Article
Full-text available
Drought is a climatic extreme event causing environmental damages that limit plant development and crop yields, with significant economic and societal impacts. Mitigation and adaptation measures to drought are the responsibility of both farmers and government entities requiring integrative management plans and strategies which account for the local...
Article
Full-text available
Crop loss due to drought is a complex issue, because it changes according to the drought intensity and duration, and the developmental stage of the plants when drought occurs. In order to assess the drought-induced decline in crop harvest, drought variability and the yield sensitivity of winter wheat, maize, sugar beet, and sunflower to drought dur...

Regional climate models (RCMs) are important tools used for downscaling climate simulations from global scale models. In project CECILIA, two RCMs were used to provide climate change information for regions of Central and Eastern Europe. Models RegCM and ALADIN-Climate were employed in downscaling global simulations from ECHAM5 and ARPEGE-CLIMAT un...

EURO-CORDEX is the European branch of the CORDEX initiative aiming at producing ensemble climate simulations based on multiple dynamical and empirical-statistical downscaling models forced by multiple global climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5). This paper presents a validation study for the high resolution...
Article
The relationship between the seasonal modes of interannual variability of a multiscalar drought index over Europe and the large-scale atmospheric circulation and sea surface temperature (SST) anomaly fields is investigated through statistical analysis of observed and reanalysis data.

Article
Availability of long-term and high-quality instrumental climate records is still insufficient and the rich heritage of meteorological surface observations is largely underexploited in many parts of the world. This is particularly striking over the Greater Mediterranean region (GMR), where meteorological observations have been taken since the 18th c...
Article
We assess the changes in drought conditions during summer in the Republic of Moldova based on the Standardized Precipitation Index (SPI) calculated from monthly precipitation data simulated by the regional climatic model RegCM3. The RegCM simulations were conducted at a horizontal resolution of 10 km in the framework of EU-FP6 project -CECILIA. The...

This paper analyses the observed spatiotemporal characteristics of drought in the Czech Republic during the growing season (April to September) as quantified using the Standardised Precipitation Evapotranspiration Index (SPEI) on various time scales. The SPEI was calculated for various lags (1, 3, 6, 12, and 24 months) from monthly records of mean...

This paper analyzes the characteristics of spatial evolution of the standardized precipitation evapotranspiration index (SPEI) at various time scales during the growing period (April-September) over the Czech Republic. The SPEI was calculated from monthly records of mean temperature and precipitation totals measured at a dense network of 184 climat...
Conference Paper
Full-text available
This study presents a detailed assessment on drought variability and its driving factors in the Republic of Moldova during the second half of 20th century and the first decade of the 21st century. Due to the availability of relatively long continuous series, we chose the Chisinau climatological station as a representative station for testing the St...

The study presents the observed variability and changes in precipitation regime in the Danube river lower basin, which is situated along both sides of the border between Bulgaria and Romania. The research is based on monthly precipitation totals recorded at 22 meteorological stations from Bulgaria and Romania. The investigated period is 1961-2007 o...
Article
Full-text available
Climate change is expected to affect not only the means of climatic variables, but also their variabilities(1,2) and extremes such as heat waves(2-6). In particular, modelling studies have postulated a possible impact of soil-moisture deficit and drought on hot extremes(7-11). Such effects could be responsible for impending changes in the occurrenc...
Book
De peste doua decenii, o stafie generala bantuie lumea: cea a incalzirii globale si a schimbarilor climatice majore! Afirmat stiintific si recunoscut oficial prin tratate, legi ori rapoarte de cercetare, fenomenul se incearca sa fie ingradit, pe cat posibil, in amplificare ori efectele sale, prognosticate a deveni catastrofale numai in perspectiva...
Conference Paper
The climate change occurred in the last decades is characterized, among other things, by the changes in the frequency and trend of the meteorological phenomena. The purpose of this paper is to analyze the climatic characteristics of some of the precipitation types: rain, rain shower, snow, snow shower, sleet, sleet shower and the connection of thei...
Article
We analyze 100-150 years-long temperature and precipitation records from 14 meteorological stations in Romania, in connection with long-term trends in solar and geomagnetic activities. The comparison of solar (sunspot number) and geomagnetic (aa index) parameters with the mean air temperature over the Romanian territory, at interdecadal timescales,...
Article
Changes of 10 core indices selected from a comprehensive set of extreme indices calculated in the framework of the EC-FP6 Project CECILIA is analyzed. These indices are relevant for assessing different aspects of both precipitation (intensity, frequency) and temperature (magnitude and frequency) extremes in the simulations performed with RegCM at 1...

Article
Snow cover represents an important climatological parameter for the specialized analysis because it can provide useful information regarding the climatological evolution of one region, taking into account the variability of the climate. The latest years brought milder winters for Romania. The number of days with snow cover and the depth of snow cov...
Article
In the context of climate change scenarios runs the outcome of different soil water content forcing depend on different time-scales interactions. A set of 10-year summer season (June, July, August) simulations with the RegCM in which the soil water content has been forced by fixed values (mean, above-mean, bellow-mean) is analyzed. The spatial doma...
Article
Results of the comparison of the simulations performed with RegCM and RegCM-beta version at 10 km resolution over Romania domain centered at 46N;23.5E for the period 1961- 2000 are discussed. The models were driven by ERA-40 reanalysis and validated against CRU observation data set and observations at selected station from Romania both for temperat...
Article
During the last decades a growing number of heat waves have been observed in Romania during summer. The current index used in the National Meteorological Administration in Bucharest for quantifying human comfort is a temperature-humidity index (ITU). The heat warning is issued by the National Forecasting Center in two stages: warning stage 1 (alert...

The relationships between decadal (>5-year period) observed winter precipitation (PP) variability over Europe and atmospheric circulation and sea surface temperature (SST) during the period 1950–1995 are investigated. More than 48% of the decadal precipitation variability is described by two modes: a meridional dipolar pattern (high PP over norther...

Conference Paper
One of the most important problem in climate research is the quality of data. Several statistical tests have been developed for detecting inhomogeneities in time series of climate elements. Some tests depend on metadata while other techniques are purely statistical and may be used for homogeneity studies including series where station history is po...
