Wave activities characteristics during a sudden sharp drought–flood turn event in 2011 in East China
Abstract The sudden turn from drought to flood (STDF) is an extreme climate event that frequently occurs over the middle and lower reaches of the Yangtze River Basin (MLYR) in China. This study investigates the role of the intraseasonal oscillation (ISO) in a STDF event in 2011 over the MLYR and ana...
