Kuyini ukucindezeleka polar?

ukucindezeleka Polar - ukwakheka zemvelo. Lezi izinhlelo zemvelo ukunikeza futhi ukukhomba usebenzisa imiyalezo Meteorological ezivamile akuzona ngakho elula. Ngakho-ke, banciphisa ematilosini, emoyeni zenethiwekhi nezinye izinto ezenziwa abantu ezindaweni ezisenyakatho. Indlela ezingalindelekile futhi kuyingozi ukucindezeleka polar, into, ake step by step.

Umlando yokutholakala

ukucindezeleka Polar - into ukuthi libhekisela uhlelo sezulu elincane, okuyinto isikhathi esifushane futhi esibonakala ngokuqina ingcindezi ongaphakeme. Yakheke phezu izilwandle e zombili ama- eceleni ngaphambili main polar. izifundo Early wasikisela ukuthi isizathu esiyinhloko ivela khona - ukuntengantenga ezishisayo. Kodwa le nkulumo yathathwa ekude kakhulu ngokoqobo. Kamuva safunda nemibandela kumiswa. Ngokokuqala ngqá lolu hlobo uhlelo lwemvelo satholakala izithombe Meteorological eziye zitholakale ku-yalolucwaningo 60 leminyaka elidlule.

Ngezinye Ezindaweni eziphakeme, ochwepheshe, impela kwase lonke okuningi vortex amafu. Bakhandwa kuyofikwa phezu izindawo ice-free eshiwo ngenhla ezilwandle, phezu Labrador, kanye iGulf of Alaska. It is waphawula ukuthi ukucindezeleka polar kwashabalala basheshise ngokwanele ngesikhathi ichweba. nozakwethu Nordic zasezindaweni Antarctic ngokuvamile buthaka, ngoba zonke kanye nezwekazi uhlangabezana iyehla iyenyuka ngaphansi kwamazinga ahlukahlukene okushisa. Nakuba ngezinye izikhathi ngisho ngaphakathi Southern Ocean bangase bazibone Dynamics zalesi simo.

izithombe Satellite asivumela ukuba baphethe ngokuthi ukucindezeleka polar libhekene ezihlukahlukene bobunjwa ifu ukuthi zingase zimiswe kusuka bands Kuvunguza lwamafu esigubuzele isikhungo noma eduze ngaphambili polar ukuthatha isithombe ukhefana. Empeleni, kuye isakhiwo kanye nezinga necala imihlola sezulu, umfutho kanye nesivinini esiphelweni.

Mshini kumiswa

Lapho phambi polar iqala yayo ukuthuthukiswa wave Ukungena sithuthukisi ecucuza e tropical imvelo emoyeni mass ekhiqizwa ukucindezeleka polar. Uma ucabangela uhlelo ukukhuthazwa ohlangothini empumalanga, isikhwishikhwishi efudumele, ogama emoyeni uzama wokukhipha abandayo ihlukile kune okuphambene, okuyinto omlandelayo waxosha phansi kwelanga azithinta uquqaba. Waba yini umphumela walesi ukunyakaza kukhona izakhi okuphambene kuba ingcindezi ukunciphisa ngaphezulu, isikhungo okuyinto lizungezwe isobar ukuthi umoya lipheshulwa liyiswa ngapha nangapha crosswise.

Ngenxa yalokho, umoya ugeleza umnyombo ukucindezeleka langaphezulu anda ngobusuku obubodwa. Njengoba le nqubo phambi abandayo osondela efudumele, okuholela occlusion isigaba. Nakuba kunezinkolo emoyeni lokushisa ongaphakeme futhi phezulu ukunyakaza cyclonic yomdlali, elikhonjiswa nge- isobar nomoya isiqondiso phezu kukhona omunye phambi Ngokuphambene njengoba mhosha ohlukanisa ukusakaza engenayo, lisendaweni ezingemuva ukucindezeleka. Lokhu kuholela yokushintsha ngaphambili. Kuye uhlobo izinqubo sokunquma umdlalo yokuguqukela kwesinye isimo occlusion kuyinto okubandayo noma efudumele. Kuleli kuncike ukubonakaliswa lwangaphandle isishingishane ezweni.

isikhathi Ukuze

Phakathi ukhona lolu hlobo lwesistimu sezulu incike esingakanani bezikhali amandla kufanele siguqulwe energy kinetic. ukucindezeleka Polar phansi lapho phakathi laphakathi emoyeni etholakala endaweni, Ngokuphambene ubalekela ingcindezi ongaphakeme kanye eliphezulu. kuyadamba yayo okusheshayo kwenzeka uma displacement we ebusweni ice noma umhlaba isilinganiselo. Banikezwe ubuhlobo ngqo kuyanda umoya onamandla imimoya, kungaba kakhulu ukuthonya sezulu.

Imiphumela sezulu

Ngenxa izikhatha zomoya oshisayo liphume kancane kancane nezimpi, inqobo nje uma isifinyelele ukuzinza, ukwakheka amafomu ifu egqinsiwe. Uma avele amafu esibhakabhakeni Cirrus ke ohlangothini front efudumele. Esesondela namafu ngezansi bese okukhulu ngaphezulu. Ngokuvamile zokulala kubonisani imvula enhle ekugcineni liphenduka imvula esindayo. Futhi eyodla kakade singalindela esibhakabhakeni libalele Cumulus kulungiselelwa.

I kusondela umsinga abandayo ngokuzumayo sezulu sishintsha. Emazulwini kukhona amafu cumulonimbus, injengombhoshongo, ngokuletha, njengoba umthetho, izimvula ezisindayo futhi nokuduma. Kungazelelwe, isiqondiso somoya lishintshwa kuya enyakatho noma enyakatho-ntshonalanga. Isimo isiphepho eba ngokuzumayo futhi isikhathi esifushane.

Uyini umehluko?

Uyini umehluko frontal ukucindezeleka Nenkabazwe eningizimu ngokwalo efana eNorth? Cishe lutho, nakuba kukhona kuhlukane uhlu lozalo olubalulekile. Esimweni sokuqala, umoya ngezihluthu efudumele uphendulela enyakatho kuyofika ngasenyakatho-ntshonalanga, futhi emakhazeni - kusuka entshonalanga kuya eningizimu-ntshonalanga, okwesibili - ukunyakaza kuyafana ukuthi imicibisholo on iwashi. Kodwa isici ukuthi ukucindezeleka ngamunye polar - into kumuntu, okungukuthi, kukhona imodeli ephelele yengxoxo, elikwaziyo ukuyichazela.

Isibikezelo sezulu sezinsuku kungenzeka

Okunakekela sezulu ayimigodi engaphelele ingase ibe ngombandela wokuthi indawo enkulu imbozwe kokuma anokulandisa okufanayo. Ngokwesibonelo, i-European endaweni yocwaningo izwekazi kufanele ukwandisa kuya entshonalanga, kuhlanganise eduze endaweni Atlantic. Ngoba izimiso zemvelo ngokuvamile ezifana abe ijubane 1000 km ngosuku. Uma kokuma abazenzi phezulu izingqimba ebangelwa umkhathi, kuyoba kakhulu lula umsebenzi ku isimo emkhakheni, lapho kukhona isishingishane.

Izimo zethu zihluke kakhulu ezivamile lapho phambi ukucindezeleka coalesce emkhayeni emikhulu, ezihilela kumiswa ngokunyakaza yesibili emhlabeni ukugeleza main. Okuvame kakhulu yilezo avele emaphethelweni emoyeni abandayo. Njalo omele esilandelayo uphawu enjalo lomkhaya indlela eduze nenkabazwe kuneyokuqala.
