Data recovery and climate reconstruction are an important support for climate change research, as they provide information from periods and areas with sparse meteorological networks. Various sources are currently in use for obtaining valuable evidence of past climate, such as ship logs, diaries, books, monastery documents. This study exploits newsp...

This study presents the meteorological information spanning the last two decades of the end of 19th century (1880-1900) extracted from three Romanian newspapers (România Liberă, Gazeta de Transilvania and Foaia Poporului). It describes the characteristics of the newspaper data included in the database, it offers and overview of the meteorological n...

The metadata are defined as the informations behind the data. The purpose of the metadata in meteorological activity is to represent where, when, how and by whom meteorological data has been obtained, colected and recorded. Ideally, a comprehensive metadata base should contain records of all changes that have occured throughout the entire period in...

A two-step interpolation framework is proposed for the first time for computing sub-daily (6-hour) precipitation maps over Romania, over 36 years (1975-2010), using meteorological and ancillary data. In the first step, the monthly climatology maps were constructed. Here, the auxiliary predictors were quantified with the help of multi-variate geosta...

Recent climate change is characterized (among other things) by changes in the frequency of some meteorological phenomena. This paper deals with the long-term changes in various precipitation types, and the connection between their variability and cloud type frequencies, at 11 meteorological stations from Eastern Romania over 1961–2008. These statio...

This paper overviews the development of the solar radiation monitoring network in Romania, stressing the milestones, the current configuration and utility. In 1879, Ștefan C. Hepites, the most prominent figure and pioneer of the Romanian meteorology, founded a meteorological station in his courtyard from Regală Street, in respect of all the recomme...

Brilliant minds of humanity have tried to understand both the heavenly events and the earthly phenomena. Scientist Nicolae Donici was one of the first researchers from the Bessarabian space who, due to his intense passion for astronomy, understood the deeper implications that cosmic processes can have on the aspect of the weather (and therefore cli...

Six meteorological variables from all available Romanian weather stations were tested for trends at annual scale over the 1961-2013 period. Changes in annual air temperature, precipitation, sunshine hours, nebulosity, relative humidity and wind speed were investigated. The Mann-Kendall nonparametric trend test was used in order to find statisticall...

The paper presents a country-wide trend analysis in seasonal air temperature, precipitation, sunshine hours and wind speed, over the 1961-2013 period. Changes in annual temperature and precipitation extremes are also investigated by means of 14 indices recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI). The air temperat...

This paper presents an astroclimatological study of meteorological data on relative humidity, dew-point temperature, air temperature, wind speed and barometric air pressure recorded at four Romanian locations (Baisoara, Rosia Montana, Semenic, Ceahlau) and the Nordic Optical Telescope (NOT) located at the Observatorio del Roque de Los Muchachos (OR...

Commencer du mois d’aout 2006 dans le réseau météorologique national de la Roumanie les mesurages du rayonnement solaire global et de la durée effective d’ensoleillement ont été effectués en même temps par les traducteurs et les appareilles classiques. Le system classique pour les mesurages du rayonnement solaire global est représenté par les actin...

Around the world, several scientific projects share the interest of a global network of small Cherenkov telescopes for monitoring observations of the brightest blazars - the DWARF network. A small, ground based, imaging atmospheric Cherenkov telescope of last generation is intended to be installed and operated in Romania as a component of the DWARF...

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...

The goal of the study is to analyse both the spatial and the temporal distribution of freezing rain events in Romania and Germany from the point of view of classical climatology: the frequencies of occurrence of freezing rain events are analysed in order to get a general picture of their spatial and temporal distribution, without analysing single e...

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...

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...

Precipitation is one of the main climatic elements which determines the availability of water resources and has considerable impact on different aspects of human activity. The present analysis is based on monthly precipitation totals from 22 meteorological stations situated in the Danube River lower basin both in Romania and Bulgaria. These station...
