Značilnosti izrednih padavinskih dogodkov v Sloveniji v zadnjih 20 letih

Zupančič, Katarina (author), Pogačar, Tjaša (mentor)

Diplomska naloga obravnava izredne padavinske dogodke v Sloveniji v zadnjih 20 letih. Izreden padavinski dogodek nastopi takrat, ko na določeni lokaciji pade več padavin, kot je običajno za tisto lokacijo, pomembno pa je tudi kdaj in v kolikšnem času se zgodi. Namen dela je ugotoviti značilnosti izrednih padavinskih dogodkov, tudi po letnih časih. Vir podatkov za analizo je bil arhiv izrednih vremenskih dogodkov na spletni strani ARSO. Pri izboru dogodkov je bilo upoštevanih več kriterijev, kot so povratne dobe in gmotna škoda. Izredni padavinski dogodki so se skozi obravnavano obdobje, od 2006 do 2025, pojavljali različno, skladno z letnimi časi. Spomladi je veliko različnih snežnih dogodkov, sledijo pozebe in obilne padavine. Poleti zaradi nestabilnega ozračja prevladujejo neurja. To je tudi letni čas z največ izrednimi dogodki. Ob sredozemski ciklogenezi jeseni prevladujejo obilne padavine. Pozimi prevladujejo snežni dogodki. To je letni čas z najmanj izrednimi dogodki. Večini dogodkov so skupne sledeče sinoptične razmere: prisotnost višinske doline, prehodi front, ciklonska območja v Sredozemlju in jugozahodni zračni tok. Poleti prevladujejo padavine konvektivnega nastanka. Ena glavnih omejitev analize je premajhno število meteoroloških postaj, s katerimi ne moremo zajeti vseh padavinskih dogodkov, čeprav si pri ocenah lahko pomagamo z radarsko sliko.

• Title: Characteristics of extreme precipitation events in Slovenia in the last 20 years

Abstract

Thesis addresses extreme precipitation events in Slovenia in the last 20 years. Extreme precipitation event happens, when on some location falls more precipitation than it is usual for that location. It is also important, when precipitation event happens and in which timeframe. Purpose of the thesis was to determine characteristics of extreme precipitation events, in different seasons. Data source was the archive of extreme weather events on web page of Slovenian Environment Agency (ARSO). In selection of the events was taken in consideration if event caused damage and how high were return periods. Extreme precipitation events from 2006 to 2025, were different in seasons. In spring there is more snow events, with frost and heavy rainfall. At summer we have many storms because of atmospheric instability. This is also the season with most extreme precipitation events. Heavy rainfalls are frequent as a result of Mediterranean cyclogenesis in autumn. In winter we have mostly snow events. Most events have next similar characteristics: upper-level trough, weather fronts, cyclon areas in Mediterranean and southwestern airflow. In summer we have convective precipitation. One limitation of recording and analysing extreme precipitation events is also insufficient number of meteorological stations, and we cannot record every precipitation event that has happened.
