• Impacts of ocean–land–atmosphere interactions on Bay of Bengal summer monsoon onset anomalies via modulating the monsoon-triggering intraseasonal oscillations (2026) · Climate Dynamics · doi

  The study identifies a research gap in understanding the mechanisms driving monsoon onset anomalies over the Bay of Bengal. The research notes that prior studies have not fully explored the role of ocean-land-atmosphere interactions in shaping monsoon onset characteristics. The study aims to address this gap by investigating the impacts of ocean-land-atmosphere interactions on Bay of Bengal summer monsoon onset anomalies.

• Impacts of ocean–land–atmosphere interactions on Bay of Bengal summer monsoon onset anomalies via modulating the monsoon-triggering intraseasonal oscillations (2026) · Climate Dynamics · doi

  The study notes that the deviations from the average onset date do not exhibit a strong linear relationship with OLR anomalies. The research acknowledges that the precise timing of monsoon onset may be shaped by the combined effects of low-level thermal contrasts and large-scale circulation anomalies, which requires further investigation.

• Analysis of the 2021 Henan extreme rainfall event from the perspective of boreal summer intraseasonal oscillation (2026) · Frontiers in Earth Science · doi

  The study highlights the urgency of understanding the multi-scale mechanisms underlying extreme rainfall events. Existing research has established connections between extreme rainfall variability and multiple atmospheric systems, but the study refines the source region distinctions within the Indian Ocean and between the South China Sea and the western North Pacific.
