20.500.12556/RUL-165057 Padavinski gradienti v alpskih dolinah na primeru izbranih dolin Julijskih Alp Čeprav imajo Alpe med vsemi svetovnimi gorstvi najgostejšo mrežo padavinskih postaj, je poznavanje padavinskih razmer marsikje še vedno pomanjkljivo. To nam dokazujejo študije na mikro ravni, ki v gorskih pokrajinah potrjujejo domneve o precej večjih padavinskih gradientih kot na nižinskih območjih. V gorah je zaradi večje vetrovnosti in večjega deleža snežnih padavin problematična tudi natančnost meritev. To pomeni, da na območjih z največjo količino padavin o njihovi količini vemo mnogo manj kot bi si želeli, pomanjkljiva informacija o količini padavin pa vodi v številne napake, kot na primer pri oceni vodne bilance in pri oceni nevarnosti snežnih plazov. Prispevek govori o izsledkih meritev količine padavin v alpskih dolinah, na podlagi katerih smo izračunali horizontalne padavinske gradiente. Although the Alps have the densest network of precipitation stations among world's mountain areas, detail knowledge of precipitation conditions is still lacking. This is evidenced by microlevel studies, which confirm assumptions of much higher precipitation gradients in mountain areas than in lowland areas. Due to higher windiness and higher proportion of solid precipitation the measurements of precipitation in mountains is affected by high measurement error. This leads to insufficient knowledge about precipitation amount, which further leads to many uncertainties, such as in assessing the risk of avalanches. The paper discusses the results of measurements of precipitation in the Alpine valleys, on the basis of which we calculated horizontal precipitation gradients. The uncertainty of scale parameter evaluated on a single station dataset is much higher than the uncertainty of the location parameter. We reduced this uncertainty of the scale parameter with mapping the ratio of scale and location parameters as we assume almost stationary values of the ratio on a regional level. Kriging steps used were the same as for location parameter. Gridded values of scale parameter were then calculated by multiplying the maps of location parameter and the ratio. klimatogeografija lokalno podnebje padavine Slovenija Julijske Alpe climatogeography local climate mountain climate Slovenia Julian Alps true false false Slovenski jezik Angleški jezik Neznano 2024-11-21 12:55:48 2024-11-21 12:55:55 2024-11-22 03:58:07 0000-00-00 00:00:00 2020 0 0 Str. 70-76 [Št.] 12/13 2020 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 551.5(497.4) 1855-7791 33902595 http://www.smd.v-izdelavi.si/glasilo/ 1 2af20977-a7ff-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196004 RAZ_Ogrin_Matej_2020.pdf RAZ_Ogrin_Matej_2020.pdf 1 BDA2998E43BEAB7575A43B49602434DB 21d3eb58e1cb4aa4f2a5cd49637e46a71c6708b376b045882910daff37f77366 806b4874-a800-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=196005 Filozofska fakulteta 0 0 0
