The article analyses the values of daily, monthly and annual precipitation measured during period 1948–2019 at following four stations: (1) Split, (2) Hvar, (3) Lastovo (4) Zagreb. first three stations are located in a Mediterranean climate, while station Zagreb is continental climate. aim performed to detect non-stationarity (trends, jumps, seasonality) regime three-time scales (day, month, ye...
abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
The determination of air temperature is important in the energy balance calculation, hydrology and meteorological studies. In this regard, the limited number of meteorological stations is one of the serious problems for air temperature determination on a large spatial scale. The remote sensing technique by covering large areas and using updated satellite images might be appropriate for estimati...
The permanence of rainfall shortage compared with the long-term average of meteorological droughts, reduces river flow, groundwater level and hydrological droughts. To quantify the drought, several indexes has been defined. In this study, two drought indexes, including standardized precipitation index (SPI) and standardized streamflow index (SSI), were used for meteorological and hydrological d...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
meteorological stations usually contain some missing data for different reasons.there are several traditional methods for completing data, among them bivariate and multivariate linear and non-linear correlation analysis, double mass curve, ratio and difference methods, moving average and probability density functions are commonly used. in this paper a blended model comprising the bivariate expo...
Precooling a building overnight during the summer is a low cost practice that may provide significant help in decreasing energy demand and shaving peak loads in buildings. The effectiveness of precooling depends on the weather patterns at the location, however research in this field is predominantly focused in the building thermal response alone. This paper proposes an analytical tool for asses...
26 Links between spatial and temporal variability of Planetary Boundary Layer (PBL) 27 meteorological quantities and existing land use patterns are still poorly understood due to 28 the non-linearity of air-land interaction processes. This study describes the results of a 29 statistical analysis of meteorological observations collected by a network of ten 30 Automatic Weather Stations (AWSs). T...
