subtropical high was more northerly, western, and stronger; the Tibetan high was more northerly and stronger, the blocking high in east Asia was not obvious, cold air was not activity. the accelerate role of typhoon conditions and lack of vapor. These climatic factors interact organic between dynamical and material prerequisites (moisture) beget the high temperature and drought. In addition, the topography and human factors also facilitated high temperature and drought, exacerbated the magnitude of the disaster.
