Abstract

V magistrskem delu smo obravnavali pogostost, dolžino in intenziteto vročinskih valov ter njihovo sovpadanje s sušnimi obdobji na petih meteoroloških postajah po Sloveniji (Ljubljana - Bežigrad, Maribor - Tabor, Murska Sobota - Rakičan, Celje - Medlog in Novo mesto). Vročinski val je po definiciji Slovenskega meteorološkega društva obdobje, ko povprečna dnevna temperatura zraka vsaj 3 zaporedne dni preseže mejno vrednost dnevne povprečne temperature zraka na določenem območju. Vseh pet obravnavanih postaj spada v območje celinskega podnebja, zato smo za vseh 5 postaj uporabili mejno vrednost 24 °C. V statistični analizi temperaturnih podatkov od leta 1961 do 2015 ugotavljamo naraščanje pogostosti, dolžine in intenzitete vročinskih valov. Predstavljamo tudi pozitiven trend dni s povišano povprečno dnevno tempreaturo zraka. Ekstremno visoke temperature zraka se v zadnjih letih v Sloveniji pojavljajo pogosteje, najbolj izstopata leti 2003 in 2013. Sušna obdobja opredeljujemo kot obdobje, ko je vodna bilanca v tleh negativna. V statistični analizi povprečnih vodnih bilanc ugotavljamo, da je trend negativen na vseh obravanavanih postajah. Sušna obdobja se v zadnjih letih v Sloveniji pojavljajo pogosteje, najbolj izstopata leti 1993 in 2003. Daljši in intenzivnejši vročinski valovi v kombinaciji s sušo imajo negativne posledice na kmetijsko pridelavo in delavce v kmetijstvu.

Secondary title: Time matching of dry periods and heat waves in Slovenia
Secondary abstract: In the master thesis we investigate the frequency, length and intensity of heat waves and their coincidence with drought periods at five meteorological stations across Slovenia (Ljubljana - Bežigrad, Maribor - Tabor, Murska Sobota - Rakičan, Celje - Medlog in Novo mesto). Definition of a heat wave by Slovenian Meteorological Society is a period, in which the average daily air temperature for at least 3 consecutive days exceeds the limit value of the daily average air temperature in a given area. All five stations belong to the continental climate zone, so we used a 24 °C limit for all stations. Statistical analysis of temperature data from 1961 to 2015 showed increase in the frequency, length and intensity of heat waves. We also found a positive trend of days with an average daily air temperature increase. Extremely high air temperatures in Slovenia have been more frequent in recent years, but most of them occurred in years 2003 and 2013. Dry periods are defined as the period when the water balance is negative. In the statistical analysis of water balance we note that the trend is negative for all stations. Drought periods have been more frequent in Slovenia in the recent years,, the driest years were 1993 and 2003. Longer and more intense heat waves, combined with drought periods, have negative consequences on agricultural production and agricultural workers.
