Non-linear intensification of monsoon low-pressure systems by the BSISO [PDF]
Weather and Climate Dynamics, 2022 More than half of the rainfall brought to the Indian subcontinent by the summer monsoon is associated with low-pressure systems (LPSs). Yet their relationship with the boreal summer intraseasonal oscillation (BSISO) – the dominant intraseasonal forcing ...

Diagnosing Ocean Feedbacks to the BSISO: SST‐Modulated Surface Fluxes and the Moist Static Energy Budget [PDF]
Journal of Geophysical Research D: 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

Increased global subseasonal whiplash by future BSISO behavior. [PDF]
Sci AdvPropagation patterns of 30- to 90-day boreal summer intraseasonal oscillation (BSISO) markedly affect subseasonal prediction. We show that global warming significantly alters BSISO propagation by Coupled Model Intercomparison Project Phase 6 projections.

Propagation pathways of Indo-Pacific rainfall extremes are modulated by Pacific sea surface temperatures [PDF]
Nature Communications, 2023 Intraseasonal variation of rainfall extremes within boreal summer in the Indo-Pacific region is driven by the Boreal Summer Intraseasonal Oscillation (BSISO), a quasi-periodic north-eastward movement of convective precipitation from the Indian Ocean to ...

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,

Biases in Indian Summer Monsoon Precipitation Forecasts in the Unified Model and Their Relationship With BSISO Index [PDF]
Geophysical Research Letters, 2021 AbstractThis study shows that the Boreal Summer Intraseasonal Oscillation (BSISO) dominates the Indian summer monsoon low‐precipitation bias in the Met Office Unified model. Analyzing a recent 9‐year period (June, July, August only), it is found that the precipitation bias is dominated by break and break‐to‐active transition BSISO phases, while some of

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 ...

Propagating Mechanisms of the 2016 Summer BSISO Event: Air‐Sea Coupling, Vorticity, and Moisture
Journal of Geophysical Research D: 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.

Design evaluation of automatic bearing offset adjustment for marine propeller shaft [PDF]
Scientific ReportsConventional marine propeller shaft alignment is performed under predetermined conditions of dry-docking or afloat with fully submerged propellers. It may overlook high-risk scenarios of partial propeller immersion or transient conditions during sailing ...

Environmental Research: ClimateThe Boreal Summer Intraseasonal Oscillation (BSISO) and Madden–Julian Oscillation (MJO) are two significant intraseasonal modulators of tropical weather. The effects of these two oscillations are mostly limited to particular seasons and regions.
