Nyob rau hauv Arctic, cov paj ntoo loj hlob nyob rau saum npoo ntawm ib txheej nyias nyias ntawm dej khov. Qhov no yog li cas cov kws tshawb fawb npe hu ua poov npe hu ua cov ntawv ci, qhov siab uas tsis ntau dua ob peb centimeters. Muaj ntau ntau qhov kev tshwm sim ntawm kev rov tshwm sim ntawm ib qho ntawm qhov tshwm sim zoo nkauj tshaj plaws hauv Arctic.
Raws li ib qho ntawm lawv, muaju yog cov hws ntawm huab cua supersaturated nrog ya raws. Cov neeg txhawb nqa ntawm lwm txoj hauv kev paub tseeb tias thaum dej ntsev nce los ntawm dej khov pores, "cov nroj tsuag txuj ci tseem ceeb" tshwm sim. Muaj lwm qhov ntxiv: kev hloov pauv thoob ntiaj teb hauv tus qauv ntawm Arctic dej los ua ib qho zoo tshaj plaws pom tshwm sim hauv lub neej.
Ua rau muaj qhov tshwm sim
Txhua tus kws tshawb fawb pom zoo tsuas yog ib yam: muaju "loj hlob" tsuas yog ntawm cov dej khov tshiab thiab tshiab. Cov dej khov ua paj tau raug tshawb fawb los ntawm Robert Style thiab Grey Worster ntawm Lub Koom Haum rau Theoretical Geophysics, University of Cambridge. Qhov txiaj ntsig yog qhov xaus hais tias nws tsis koom nrog kev tsim ntawm ya raws thiab ntsev.
Tom qab ntau cov kev suav thiab lawv cov tshev hauv chav kuaj, nws muab tawm tias cov qauv xav tau tsis tsuas yog cov dej khov txheej, tab sis tseem muaj qhov kub sib txawv ntawm nws thiab huab cua. Nws qhov tsawg kawg nkaus yog 20 C. Kev ua siab loj, qhov tshwm sim tuaj yeem pom nyob rau hauv lub cev dej tshiab.
Kev hloov ntawm cov kua los ntawm ib qho ncaj qha mus rau daim ntawv gaseous tuaj yeem tshwm sim tsis yog hauv Arctic. Nyob rau hauv huab cua txias, yog tias qhov kub ntawm cov dej khov dej yog xoom, sab nraud qis dua -20 C, txheej txheej oversaturated nrog cov qauv noo noo.
Kev Tshawb Fawb
Thaum nws nkag mus rau qhov kev sib cuag nrog huab cua txias, qhov txias txias kom pib nrog rov ua cov hws ntawm thaj chaw. Raws li qhov tshwm sim, muaju pom ntawm dej khov. Tom qab qee lub sijhawm, ntsev dauv los khom ntawm lawv, yog li cov dej noo hauv cov zauv uas tsim tau yog noo nrog ntsev ntau dua li hauv hiav txwv.
Xib fwb Worster hais txog qhov tsis yooj yim ntawm cov paj nab kuab. Nws tseem yog ib qho tseem ceeb kom them sai sai rau qhov tseeb tias nrog qhov nce ntawm cov dej khov tuab, nws qhov kub saum npoo muaj huab cua. Raws li qhov tshwm sim, tsis muaj dab tsi tseem tshuav ntawm cov muaju.
Lub luag haujlwm tseem ceeb yog ua si los ntawm qhov tseeb tias tuab ntawm txheej txheej oversaturated nrog noo noo tsis yog tas mus li, vim nws nyob ntawm ntau yam ntawm ntau yam.
Tswvyim hais ua dabneeg thiab qhov tiag
Raws li txoj kev tshawb fawb los ntawm cov kws tshawb fawb British, nws muaj peev xwm twv seb qhov tshwm sim zoo dua ua ntej. Nws yog qhov yuav tsum tau tswj hwm tus txheej txheem kawm ntawv. Qhov no yog qhov tseem ceeb tshaj plaws hauv kev xav ntawm cov kws tshawb nrhiav, txij li cov ntaub ntawv tau txais paub meej tias cov muaju tsis nyab xeeb zoo li lawv zoo li.
Cov dej khov paj tso tawm ntau cov lus teb bromine rau hauv qhov chaw. Qhov no cuam tshuam tsis zoo rau lub xeev ntawm ozone txheej. Tab sis cov kws tshawb fawb tseem tseem tsis tuaj yeem txiav txim siab txog qib muaj kev phom sij nrog qhov raug siab.
Tam sim no, Arctic tau nce tas li ntawm cov dej khov txhua xyoo. Txij li qhov tsim ntawm crystalline ornaments yog ua tau tsuas yog ntawm cov dej khov thiab cov tub ntxhais hluas, qhov kev xav ntawm qhov phom sij xav tau qhov yuav tsum tau kuaj xyuas kom paub meej lossis rov ua lub siab xav.
