Diagnosing Ocean Feedbacks to the BSISO: SST‐Modulated Surface Fluxes and the Moist Static Energy Budget [PDF]
Journal of Geophysical Research: Atmospheres, 2019 AbstractThe oceanic feedback to the atmospheric boreal summer intraseasonal oscillation (BSISO) is examined by diagnosing the sea surface temperature (SST) modification of surface fluxes and moist static energy on intraseasonal scales. SST variability affects intraseasonal surface latent heat (LH) and sensible heat (SH) fluxes, through its influence on

Geophysical Research LettersThe Boreal Summer Intraseasonal Oscillation (BSISO) is a prominent tropical intraseasonal variability during summer. It propagates northeastward from the northern Indian Ocean to the western North Pacific and has a more complex structure than the winter ...

Northward Propagating Versus Non‐Propagating BSISO Over South Asia: Horizontal Advection Driven Moisture Mode Within a Vertically Sheared Background [PDF]
Journal of Geophysical Research: Atmospheres, 2023 AbstractThe Boreal Summer Intraseasonal Oscillation (BSISO) is a pronounced mode of tropical variability. Here, we identify two types of BSISO events, one which propagates northward over South Asia from the equatorial Indian Ocean (EIO), and the other which doesn't.

Impact of the observed SST frequency in the model initialization on the BSISO prediction [PDF]
Climate Dynamics, 2021 AbstractThe impact of the observed sea surface temperature (SST) frequency in the model initialization on the prediction of the boreal summer intraseasonal oscillation (BSISO) over the Western North Pacific (WNP) is investigated using the Beijing Climate Center Climate System Model. Three sets of hindcast experiments initialized by the observed monthly,

Topographic Effects on the Luzon Diurnal Cycle during the BSISO [PDF]
Journal of the Atmospheric Sciences, 2020 AbstractCloud-resolving simulations are used to evaluate the importance of topography to the diurnal cycle (DC) of precipitation (DCP) over Luzon, Philippines, and surrounding ocean during the July–August 2016 boreal summer intraseasonal oscillation (BSISO) event.

Propagation Characteristics of BSISO Indices [PDF]
Geophysical Research Letters, 2018 AbstractThe spatial structure and propagation of tropical intraseasonal convection anomalies diagnosed with the outgoing longwave radiation‐based Madden‐Julian Oscillation index are examined in the boreal summer and winter seasons. It is shown that the outgoing longwave radiation‐based Madden‐Julian Oscillation index represents both northward and ...

The Indian summer monsoon in MetUM-GOML2.0: effects of air–sea coupling and resolution [PDF]
Geoscientific Model Development, 2018 The fidelity of the simulated Indian summer monsoon is analysed in the UK Met Office Unified Model Global Ocean Mixed Layer configuration (MetUM-GOML2.0) in terms of its boreal summer mean state and propagation of the boreal summer intraseasonal ...

Propagating Mechanisms of the 2016 Summer BSISO Event: Air‐Sea Coupling, Vorticity, and Moisture
Journal of Geophysical Research: Atmospheres, 2021 AbstractDuring the summer of 2016, a boreal summer intraseasonal oscillation (BSISO) event was observed over Southeast Asia and the South China and Philippine seas. Precipitation anomalies associated with this event propagated northward at a speed of 0.5–1° per day from July to August.

The Boreal Summer Intraseasonal Oscillation (BSISO): A Review
Journal of the Meteorological Society of Japan. Ser. II, 2021 The boreal summer intraseasonal oscillation (BSISO) is among the most pronounced subseasonal variability in the tropics during boreal summer. Compared with its wintertime counterpart, the so-called Madden–Julian oscillation (MJO), the BSISO convection ...
