“…Climate oscillation patterns are associated with changes in various climate variables, including temperature, wind, precipitation and pressure. Pressure gradients are driven by temperature gradients, which, in turn, drive the wind (Bjerknes, 1968; Bravo & Sarker, 2022; Shah et al, 2022). This results in the horizontal advection of warm and cold air masses, possibly forming clouds and ultimately causing positive or negative cloud radiative forcing.…”

As a high‐altitude region, the Tibetan Plateau (TP) is sensitive to climate change. Since the 1960s, the TP has experienced significant spatial‐variant warming, vital to changing the region's terrestrial ecosystem. To understand surface air temperature (SAT) regimes over the TP, we investigated their link with teleconnections using observational and reanalysis datasets from 1982 to 2019. We employed wavelet analysis, empirical orthogonal teleconnection (EOT), partial regression, canonical correlation analysis and t test. Our results indicate an asymmetrical connection between teleconnections and SAT, with Atlantic Multidecadal Oscillation (AMO) predominant over the northern TP. In contrast, the El Niño–Southern Oscillation (ENSO) is more prevalent in the southern part. The spatial variance was potentially related to windspeed, total cloud cover (TCC), net longwave radiation (NLWR), net shortwave radiation (NSWR), cloud‐forcing net longwave flux (CF‐NLWF) and cloud‐forcing net shortwave flux (CF‐NLWF) anomalies. ENSO and Pacific Decadal Oscillation (PDO) modulate cloud cover variation in the southern TP, mainly the southwest, via the monsoon and subtropical westerlies. In the north, cloud cover variation is related to the moisture transported by the AMO‐induced prevailing westerlies. The study examined the complex interplay between teleconnections, SAT and cloud radiative forcing by examining the cloud cover and radiation balance relationship. These findings contribute to understanding climate change impacts on the TP, informing climate projections and guiding adaptation strategies by elucidating the relationship between TP temperature variation and oceanic–atmospheric oscillation patterns.

“…We focused on the simultaneous occurrence of storm surges and river floods during typhoon events. Compound hazards are expected to be exacerbated with the progression of global warming, necessitating countermeasures based on technologies from various fields such as meteorology, coastal engineering, hydrology, and river engineering Frontiers in Water 15 frontiersin.org (Sarker, 2022). The compound hazard posed by storm surges and river floods may greatly alter the environments of coastal and brackish water areas.…”

The risk of high river flow and peak storm surge superimposing in the estuary of small-and medium-sized rivers can be more severe during typhoon landfalls than at other times. In this study, 30 cases of typhoon track ensemble experiments for five rivers in Mikawa Bay, Japan, were evaluated using an atmospheric-river-ocean model. The results showed that storm surges coincided with high river flows when typhoons crossed the western side of Mikawa Bay, with the highest potential observed when typhoons passed northwest of the Bay. The average time discrepancy for the five rivers between the storm surge occurrence and increased river flow in the minimum time difference case was 48 min at the river mouth. Distinct trends in the time difference between a storm surge and river flow were observed for each river mouth. The order of time differences corresponded to the drainage area scale: Toyo (188 min), Umeda (112 min), Otowa (114 min), Sana (96 min), and Yagyu (88 min). Time difference trends also varied based on the distance between the typhoon center and each river mouth. For Toyo River, storm surges and high river flows did not substantially overlap, regardless of distance. However, for medium-and small-sized rivers, the time difference increased proportionally with the distance from the typhoon. The Yagyu River showed the highest potential for compound occurrence of a storm surge and river flood because of the synchronization of storm surge peaks and high river flow peaks, with a time difference of 1–2 h for small-and medium-sized rivers within 100 km2 of the basin.

“…The implications of the water-energy-food (WEF) index are closely intertwined with climatology, as climatic factors play a fundamental role in shaping the dynamics of water, energy, and food systems (Sarker, 2022). The WEF index provides valuable insights into the interconnectedness of these systems and their vulnerabilities to climate variability and change.…”

“…The WEF index provides valuable insights into the interconnectedness of these systems and their vulnerabilities to climate variability and change. Climatology informs our understanding of how changes in temperature, precipitation patterns, and extreme weather events impact water availability, energy production, and agricultural productivity, which are key components of the WEF nexus (Sarker, 2022). By integrating climatological data and modeling approaches, the WEF index helps identify climaterelated risks and vulnerabilities within the nexus, guiding the development of policies and strategies to enhance resilience and adaptability.…”

The water-energy-food (WEF) nexus has emerged as a critical research interest to support integrated resource planning, management, and security. For this reason, many tools have been developed recently to evaluate the WEF nexus security and monitor progress toward the WEF-related sustainable development goals. Among these, calculating the WEF composite index model is critical since it can provide a quantitative approach to demonstrate the WEF nexus security status. However, the current WEF nexus index model framework needs to include the incorporation of governance indicators, neglecting the importance of governance in the WEF nexus framework. Thus, this article develops a new WEF nexus composite index model that incorporates governance indicators in each subpillar. The principal component analysis (PCA) is adopted to reduce the variables’ collinearity and the model’s dimensionality. A quasi-Monte Carlo-based uncertainty and global sensitivity analysis are applied to the index model to assess its effectiveness. Finally, the new WEF index model is applied to the 16 South African Development Community (SADC) countries as a case study. A critical synergy effect within the WEF nexus framework is identified that nations with better WEF governance ability tend to perform better in improving the WEF accessibility capability, suggesting the importance of governance in the WEF nexus security framework.
