Abstract: Change in significance and multidecadal variability of the Northern Hemispheric winter MJO during 1948?2006 is examined using NCEP?NCAR reanalysis data. Variation of the MJO power relative to a red background is estimated ...

Abstract: ealistic simulation of different modes of atmospheric variability ranging from diurnal cycle to interannual variation in global climate models (GCMs) depends crucially on the convection trigger criteria. In this study, ...

Abstract: The three-dimensional structure, horizontal and vertical propagation characteristics, and convection–circulation coupling of the convectively coupled westward-propagating mixed Rossby–gravity (MRG) waves are examined by ...

Abstract: significant fraction of interannual variability (IAV) of the Indian summer monsoon (ISM) is known to be governed by ?internal? dynamics arising from interactions between high-frequency fluctuations and the annual cycle. ...
