Heat waves are often termed as the silent killer and have become even more important recent studies suggest that heat wave second most devastating extreme weather events in terms of human deaths losses. It is also been largely realised by scientific community it not just high temperatures which responsible for gruesome effect but several other meteorological parameters play a vital role aggravating impact causing much damages. In view above attention community, forecasters well disaster managers has shifted to take into account different like maximum minimum temperatures, relative humidity, wind speed, duration/spell its intensity stress. this background, study undertaken an attempt quantify on regions India summer months (March, April, May June). individual parameter their cumulative studied based data 30 years (1981-2010) 300 stations.

CMIP6 models informed summer human thermal discomfort conditions in Indian regional hotspot

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Авг. 2, 2023

The frequency and intensity of extreme thermal stress conditions during summer are expected to increase due climate change. This study examines sixteen models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) that have been bias-adjusted using quantile delta mapping method. These provide Universal Thermal Climate Index (UTCI) for seasons between 1979 2010, which regridded a similar spatial grid as ERA5-HEAT (available at 0.25° × resolution) bilinear interpolation. evaluation compares summertime climatology trends CMIP6 multi-model ensemble (MME) mean UTCI with ERA5 data, focusing on regional hotspot in northwest India (NWI). Pattern Correlation Coefficient (between ERA5) values exceeding 0.9 were employed derive MME UTCI, was subsequently used analyze models.The climatological demonstrates significant over NWI region, ERA5. Both show rising trend NWI. temporal variation analysis reveals experiences higher compared rest India. number days is also increasing major Indian cities according MME. Future projections under different scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5) indicate an discomfort throughout twenty-first century. projected rates approximately 0.09 °C per decade, 0.26 0.56 respectively. Assessing near (2022-2059) far (2060-2100) future, all three suggest rise intense heat (UTCI > 38 °C) Notably, predict could reach deadly levels high-emission (SSP5-8.5) scenario. findings underscore urgency addressing change its potential impacts human well-being socio-economic sectors.

Rising climate disasters underscore the overlooked impact of heat stress on health and productivity in densely populated Southeast Asia, particularly vulnerable coastal areas like India's. This study Indian Sundarbans employs surveys social network analysis to explore effects, community adaptation, support networks. Recognizing significance, it views resilience as a blend agency, wisdom, The research unveils rural adaptive behaviours, co-occurring responses, use for solutions.

Опубликована: Апрель 1, 2024

Extreme heat-precipitation events, such as heatwaves and extreme precipitation, can have substantial impacts on the population, particularly in urbanized watersheds. However, few studies investigated individual compound causing much valuable information loss for watershed climate risk management. This study focuses Pearl River Basin (PRB), a highly area southern China, aims to predict changes population exposure events. To achieve this, ranked ensemble global model (GCM) was used generate projections heatwaves, sequential coincident heat waves precipitation extremes (SHWPs CHWPs) under three future scenarios (SSP-RCPs). The main findings of are follows: Precipitation represent increasing days intensity all across PRB. Towards end 21st century, SSP5-8.5 scenario predicts that will last ten times longer than historical records. Comparing two types we conclude century see near-term high SHWPs long-term CHWPs Furthermore, both five hotspot cities PRB (i.e., Guangzhou, Dongguan, Foshan, Shenzhen, Huizhou) face higher These share common characteristics: key economic development, coastal, densely populated. provide insight into management other tropical subtropical basins.

Global warming is a pressing problem that necessitates immediate action. This phenomenon particularly affecting the quality of life in larger cities due to population growth and human mobility. Understanding space-time variability heat stress various locations will face future therefore crucial for us. Taking into account aforementioned facts, current study examined evolution Hi index four European capitals - Berlin, Madrid, Paris, Rome during months July, August, September between 2008, 2012, 2017. The Space Agency (ESA) UrbClim climate model was used collect environmental data. Furthermore, Local Climatic Zones (LCZ) classifications land use/cover change (LULC) coverages were improve evaluation extrapolation results. According findings, studied areas experienced significant increases temperatures 2008 cities' average increase 0.31 °C per decade, with southern experiencing greater intensity northern less intensity. When comparing spatiotemporal different zones, discovered more impervious fewer green are vulnerable potential stress. As result, urban developments can be able create spaces resistant stress, improving people's life.

Spatiotemporal link between El Niño Southern Oscillation (ENSO), extreme heat, and thermal stress in the Asia–Pacific region

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Март 28, 2024

Abstract Climate change is closely monitored and numerous studies reports increasing air temperature weather extremes across the globe. As a direct consequence of increase global temperature, increased heat stress becoming threat to public health. While most climate epidemiological focus on explain risks, strain can be predicted using comprehensive indices such as Universal Thermal Index (UTCI). The Asia–Pacific region prone thermal high population densities in impose health risk. This study evaluated UTCI trends between 1990 2019 found significant for whole while increases are not pronounced mainly northern part region. These results indicate that even though increasing, risks when assessed may alleviated by other factors. associations El Niño Southern Oscillation (ENSO) was seasonal level strongest regional responses were during December-January (DJF) March–May (MAM).
