Dynamic research and analysis of the 2010 La Nia
2010年拉尼娜事件发生的动力机制研究

Ocean Model LICOM(LASG/IAP Climate system Ocean Model) and SODA(simple ocean data assimilation) data are used to analyse the dynamic of La Nia events in 2010.The results show that,La Ni a events in 2010 following the 2009 El Ni o events as a more special cold event,occurred in June 2010,and it’ll continue into 2011.The event is mainly excited by the western boundary reflection Kelvin wave and the eastward wind anomalies increase in the western Pacific wind anomalies,and zonal flow anomalies in the equatorial Pacific during the formation of the event also plays a very important role.
