"Ice plaub hau", tseem hu ua "ice wool" los yog "tej hwj txwv" (cov plaub hau dej khov, ice wool los yog frosty hwj txwv) yog ib hom dej khov uas tsim rau ntawm ntoo tuag thiab zoo li cov plaub hau zoo.
Qhov tshwm sim no tau pom feem ntau nyob rau sab qaum teb Hemisphere, nruab nrab ntawm 45th thiab 50th parallels, hauv hav zoov deciduous. Txawm li cas los xij, txawm tias saum toj ntawm 60 qhov sib npaug, qhov dej khov zoo nkauj no tuaj yeem pom yuav luag txhua qhov tig, yog tias tsuas yog muaj hav zoov tsim nyog thiab "tsim" huab cua (tus sau ntawv sau).
"Cov plaub hau dej khov" yog tsim rau ntawm cov ntoo ntub dej (cov ntoo tuag thiab cov ceg ntoo ntawm ntau qhov ntau thiab tsawg) ntawm qhov kub me ntsis hauv qab xoom thiab cov av noo txaus. Lawv loj hlob ntawm ntoo, tsis nyob rau saum npoo ntawm cov tawv ntoo, thiab tuaj yeem tshwm nyob rau hauv tib qhov chaw rau ob peb xyoos ua ke. Txhua tus tib neeg cov plaub hau muaj txoj kab uas hla ntawm 0.02 hli thiab tuaj yeem loj hlob mus txog 20 cm ntev (txawm tias cov qauv me me muaj ntau dua, txog li 5 cm ntev). Cov plaub hau yog yooj yim heev, tab sis, txawm li cas los xij, lawv tuaj yeem curl rau hauv "nthwv dej" thiab "curls". Lawv muaj peev xwm tuav tau lawv cov duab rau ntau teev, thiab txawm hnub. Qhov no qhia tau hais tias ib yam dab tsi tiv thaiv cov dej khov los ntawm recrystallizing - cov txheej txheem ntawm tig cov dej khov me me rau hauv cov loj loj, uas ib txwm muaj zog heev ntawm qhov kub qis dua xoom.
Qhov no amazing tshwm sim yog thawj zaug piav nyob rau hauv 1918 los ntawm German geophysicist thiab meteorologist, creator ntawm txoj kev xav ntawm continental drift Alfred Wegener. Nws tau hais tias qee yam kab mob fungus yuav yog qhov ua rau. Xyoo 2015, German thiab Swiss cov kws tshawb fawb tau ua pov thawj tias cov kab mob no yog Exidiopsis effusa, ib tus tswv cuab ntawm tsev neeg Auriculariaceae. Raws nraim li cas cov fungus ua rau cov dej khov crystallize nyob rau hauv txoj kev no yog tsis meej kiag li, tab sis nws yog assumed tias nws tsim ib co hom ntawm recrystallization inhibitor, zoo ib yam li nyob rau hauv nws cov kev ua rau antifreeze proteins. Txawm li cas los xij, cov kab mob no tau tshwm sim hauv txhua qhov piv txwv ntawm cov ntoo uas "cov plaub hau dej khov" loj hlob, thiab hauv ib nrab ntawm cov xwm txheej nws tsuas yog pom, thiab nws cov tshuaj tua kab mob los yog raug kub hnyiab tau ua rau lub fact tias " cov plaub hau dej khov” tsis tshwm sim lawm.
Cov nceb nws tus kheej yog qhov yooj yim, thiab yog tias nws tsis yog rau cov plaub hau txawv txawv ntawm cov dej khov, lawv yuav tsis tau them nyiaj rau nws. Txawm li cas los xij, nyob rau lub caij sov nws tsis pom.
