Najprej je bil zaposlen na Inštitutu za geografijo SAZU, nato na Inštitutu za raziskovanje krasa SAZU, aprila 1966 se je zaposlil na...
Zaradi velikih razlik v višini padavin med slovenskimi pokrajinami je kot pokazatelj njihove spremenljivosti v obdobju 1991–2020 uporabljena srednja relativna variabilnost. Letna variabilnost je analizirana za 174 padavinskih postaj, giblje se v razponu med 8 in 18 %. Letne padavine so najbolj variabilne v zahodni in severozahodni Sloveniji. Sezon...
V letu 2019 je Univerza v Ljubljani praznovala 100-letnico delovanja. Ob ustanovitvi sta bili za geografijo predvideni dve stolici. Zaradi kadrovskih težav so se predavanja iz geografije začela spomladi 1920. Z ustanovitvijo univerze se je slovenska geografija institucionalizirala in vzpostavila stik s takrat modernimi geografskimi tokovi v razvite...
V prispevku so prikazane spremembe povprečne temperature zraka in višine padavin za reprezentativne meteorološke postaje posameznih podnebnih tipov v Sloveniji za obdobje 1991-2020 v primerjavi z obdobjem 1961-1990. Predstavljene so tudi glavne poteze podnebne tipizacije za zadnje klimatološko obdobje in nakazane spremembe, ki jih je ta doživela v...
V prispevku je predstavljena podnebna tipizacije Slovenije za klimatološko obdobje 1991–2020. Izhodišče za členitev je bila Köppen-Geigerjeva klasifikacija, ki pa je pregroba za prikaz vseh podnebnih specifik Slovenije. Z upoštevanjem dodatnih temperaturnih in padavinskih kriterijev smo slovensko podnebje razčlenili na štiri osnovne tipe z devetimi...
This article presents a climate classification for Slovenia for the climatological period 1991-2020. It is based on the Köppen-Geiger classification, but this classification is too coarse-grained to show all the specific climatic features of Slovenia. Taking into account additional temperature and precipitation criteria, we divided the Slovenian cl...
ali doneski k slavi in zgagi vojvodine geografske IZVLEČEK Ni kaj dosti za izvleči. Znano je, da smo vsi po malem zemljepisci, da se znašamo nad tvarino, ki obstaja v nas in okoli nas, imamo pa težave po ljudsko povedati, s čim se ukvarjamo in, zakaj je to dobro. Takisto je prepoznano, da bolehamo za raznimi bipolarnimi motnjami, beri: dualizmi. Ze...

The cities of Ljubljana, Trieste and Zagreb are proximate in terms of distance but differ in terms of geographical and climatic conditions. Continuous meteorological measurements in these cities began in the mid-19 th century. The 100-year trends of changes in mean annual and seasonal air temperatures for these cities are presented here, evaluating...
Long instrumental records of meteorological variables such as temperature and precipitation are very useful for studying regional climate in the past, present, and future. They can also be useful for understanding the influence of large-scale atmospheric circulation processes on the regional climate. This paper investigates the monthly, winter, and...
The paper discusses trends in the changing of air temperatures and precipitation in the higher, southeastern part of the Kras. The sub-Mediterranean climate of the hinterland is here combined with continental climate therefore the characteristics of climate changes slightly differ from the trends along the shore of the Gulf of Trieste. Due to the l...
Prispevek obravnava trende spreminjanja temperature zraka in padavin v višjem, jugovzhodnem delu Krasa. Zaledno zmerno sredozemsko podnebje se tu prepleta s celinskim podnebjem, zato se značilnosti spreminjanja podnebja nekoliko razlikujejo od trendov ob obali Tržaškega zaliva. Zaradi manjšega vpliva morja je trend segrevanja ozračja izrazitejši, š...

O podnebnih in vremenskih razmerah na Slovenskem pred začetkom rednih in neprekinjenih meteoroloških meritev je razmeroma malo znanega. Nekaj več informacij je za 17. st., še posebej za drugo polovico, v kateri je deloval kranjski polihistor J. V. Valvasor. Njegove zapise o vremenu in podnebju lahko dopolnimo tudi z zapisi ljubljanskega kronista J....
Not much is known about the climate and weather conditions on the Slovenian territory before regular and continuous meteorological measurements began to be performed. Some more information exists for the 17th century, particularly for its second half when J. W. Valvasor was active as a renowned Carniolan polymath. Valvasor's records about weather a...
In the first part of the article problems of physical geographical divisor) of Slovenia and the most important so far existing physical geographical divisons are presented. In the second part a new physical geographical divison of our country in 47 regions is presented. This is a continuation of the divison from the year 2004 which was agreed in th...
From the time before uninterrupted meteorological measurements began, only the climate in the hinterlands of Trieste Gulf is better known in comparison with other Slovenian regions. Weather chronicles from that time do not render possible to make up complete reconstructions of the climate, yet they provide us with an insight into the climatic event...
Climate and weather conditions in the Slovenian lands from the time before regular and continuous meteorological measurements began are but poorly known. Investigations in this field began as late as the beginning of the 17 th century; particularly the second half of this century, when the polymath Janez Vajkard (Johann Weichard) Valvasor and the L...
Typical of the second half of 19th century, at the global level - and consequently also on the territory of Slovenia - is a trend of gradual warming of the atmosphere, which has been particularly explicit since the year 1980. Not only the atmosphere but a/so the oceans are getting warmer, and other change has been observed in the climate system, wh...
Insolation of the Earth's surface is subject to change, depending on astronomic, atmospheric and terrestrial factors. The paper presents the changing temperatures of seasons in the medium and high geographical latitudes. They result from seasonal change in the incoming solar radiation energy because of the earth's revolution, inclination of the ear...
Warmer winters have brought the ski area Španov vrh near Jesenice in decline. New climate conditions put plans of conventional ski tourism in a different point of a view. The article analysis trends of air temperature and snow conditions in winter months at Planina pod Golico to fnd out if weather conditions assure development of classical winter t...
The paper presents the basic topoclimatic features of the littoral zone in Slovenian Istria which result from general climate features and specific local conditions. The most widely spatially spread topoclimatic units arise from differences in insolation and the combination of local landforms and land use. They are presented on the map at a scale o...
Vse toplejše zime so smučišče Španov vrh nad Jesenicami pahnile v nazadovanje in zimski turizem na Planini pod Golico na rob propada. Pri morebitnem oživljanju zimskega turizma se v luči novih podnebnih razmer postavlja vprašanje smotrnosti vlaganja v klasični zimski turizem.
