Ob koncu februarja 2010 je pri\u00c5\u00a1lo do tako imenovane\u00c2\u00a0pomladne odjuge. Gre za kombinacijo de\u00c5\u00beevne odjuge (taljenje sne\u00c5\u00bene odeje\u00c2\u00a0zaradi de\u00c5\u00beja), dnevne odjuge (taljenje zaradi dnevnih temperatur nad 0\u00c2\u00b0C) in prisotnosti vla\u00c5\u00bene in\u00c2\u00a0tople zra\u00c4\u008dne mase (taljenje zaradi odsotnosti no\u00c4\u008dnega zmrzovanja). Kljub izraziti odjugi pa\u00c2\u00a0se je na Zaplani sne\u00c5\u00bena odeja talila zelo po\u00c4\u008dasi. 19.februarja je\u00c2\u00a0padlo na obstoje\u00c4\u008do sne\u00c5\u00beno odejo kar\u00c2\u00a080mm de\u00c5\u00beja, naslednji dan je sne\u00c5\u00beilo in sne\u00c5\u00bena odeja se je odebelila na okoli 55cm. V nadaljevanju\u00c2\u00a0so temperature le redko padle pod 0\u00c2\u00b0C. V dveh dneh je de\u00c5\u00beevalo, pogosto je pihal zmeren jugozahodni veter in temperatura je dvakrat presegla 10\u00c2\u00b0C. Do 28.februarja se je sne\u00c5\u00bena odeja sesedla in stalila zgolj za 25cm,\u00c2\u00a0zasne\u00c5\u00beena pa so bila celo obse\u00c5\u00bena prisojna pobo\u00c4\u008dja med Spodnjo in Zgornjo Zaplano.\u00c2\u00a03.marca je bilo \u00c5\u00a1e slabih 20cm snega.\u00c2\u00a0Zakaj se je sne\u00c5\u00bena odeja kljub tako mo\u00c4\u008dni odjugi\u00c2\u00a0talila po\u00c4\u008dasneje od pri\u00c4\u008dakovanj?<\/p>\n
Sneg se najhitreje tali ob visokih temperaturah\u00c2\u00a0in vetru, ki piha v dneh z visoko vla\u00c5\u00benostjo zraka. Ob dolo\u00c4\u008denih pogojih, kakr\u00c5\u00a1ni so bili tudi ob koncu februarja 2010, pa se sne\u00c5\u00bena odeja tali precej po\u00c4\u008dasneje.\u00c2\u00a0Za taljenje je pomembna vrsta snega. Sneg, ki na tleh le\u00c5\u00bei\u00c2\u00a0dlje \u00c4\u008dasa, se ves \u00c4\u008das preobra\u00c5\u00bea. Struktura snega\u00c2\u00a0postane zrnasta, sneg se poseda in prepu\u00c5\u00a1\u00c4\u008da do tal vedno ve\u00c4\u008d de\u00c5\u00beevnice.\u00c2\u00a0Ob de\u00c5\u00benih padavinah\u00c2\u00a0se sne\u00c5\u00beni odeji pove\u00c4\u008da gostota, ob morebitnem kasnej\u00c5\u00a1em\u00c2\u00a0zmrzovanju pa postane sne\u00c5\u00bena odeja zelo odporna na taljenje, saj je za taljenje ledu potrebno zelo veliko toplotne energije. Do kasnej\u00c5\u00a1ega\u00c2\u00a0zmrzovanja sne\u00c5\u00bene odeje\u00c2\u00a0pride pogosto zaradi dnevnega taljenja in ob\u00c4\u008dasnega no\u00c4\u008dnega\u00c2\u00a0zmrzovanja. Za opisano februarsko\u00c2\u00a0odjugo je bilo tudi\u00c2\u00a0zna\u00c4\u008dilno, da je bila v dneh z visokimi temperaturami zelo nizka vla\u00c5\u00benost zraka. Ob nizki vla\u00c5\u00benosti zraka povr\u00c5\u00a1ina sne\u00c5\u00bene odeje izpareva v vodno paro, pri tej fazni spremembi vode se iz okolice porablja toplota in tik pri sne\u00c5\u00beni odeji se ohranja precej hladnej\u00c5\u00a1a plast zraka, ki ohranja sneg suh in\u00c2\u00a0prepre\u00c4\u008duje\u00c2\u00a0mo\u00c4\u008dnej\u00c5\u00a1e taljenje.\u00c2\u00a0Tako je\u00c2\u00a0v\u00c2\u00a0dneh s temperaturami nad 10\u00c2\u00b0C sne\u00c5\u00bena odeja upadla zgolj za centimeter ali dva.<\/p>\n","protected":false},"excerpt":{"rendered":"
