Abstract

Geostatistika spada u granu geomatematike koja se bavi analizom prostornih podataka
u svrhu kvantificiranja i modeliranja njihove prostorne korelacije. U geostatistici, a
katkad uz određene prilagodbe i u meteorologiji, računalni programi poput Surfera,
ArcGIS-a itd. koriste se za analizu prostorne distribucije meteoroloških elemenata.
Prostornu distribuciju meteoroloških elemenata moguće je grafički prikazati izradom
variograma i konturnih karata u računalnom programu Surfer.
Osnovni cilj ovog istraživanja je proučavanje prostorne raspodjele srednjih dnevnih
temperatura zraka u Republici Hrvatskoj (RH) u dva 30 - godišnja klimatska razdoblja:
1961. – 1990. i 1991. – 2020. Podaci o vrijednostima srednjih dnevnih temperatura zraka
na 30 promatranih meteoroloških postaja, preuzeti su iz Državnog hidrometeorološkog
zavoda Republike Hrvatske (DHMZ).
Variografska analiza srednjih godišnjih temperatura zraka u primorskoj, nizinskoj i
gorskoj regiji RH provedena je u računalnom programu Surfer. Izrađene su konturne karte
pomoću kojih će se pokušati ustvrditi postoji li porast ili opadanje godišnjih prosjeka
temperature zraka između dva navedena razdoblja. Rezultati geostatističkog modela
uspoređeni su s rezultatima regionalnog klimatskog modela (RegCM).
Također, testirana je hipoteza o statističkoj značajnosti trenda porasta srednje dnevne
temperature zraka za meteorološku postaju u Ogulinu za razdoblje 1961. – 2021.

Abstract (english)

Geostatistics is a branch of geomathematics that deals with the analysis of spatial data
for the purpose of quantifying and modeling their spatial correlation. In geostatistics, and
sometimes with certain adjustments in meteorology, computer programs such as Surfer,
ArcGIS, etc. are used to analyze the spatial distribution of meteorological elements. The
spatial distribution of meteorological elements can be displayed graphically by creating
variograms and contour maps in the Surfer computer programme..
The main goal of this research is to study the variability of mean annual air
temperatures in two 30-year-long periods: 1961 – 1990 and 1991 – 2020 in the territory
of the Republic of Croatia. The data on mean daily air temperatures at 30 observed
meteorological stations were taken from the Croatian Meteorological and Hydrological
Service (CMHS).
A variographic analysis of annual average air temperatures in the Republic of Croatia's
coastal, lowland and mountainous regions was carried out in the Sufer computer
programme. Contour maps were created to determine whether there was an increase or
decrease in annual average air temperatures between the two mentioned periods. The
results of the geostatistical model created in Surfer were compared with the Regional
Climate Model (RegCM) results.
Also, a hypothesis about the statistical significance of the trend for an average daily
increase in an air temperature at the meteorological station in Ogulin in the period from
1961 to 2021 was tested.
