Short summary
Short summary
The observed winds in the upper atmosphere over the equator have alternating easterly and westerly regions that descend towards the lower atmosphere before dissipating, with a period of approximately 28 months. This is known as the Quasi-Biennial Oscillation (QBO). The QBO is known to influence remote regions of the atmosphere. This paper details the results of multi-model experiments where the QBO is nudged towards the observed QBO allowing the assessment of these remote connections.

Short summary
Short summary
An event-based experimental framework is developed to model typhoon disasters by coupling meteorological, river discharge, and storm-surge models. The framework is distinguished by the use of multi-model and multi-initial-condition ensembles. Typhoon Hagibis (2019) intensifies under future warming, leading to greater flooding and storm surges. By broadening prediction uncertainties, the multi-model framework enables more comprehensive and reliable assessments of future typhoon disaster risks.

Short summary
The authors performed verification on the relationships between extreme monsoon rainfall over Japan and Pacific sea surface temperature variability in the “database for Policy Decision-making for Future climate changes” (d4PDF). Observations showed widespread weak relationships between hourly extremes and the warming mode but reversed relationships between daily extremes and the decadal variability mode. Biases in d4PDF could be explained by the monsoon's slower movement over Japan in the model.

Short summary
We simulated the Taisho (1914) eruption of Sakurajima volcano under various weather conditions to show how a similar eruption would affect contemporary Japan in a worst-case scenario. We provide the dataset of projected airborne ash concentration and deposit over all of Japan to support risk assessment and planning for disaster management. Our work extends previous analyses of local risks to cover distal locations in Japan where a large population could be exposed to devastating impacts.

Short summary
This study provides an insightful view on possible teleconnections between the stratospheric Quasi-biennial oscillation (QBO) and global monsoon system. It is observed that the QBO has dynamical teleconnections with different regional monsoons where prominent dynamical circulations prevail, and primarily modulates these circulations, thereby influencing the associated precipitation patterns. The findings would enable us to improve long-range forecasting for global monsoon system.
This study provides an insightful view on possible teleconnections between the stratospheric...
