V zadnjem merilnem nizu, ki obsega \u00c4\u008das od 25. decembra\u00c2\u00a0do 23. januarja, je bila v mrazi\u00c5\u00a1\u00c4\u008du Dolinca najni\u00c5\u00beja temperatura -19,9 \u00c2\u00b0C izmerjena 28. decembra sredi no\u00c4\u008di. Na meteorolo\u00c5\u00a1ki postaji Zaplana, 21 m nad mrazi\u00c5\u00a1\u00c4\u008dem, se je v isti no\u00c4\u008di ohladilo do -11,1 \u00c2\u00b0C. V mrazi\u00c5\u00a1\u00c4\u008du se je ob\u00c4\u008dutneje ohladilo \u00c5\u00a1e 27. decembra dopoldne\u00c2\u00a0\u00c2\u00a0(-18,2 \u00c2\u00b0C) ter 30. decembra zjutraj in\u00c2\u00a0zve\u00c4\u008der (-17,6 \u00c2\u00b0C). Pogoste so bile no\u00c4\u008di z izrazitim padcem temperature v ve\u00c4\u008dernih urah in nadaljnim ogrevanjem do jutranjih ur. Mrazi\u00c5\u00a1\u00c4\u008de je bilo ve\u00c4\u008dji del merilnega obdobja zasne\u00c5\u00beeno, zaradi majhnih koli\u00c4\u008din novozapadlega snega pa je sneg na prisojnih pobo\u00c4\u008djih praviloma\u00c2\u00a0skopnel kmalu po sne\u00c5\u00benih padavinah. Najvi\u00c5\u00a1ja temperatura 12,8 \u00c2\u00b0C je bila v mrazi\u00c5\u00a1\u00c4\u008du ob zahodnem vetru izmerjena 17. januarja, istega dne\u00c2\u00a0 pa je bilo na meteorolo\u00c5\u00a1ki postaji nad mrazi\u00c5\u00a1\u00c4\u008dem 14,3 \u00c2\u00b0C. Tolik\u00c5\u00a1na razlika pri najvi\u00c5\u00a1ji dnevni temperaturi je za zimski \u00c4\u008das\u00c2\u00a0obi\u00c4\u008dajna, saj je mrazi\u00c5\u00a1\u00c4\u008de v primerjavi z zgornjo meteorolo\u00c5\u00a1ko postajo dlje \u00c4\u008dasa v senci, hladna tla pa \u00c5\u00a1e dodatno zavirajo ogrevanje zraka.<\/p>\n

18. decembra 2010 je bila v mrazi\u00c5\u00a1\u00c4\u008du Dvoj\u00c4\u008dek z laboratorijskim termometrom izmerjena za 4 \u00c2\u00b0C ni\u00c5\u00beja temperatura kot v sosednjem mrazi\u00c5\u00a1\u00c4\u008du Dolinca.\u00c2\u00a0Omenjena temperaturna razlika je bila povod, da je bilo v\u00c2\u00a0zadnjem merilnem nizu izvedenih nekaj\u00c2\u00a0meritev temperatur z omenjenim\u00c2\u00a0laboratorijskim termometrom. Ta je v nasprotju s\u00c2\u00a0stalnim termometrom v mrazi\u00c5\u00a1\u00c4\u008du Dolinca zelo\u00c2\u00a0primeren za terenske meritve, ugotovitve pa ka\u00c5\u00beejo, da med obema termometroma obstajajo dolo\u00c4\u008dene razlike, ki na podlagi spodnjega grafa izhajajo predvsem\u00c2\u00a0iz razli\u00c4\u008dne\u00c2\u00a0odzivnosti obeh termometrov. Laboratorijski termometer je bolj odziven od stalnega termometra in zato v \u00c4\u008dasu\u00c2\u00a0hitrega ohlajanja ka\u00c5\u00bee tudi do 3 \u00c2\u00b0C ni\u00c5\u00bejo temperaturo. Ko se temperatura ustali, to je najve\u00c4\u008dkrat v drugi polovici no\u00c4\u008di,\u00c2\u00a0so razlike med termometroma manj\u00c5\u00a1e. Ve\u00c4\u008dja odzivnost laboratorijskega termometra pride do izraza tudi v \u00c4\u008dasu ogrevanja, ko lahko ka\u00c5\u00bee celo vi\u00c5\u00a1jo temperaturo od stalnega termometra. Laboratorijski termometer se odziva na vsak pi\u00c5\u00a1, medtem ko ima stalni termometer znotraj plasti\u00c4\u008dnega ohi\u00c5\u00a1ja ve\u00c4\u008djo toplotno kapaciteto in se s tem po\u00c4\u008dasneje odziva.<\/p>\n
