Ngaphakathi kweziganeko zemozulu kunye neentlobo zemimoya kukho esinayo squall. Luhlobo lomoya olubonakaliswa ngokukhawuleza kwaye ngesantya esomeleleyo kakhulu. Ixesha lolu hlobo lomoya lufutshane kakhulu kwaye lwenzeka kwiindawo zobume obunomdla wokubanda.
Kule nqaku siza kukuxelela zonke iimpawu, imvelaphi kunye nedatha eyahlukileyo malunga ne-squall.
Iimpawu eziphambili
Okokuqala, bona ukuba squall ithetha ntoni. Kwintsimi yemeteorology, oko kuthetha ukuba luhlobo lomoya olubonakala ngesiquphe, ngokukhawuleza nangamandla amakhulu. Ukuhlelwa kwayo kuyahluka ngokuxhomekeke kwisantya somoya. Oko kukuthi, ukuze umoya ubekwe njengophakathi kufuneka ibe nemimoya emalunga neekhilomitha ezingama-40 ngeyure.
Nangona kunjalo, kuxhomekeke kwilizwe esikulo, ingcungcu ibizwa ngamagama ahlukeneyo. EMexico ihlala ibizwa ngokuba yiNkanyamba, eVenezuela "iVaporon", iArgentina "iSaqhwithi", eBrazil "iTurbiña", ePeru "iSolplo", eColombia "yiRafagueta". Kunokuthiwa, ngokwemiqathango ngokubanzi, lo moya umiselwe njengohlobo lomoya olunethuba elithile lexesha elingaphezulu okanye elingaphantsi kwesiqingatha somoya onamandla onokuba nawo kumgama othile.
Esi squall sinokukhula kulwelo olunje ngamanzi kwaye kulapha ukuba bazibonakalise ekusebenzeni kokuhamba kakuhle kwamanzi apho ubunzima kunye nesantya zihlala zihleli. Olu hlobo lomoya lungabonwa kukudumba kunye nemisinga yamanzi ekhawulezayo. Ngamanye amaxesha, ii-eddies ezingaphezulu zinokwenza, ezinje ngemisinga yomsi. Le misinga izalwa ngeetshimini okanye ikwafumaneka kwinkungu ngexesha lesiphango, phakathi kwabanye.
Imigca ye-squall kunye nekhephu
Xa sithetha ngeqhekeza lekhephu sithetha ngombane obanda kakhulu onesantya esiphezulu kunye nexesha elifutshane kakhulu. Xa unendawo enamaqondo obushushu asezantsi, umxholo womoya ubakho ngamasuntswana eoksijini efriziwe. Le mijelo ine-turbid kakhulu, ethintela ukubonakala okuyinxalenye kunye nokugcwele ngokuxhomekeke kubunzulu bayo.
Bahlukile kukuphoswa ngumoya okokoko banethuba lokuba Kuluhlobo lwemizuzu eyi-15-20. Ngokwesiqhelo olu hlobo lweziganeko zemozulu lubangela iingxaki ezinkulu kwiindawo ezenzeka kuzo. Oku kwenzeka ngakumbi kwezi ndawo zinamaqondo obushushu angaphantsi kwe-0 degrees. Zikhatshwa yimvula ngohlobo lwamahlwantsi ekhephu akhanyayo kakhulu kwaye ahamba ngesantya esiphezulu. Banokugcwalisa indawo ngekhephu ngaphandle kwexesha. Ungayibona ngokulula indlela abagubungela ngayo uphahla lwezindlu, iindlela, iindlela kunye nezithuthi. Bayingozi ngenene ukuba bakubambe ungalindelanga.
Imigca ye-squall ibandakanya ubukho bezaqhwithi zombane ezininzi ezidibanayo. Inokuphuhliswa ngokudibeneyo kwaye idibanisa iifonti ezimbini ezishushu nezibandayo. Ukuze olu hlobo lweziganeko zemozulu ziveliswe ukungqubana kwemida yamaqondo obushushu ahlukeneyo kuyafuneka. Umgca we-squall unokwenza emva kokuba isiphango sahlule kwiindawo ezininzi.
Kukho iintlobo ezininzi zemigca ye-squall. Luhlobo lobumnyama obulayishwe ngomphunga kunye nomoya okhula ngokukhawuleza emva koko uwe. Le ntshukumo yomoya ikhawuleze kangangokuba ayivumeli amanzi ukuba adibane kwaye abangele imvula.
Olunye uhlobo lwe-squall ekhoyo luhlobo lwe ilifu elimnyama lilayishwe sisixa esikhulu somphunga wamanzi. Lo mphunga wamanzi uhlala kwindawo ephezulu yomoya ngendlela ezinzileyo ixesha elifutshane kakhulu. Ngalo lonke eli xesha kunokwenzeka ukuba wandise imimoya iye kwezona ndawo ziphambili kwaye bakhusela kancinane kakhulu njengangaphambili. Kwenzeka ngokukhawuleza kangangokuba akuvumeli ukufuma kwamanzi.
Uninzi lwale mimoya lwenzeka e-United States kwaye kumiselwe ukuba uninzi lweendudumo ezikhawulezayo nezinamandla ziyenziwa ngemigca ye-squall. Bahlala bedlula ngokukhawuleza kuloo ndawo bavela kuyo, balayishwe ngokufuma.
Umahluko phakathi kweengcwangu kunye neenkanyamba
Kulula ukudida ezi ntlobo zeziganeko zemozulu kuba zinemvelaphi efanayo. Ziyefana neziganeko zemozulu okoko ukubonakala kobukho kukwafana kakhulu. Zombini zinomahluko omkhulu kwaye luluqeqesho lwazo. Ukufuduswa kunokwahluka okwahlukileyo. Izaqhwithi zisekelwe koxinzelelo olunamandla lomoya olonyuka ngesantya esiphezulu kwaye nje ukuba bahlangane ulungelelwaniso luqala ukujikeleza ngokukhawuleza okukhulu. Oku kuvelisa ukonyuka komoya ohamba nalo lonke uthuli nesanti emhlabeni. Amandla akhulu kakhulu kangangokuba angaphakamisa izithuthi ezikhulu okanye izilwanyana ukuba zingqubana nokunyuka komoya.
Kwimeko apho inkanyamba yenzeka elwandle, yenziwa ngendlela efanayo kodwa umahluko wokuba, emanzini ukuvelisa amandla kunye nokufikelela kubude obufikelela kwi-km. Ukususela kumaxesha amandulo, iimvula zeentlanzi zazibhekiswa kuzo njengezinto ezinxulumene noothixo. Namhlanje kuyaziwa ukuba imvula yeentlanzi inxulumene nobukho beenkanyamba zolwandle.
Njengoko sisazi ukuba zithini iziphikiso, sinokuthi ngokuxhomekeke kumandla akhupha, iyafana kakhulu nenkanyamba. Nangona kunjalo, ixesha alidluli kwimizuzu engama-30 kwaye kunokubangela umonakalo omkhulu nokukhuthaza isiphithiphithi ngexesha elifutshane kakhulu. Xa eli xesha lidlulile, ixesha liqala apho i-squall iqala ukubuthathaka kunye nokunciphisa inani lemvula. Banikezela ngumoya ongadluli kwimizuzwana eyi-15-30 kwaye banokufikelela kwi-200 km / h yesantya esiphezulu. Ukuba umntu udibana nenye yezi zinto, banokulimala kakhulu.
Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga ne-squall kunye neempawu zayo.
