Intraseasonal variability of vegetation water content in India driven by monsoon hydrometeorology
Understanding how Indian vegetation during the summer monsoon (June–September) responds to intraseasonal variability, with hydrometeorological stressors like vapor pressure deficit (VPD) and soil moisture (SM), is crucial and yet it is not well-explored. Existing studies often rely on correlation analysis and occasionally use causal inference, but they tend to overlook the intraseasonal scales of monsoon variability and their impact on vegetation…
A prototype early warning system for diarrhoeal disease to combat health threats of climate change in the asia-pacific region
Ongoing climate variability and change are increasing the burden of diarrhoeal disease worldwide. Meaningful early warning systems with adequate lead times (weeks to months) are needed to guide public health decision–making and enhance community resilience against health threats posed by climate change. Toward this goal, we trained various machine-learning models to predict diarrhoeal disease rates in Nepal (2002–2014), Taiwan (2008–2019), and Vi…
Decadal preference of seasonal Enso transition through a southern hemisphere climate mode
El Niño Southern Oscillation (ENSO) is the leading interannual coupled climate mode in the tropical Pacific. The seasonal transition of ENSO from boreal winter to the following summer can significantly affect the global climate. One of the major hurdles in understanding the seasonal transition of ENSO is the spring predictability barrier. Here, we show that ENSO’s seasonal transition is modulated by a multidecadal climate mode of boreal spring se…
Hysteresis in seasonal land-atmospheric interactions over India and its characteristics across croplands and forests
Satellite-derived vegetation optical depth and soil moisture (SM) data reveal the critical role of the soil-vegetation continuum in storing rainwater during the Indian Summer Monsoon and supporting evapotranspiration (ET) during the dry non-monsoon season. During the non-monsoon drier period, the climatologically estimated spatial mean of ET exceeds precipitation input, a phenomenon known as the soil–vegetation capacitor effect, which is pivotal …
Global Population Exposed to Extreme Events in the 150 Most Populated Cities of the World
Climate change driven increases in the frequency of extreme heat events (EHE) and extreme precipitation events (EPE) are contributing to both infectious and non-infectious disease burden, particularly in urban city centers. While the share of urban populations continues to grow, a comprehensive assessment of populations impacted by these threats is lacking. Using data from weather stations, climate models, and urban population growth during 1980-…
Food insecurity and compound environmental shocks in Nepal
Increased cyclone destruction potential in the Southern Indian Ocean
The present study examines the role of the Southern Indian Ocean (SIO) warming on the cyclone destruction potential or Power Dissipation Index (PDI) during two contrasting periods of 1980–1998 and 1999–2016. The PDI in the SIO during 1999–2016 is found to have doubled compared to the same during 1980–1998. PDI was computed using the tropical cyclone track data in the SIO region for cyclone category three and above. The increasing trend in PDI dur…
Detecting the net effect of flooding on infectious diarrheal disease in Anhui Province, China
Though a number of studies have shown positive relationships between flooding events and infectious diarrhea, there is a paucity of rigorous evidence regarding the net effect of flooding on diarrhea incidence, controlling for existing pre-trends and meteorological confounders. The study treats the 2016 catastrophic flood event in Anhui Province, China as a natural experiment using a difference-in-differences design with propensity score matching …
Pollutants control the process networks of urban environmental-meteorology
The dynamics of interactions between the environmental and the meteorological variables in an urban region is extremely complex due to continuously evolving coupled human–natural processes in an urban setting. We attempt to understand the same with the networks of variables using information theory, known as process network. We monitored local meteorological variables at half-hourly scale using an eddy covariance observation system combined with …
We are very far from using earth system models for managing a public health crisis
A comprehensive India-wide social vulnerability analysis
The impacts of hazard events such as extreme rainfall, heatwaves, and droughts are substantial and represent an increasing threat over India. Effective adaptations to these hazards require an in-depth understanding of their physical and socioeconomic drivers. While hazard characteristic models have been substantially improved, compelling evidence of the spatio-temporal analysis of social vulnerability (SoV) throughout India are still lacking. Her…

Shift in Indian summer monsoon onset during 1976/1977
The Indian summer monsoon rainfall (ISMR) contributes nearly 80% of the annual rainfall over India and has a significant influence on the country's gross domestic product through the agricultural sector. Onset of the ISMR displays substantial interannual variability and controls the crop calendar and hence the agricultural output. This variability is traditionally linked to sea surface temperature (SST) anomalies over the tropical Pacific Ocean. …
