H\u00e4r kommer en sammanfattning av december 2022. V\u00e4derdata f\u00f6r \u00e5rets decemberm\u00e5nad \u00e4r h\u00e4mtade fr\u00e5n min privata v\u00e4derstation h\u00e4r i F\u00e5gelfors.

Fr\u00e5n 2013 och fram\u00e5t \u00e4r det min egna, privata v\u00e4derstation som levererar siffrorna. Nuvarande \u201dnormalperiod\u201d som anv\u00e4nds att j\u00e4mf\u00f6ra mot, \u00e4r \u00e5ren 1991-2020, men jag redovisar ocks\u00e5 \u00e5ren 1931-2022 i mina diagram i min redog\u00f6relse nedan.<\/p>\n\n\n\n

I stapeldiagrammet ovan, ser vi att december 2022 blev en blandning av b\u00e5de riktigt kallt v\u00e4der i mitten av m\u00e5naden, och rej\u00e4lt milt i slutet av m\u00e5naden. Medeltemperaturen hamnade p\u00e5 -1,6 grader, vilket \u00e4r 0,9 grader kallare j\u00e4mf\u00f6rt mot nuvarande ”normalperiod” 1991-2020. I fjol hade vi ocks\u00e5 en kall decemberm\u00e5nad, d\u00e5 var medeltemperaturen -2,7 grader. Annars har decemberm\u00e5naderna varit milda ett antal \u00e5r, man f\u00e5r g\u00e5 tillbaka till 2012 och 2010 f\u00f6r att hitta n\u00e5gra kallare decemberm\u00e5nader. Vi har ocks\u00e5 haft n\u00e5gra rej\u00e4lt milda decemberm\u00e5nader p\u00e5 senare \u00e5r, bl.a. 2015 och 2020. Jag l\u00e4gger in n\u00e5gra stapeldiagram nedan, s\u00e5 blir det l\u00e4tt \u00f6versk\u00e5dligt att se och j\u00e4mf\u00f6ra december 2022 mot n\u00e5gra olika referensperioder.<\/p>\n\n\n\n

Nederb\u00f6rd har vi f\u00e5tt 51 mm denna decemberm\u00e5nad. Det \u00e4r 16% mera j\u00e4mf\u00f6rt med referensperioden 1991-2020. Vi har haft m\u00e4tbart sn\u00f6t\u00e4cke i 15 dagar, det st\u00f6rsta sn\u00f6djupet var 11 cm n\u00e5gra dagar runt den 15:e. Jag visar i diagrammen nedan i n\u00e5gra olika tidsperioder hur decembernederb\u00f6rden sett ut.<\/p>\n\n\n\n

Det var vinterm\u00e5nad nummer 1 av 3 i sammanfattning. Nu g\u00e5r vi in i januari 2023, som inleds med mildv\u00e4der och regn. Om en m\u00e5nad vet vi hur det blev under \u00e5rets f\u00f6rsta m\u00e5nad.<\/p>\n","protected":false},"excerpt":{"rendered":"
