The interannual cooling of the equatorial Pacific associated with La Niña events has been known to cause drought conditions over the southern tier of the U.S. by displacing the subtropical jet and storm track northward. Whereas El Niño usually terminates after one year, La Niña often persists for two years or longer, exacerbating its impacts. It is therefore critical to predict the occurrence of such events with sufficient lead time. Persistent drought driven by multi-year La Niña exerts tremendous socioeconomic impacts on the southern tier of the U.S.
This research will fill important gaps in our current understanding of La Niña-driven drought by exploring the predictability of three underlying processes: the duration of La Niña, atmospheric teleconnections driven by La Niña, and impacts of La Niña teleconnections on drought.
