Article
Four climate parameters (i.e. maximum, mean and minimum air temperature and precipitation amount) from 10 regional climate models, provided by the EURO-CORDEX initiative, are adjusted using as reference the ROCADA gridded dataset. The adjustment was performed on a daily temporal resolution for the historical period (1971–2005), as well as for clima...

Respiratory infectious diseases are highly influenced by climate and feature seasonality, whose peak is December to February in the Northern Hemisphere. SARS-COV-2 produced consistent debate regarding the relationship between its emergence and weather conditions. Our study explored these conditions, expressed by three main parameters-ultraviolet ra...

The Southern Carpathians (Romania) are one of the highest, steepest and most massive sectors of the Carpathian Mountains, with a strong imprint of the Pleistocene glaciation, which are widely affected by a broad spectrum of natural hazards (avalanches, rock wall weathering and landslides, flash floods). This paper focuses on the detection of recent...
Article
Full-text available
The aim of this study was to evaluate the frequency and severity of drought over the arable lands of Romania using the Normalized Difference Drought Index (NDDI). This index was obtained from the Moderate Resolution Imaging Spectro-Radiometer (MODIS) sensor of the Terra satellite. The interval between March and September was investigated to study t...
Article
Full-text available
The Landsat 8 satellites have retrieved land surface temperature (LST) resampled at a 30-m spatial resolution since 2013, but the urban climate studies frequently use a limited number of images due to the problems related to missing data over the city of interest. This paper endorses a procedure for building a long-term gap-free LST data set in an...

The response of the cryosphere to a warmer climate is spatially diversified and requires accurate monitoring and understanding. The study analyses the changes in snow cover phenology (the first and last snow cover days - FSC and LSC), duration (SCD, SCDmax) and snow-free days (SFD) in Romania, which includes wide parts of the Carpathian Mountain ra...
Article

Study region: A plain region covering 8000 km2 in extreme north-eastern Romania in which two groundwater levels are identified, near the surface (1.5 m) and in-depth (4.5 m) respectively. Study focus: The statistical relationship between climate conditions and underground water resources was assessed by means of correlation analysis and autoregres...
Article
Full-text available
The management of groundwater resources must take into account their variation trends. In this sense, 3 statistical methods were used to identify seasonal and annual groundwater level trends: Mann-Kendall test (MK), Innovative Analysis Method (ITA) and Spearman's Rho test (SR). Each method was applied for 5 time series (one annual and four seasonal...
Conference Paper
Snow water equivalent (SWE) and snow depth (SD) is estimating using Snow 17 model for several meteorological mountain station from Romania. The model uses air temperature as the sole index to determine the energy exchange across the snow-air interface. In addition to temperature, the only other input variable needed to run the model is precipitatio...
Article
Full-text available
The paper presents the temporal variability of surface ozone (O3) and its precursors (oxides of nitrogen - NOx) from January 2012 to December 2015. In the same time, this study is aimed to explore the influence of the weather elements on these two major atmospheric pollutants in the area of Iași city. The maximum record of nitrogen oxides reached d...

The increasing world population constantly seeking comfort and safety has triggered intense urbanization. Cities generate the Urban Heat Island (UHI), which is one of the major concerns for urban development, particularly under the rising occurrence of climate hazard events, such as heat waves (HWs). The overall scope of the project is to substantiate the capacity of the cities in Romania to adapt to temperature hazards associated with climate change challenges, through an interdisciplinary approach envisaging both the actual reaction of the cities and the long-term preparedness and plans. The analysis focuses on county-capital cities in Romania. http://synuhi.meteoromania.ro/
