Gamta vis labiau nyksta d\u0117l visuotinio at\u0161ilimo ir klimato poky\u010di\u0173. Spar\u010diai tirpstant a\u0161igali\u0173 ledui, nyksta biologin\u0117 \u012fvairov\u0117 ir kyla susir\u016bpinimas d\u0117l j\u016bros lygio.<\/p>\n\n\n\n

J\u016bros ledo storis yra barometras, padedantis suprasti Arkties regiono b\u016bkl\u0119. Kuo storesnis ledas, tuo didesn\u0117 jo \u0161ilumin\u0117 izoliacija, neleid\u017eianti vandenyno pavir\u0161iaus temperat\u016brai pakilti \u017eiem\u0105 ir apsauganti nuo kar\u0161\u010dio vasar\u0105.<\/p>\n\n\n\n

Taip pat ma\u017eiau tik\u0117tina, kad vasar\u0105 Arktyje tirpstant\u012f led\u0105 i\u0161laikys plonesnis ledas.<\/p>\n\n\n\n

Tod\u0117l mokslininkai \u012fvertino naujai sukurtos kompiuterin\u0117s programos, skirtos kasmetiniam sniego gylio skirtumui \u012fvertinti, rezultatus ir nustat\u0117 j\u016bros ledo plon\u0117jimas<\/strong> paspart\u0117jo daug labiau, nei tik\u0117tasi.<\/p>\n\n\n\n

Tyrimo tikslas ir u\u017edaviniai<\/strong><\/h2>\n\n\n\n

Kadangi j\u016bros ledo danga palengvina oro ir vandens mainus bei \u0161ilumos perdavim\u0105 tarp vandenyn\u0173 ir atmosferos, ji turi \u012ftakos regionin\u0117ms ekosistemoms, pusiaujo v\u0117j\u0173 pob\u016bd\u017eiui ir pasauliniam klimatui.<\/p>\n\n\n\n

D\u0117l storesnio j\u016bros ledo padid\u0117ja \u0161ilumin\u0117 izoliacija, tod\u0117l \u017eiem\u0105 temperat\u016bra i\u0161lieka \u017eemesn\u0117.<\/p>\n\n\n\n

Nuo j\u016bros ledo storio sniego kaupimosi metu priklauso ir j\u016bros ledo gylis po vandens pavir\u0161iumi, kuris labai prisideda prie termodinaminio j\u016bros ledo augimo. Tod\u0117l j\u016bros ledo storis yra svarbus regiono b\u016bkl\u0117s rodiklis. <\/p>\n\n\n\n

Tyr\u0117jai naudojo CryoSat-2<\/a> palydovinis radaras, skirtas j\u016bros ledo storiui matuoti \u0161iame tyrime.<\/p>\n\n\n\n

Buvo siekiama palyginti senojo modelio duomenis su naujuoju modeliu, kuris apima klimato kait\u0105.<\/p>\n\n\n\n

Ledo auk\u0161t\u012f vir\u0161 vandens galima nustatyti nustatant laik\u0105, per kiek laiko atsispindi radaro bangos, ir taip \u012fvertinti jo stor\u012f.<\/p>\n\n\n\n

Naudojant Lagran\u017eo sniego kaupimosi model\u012f \"SnowModel-LG\" buvo prognozuojamas bendras sniego storis ir tankis \u012fvairiose Arkties vandenyno vietose, atsi\u017evelgiant \u012f v\u0117jo, temperat\u016bros, krituli\u0173 ir ledo jud\u0117jimo analiz\u0119.<\/p>\n\n\n\n

Po to sniego modelio rezultatai buvo derinami su palydovinio radaro duomenimis, siekiant \u012fvertinti, kaip spar\u010diai ma\u017e\u0117ja j\u016bros ledo storis Arktyje ir kaip jis gali kisti laikui b\u0117gant.<\/p>\n\n\n\n

J\u016bros ledo storio kintamumas kra\u0161tin\u0117se j\u016brose buvo padidintas 50 proc. faktoriumi, \u012ftraukiant sniego dangos kintamum\u0105.<\/p>\n\n\n\n

J\u0173 tyrimo duomenimis, sniego dangos svyravimai lemia vis didesn\u0119 j\u016bros ledo storio kintamumo dal\u012f - nuo ma\u017edaug 20% iki daugiau nei 70% sezoniniu laikotarpiu.<\/p>\n\n\n\n

Sniego modelio ir LG duomenimis pagr\u012fstos tendencijos taip pat buvo pasteb\u0117tos j\u016bros ledo storio statistikoje - jos sustiprino ledo storio ma\u017e\u0117jim\u0105 tose vietov\u0117se, kur jo jau buvo, ir gerokai suma\u017e\u0117jo tose vietov\u0117se, kur jo dar nebuvo.<\/p>\n\n\n\n

D\u0117l did\u0117jan\u010dio anglies p\u0117dsako ma\u017e\u0117ja ledo dangos, nes \u017emon\u0117s labai padidino veiklos, daran\u010dios poveik\u012f aplinkai, skai\u010di\u0173. D\u0117l tirpstan\u010dio ledo taip pat prarado gyvenam\u0105sias vietas kelios poliarini\u0173 region\u0173 gyv\u016bn\u0173 r\u016b\u0161ys. J\u016br\u0173 ledo storio vertinimui bus taikomas holistinis po\u017ei\u016bris, pasitelkiant j\u0173 integruot\u0105 model\u012f, kuris u\u017epildo pasenusi\u0173 analiz\u0117s sistem\u0173 spragas ir apima tokius veiksnius kaip klimato kaita.<\/p>\n\n\n\n

J\u0173 atliktas tyrimas yra svarbus etapas, kuris neabejotinai gali prisid\u0117ti prie platesnio vaizdo, siekiant i\u0161siai\u0161kinti tikr\u0105j\u0105 prie\u017east\u012f.<\/p>\n\n\n\n
