Trends in air temperature and atmospheric precipitation in Botoşani between 1961 and 2017

Air temperature and precipitations are major factors affecting the climate of a certain place. They define the basic matrix of the climate, and their evolution are of interest for the whole of both human and scientific community. The purpose of the present study is to highlight the sign and the magnitude of the trend in the air temperature at Botoşani city weather station for the whole period 1961-2017, and for both its major subdivisions (1961-1990 and 1991-2017, respectively) throughout different temporal subsets (from the level of an average year to the level of a month). Besides air temperature, we determined the evolutive trend in the amount of rainfall using a similar methodology (based mainly on the Mann- Kendall and t tests). Following our approach, we showcased the thermal and pluviometric reality at Botoşani, which is in a continuous change (as for the temperature values) or in a relatively dynamic balance (with respect to the amount of precipitations). More precisely, at Botoşani, against an annual average temperature of 9.4°C and an annual average of precipitations of 569.0 mm, after the year 1961 and mostly after 1990, the tendency was positive, which indicates an increase in air temperature. From a thermal point of view, considered annualy, seasonally and by warm and cold seasons (excepting autumn, with an insignificant increase), air temperature displayed a representative increase in value over the assessed period (1961-2017). On the whole, the annual temperature values increased by 0.32°C / decade, which presents a maximum statistical significance. Annual amount of rainfall increased over the period 1961 – 2017 by 4.46--5.35 mm/ decade, but this was not statistically significant

Some of the bioclimatic peculiarities of thermal water resorts located in western Romania

The paper captures some of the spatial differences and similarities, as well as the temporal peculiarities of the bioclimate of the Băile Felix, Moneasa, Geoagiu and Băile Herculane thermal water resorts, which were monitored during field observations between November 2015 and July 2017, within the project PN-II-RU-TE-2014-4-2900. To outline the temporal succession of different bioclimatic conditions in the studied resorts, we were able to calculate the thermohygrometric index (THI) and the DI Arakawa Discomfort Index (DIA) based on temperature and humidity data measured with field iButton sensors. The collected field data allowed us to calculate only these two bioclimatic indices, since they can be obtained using only the air temperature and humidity measured values. In this study, we preferred to use at least two bioclimatic indices, which would allow for a comparison between their bioclimatic values and ratings, rather than to employ a single index without having benchmark data for assessing its values. The values and temporal variability of the indices showed contradictory results for the four thermal water resorts. The annual and diurnal intervals of bioclimatic comfort and discomfort indicated by the two indices are not identical in terms of timing and duration. Taking into account both these findings and the results obtained in a series of previous studies, we consider the THI values more reliable compared to DIA, which visibly contradicts the bioclimatic conditions of the four Romanian tourist resorts. Therefore, based on the data provided by THI only, we highlighted the favorability of these locations for general and health tourism and the high degree to which the bioclimate with sedative characteristics complements and supports the balneary cure and treatment provided in the specialized treatment centers of the respective resorts
