Analiza temperaturnih vsot v Sloveniji z vidika klimatskih nihanj : diplomska naloga = Growing degree days analysis from climate oscillations point of view : graduation thesisDečman, MartinaKlima našega planeta se spreminja tudi zaradi povečanega učinka "tople grede". V zadnjem stoletju se je v Sloveniji povprečna temperatura zraka v vegetacijskem obdobju povečala za 0,5°C in še ... narašča. Do leta 2050 naj bi se po napovedih WMO povečala vsaj za 2°C. Višja temperatura v obdobju rasti vpliva na podaljšano dolžino potencialne vegetacijske dobe ter večjo vsoto temperatur v tem obdobju. V nalogi je podana klimatološka analiza nastopov dejanskih spomladanskih in jesenskih temperaturnih pragov, dolžin obdobij med pragovi in aktivnih temperaturnih vsot nad 0°, 5° in 10° za štiri kraje v Sloveniji v obdobju 1961-1990 in za Ljubljano v obdobju 1901-1990. Za Ljubljano je podana primerjava vrednosti za tridesetletna obdobja z dolgoletnim povprečjem. V Ljubljani se dolžini obdobij s povprečno dnevno temperaturo zraka nad 5° in 10°C daljšata, obdobje stemperaturo zraka nad 0°C se krajša. Spomladanski temperaturni pragovi so v zadnjih tridesetih letih nastopili prej in jesenski kasneje kot v začetku stoletja, razen temperaturnih pragov 0°C. Vse tri temperaturne vsote se v zadnjih sto letih povečujejo, še posebno v zadnjem obdobju. Trendi za tridesetletna obdobja so manj zanesljivi zaradi vplivov nepredvidljivih nihanj klimatskih podatkov. Trendi obravnavanih klimatskih elementov v zadnjih tridesetih letih so v večini krajev nasprotni opisanim trendom v Ljubljani. V prihodnje pričakujemo daljše rastno obdobje, hitrejšo rast in dozorevanje rastlin. Temu bo morala biti prilagojena izbira novih temperaturnih sprememb. Problem bo izbrati ustrezni čas setve, še posebno, če se pojav poznih spomladanskih in zgodnjih jesenskih slan ne bo spremenil.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
