Abstract

Bioclimatic research for the regionalization of Moldova west of the Prut River (hereinafter Moldova), focused on the use of various climate indexes, is scarce. Using 9 bioclimatic indexes (THI, Pr, Tpr, ISH, TEE, DI THOM, HUMIDEX, SSI and ISE) calculated based on statistical and cartographic methods, we identified, delineated and outlined the major characteristics of the three bioclimates of Moldova. Following our analysis, three bioclimatic regions were identified: the cold, wet and windy bioclimate, the comfortable bioclimate and the warm-dry and contrasting bioclimate. They fall broadly within the existing bioclimatic regionalization and provide new, complementary quantitative and qualitative information.

Abstract

The daily, monthly and annual variations of the tropospheric ozone in the area of Suceava municipality are described and explained by using the correlations between the ozone concentration and the local meteorological parameters. The meteorological parameters are as follows: the air temperature, the air humidity, the sunshine duration, the wind speed and direction. All parameters represent hourly datasets recorded in the interval 2004-2007. The Pearson correlation coefficients and the linear regressions were obtained for daily, monthly and yearly scales. Significant positive correlations between the O3 and the temperature and strong negative correlations between the O3 and the air humidity were found, especially between 11 a.m. and 8 p.m., during the warm season. The sunshine duration and the wind speed and direction were found to have weaker, but good positive correlation with the O3 during the same hourly interval. The weekend effect of the ozone exists in the City of Suceava too, as the reduced road traffic during the weekend causes higher concentrations of ozone. The wavelet analyses were conducted in order to further explain the variability of the ozone.

Abstract

This study addresses a current issue concerning spatial and temporal analysis of Moldova's climate resources and is intended for the use of people involved in various tourism and related activities. For researchers in the field, the study will be a source of information, allowing comparison of the results obtained for other locations, and for practitioners an indispensable working tool. The motivation for the present study resides in the sparseness and ambiguity of the analysis of climate resources for tourism included in the assessment of the natural tourism potential of Romania. We aim to improve this approach by constructing for Moldova a statistically relevant, quantitative analysis of what climate offers the tourists. To achieve the proposed objectives, we used TCI and a climate database sufficiently detailed to capture climate patterns up to ten-days time intervals. We showed that in Moldova the May-September interval is the most favorable for developing all forms of tourism. We then customized the analysis at the level of each tourism resort. Our study is among the first in this region to use such analysis and provides clear research results to those involved in tourism to improve their decision-making process. The results are very important in supporting tourism in Moldova and will contribute to raising the economic potential of the region.
