El I-Cold Front 48 ijongeka njengenye yezona ziqendu zibalulekileyo ze- isiqingatha sokugqibela sexesha lonyaka yeenkqubo zangaphambili kwi-emantla e-hemisphere. Iqhutywa ngumoya omkhulu we-polar, ifika emva kweentsuku ezininzi zobushushu obungaqhelekanga kunye nokuzinza komoya, nto leyo etshintsha kakhulu imozulu kwiindawo ezininzi zaseMexico, ingakumbi emantla, emantla-mpuma, empuma nakwiindawo eziphakathi kwelizwe.
Le nkqubo yangaphambili, eqikelela ukuba iza kuba isiqalo sokugqibela esibandayo sesiziniAyizukuzisa kuphela isiqabu kubushushu, kodwa ikwazisa ukwanda kwemvula kunye neendudumoisichotho kunye nomoya onamandla. Ukudibana nezinye izinto ezenzeka emoyeni kuya kuvelisa Kukho umahluko omkhulu phakathi kweendawo ezinemozulu epholileyo kunye nezinye eziya kuqhubeka zifumana amaqondo obushushu aphezulu..
Iza kufika nini iCold Front 48 kwaye iza kuhamba njani?
Ngokwezilumkiso zemozulu, I-Cold Front 48 iza kuqala ukusondela kumda osemantla phakathi kokuphela kuka-Epreli neentsuku zokuqala zikaMeyi.besebenzisa ithuba lokudlula kwe imijelo yejethi ye-polar ne-subtropicalUkufika kwayo kuya kwenzeka kwimeko elawulwa liza lobushushu obukhulu kunye nobukho bokujikeleza kwe-anticyclonic kumanqanaba aphakathi omoya.
Kwinqanaba lokuqala, phambili Oku kuza kusondeza amazwe asentla nakumntla-ntshona.apho iya kudibana nomsele okumgangatho ophezulu kunye umgca owomileyo okwimpuma-mpuma yelizweOlu dibaniso luya kunceda ukwakheka kwamaqela amafu axineneyo, izivuthuvuthu ezihlala ixesha elifutshane kodwa ezinamandla, kunye notshintsho lomoya olukhawulezileyo.
Njengoko inkqubo iqhubeka, Iza kunwenwela emantla nasemantla-mpuma, ngaphambi kokuba iye kwiGulf of Mexico nakumzantsi-mpuma, nto leyo ekwachaphazela Usingasiqithi YucatanKulo mmandla, umahluko phakathi komoya obandayo nowomileyo ovela kwiindawo ezisezantsi kunye nomoya ofudumeleyo nofumileyo ovela kwiindawo ezishushu uya kuba yimbangela yokungazinzi.
Iimodeli zixela kwangaphambili ukuba, ekupheleni kobomi bazo obuluncedo, I-Cold Front 48 ithanda ukuba phantse zimi phezu komntla-mpumaibuthathaka kancinci kancinci kodwa isakwazi ukuvelisa imvula kwaye igcine indawo epholileyo kunesiqhelo kwiindawo ezahlukeneyo.
Ukusebenzisana ne-heat wave kunye ne-anticyclonic circulation
Ngaphambi kokufika kwesixeko, Ukujikeleza kwegazi okuchasene ne-cyclonic kumanqanaba aphakathi omoya kugcina ukubaluleka okukhulu ubushushu obuphezulu kulo lonke ilizwe. Le anticyclone ibonakaliswa ngumoya ohlayo, isibhakabhaka esicacileyo, ukungabikho kwemvula phantse ngokupheleleyo, kunye nobushushu obushushu ukuya kobushushu kakhulu kumazwe angama-29 ubuncinane.
Imimandla yasentshona, esembindini, neyasemazantsi, efana Sinaloa, Jalisco, Michoacán, Guerrero, Oaxaca okanye ChiapasAmaqondo obushushu aphezulu kakhulu, apho amaqondo obushushu aphezulu adlula ama-40°C kwezinye iindawo aze afikelele okanye adlule ama-45°C. Le meko ibangele imeko-bume eyomileyo, imitha yelanga enamandla kakhulu, kunye nobushushu obushushu obuphuma kwiintsuku.
Ngokusondela kweCold Front 48, I-anticyclone iza kuqala ukuya kwiGulf of MexicoOlu hambo luza kwenza kube lula ukwehla kancinci kancinci kwamaqondo obushushu, ingakumbi kumantla-mpuma, empuma nakumbindi, kwaye luza kuphawula ukuqala kobuthathaka beqondo lobushushu elalichaphazela inxalenye enkulu yalo mmandla.
Ungquzulwano phakathi umoya oshushu kakhulu okhoyo ngaphambili kunye nomoya ophantsi ohamba nomphambili iya kuvelisa umahluko obalulekileyo wobushushuKwiiyure ezimbalwa nje, ziya kukwazi ukusuka kubushushu obugqithisileyo ziye kwindawo epholileyo kakhulu, ingakumbi kumazwe asemantla nakumantla-mpuma, apho ubushushu buya kubonakala ngokucacileyo.
Kwangaxeshanye, ukufuma okuziswa kwiindawo ezishushu kuya kuba negalelo imvula iya kuba rhoqo kwaye ibe namandlaukukhawulezisa utshintsho oluya kwindlela eqhelekileyo yexesha lemvula elizayo.
Amazwe achaphazeleke kakhulu: imvula, isichotho nomoya onamandla
Indlela yenkqubo yangaphambili iya kubangela Iziphumo zeCold Front 48 zisasazwa ngokungalinganiyo, apho ezinye iindawo zichanabeke kakhulu kuzo izaqhwithi ezinzimaimimoya enamandla kakhulu kunye nokwehla okukhulu kwamaqondo obushushu.
Kwinqanaba lokuqala, amazwe aseSonora, eChihuahua naseCoahuila Baza kuchatshazelwa yimvula kunye nemvula enkulu yasekuhlaleni, ehamba neziphango zombane kunye isichotho esinokubakhoUmoya nawo uza kudlala indima ebalulekileyo, kunye neemvuthuvuthu ezinokufikelela okanye zidlule kwi-80 km/h kwiindawo ezivulekileyo.
Okulandelayo, inkqubo iya kwenza ubukho bayo buvakale ngakumbi I-Coahuila, iNuevo León kunye neTamaulipasapho imvula enkulu ejikeleze iimilimitha ezingama-50 ifunyenwe khona, umsebenzi wombane, kunye namathuba aphezulu okuba ukwakheka kwezivuthuvuthu okanye iivortices kwiindawo ezisemantla zala mazwe mathathu.
Uqikelelo lubonisa nokuba Iishawa ezisasazekileyo eNuevo León naseTamaulipas malunga nokufika kwelo cala, elinokuthi ukwenza kube nzima ukuhambahamba, ikhuthaza izikhukula zasekuhlaleni kwaye inciphise ukubonakala endleleni, ingakumbi emva kwemini nangokuhlwa.
Ukuya phambili emazantsi nasempuma, IVeracruz, iOaxaca kunye neChiapas Ezi ndawo zivela njengezinye zeendawo ezinomngcipheko omkhulu wemvula enkulu, nto leyo enokubangela ukuba kwiindawo ezithile kubekho izikhukhula, ukugcwala kwemifula kunye nokudilika komhlaba kwiindawo ezithe tyaba ezingazinzanga.
Imeko ethile eNuevo León nakumntla-mpuma welizwe
Enye yeendawo apho impembelelo yenkqubo iya kubonakala kakhulu iya kuba ilizwe laseNuevo León, ingakumbi indawo yalo yedolophu kunye nemimandla ekufutshaneAmagunya oKhuseleko loLuntu alumkisile ukuba impelaveki ephawulwe kukudlula kwelo cala iya kuhamba notshintsho olucacileyo kwimozulu.
Bayalinda imvula ekhaphukhaphu ukuya kwephakathiEzi mvula zilindeleke, ikakhulu emva kwemini nangokuhlwa, zihambelana nexesha lokudibana okukhulu phakathi komphambili kunye nomjelo womoya ophantsi. Imvula iya kukhatshwa ngumoya onamandla, ngakumbi ochaphazela imimandla esemantla, yedolophu enkulu, empuma, kunye nemimandla ekhula iziqhamo zesitrasi kweli lizwe.
Ukongeza kokungazinzi komoya, Ubunzima bomoya we-polar obunxulumene neCold Front 48 buza kubangela ukwehla kwamaqondo obushushuIsiphumo esibonakalayo kakhulu siya kuba semahoreni asekuseni. Amaqondo obushushu aphantsi kulindeleke ukuba abe malunga ne-14-16 °C kwimimandla eseMantla, eMetropolitan, eCitrus naseMzantsi; 16-18 °C eMpuma; kwaye phakathi kwe-8 ne-10 °C kwiindawo zeentaba.
Olu tshintsho lunokubangela utshintsho olukhawulezayo kubushushu obubonwayo imini yonkeukutshintsha ukusuka kwiimeko ezifudumeleyo emva kwemini ukuya kwiimeko ezibandayo ebusuku. Olu hlobo lokuguquguquka lubaluleke kakhulu kumaqela abuthathaka, njengabantu abadala okanye abantwana.
Ngenxa yesi simo, uKhuseleko loLuntu lugxininisa kwimfuneko yokuba Kuphephe ukuvezwa ngokungeyomfuneko kutshintsho olukhawulezileyo lobushushuQhuba ngononophelo xa kukho imvula okanye imimoya enamandla kwaye unikele ingqalelo kwizilumkiso ezikhutshwa ziinkonzo zaseburhulumenteni.
Ukwehla kobushushu, isiganeko "seNorte" kunye nomahluko omkhulu
Ubukho bomoya we-polar ohamba phambili buya kuba negalelo elikhulu kwinto yokuba ukwehla okuphawulekayo kobushushu kwenzeka emantla, emantla-mpuma, empuma nakwinxalenye yezikoKwezinye iindawo, imozulu iya kuba shushu kakhulu ize iphole emva kweeyure ezingama-24 ukuya kuma-48.
Kumanqanaba aphezulu kumazwe afana IBaja California okanye iDurango Kulindeleke ukuba amaqondo obushushu aphantsi angaphantsi kwe-0°C, kunye namaxabiso anokuba phakathi kwe--5 kunye ne-0°C kunye neqabaka. Amaqondo obushushu aphakathi kwe-0 kunye ne-5°C nawo alindeleke, kunye neqabaka enokwenzeka kwiindawo zeentaba zase Sonora, Chihuahua, State of Mexico, Tlaxcala and Puebla.
Okwangoku, kwezinye iindawo zelizwe Amaqondo obushushu aphezulu kakhulu aya kuhlala ekhoKwimimandla efana neSinaloa nakwezinye iindawo zaseDurango, amaqondo obushushu anokudlula kwi-45°C, nakwiindawo ezinkulu zaseSonora, eChihuahua, eCoahuila, eNuevo León, eZacatecas, eSan Luis Potosí, eNayarit, eJalisco, eMichoacán, eQuerétaro, eHidalgo, ePuebla, eGuerrero, e-Vercruuliaa, e-Oliana, e-Orica ECampeche, naseYucatán, amaqondo obushushu emini aphakathi kwama-40 nama-45 ngokukaCelsius alindelekile.
Le meko igxininisa ukuguquguquka okukhulu kwemozulu okunokwenzeka ngaxeshanye kwangelo xesha linye: ngelixa ezinye iindawo zijongene nemozulu yeqabaka neyobusika, ezinye ziyaqhubeka nobushushu obuphezulu kunye nomngcipheko wokuhlaselwa bubushushu kunye nokuphelelwa ngamanzi emzimbeni.
Kwelinye icala, ukudlula kwenkqubo yangaphambili kuya kuyenza isebenze Umsitho womoya "waseNorte" kunxweme lwaseTamaulipas naseVeracruzNgemimoya enamandla enokufikelela phakathi kwama-70 nama-90 km/h kunye namaza anokufikelela ukuphakama ukuya kwiimitha ezine. Kunxweme lwaseTabasco nakwi-Isthmus nakwiGulf of Tehuantepec, kulindeleke imimoya engama-60 ukuya kuma-80 km/h kunye nolwandle olurhabaxa.
Imvula engakumbi kunye nokuphela kancinci kancinci kweqondo lobushushu
Iintsuku zokuqala zikaMeyi ziya kuphawulwa ukwanda okucacileyo kwemvula kwiindawo ezininzi zelizwe. Ubunzima bomoya we-polar obunxulumene nomphambili kunye nokungena komswakama wetropiki kuya kunceda iziphepho, iimvula, kunye nemvula enkulu, okunciphisa ubude kunye nobunzima beziganeko ezintsha zobushushu obugqithisileyo.
Kwisiqingatha sokuqala senyanga, ukudibana kwemozulu ebandayo yakutshanje kunye nokuhamba kwamanzi okufumayo okuvela kwiPasifiki kuya kuba negalelo ukudibanisa utshintsho oluya kwixesha lemvulaKule meko, ukwenzeka kwenkanyamba yokuqala yetropiki yexesha lonyaka elunxwemeni phakathi kweChiapas neJalisco akunakuphetshwa, nto leyo eya kwandisa imvula kakhulu kwisiqingatha esiphakathi nesisemazantsi salo mmandla.
Kumantla nasemantla-mpuma, amazwe afana Nuevo León Imvula ingaqokelelana phakathi kweemilimitha ezingama-50 ukuya kuma-75, kwaye ubuninzi bayo bufikelela kwiimilimitha ezili-150 kwiindawo ezineentaba. Ukusasazwa kwemvula ngokungalinganiyo kunokukhokelela ekunciphiseni imbalela kwezinye iindawo kunye neengxaki zezikhukula kwiindawo zasezidolophini ezingafumani manzi ngokwaneleyo.
Kwelinye icala, imimandla yasentshona-ntshona kunye neendawo zasentshona ziya kubhalisa. Imvula encinci ngakumbi, ngokuhambelana nemozulu eqhelekileyonangona kukho utyekelo lokwanda njengoko inyanga iqhubeka. Olu tshintsho luyinxalenye yotshintsho kwindlela umoya ohlala usenzeka ngayo ngeli xesha lonyaka.
Ngokubanzi, uMeyi ulungiselela ukuba yinyanga ukwanda okuqhubekayo kwemvula kunye nokuthomalalisa ubushushu obugqithisileyoNangona kunjalo, iziqendu ezithile zobushushu obuphezulu zisenokwenzeka, ingakumbi apho i-anticyclone iqhubeka nefuthe layo.
Yintoni i-cold front kwaye isebenza njani i-polar air mass?
Ukuze uqonde ngcono okwenzekayo, kubalulekile ukukhumbula ukuba Indawo ebandayo yindawo yokudibana phakathi komoya obandayo kunye nomoya ofudumeleyo.Xa umoya we-polar usiya phambili uze ungene phantsi komoya oshushu okanye oshushu, uyawutyhalela phezulu, nto leyo ebangela ukuba kubekho amafu, iimvula, kunye nezivuthuvuthu ezithe nkqo.
La Ubunzima bomoya obuphantsi obunxulunyaniswa neCold Front 48 Liyindawo enkulu yomoya enobushushu obuphantsi kunye noxinzelelo oluphezulu, oluveliswa kwiindawo ezikufutshane neepali. Njengoko isiya kwiindawo ezisezantsi, itshintsha kakhulu imeko yemozulu: yehlisa ubushushu, itshintsha indlela yomoya, kwaye ivula umnyango weziganeko zemvula kunye nemimoya enamandla.
Kwimeko ethile yesi siganeko, icala elingaphambili Ayisebenzi yodwa.Kunoko, isebenzisana nomngxuma ongaphezulu ophantsi koxinzelelo, imijelo yejethi ekumgangatho ophezulu, kunye nomngxuma okumgangatho ophezulu. Olu dibaniso luchaza isizathu sokuba sibone yonke into ukusuka kwiqhwa kwiindawo eziphakamileyo ukuya kwizivuthuvuthu ezinesichotho kunye nemimoya enamandla kwiindawo ezisezantsi.
Ixesha elibandayo eMexico lihlala likho ukususela ngoSeptemba ukuya kuMeyikunye nolandelelwano lweenkqubo zangaphambili ezingena zivela emantla nasemantla-mpuma. Ngokwezibikezelo zalo mjikelo, kuqikelelwe malunga neembalo ezingama-48, ngoko ke esi siganeko sikwinxalenye yokugqibela yokubala okuqikelelweyo.
Ngaphezu koko, xa ezi nkalo zihambelana izinto ezishushu ezifana namaza okanye iinkanyambaIsiphumo sinokuba kukwanda kwemvula kunye namathuba amakhulu eenkqwithela ezinkulu, into ekufuneka iqwalaselwe ngakumbi njengoko sisondela ekuqaleni kwexesha leenkanyamba zasetropiki.
Iingcebiso kunye namanyathelo okuthintela iCold Front 48
Ngenxa yemeko eguquguqukayo kangaka eneemeko ezitshintshayo, abasemagunyeni bagxininisa ukuba Ukulungiselela nobulumko kubalulekile ukunciphisa iingozi. Akupheleli nje ekuzikhuseleni kwiingqele, kodwa nakwimvula enkulu, umoya, namaza kwiindawo ezikunxweme lolwandle.
Iinkonzo zikaxakeka zicebisa idyasi enemalekoOku kuquka impahla ekhusela intamo, izandla, nentloko, ingakumbi ekuzeni kokusa nasebusuku, xa ubushushu bubonakala kakhulu. Kwimimandla apho kulindeleke ukuba iqabaka, kubalulekile ukukhusela abantu abasengozini nokuqinisekisa ukuba amakhaya kunye neendawo zokukhosela zigcina ubushushu obufanelekileyo.
Ekhaya, kuyacetyiswa Jonga uphahla, imibhobho engaphantsi komhlaba kunye nemijelo yamanzi amdaka Ukuthintela ukuvuza kunye neengxaki zokuqokelelwa kwamanzi ngexesha leenkqwithela, kuyacetyiswa ukuba ukhusele izinto ezinokuphetshethwa ngumoya, ezifana neembiza zeentyatyambo, ifenitshala ekhaphukhaphu, okanye izinto ezikhululekileyo ezikwii-terraces nakwiiphahla.
Endleleni, ukubaluleka Qhuba ngononophelo olukhulu xa lina imvula okanye umoya uvuthuza ngamandla.Nciphisa isantya sakho, yonyusa umgama wakho olandelayo, kwaye uphephe ukunqumla iindawo ezikhukuliswe ngamanzi okanye iindawo ezineedama ezinzulu. Ukubonakala okuncinci kunye nendlela etyibilikayo kunokunyusa umngcipheko weengozi.
Okokugqibela, ibalulekile kwizixeko nakwiindawo zasemaphandleni Hlala unolwazi ngokusebenzisa uqikelelo olusemthethweni evela kwiNkonzo yeSizwe yeMozulu kunye nohlaziyo oluvela kwiCivil Protection, kunye nokuphendula kuzo naziphi na izilumkiso malunga nokwakheka kweenkanyamba ePacific okanye ukuvuselelwa kwezilumkiso zemvula enkulu kunye nemimoya enamandla.
Ukudlula kweCold Front 48 kuza kuphawula utshintsho olukhulu kwimozulu, kudibanisa ukuphela kancinci kancinci kobushushu kunye nokwanda kwemvula, izivuthuvuthu kunye nemimoya enamandla kwimimandla eyahlukeneyo; isiganeko, ngaphaya kokukhululeka kobushushu kwezinye iindawo, esiya kufuna ukuqaphela iimeko ezitshintshayo kunye nokuthatha amanyathelo afanelekileyo okujongana ngokukhuselekileyo nokuphela komoya obandayo wexesha langaphambili.
