Asymmetry in space–time characteristics of Indian summer monsoon intraseasonal oscillations during extreme years: Role of seasonal mean state

A diagnostic study of the space–time characteristics of the summer monsoon intraseasonal oscillations ( MISO ) during strong monsoon ( SM ) and weak monsoon ( WM ) years is carried out to gain insight on the role of the seasonal mean states on the MISOs using long observational and reanalysis datasets. Prominent asymmetry is noted in the duration and magnitude of active‐break spells associated with MISO during SM and WM years. Such difference is...
