Ukushintsha kwesimo sezulu kuthinta kanjani inani nokusatshalaliswa kwemvula ngaphansi kombhede wehlathi? Futhi iyiphi indima edlalwa izihlahla eminyakeni eyomile nemanzi? Ithimba labacwaningi abavela eNyuvesi yaseGöttingen liphenye le mibuzo, lisebenzisa izinsiza zokulinganisa eziningi ukuze lihlole ihlathi le-beech esifundeni sase-Göttingen esikhathini esiyiminyaka eyisikhombisa. Phakathi kokunye abacwaningi bakwazile ukukhombisa ukuthi isilinganiso semvula efika phansi sehla ngamaphesenti angu-5,75 unyaka ngamunye.
Amamodeli okushintsha kwesimo sezulu abonisa ukuthi amaphethini emvula eYurophu aya ngokuya eshintshashintsha, eshintshashintsha kakhulu, futhi ebangela ukusabela kochungechunge lwemiphumela ezindaweni zemvelo . Kuze kube manje, ulwazi mayelana nezinguquko zangempela emvuleni ngaphakathi kwezindawo zemvelo zamahlathi beluyingxenyana. Ngakho-ke, ngo-2017, abacwaningi baseGöttingen bafake izinzwa zemvula ezingama-30 namadivayisi okuqoqa amaqabunga ehlathini eliseduze ne-Ebergötzen. Ngaphezu kwalokho, izihlahla zalinganiswa ngokuphindaphindiwe kusetshenziswa izikena ze-laser. Lokhu kwavumela abacwaningi ukuthi babhale njalo izehlakalo zemvula, izikhathi zokomisa, kanye nesilinganiso samanzi angena emphemeni iminyaka eyisikhombisa. Ngakho-ke bakwazi ukufunda iminyaka eyomile nemanzi ngendlela engavamile, njengo-2018 no-2021, ngokuningiliziwe. "Sekukonke, idatha ikhombisa ukuthi inani nobude bezehlakalo zemvula ngayinye buyehla, kuyilapho ukuqina kuyanda," kuchaza umbhali oholayo uDkt. Simon Drollinger ovela eMnyangweni we-Bioclimatology. "Ngenxa yalokho, isilinganiso samanzi afinyelela phansi kwehlathi siyehla, okuholela ekushintsheni okukhulu kwendawo emazingeni omswakama."
"Lokhu kancane kancane kuholela ekunqanyulweni kokunyakaza kwamanzi endaweni yemvelo yehlathi," kuchaza omunye umbhali uDkt. Michael Dietze ovela eMnyangweni Wezendawo Yendawo. "Nakuba imiphumela yalokhu kulungiswa kabusha kwezindlela zamanzi ehlathini ayikathinti izihlahla, njengoba amasampula avela kubaqoqi bamaqabunga ebonisa, silindele ukukhuphuka kwe-heterogeneity, okungukuthi umehluko ekusabalaliseni kwendawo yomswakama womhlabathi kanye nomsebenzi ohambisana nawo wama-microorganisms alulaza izinto eziphilayo emhlabathini," kunezela uProf. Ebergötzen. Esinyathelweni esilandelayo, abacwaningi bafuna ukuhlola amasampula amanzi enhlabathi aqoqwe ngokuhamba kwesikhathi kanye namanani alinganisiwe omswakama wenhlabathi kanye nezinga lokushisa. Ukwengeza, izinzwa ze-geophysical zizosetshenziselwa ukuqapha ukuguquguquka kwamanzi ekujuleni okukhulu.
