La bar squall Yayiqhushumbe kakhulu yaza yabetha usingasiqithi ngoDisemba ka-2021. Yayisisiqhushumbisi esinamandla esathi sabangela umonakalo omkhulu ngexesha lokugqibela lebhulorho kaDisemba. Ngenxa yamathandabuzo okuba kwakutheni ukuze kubekho esi saqhwithi nokuba kutheni sinzulu kangaka, siza kukhangela iimpendulo.
Kweli nqaku siza kukuxelela ukuba kwakutheni ukuze uqhwithela lweBarra lwenzeke, zithini iimpawu zalo kunye nesizathu sokuba sibe sikhulu kangaka.
Ibar yeSquall
Isitshingitshane esiqhushumbayo, iBarra, esabangela iinduli zekhephu, sabangela umonakalo wokwenyani kwezinye iindawo zalosingasiqithi. Ngapha koko, i-DGT kuye kwafuneka icele abaqhubi ukuba bagoduke kwangethuba kuba kusenokwenzeka ukuba kwakuza kubakho ikhephu kumantla elizwe. INational Meteorological Service (AEMET) ilumkise ngeemvula ezininzi, umoya onamandla, ingqele kunye nekhephu elinamandla emantla, kunye Ikhephu bekulindeleke ukuba lehle liye kuma-500 m ngexesha lokugqibela kwimpelaveki ende kaDisemba.
Ngokutsho kwesithethi se-AEMET, uRubén del Campo, i-front front ebandayo yaqala ukuhamba ngaphesheya kwe-peninsula ukusuka kumntla-ntshona ukuya kumzantsi-mpuma, ehambelana nesiqhwithi esinzulu kakhulu esibizwa ngokuba yi-Barra, eyayiqhuba inkqubo ye-cyclonic eqhumayo kunye neziko layo.
ESpain, nangona kunjalo, iimpembelelo azizange zibe yingozi kangako, kuba zazibangela ukuba kugqitywe imida kwaye zenze izaqhwithi ezomeleleyo zolwandle kwiBay of Biscay, ngamaza afikelela kubude obuziimitha ezi-6 ukuya kwezisi-8.
Isiqhwithi saseBarra sasinemvula eninzi kwaye rhoqo eGalicia, iBay of Biscay kunye nePyrenees, eya kuthi iphinde ifikelele kwi-Iberian kunye ne-Central system kunye nezinye iindawo zaseMntla-ntshona, ngelixa eMzantsi isibhakabhaka esinamafu kancinane sinamandla ngaphezu kweyesithathu kwaye iMeditera. Ikhephu eligqunyiweyo laliphezulu ekuqaleni, emva koko lehla laya kutsho kwi-1.000 ukuya kwi-1.200 leemitha imini yonke, kwaye yada yehla yaya kutsho kwiimitha ezingama-700 kwiiNtaba zeCantabrian kwiiyure ezimbalwa ezidlulileyo.
Izinto ze-squall yaseBarra
Ngokutsho kweDel Campo, enye into ekufuneka ithathelwe ingqalelo ngumoya, owazisa imimoya eqinile elunxwemeni nasezintabeni, ngakumbi kwisiqingatha esisenyakatho. Imimoya ebandayo yasemntla-ntshona, eyabangela ukuba amaqondo obushushu ehle kakhulu, ngakumbi kummandla osemantla kakhulu, nto leyo eyaqhubeka ine imvula eninzi, kodwa kwakukho isixa esikhulu sePyrenees, iiNtaba zeCantabrian kunye nekhephu embindini nakwi-Iberian Peninsula.
Ngaloo ndlela, ezi nkqubo zeentaba zazinokufumana ngaphezu kwe-10 ukuya kwi-15 yeesentimitha zekhephu kwiiyure nje ezingama-24, kwaye ikhephu laliphantsi, malunga nama-500 ukuya kuma-700 eemitha kumantla akude nama-600 ukuya kuma-800 eemitha kuwo wonke umntla nasemantla.. Iindawo ezisembindini wepeninsula nazo zinekhephu, nangona zibuthathaka, kwiindawo ezikwanti zethafa kunye nemigxobhozo kwimimandla esembindini.
Ngenxa yesi sizathu, u-del Campo wabuza bonke abemi abashiya iBridge ukuba "balumke kakhulu" ngenxa yokuhamba phakathi kwesiqingatha esisemantla kunye nommandla ophakathi.
NgoLwesithathu nangoLwesine wesaqhwithi
Xa kuthelekiswa noLwesithathu, imvula ayizange inetha kwamanye amathafa amabini nakumbindi weentaba kulosingasiqithi. Kwakukho neeshawa kwiiBalearic Islands. Ngaloo mini kwafuneka sinikele ingqalelo emoyeni kwakhona, ngamaxesha athile imimoya enamandla ngaphezu kwe-80 km / h kuLwandle lwaseCantabrian, kwi-peninsula esempuma kunye neZiqithi zaseBalearic. Izaqhwithi elwandle zaqhubeka zidlala indima ebalulekileyo. ngamaza ukuya kuthi ga kwi-8 yeemitha kwiBay of Biscay kunye neemitha ezi-4 kwiMeditera.
I-Galicia, uluntu lwaseCantabrian kunye nePyrenees luya kuqhubeka nokufumana imvula enkulu ngoLwesine nangoLwesihlanu, kodwa amaqondo okushisa afudumele aya kubona i-snowpacks inyuka kakhulu, ihlala idlula i-1.500 yeemitha. Ngoko ke, kwakukho ukunyibilika kwekhephu ngezo ntsuku, ukwanda okukhulu kokuhamba komlambo kule mimandla, kwaye imihlaba kule mimandla yayimanzi ngenxa yemvula enkulu kunye nekhephu malunga neeveki ezimbini.
Ngapha koko, kwiidolophu zase-Asturias, eCantabria, kwiLizwe laseBasque nakumantla eNavarra, ngaphezulu kwe-10 l/m² eqokelelwe kwiintsuku ezili-300 ezidlulileyo, ibalaselisa i-Urkiola reserve eVizcaya, eqokelele i-10 L / m378 ngosuku. Ezi zixa zemvula zisuka kuMntla oMde ziqheleke ngaphezu kwesiqhelo kathathu kwesi sithuba seentsuku ezili-10 ezidlulileyo.
Imvula ngoLwesine nangoLwesihlanu isasazeka buthathaka ukuya enyakatho kunye neziko nakwezinye iindawo zenkqubo yePenibético, ngelixa eMeditera kwakukho iimvula ezikhanyayo kwiiBalearic Islands. NgoLwesine amaqondo obushushu anyukile kwezi ndawo, kunye neemeko ezipholileyo zexesha lonyaka, kunye neqabaka encinci kunye namaqondo obushushu amaqondo obushushu emini angaphezu kwama-20ºC kunxweme lweMeditera nasecaleni komlambo iGuadalquivir.
Kwakutheni ukuze kubekho isaqhwithi saseBarra?
Isitshingitshane seBarra senziwe ngenxa yobunzulu benkqubo yokuvelisa iinkanyamba eziqhumayo. Ngokukodwa, izaqhwithi ezinje ngeBarra ziba namandla ngokukhawuleza xa kukho unxibelelwano olusebenzayo phakathi kwezi zimbini zangaphambili:
- Izandulela zomyalelo ophezulu osebenzayo kakhulu yenziwe ziijethi zepolar groove ezichazwe kakuhle.
- Ukudakumba komphezulu okanye isandulela soxinzelelo oluphantsi.
Ngenxa yesi siganeko, okwenzekayo kukuba uqhwithela lweBarra lwenzeke "Ukuqina okungaqhelekanga", kunye nesantya esikufutshane ne-50 hPa kwiiyure ezingama-24. Oku kwaziwa ngokuba "yibhombu yemozulu," isiphumo sokudakumba okunzulu okanye isitshingitshane ngexesha elifutshane kakhulu.
Ngenxa yokutshintsha kwemozulu, sibona ipateni yokwandisa ukuphindaphindeka kunye nokuqina kwezona nkqwithelo zinamandla. Ngamanye amazwi, ngexesha lasekwindla, apho kudla ngokubakho ukungazinzi ngakumbi kwe-atmospheric, ezi ziqhwithi zinokwenzeka kakhulu. Izihlwele zomoya zihamba kunye nokuguqulwa koxinzelelo olunyukayo kunye nokwehla ngokukhawuleza ngenxa yokuguqulwa kwamaqondo obushushu behlabathi.
Ngokutshintsha ngokupheleleyo yonke imeko ye-avareji yobushushu behlabathi ngenxa yokuveliswa kweegesi zegreenhouse kwi ukugqithisa kubangela utshintsho kwiipateni zokuvela kwesiphango.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nesiqhwithi saseBarra kunye neempawu zayo.
