英文摘要: During the 2010-2011 La Niña and Ningaloo Niño, excessive precipitations in the Maritime Continent and Indonesian-Australian Basin caused surface waters to freshen by 0.3 practical salinity unit in the southeast Indian Ocean. The low-salinity anomalies are observed to be carried westward by the Indonesian throughflow and the South Equatorial Current and transmitted into the poleward flowing eastern boundary current, the Leeuwin Current, along the Western Australian coast. Low-salinity anomalies contribute to about 30% of the anomalous increase of the southward Leeuwin Current transport during the evolution of the 2010-2011 Ningaloo Niño, resulting in unprecedented warming off the coast of Western Australia. Episodical freshening of the Leeuwin Current has been observed at the Rottnest coastal reference station of Western Australia during extended La Niña conditions over the past several decades; low-salinity anomalies at the station during the 2010-2011 Ningaloo Niño are comparable with strong historical events. Key Points Excessive precipitation drives freshening of the Indonesian throughflow Low-salinity anomalies are carried southward by the Leeuwin Current Low-salinity anomaly contributes to intensify the Leeuwin Current transport © 2015.
