Abstract: Based on a recently released, high-resolution reanalysis dataset for the North American region, the intraseasonal variability (ISV; with a time scale of about 20 days) of the North American monsoon (NAM) is examined. The ...

Abstract: The characteristic features of the boreal summer intraseasonal oscillation (BSISO) during its reinitiation period are studied using NCEP?NCAR reanalysis. Based on these observations and with the aid of an anomalous atmospheric ...

Abstract: his study illustrates that observed modulations of tropical cyclone (TC) genesis over the eastern Pacific (EPAC) by large-scale intraseasonal variability (ISV) are well represented in a recently developed high-resolution ...

Abstract: The spatial and temporal structures of the northward-propagating boreal summer intraseasonal oscillation (BSISO) are revealed based on the analysis of both the ECHAM4 model simulation and the NCEP?NCAR reanalysis. The BSISO ...

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: n this study, evidence of the strong modulation of the convectively coupled Kelvin wave (CCKW) activity by the Madden?Julian oscillation (MJO) is presented, with a particular focus over the South America and tropical ...

Abstract: he relationship between a model?s performance in simulating the Madden?Julian oscillation (MJO) and convectively coupled equatorial wave (CCEW) activity during wintertime is examined by analyzing precipitation from 26 ...
