Introduction The COVID-19 pandemic has caused widespread morbidity, mortality, and socio-economic disruptions worldwide. Vaccination proven to be a crucial strategy in controlling the spread of virus mitigating its impact. Objective study focuses on assessing effectiveness vaccination reducing incidence positive cases, hospitalizations, ICU admissions. presented is focused fully vaccinated population by considering data from first case reported until 20 September 2021. Methods Using multiple...
Coastal Odisha, strategically positioned between the Bay of Bengal and a vast inland landmass, is highly susceptible to climate change variability impacts. This study comprehensively examines interannual temperature its relationship with mean seasonal using 54 years homogenised surface meteorological data (1969–2022) from seven WMO-standard stations. To assess inter-annual in association precipitation, difference standard deviations (SD) two periods (e.g. 1969–1996 1995–2022) along relation...
Abstract Improving the forecasting and communication of weather hazards such as urban floods extreme winds has been recognized by World Meteorological Organization (WMO) a priority for international research. The WMO established 10-yr High-Impact Weather Project (HIWeather) to address global challenges accelerate progress on scientific social solutions. In this review, key in hazard are first illustrated summarized via four examples high-impact events. Following this, synthesis requirements,...
Background The emergence of coronavirus disease (COVID-19) as a global pandemic has resulted in the loss many lives and significant decline economic losses. Thus, for large country like India, there is need to comprehend dynamics COVID-19 clustered way. Objective To evaluate clinical characteristics patients with according age, gender, preexisting comorbidity. Patients were categorized comorbidity, data over 2-year period (1 January 2020 31 2022) considered analyze impact comorbidity on...
Malaria presents public health challenge despite extensive intervention campaigns. A 30-year hindcast of the climatic suitability for malaria transmission in India is presented, using meteorological variables from a state art seasonal forecast model to drive process-based, dynamic disease model. The spatial distribution and cycles temperature precipitation are compared three observationally-based datasets. These time series then used model, producing simulated synthetic that qualitatively...
The country wide lockdown implemented during 27th April to 14th June 2021 in order prevent the spread of COVID-19 second wave India. Effect restricted resulted improved air quality. This study focuses on analyzing spatio-temporal distribution analysis major pollutant concentration over Bangalore city inverse distance weighting (IDW) method is for spatial quantify concentrations at each location Urban Bangalore. research considers distinct periods pre-lockdown and pandemic investigate impact...
Abstract The onset of the Indian summer monsoon (ISM) represents one most dramatic transitions in regional circulation pattern. also marks beginning main rainy season for India; advanced and accurate forecast date (DOM) thus has application many sectors. Although standard deviation (σ) DOM over past hundred years is only 7 days, nearly 50% cases show large (>1σ) deviations; forecasting DOM, especially extreme nontrivial rarely attempted because poor skill GCMs long-range prediction...
Abstract There is a need to understand the onset of monsoon dynamics as date (DOM) an important parameter in framing all policy for imminent season like crop choice, sowing schedule, disaster management, power distribution etc It observed that interannual variability DOM India about 7–8 days, making it more challenge predict this at long lead. The MJO phases are linked with different convection centres and hence, influences global circulation process rainfall. In paper dynamical influence...
Abstract An effort was made to investigate the impact of assimilation microwave imager (MI) radiance observations on simulation tropical cyclones (TCs) using high‐resolution NCUM‐4DVAR method. Two numerical experiments were performed: a control experiment (CTL) (assimilated global telecommunication system [GTS] observations) and satellite (SAT) GTS plus [GMI] special sensor sounder [SSMIS] MI radiance). Assimilation is observed be capable depicting structure, track intensity storms. The...
In recent decades, vulnerability to disasters due Extreme Rainfall Events (ERE) has increased manifold over continental India during the south west monsoon season. It is a very important and challenging task for advanced forecasting of such EREs on seasonal time scales which will provide enough lead disaster management, smart agricultural practice pro-active health care example. Researchers around world are looking at ways improve skill reliability forecasts range from daily General...
An extreme temperature event (heat wave) over the state of Odisha was unique as it lasted for about 2 weeks in 3rd and 4th May 2015. There a similar severe heat wave western central month April 1998. The interesting feature recent episodic is that prevailed late pre-monsoon season with wider spread Odisha. Around 12–15 cities experienced daily maximum 45 °C during strong period, 25th −27th declared red box zone. In this study, we first analysed intense summer 2015 using India Meteorological...
