Northward Prpogating BSISO over South Asia: connection between moisture advection and vortex tilting

2023
The mechanism behind the northward propagation of the Boreal Summer Intraseasonal Oscillation (BSISO) over South Asia is still elusive, though many theories have been proposed to explain it. In this study, column- integrated moisture budget and vorticity budget analyses are used on NCEP-NCAR1 and ERA5 reanalyses data to understand the dominant ...

ENSO Modulation of Interannual Variability in the First Occurrence of MJO and BSISO Events

Journal of Geophysical Research: Atmospheres
This study investigates the interannual variability in the first occurrence dates of the first Madden Julian Oscillation (FMJO) and the first Boreal Summer Intraseasonal Oscillation (FBSISO) events over the Indian Ocean during 1940–2022.

Objective Classification of Asymmetric Modes of the Boreal Summer Intraseasonal Oscillation over the Western North Pacific and Their Divergent Impacts on Eastern China Precipitation

Atmosphere
The boreal summer intraseasonal oscillation (BSISO) over the western North Pacific (WNP) exhibits significant phase asymmetry, but a systematic classification of its asymmetric modes and their regional climatic impacts remains insufficiently explored ...

Subseasonal Predictability Sources for Three Successive Episodes of a Prolonged Extreme High Temperature Event over the Yangtze River Basin in the Summer of 2022

Journal of Climate
In the summer of 2022, the Yangtze River Basin (YRB) experienced the most intense and prolonged extreme high temperature event since 1961, featured by three successive episodes of June 18–29 (P1), July 6–17 (P2) and August 3–26 (P3).

The Relative Role of Different Mechanisms of Northward‐Propagating Intraseasonal Oscillation Over the Indian Ocean, the South China Sea, and the Western North Pacific

International Journal of Climatology
Previous studies have proposed several well‐recognised mechanisms for the northward‐propagating boreal summer intraseasonal oscillations (BSISOs), while their relative roles tend to be qualitatively analysed.
