Abacwaningi baseSpain bathi isichotho esikhulu sibangelwa ukushintsha kwesimo sezulu

amatshe esichotho amakhulu

Ekutholakaleni okudabukisayo, ososayensi abavela emanyuvesi amaningana eSpain baxhumanise isiphepho esikhulu sesichotho esenzeka esifundazweni saseGirona ngo-Agasti 2022 kanye nomthelela wokuguquka kwesimo sezulu. Futhi kuya ngokuya kucatshangwa ukuthi ukwanda kwesichotho kubangelwa ukushintsha kwesimo sezulu.

Kulesi sihloko sizokutshela ukuthi kungani Abacwaningi baseSpain bathi isichotho esikhulu sibangelwa ukushintsha kwesimo sezulu.

Isichotho esingokomlando

amabhola amakhulu esichotho

Abacwaningi abavela e-Complutense University of Madrid (UCM), i-University of Valladolid (UVA) kanye ne-Pablo de Olavide University of Seville (UPO) banqume ukuthi ukuhlangana kwegagasi lokushisa olwandle kanye nokushintsha kwesimo sezulu okubangelwa abantu kudlale indima ebalulekile indima ekubukeni kwesichotho esingakaze sibonwe, esinamatshe esichotho afinyelela ku-12 cm ububanzi, esifundazweni saseGirona ngo-Agasti 30, 2022.

I-Complutense University ibike namuhla lokho Abacwaningi baye basungula, ngokokuqala ngqa, ubudlelwano obuqondile phakathi kokushintsha kwesimo sezulu kanye nalolu hlobo oluthile lwezigigaba ngokusetshenziswa kwezibalo zezinombolo.

Ochwepheshe baqokomisa ngokuqondile iqiniso lokuthi ukwakheka kwe-supercell, isiphepho esikhulu nesibhubhisayo esijikelezayo, kwaqhutshwa izinga elingenakuqhathaniswa lamandla okuguqula. Lawa mandla okusebenza asebenza njengesisusa sokwakhiwa kwala maseli amakhulu kakhulu emkhathini, okuholela esiphephweni esinamandla kakhulu esikhuthaza ukuthuthukiswa kwesichotho esikhulu. Isichotho salolu bukhulu sidala umonakalo omkhulu ngokomzimba nangokwezinto ezibonakalayo.

Ngemuva kwesiphepho, esithinte kakhulu isifunda sase-Baix Empordà, Ukucekelwa phansi okukhulu kwezinto ezibonakalayo kwabonwa ezimotweni, ophahleni nasezinsimini zezitshalo, ukulimala okuningi futhi, ngeshwa, ukufa kokuqala. eqoshwe eYurophu ngenxa yesichotho eminyakeni engamashumi amabili edlule.

Kungani isichotho siba njalo?

amabhola eqhwa

U-Mariano Sastre, umcwaningi ku-Department of Earth Physics and Astrophysics e-UCM, ugqamise ukubaluleka kocwaningo ukuze kuthuthukiswe ukuqonda kwethu ukuvela kwesichotho esibi kakhulu. Iphinde igcizelele ukuphuthuma kokuqaliswa kwamasu okulwa nokuguquguquka kwesimo sezulu kanye nokudambisa imiphumela yako eyingozi, ikakhulukazi emiphakathini esengozini yokungenwa yimithelela yako.

Abacwaningi benze ucwaningo, okutholwe kulo kwashicilelwa ku-Geophysical Research Letters, ngokwenza amasethi amabili ahlukene okulingiswa kwezinombolo. Isethi yokuqala iphindaphinde izimo zamanje, kuyilapho eyesibili idale kabusha izinga langaphambi kwezimboni, elimele inkomba yezinga lokushisa emhlabeni wonke ngaphambi kweNguquko Yezimboni.

Lesi sikhathi saziwa njengesiqalo sokukhululwa njalo nokuqhubekayo kwamagesi abamba ukushisa anthropogenic. Kwakuphakathi nalolu cwaningo lapho ukwakheka kwamatshe esichotho amakhulu kwenziwa lula ukushisa olwandle.

Abacwaningi baqaphele ukuthi leli zinga elithile lisebenza njengophawu lokukala umthelela walokhu kukhishelwa kanye nemiphumela yokufudumala kwembulunga yonke. Ngaphezu kwalokho, bagcizelele ukuthi, uma kuqhathaniswa nezimo zangaphambi kwemboni, imodeli ihlale ikhiqiza osayizi besichotho abancane kakhulu kunalabo ababonwa ngokoqobo.

Okutholakele futhi kunikeza ukuqonda ngokubaluleka kwegagasi lokushisa olwandle, isenzakalo lapho izinga lokushisa lolwandle noma lolwandle likhuphuka kakhulu, lapho uphromotha "convective" umoya osiza ukuthuthukiswa kwesichotho esikhulu.

U-Sastre wachaza ukuthi lapho ukulingisa kuqeda kokubili ukuphoqelelwa kwe-anthropogenic kanye nomthelela wegagasi lokushisa olwandle, kwaba nokwehla okuphawulekayo kwezimo eziguquguqukayo ezivumela ukuthuthukiswa kwesichotho esikhulu. Lolu lwazi lubalulekile ekusungulweni kwephrothokholi eyisixwayiso engazisa ngempumelelo isibalo sabantu ngezichotho ezingaba khona.

Ucwaningo olwengeziwe luyadingeka ukuze kuzuzwe ukuqonda okujulile kokuxhumana okuyinkimbinkimbi phakathi kwezimo zezulu ezimbi kakhulu kanye nomthelela wokuguquka kwesimo sezulu okubangelwa abantu.

Izinjongo zophenyo

isichotho umonakalo

Enye yezinhloso ezilandelayo zabacwaningi ukusiza ekwakhiweni kohlelo lwesexwayiso izinsizakalo zesimo sezulu ezingalusebenzisa ukwazisa umphakathi ngokushesha uma kwenzeka isigameko esifanayo esikhathini esizayo. Isichotho esibhubhisayo esenzeka ngo-Agasti 30, 2022 kumasipala wase-La Bisbal d'Empordà, e-Girona, sadabukisa kakhulu i-Spain. Lesi sigameko esiyinhlekelele sabangela ukufa kabuhlungu kuka ingane enezinyanga ezingu-20 yalimaza abantu abangu-67, kuyilapho amabhola eqhwa afinyelela kumasentimitha angu-12 ububanzi enile.

Izithombe eziphazamisayo ezithwetshulwe izakhamuzi zibonise lawa matshe amakhulu ecwila emachibini, afana neshawa ye-meteor futhi edala isimo se-apocalyptic. Manje sekutholakele ukuthi imbangela eyinhloko yale nhlekelele kwakuwukwanda kwezinga lokushisa lomoya okubangelwa imisebenzi yabantu.

Encwadini esanda kushicilelwa kujenali i-Geophysical Research Letters, uCarlos Calvo Sancho kanye nethimba lakhe bethula abakutholile ocwaningweni lwabo, olusebenzise ukulingiswa kwezinombolo ukucacisa izici ezinomthelela ekuqineni kwesiphepho ngendlela engakaze ibonwe. Imiphumela ibonisa ukuthi inhlanganisela yamandla amaningi asemkhathini kanye negagasi lokushisa olwandle phakathi nalelo hlobo elithile eMedithera kungabonisa ubukhulu besiphepho.

Kubalulekile ukuqaphela ukuthi ngaphandle kwethonya lokufudumala okubangelwa umuntu, ukwakheka kwesichotho esikhulu kangaka kwakungeke kwenzeke. Lesi sichotho singesikhulu kunazo zonke ezake zaqoshwa ezweni lethu futhi saholela kabuhlungu ekulahlekelweni kwempilo, kube ukufa kokuqala okudalwe yisichotho kule minyaka engamashumi amabili edlule.

Inani lesichotho esikhulu likhule kakhulu. NgokukaCalvo Sancho, umcwaningi we-predoctoral e-University of Valladolid (UVa), lapho ukulingisa kwenziwa ngezinga lokushisa lolwandle elivamile ngaleso sikhathi esithile sonyaka, i-supercell eyakhiwe phezu kwe-Girona ihlala injalo, kodwa akukho sisindo esikhulu ngokungavamile esakhiwayo. . isichotho.

Eminyakeni emithathu edlule, kusukela ngo-2021 kuya ku-2023, siye sabona imvamisa efanayo yezenzakalo zesichotho ezinkulu noma ezinkulu kakhulu njengaso sonke isikhathi kusukela ngo-2011 kuya ku-2019. Lo mkhuba oshaqisayo uye waholela ochwepheshe ezingeni laseYurophu ukuthi bahlonze isichotho. njenge usongo olunamandla kakhulu oluhambisana nesimo sezulu esibi esizayo. Umthelela oqondile onawo kubantu, ezolimo kanye nempahla kwenza kube yinto ekhathaza kakhulu.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngokuthi kungani abacwaningi baseSpain bethi isichotho esikhulu sihlobene nokushintsha kwesimo sezulu.
