Abstract: A rare and intense tropical weather event, named “Madar 22” affected large areas of the Kingdom of Saudi Arabia and neighboring Gulf countries during July and August 2022. This study aims to assess the hydrological impacts of the event on both surface and groundwater resources, and its implications for water resources management in the Kingdom.... More

Abstract: An attempt has been made to study the horizontal momentum flux and vertical energy flux associated with baroclinic airflow over northeast region of India. The northeast region of India features two prominent orographic barriers: the Assam-Burma Hills (ABH) and the Khasi-Jaintia Hills (KJH). This paper presents a three-dimensional (3-D) model for mountain waves, applied to... More

Abstract: A better understanding of atmospheric dynamics and improvement of regional weather and climate models require accurate measurement and analysis of atmospheric variables such as temperature, pressure, and wind velocity across altitudes. In this study, we present such results from a series of high-altitude balloon missions conducted by the Indian Centre for Space Physics (ICSP). These... More

Abstract: The formation of a tropical cyclone (TC) involves complex dynamic and thermodynamic processes. Understanding the role of mid-level vortices in the genesis of TCs over the NIO is crucial for improving TC forecasting. This study aims to enhance the field of meteorology by providing insights into these genesis processes. We utilized the National Centre for... More

Abstract: This study analyzes the statistical behavior of PM2.5 concentrations in Brasília using advanced probabilistic and time series modeling to support air quality management and extreme event forecasting. The methods applied include Generalized Extreme Value (GEV) distributions, Bayesian inference with Log-Normal distribution, ARIMA models, and quasi-Gaussian approaches. Model performance was evaluated through statistical metrics such as... More

Abstract: Friagem events in the southwestern Brazilian Amazon including their changes, variability and climatological features during the 1979–2020 period were examined. The incursion of polar origin cold air mass into the region during austral autumn and winter, which leads to the abrupt drop of the air temperature, characterizes the friagem event. Sixty-five friagem events were identified during... More

Abstract: Understanding the aerosol-cloud relationship is critical for reducing uncertainties in climate projections, especially over regions that experience complex aerosol dynamics from both natural and anthropogenic sources. This study aims to investigate how aerosols influence cloud properties under varying water vapor conditions over nine urban and rural subregions of the Eastern Mediterranean, disentangling the seasonal and...

Abstract: The increasing adoption of electric vehicles (EVs) is regarded as a key strategy for mitigating urban air pollution in rapidly developing regions like South Asia. However, the effects of EV penetration on various pollutants—especially secondary pollutants like ozone—remain complex and context-dependent. This study investigates pollutant trends in Ludhiana, India, from 2013 to 2025, focusing on... More

Abstract: This study investigates the spatial and temporal variability of the Total Column Ozone (TCO) across three Brazilian biomes—Cerrado, Pantanal, and Atlantic Forest—between 2005 and 2020. Satellite-derived TCO data from the Ozone Monitoring Instrument (OMI) were used to assess monthly, seasonal, and interannual variations. Linear and polynomial regressions were applied to identify trends and variability, while... More
