THERMAL COMFORT TRENDS AND VARIABILITY IN THE CROATIAN AND SLOVENIAN MOUNTAINS

Mountain meteorological stations played an extremely important role in weather forecasting in the past because they were the only available data source on meteorological conditions several hundred metres above the sea level. Nowadays they are mainly used to estimate the climatic variations and the climate change trends in the environment that is not under the direct influence of the local anthropogenic factors. Two mountain meteorological observatories were chosen to illustrate climatic and bioclimatic trends and variability, Zavižan in Croatian Dinaric Alps and Kredarica in Slovenian Julian Alps. Both have the same monitoring protocol and similar instruments. Because of their unchanged surrounding since time of establishment the data from both observatories are extremely valuable for studying changes in sensitive mountain ecosystems in both countries. Data from the period 1955-2004 were used to assess mountain climatic and bioclimatic variability and trends in Croatia and Slovenia. Results point at the significant increase in the thermal bioclimate index (PET) based on the human energy balance models. At both sites the increase is mainly caused by temperature changes

POJAVA CEREBROVASKULARNOG INZULTA U OVISNOSTI O TIPOVIMA VREMENA I FRONTAMA

U radu je analizirana uvjetna vjerojatnost pojavljivanja cerebrovaskularnih inzulta kad se pojavio određeni tip vremena, kao i učestalost cerebrovaskularnih inzulta u 7-dnevnom razdoblju n ± 3 dana oko centralno smještenog dana s prolazom hladne ili tople fronte. Pokazalo se je da su cerebrovaskularni udari najčešći u tipovima vremena s niskim tlakom zraka (doline i ciklone) te u situacijama kad nad naše područje iz velikih udaljenosti dolaze zračne mase bitno drugačijih karakteristika od prevladavajućih - zimi N, NE tipovi, a u proljeće i jesen S, SW tipovi vremena. Učestalost CVI veća je u dane s hladnom frontom, a zimi i u proljeće i 1-2 dana uoči njega, a ljeti dan nakon prolaza hladne fronte

Meteorological parameters in the design of thermal protection of buildings

Analizirani su relevantni meteorološki parametri za 15 lokacija u Hrvatskoj za razdoblje 1961-1990. To su: srednje mjesečne, sezonske i godišnje temperature zraka, najniža i najviša srednja dnevna temperatura zraka s podacima o prekoračenju u danima, standardna vanjska temperatura zraka, globalno zračenje, difuzno zračenje, maksimalne dnevne količine oborina, srednje mjesečne, sezonske i godišnje količine oborina te vrijednosti relativne vlažnosti zraka i tlaka vodene pare.Relevant meteorological parameters for 15 locations in Croatia are analyzed for the 1961 - 1990 period. These parameters are: mean monthly, seasonal and annual air temperatures, minimum and maximum average daily air temperature with overstepping values in days, standard outside air temperature, global radiation, diffuse radiation, maximum daily precipitation, mean monthly, seasonal and annual precipitation, relative humidity of air and water vapor pressure

CLIMATIC CONDITIONS ON THE ISLANDS OF CRES AND LOŠINJ WITHIN THE GLOBAL CLIMATE CHANGES

Most climate models anticipate a surface air temperature rise of several degrees Celsius during the next century supposing carbon dioxide (CO2) concentration in the atmosphere is going to double. As a consequence of the Earth\u27s surface warming, a sea level rise of several tens of centimeters can be expected in the same period. These changes will not have the same intensity during the whole year, they will depend on the season and the different parts of the world. In this paper, the influence of these changes on the islands of Cres and Lošinj is considered. A higher increase in annual temperature could be expected (up to 5°C) at the end of the 21th century. A significant change in annual precipitation is not very probable. However, a decrease in precipitation during summer and autumn and an increase during winter and spring has been established. A change in other climatic elements can also be expected

A HIGH RESOLUTION TEMPERATURE CLIMATOLOGY FOR THE GREATER ALPINE REGION (GAR)

The Greater Alpine Region (the GAR) covering the area between 4-19°E and 43-50°N and an altitude range between 0 and more than 4000 m asl. offers a challenging climate worth to be studied in any detail. However, it is surprising that up to now no comprehensive Alpine Temperature Climatology covering the whole region is existing. To overcome this deficiency as a first step we want to produce monthly temperature maps for this region in spatial resolution as high as possible. The period under investigation will be 1961-1990. In this paper we will describe the first steps of our initiative as well as the further plans
