Qiyaasta glacier ee NVE ee 2023 waxay muujineysaa in 33 ka mid ah 36 barafka hore ee la cabbiray ay dhalaaleen, iyo dhammaan 10-ka barafka ee cabbiraadda dheelitirka ballaaran ee la qaaday ay ku jireen khasaare ballaaran.
Hoos u dhaca ugu weyn sanadkan waxaa laga diiwaan geliyay Bondhusbrea oo ku taal galbeedka Folgefonna (-92 m), Bøverbrean ee Jotunheimen (-82 m) iyo Engabreen ee Nordland (-78 m). Sannadkan, 36 baraf ah ayaa dhalaalay celcelis ahaan 27 mitir.
Koonfurta Jiilaalkan Norway waxa ka jiray farqi weyn tirada barafka ee barafka. Barafka barafka badan ee galbeedka Norway way ka yaraatay baraf ka badan sidii caadiga ahayd, halka barafka bari ka xiga uu helay baraf ka badan sidii caadiga ahayd. Laakin dhalaalka glacial aad buu u sarreeyaa xagaaga oo dhan dhammaan barafka barafka ee koonfurta Norway. Natiijada 2023 sidaas darteed waxay ahayd mid aan la dhayalsan karin dhammaan barafka la qiyaasay, iyo malaha sidoo kale dhammaan barafka koonfurta Norway.
Waqooyiga Norway, barafyada barafku waxay heleen xadiga caadiga ah ee barafka. Si kastaba ha ahaatee, dhalaalidda glacial ayaa si fiican uga sarreeyay heerka caadiga ah xagaaga oo dhan, sidaas darteed tirada 2023 waxay u badan tahay in la dhayalsado inta badan ee barafka.
Isu-dheelitirnaanta tirada xun ee wakhti dheer
- Dhammaan barafka aan ku cabbirno dheelitirka tirada guud waxay lahaayeen miisaan taban tan iyo sannadkii 2000, ayuu yidhi khabiirka glaciologist ee NVE Hallgeir Elvehøy.
Laga soo bilaabo sanadkii 2000, barafka barafka ee Noorway aad buu hoos ugu dhacay dherer ahaan, bed ahaan iyo dhumuc ahaanba. 20kii sano ee la soo dhaafay, 28 barafka, oo si joogto ah loo cabbiray, ayaa dib u gurtay celcelis ahaan 391 mitir.
- Sababta dib-u-noqoshada hore ee barafka waa in wakhti ka dib, baraf badan iyo baraf dhalaalaan xagaaga marka loo eego dayrta jiilaalka. Waxaan leenahay dheelitirka mass ayaa xun. Tan iyo sannadkii 2000, dhumucda tobanka barafka ah ee NVE ku qiyaasto dheelitirnaanta tirada ayaa hoos u dhacay ilaa 30 mitir, ayuu yidhi Hallgeir Elvehøy.
Barafka barafka ee Noorway wuxuu leeyahay horumar la mid ah kuwa ugu badan ee barafka barafka ee adduunka intiisa kale.
