Emva kweentsuku ezininzi zobushushu kwiindawo ezininzi zelizwe, ukufika kwe inombolo ebandayo ye-42 Kuza kuphawula utshintsho olukhulu kwimozulu, kunye nomoya opholileyo kakhulu, iimvula ezinkulu kunye nomoya ovuthuzayo oza kubonakala ukusuka emantla ukuya kumzantsi-mpuma weMexico.
Nangona intwasahlobo sele iqalile, le nkqubo intsha yangaphambili iya kuhamba kunye ne ubunzima bomoya wepolar kunye nezinye izinto eziphakamileyo eziya kudala uvakalelo "lobusika obuphelileyo" ngempelaveki yokugqibela kaMatshi, ingakumbi kwiindawo ezineentaba nakwiindawo zeGulf of Mexico.
Iza kufika nini i-cold front 42 kwaye iza kuhamba njani?
Ngokwengxelo ende evela kwiiarhente zemozulu, inkqubo entsha yangaphambili ichongiwe njenge umphambili obandayo 42 Iza kuqala isondele emantla elizwe ize ekugqibeleni idlulele ngaphakathi kwilizwe laseMexico ngexesha emva kwemini/ngokuhlwa ngoLwesihlanu ekupheleni kukaMatshiIntshukumo yayo iza kuqhubeka phakathi koMgqibelo neCawa, iqhubekela phambili ukusuka emantla-mpuma ukuya empuma nakumzantsi-mpuma.
Ekuqaleni, umphambili uza kudityaniswa ne umjelo ophantsi woxinzelelo Ifumaneka phezu kweNorthern Plateau, oku kuya kukhokelela ekukhuleni kwamafu, iimvula, kunye neendudumo ezizimeleyo kumazwe asemantla nakumantla-mpuma. Njengoko inkqubo isiya kwiGulf of Mexico, ukusebenzisana nokufuma okuvela kwi- Ulwandlekazi lwePasifiki, iGulf of Mexico, kunye noLwandle lweCaribbean Iya kuqinisa imvula empuma nakumzantsi-mpuma.
Kumanqanaba aphakathi naphezulu omoya, ubukho be- umkhombe wepolar kunye nomsinga we-jet ongaphantsi kwetropiki, izinto ezimbini eziza kwenza kube lula ukufika komoya obandayo kunye nophuhliso lwamafu amaninzi, kunye neziganeko zemozulu embi kwezinye iindawo zelizwe ngempelaveki.
Le meko iza kuncediswa yipateni ye iinkanyamba eziphakathi kummandla osemazantsi-mbindini kunye nee-anticyclones ezibuthathaka emantla, imeko evula ithuba lokungena komoya ongaphezulu kwi-polar kunye nokwehla kobushushu ekuqaleni kuka-Epreli.
Ukwehla kwamaqondo obushushu kunye neqabaka kwiindawo eziphakamileyo
Isiphumo esiphambili somphezulu obandayo 42 siya kuba ukwehla okubalulekileyo kobushushuIngakumbi kwiindawo ezisemantla, emantla-mpuma, embindini, nasempuma yelizwe. Ubunzima bomoya we-polar obunxulumene nale nkqubo buza kubangela ukubanda kakhulu kusasa, kunye namaqondo obushushu angaphantsi kwe-zero kwiindawo zeentaba.
Iindawo eziphakamileyo ze Coahuila, Nuevo León, San Luis PotosÃ, Aguascalientes, Jalisco, Michoacán, Guanajuato, Querétaro, Mexico City and Oaxaca Amaqondo obushushu aya kuhluka ukusuka kwi-0 ukuya kwi-5°C kusasa, kunye indawo ebanda kakhulu kunye nomngcipheko weqabaka elincinci, ingakumbi kwiindawo zasemaphandleni nakwiintlambo eziphakamileyo.
Embindini welizwe, kuquka Valle de MexicoKulindeleke ukuba ubushushu bube sezantsi kakhulu. Isixeko saseMexico siza kuba neentsasa ezipholileyo, ezinemimoya ephakathi kunye nomoya obandayo ophantsi kunakwiintsuku ezidlulileyo, nto leyo eyahluke kakhulu kwiimini ezishushu zeentsuku ezimbalwa ezidlulileyo.
Nangona kukho ukupholisa ngokubanzi, kwiindawo ezahlukeneyo ecaleni konxweme nakwimimandla Usingasiqithi Yucatan Amaqondo obushushu aphezulu aya kuhlala ephakathi kwama-32 nama-39 ºC, aze aphakame kancinci kwiindawo ezikumntla-ntshona, apho umoya obandayo ungayi kukwazi ukuphumelela ngamandla angako.
Imvula enkulu, iimvula kunye neendudumo
I-Cold front 42 ayizukuzisa kuphela imozulu ebandayo; isiqendu se Imvula yana kwiindawo ezininzi kulo mmandlakunye nokuqokelelana okukhulu kwamanye amazwe. Ukudibana kwenkqubo yangaphambili kunye neembiza ezinoxinzelelo oluphantsi kunye nokungena komswakama ovela kwiindawo ezintathu ezinkulu zamanzi ezijikeleze iMexico kuya kunceda iimvula kunye nezivuthuvuthu kangangeentsuku ezininzi.
Phakathi koLwesithathu oludlulileyo noLwesihlanu, nangaphambi kokuba kufike umkhosi opheleleyo wemfazwe, umkhombe womoya ophantsi kuMzantsi-mpuma kunye nomsele ophezulu phezu kweGulf of Mexico uza kuqhuba amafu ophuhliso ajikelezayo. Kulindeleke iimvula ezinkulu ngeli xesha ePuebla, eVeracruz, eOaxaca naseChiapas, kunye neemvula kwamanye amazwe akumzantsi, empuma nakwiYucatan Peninsula.
Ngokufika okuqinisekileyo kwenkqubo yangaphambili, ukususela ngoLwesihlanu ukuya ngeCawa, kulindeleke oku kulandelayo Iindudumo ezisasazekileyo kunye nemvula enamandla ahlukeneyo ngaphezulu kwesiqingatha selizwe. IVeracruz, iTabasco, iOaxaca kunye neChiapas Zinokuqokelelana phakathi kwe-10 kunye ne-75 mm, ingakumbi kwiindawo ezineentaba nakwiindawo ezikufutshane neGulf.
NgeMigqibelo, imvula iya kunabela ezantsi. IHuasteca kunye neMpuma-mpumaUkusuka eCoahuila ukuya eVeracruz, nge-avareji ye-20 ukuya kwi-50 mm. Kwangaxeshanye, amazwe akumntla-ntshona, entshona, nakumbindi, kuquka IChihuahua, iSonora, iLizwe laseMexico kunye neSixeko saseMexicoZiza kurekhoda iimvula kunye neziphepho ezizimeleyo ezineengqimba ezi-5 ukuya kwi-30 mm.
Uqikelelo lokuqala kweveki elandelayo lubonisa ukuba imozulu engazinzile iya kuqhubeka, kunye nemvula enkulu kunye nemvula enkulu e- Zacatecas, Durango, Sinaloa, Nayarit, Jalisco, Guanajuato, Querétaro, Hidalgo, State of Mexico, Mexico City, Tlaxcala, Puebla, Veracruz, Oaxaca, Chiapas and TabascoOku kubonisa ukuba umoya obandayo kunye nemijelo yoxinzelelo oluphantsi iya kuhlala isebenza.
Imimoya enamandla, izivuthuvuthu zothuli kunye namaza aphezulu
Enye into ebalulekileyo iya kuba umoya ovuthuzayo owandileyoKumazwe asemantla, kulindeleke ukuba umoya ukhawuleze ngaphezu kwe-70 km/h xa kufika i-front, kwaye imimoya efikelela kwi-110 km/h inokwenzeka kwiindawo ezineentaba kunye nemiqolomba ekufutshane nomda, apho kunokubakho izivuthuvuthu zothuli ezinciphisa ukubonakala endleleni.
Kwizinto ezifana Chihuahua, Coahuila, Nuevo León, Tamaulipas, Durango, Zacatecas kunye neSan Luis Potosà Kulindeleke imimoya enamandla, enxulunyaniswa nokutyhalwa komoya we-polar kunye nokusebenzisana kwawo nemijelo yasekuhlaleni enoxinzelelo oluphantsi. Le mimoya iya kuqinisa ukuziva ubanda kwaye inokuba negalelo kwizivuthuvuthu zothuli kwiindawo zasentlango nakwiindawo eziphantse zibe yintlango.
Kulo I-Isthmus kunye neGulf yeTehuantepec Kulindeleke ukuba kubekho umoya onamandla ngokukodwa, ohamba ngesantya esiphakathi kwe-80 ukuya kwi-100 km/h, ohamba namaza aphezulu angama-3 ukuya kwi-4 eemitha. Ezi meko zinokubangela ukuba kube nzima ukuhamba kwiinqanawa ezincinci kwaye zikhokelele ekuvalweni kweminye iminyango ngononophelo.
Kwindawo ephakathi yelizwe, kuquka ummandla waseBajÃo kunye neNtlambo yaseMexico, umoya nawo uya kudlala indima ebalulekileyo. NgoMgqibelo, umoya ungafikelela kwi-60 ukuya kwi-70 km/h, okwaneleyo ukuhambisa amasebe, imiqondiso yokukhanya, kunye nokudala umoya obandayo ophantsi kusasa nangokuhlwa.
Abasemagunyeni bacebisa ukuba kugcinwe izinto eziphezu kophahla nakwiibhalkhoni, kuphetshwe ukuzikhusela phantsi kweebhodi ezinkulu okanye imithi emikhulu ngamaxesha omoya onamandla kakhulu, kwaye kuhlale kuphaphelwe izilumkiso zoKhuseleko loLuntu kwiindawo ezibonakala kakhulu.
Umahluko phakathi kobushushu kunye nembonakalo yemihla ezayo
Ukufika kwe-cold front 42 kwakhona kugqamisa ukutshintsha kwemozulu ephezulu ngeli xesha lonyaka. Nangona umntla kunye neendawo eziphakamileyo ziza kuba namava okuhla kobushushu kunye neqabaka kusasa, iindawo ezikunxweme ziya kuqhubeka nokuba namaqondo obushushu afana nehlobo, kunye namaxabiso anokuthi kwezinye iindawo zasemntla-ntshona afikelele okanye adlule kuma-40°C.
Kumantla-mpuma, ubushushu buza kuthomalaliswa kakhulu yimvula kunye nokugqunywa ngamafu, apho amaqondo obushushu aqala kwi-25 ukuya kwi-33°C kwaye aphantsi ukusuka kwi-10 ukuya kwi-18°C. Ngaphakathi, kulindeleke ukuba amaqondo obushushu aphakame ukusuka kwi-15 ukuya kwi-25°C ngoMgqibelo, angaphantsi kancinci koko bekuya kuba yinto eqhelekileyo ekupheleni kukaMatshi, ngaphambi kokuba kuqikelelwe ukuba imozulu ibuyele umva kancinci ngeCawa kwimimandla esemantla.
Iimodeli eziqikelelayo zibonisa ukuba, kwixesha elizayo Iintsuku ezi-7 ukuya kwezi-15Umkhwa wokunyuka kwezivuthuvuthu eziphakathi uza kuqhubeka kwicandelo elisezantsi-mbindi welizwe, kunye nee-anticyclones ezibuthathaka emantla kunye nobuninzi bomoya ophantsi. Olu hlobo lomoya luvumela amaxesha aphindaphindiweyo obushushu obuphantsi, imvula, kunye nomoya ovuthuzayo, ubuncinci ekuqaleni kuka-Epreli.
Kule meko, iingcali zemozulu zigxininisa ukuba imeko "yentwasahlobo eshushu kakhulu" okanye imbalela ebanzi kulo lonke ilizwe akufuneki ithathwe njengento elula. Umahluko phakathi kwamaxesha ashushu kunye namaxesha abandayo nanemvula unokuba yinto eqhelekileyo kwiiveki ezizayo.
Ngenxa yesi simo, uluntu luyacetyiswa Hlala ubukele izibhengezo ezisemthethweniNxiba shushu kusasa xa kubanda, phepha utshintsho olukhawulezileyo kubushushu, kwaye unikele ingqalelo ekhethekileyo kubantu abasengozini njengabantwana, abantu abadala, kunye nabo banesifo sokuphefumla, njengoko olu hlobo lwesifo somkhuhlane osemva kwexesha ludla ngokunyusa umngcipheko womkhuhlane kunye nezinye iingxaki zempilo.
Ngokufika kwe-cold front 42, iMexico iza kujongana nempelaveki yomahluko ophawulekayo: ngelixa amanye amazwe eza kujongana Amaqondo obushushu angaphantsi kwe-zero, iqabaka, imvula enkulu kunye nemimoya enamandlaEzinye ziya kuqhubeka nemeko-bume eshushu, ingakumbi kumanxweme nakwiindawo zeYucatan Peninsula; le ndlela yokuziphatha, engaqhelekanga, ihambelana nentwasahlobo ebonakala ngotshintsho olukhawulezileyo kwaye ifuna ukuhlala uqaphela ukuguquka kwemozulu imihla ngemihla.
