"Timaha barafka", oo sidoo kale loo yaqaan "dhogor baraf" ama "garka barafka" (barafka timaha, dhogorta barafka ama gadhka dhaxan) waa nooc ka mid ah baraf ka samaysan alwaax dhintay oo u eg timo xariirta fiican.
Dhacdadan ayaa inta badan lagu arkay Waqooyiga Hemisphere, inta u dhaxaysa 45aad iyo 50aad ee isbarbardhigga, ee kaymaha googo'an. Si kastaba ha ahaatee, xitaa ka sarreeya barbaraha 60-aad, barafkan quruxda badan ee cajiibka ah ayaa laga heli karaa ku dhawaad wakhti kasta, haddii kaliya ay jirto kayn ku habboon iyo cimilo "sax ah" (qoraaga qoraalka).
"Timaha barafka" waxay ku samaysan yihiin alwaax qoyan oo qudhuntay (looxyo dhintay iyo laamo cabbirro kala duwan leh) heerkulka wax yar ka hooseeya eber iyo qoyaan aad u sarreeya. Waxay ku koraan alwaax, maaha dusha sare ee jilif, waxayna ka soo muuqan karaan meel isku mid ah dhowr sano oo isku xigta. Timo kastaa wuxuu leeyahay dhexroor qiyaastii 0.02 mm waxayna kori karaan ilaa 20 sentimitir (inkasta oo muunado suubban ay aad u badan yihiin, ilaa 5 cm dheer). Timaha ayaa ah kuwo aad u jilicsan, laakiin, si kastaba ha ahaatee, waxay ku duuduubi karaan "mawjadaha" iyo "curls". Waxay awoodaan inay qaabkooda sii wadaan saacado badan, iyo xitaa maalmo. Tani waxay soo jeedinaysaa in shay uu ka hortagayo barafka inuu dib u soo celiyo - habka loo beddelo kirismaska barafka yaryar ee waaweyn, kaas oo caadi ahaan aad u firfircoon marka heerkulka wax yar ka hooseeya eber.
Dhacdadan la yaabka leh waxaa markii ugu horreysay ku sifeeyay 1918-kii geophysicist Jarmal iyo saadaasha hawada, abuuraha aragtida qulqulka qaaradda Alfred Wegener. Waxa uu soo jeediyay in nooc ka mid ah fungus laga yaabo inay sabab u tahay. Sannadkii 2015, saynisyahano Jarmal iyo Swiss ah ayaa caddeeyey in fangaskani uu yahay Exidiopsis effusa, xubin ka tirsan qoyska Auriculariaeae. Sida saxda ah sida fangasku uu barafku u keeno baraf sidan oo kale ah maaha mid gebi ahaanba cad, laakiin waxaa loo malaynayaa inay soo saarto nooc ka mid ah dib-u-kicinta recrystallisation, oo la mid ah ficilkeeda si ay uga hortagto borotiinnada. Si kastaba ha ahaatee, fangaskani wuxuu ku jiray dhammaan shaybaarrada alwaax ah "timaha barafka" koray, iyo kala badh kiisaska waxay ahayd noocyada kaliya ee la helay, iyo xakamaynta fungicides ama soo-gaadhista heerkulka sare ayaa horseeday xaqiiqda ah " timaha baraf" mar dambe ma soo muuqan.
Boqoshaada lafteedu aad bay u caddahay, haddaysan ahaan lahayn timaha barafka ee yaabka leh, dheg uma ayteen. Si kastaba ha ahaatee, xilliga diiran lama dareemo.
