Abstract:
Ground-level zone (O₃) is a key air pollutant influenced by air pollutants and meteorological conditions. Understanding the causal relationships between ground-level ozone and (i) meteorological factors and (ii) other air pollutants is critical for two reasons: 1) accurately predicting and forecasting and 2) air quality management. This research investigates the causality and...
Abstract:
The problem of seasonal and diurnal variations of ozone concentrations and their relationship with meteorological parameters is investigated for Craiova, Romania. By analysing hourly and seasonal trends, this study aims to identify peak ozone formation periods and the key environmental factors influencing their variability. The dataset comprises hourly ozone and meteorological data,...
"How tornadoes form?" is a seemingly simple question, yet the answer is quite complex. Much remains to be discovered about tornadoes, tornadogenesis and the forecasting of tornadoes. One way of improving our current understanding about tornadoes is to develop detailed tornado climatologies. In this study, we are expanding the existing Romanian tornado database by meticulously documenting...
Global warming is a phenomenon threatening humanity. Can we fight it? It appears that humanity has accepted as true the notion that the phenomenon is caused by the release of greenhouse gases as a consequence of human activity, and that if we stop emitting them, global warming will cease. For this purpose, the world allocates approximately $ 3 trillion annually. Are these funds being directed...

Desert-dust events in the United Arab Emirates (UAE) frequently cause sharp increases in particulate matter (PM) pollution, posing significant risks to public health and aviation safety.
This study focuses on next-day forecasting of daily PM₂.₅ and PM₁₀ concentrations and their corresponding Air Quality Index (AQI) categories across Abu Dhabi Emirate.
We are using five years of air quality...
Air pollution in Brasov city is a subject of high interest for authorities and researchers due to its impact on human activities as well as due to the specific conditions found in this region – from geographical conditions affecting the pollutant dispersion to the sustained high air pollution levels. Of particular concern were the infringement procedures from the European Commission against...
Abstract
Indoor exposure to radon and thoron in healthcare environments, such as hospitals and clinics, is a significant concern due to the potential health risks to patients and staff. This study aims to measure and analyze the activity concentrations of radon and thoron and calculate the values of the effective dose received from patients and staff in selected healthcare facilities...
Severe convective events are often driven by specific synoptic patterns, which influence the initiation, further development, and movement direction of the cloud structures that generate them. The days of June 13, 2024, and May 6 and 8, 2025, brought such phenomena: heavy rainfall over short periods of time, frequent lightning, and in some areas, strong wind gusts and medium to large hail...
Human activities have negatively affected more than 70% of the Danube wetlands. Their restoration will benefit ecosystem services, including wetland and river biodiversity and carbon sequestration. The European Commission’s Mission “Restore our ocean and waters by 20230” targets not only Danube and Black Sea areas, but also meets a number of the UN sustainable development goals (SDGs), such as...
