Sibone kuyo yonke le bhulogi izinhlobo eziningi zesimo sezulu kusukela kwezivamile kuya kwezingajwayelekile. Kulokhu sizokhuluma nge i-nortada. Kuyinqwaba yomoya ovela e-arctic owehlisa amazinga okushisa kakhulu. Lokhu kubangela ukuthi amazinga eqhwa aqale ukwehla futhi kubangele imvula enkulu eneqhwa.
Kulesi sihloko sizokutshela ukuthi iyini i-nortada, yiziphi izici zayo, umsuka kanye nemiphumela engenzeka.
yini i-nortada
Ngalo nyaka ikhalenda lasitshela ngenyanga ka-April ukuthi intwasahlobo iyeza. Noma kunjalo, amazinga okushisa ayephansi ngokuphawulekayo kuya kubanda ngendlela engavamile ngaleyo nyanga. Ubukhona be-nortada. Njengoba iSonto Elingcwele lalifika, kwakubonakala sengathi ubusika buyabuya.
I-nortada isenzakalo sesimo sezulu esinomsuka wayo ubusika obupholile obusenyakatho obuvunguza ngokuqhubekayo isikhashana. Kuyinto yesimo sezulu esivame ukudideka namagagasi abandayo. Nokho akufani.
Isibikezelo sezimo zezulu zezinsuku zenyanga ka-April nokwehla kwezinga lokushisa akubangelwanga amagagasi abandayo. Ukukhuluma ngegagasi elibandayo, kufanele kube nokwehla okungenani okungu-6ºC emahoreni angama-24, okuthinta okungenani u-10% wendawo izinsuku ezintathu noma ngaphezulu. Izazi zezulu zikhomba amazinga okushisa aphansi kakhulu okufanele aqoshwe ezingxenyeni ezihlukene zaseSpain ukuze abhekwe njengegagasi elibandayo:
- Ogwini lwe-peninsular, i-Balearic Islands, i-Ceuta ne-Melilla: izinga lokushisa elincane kufanele lifinyelele embundwini ongu-0ºC.
- Ezindaweni lapho ukuphakama kuphakathi kwezinga lolwandle kanye namamitha angu-200: izinga lokushisa elincane kufanele lifinyelele embundwini ophakathi kuka-0 no -5ºC.
- Ezindaweni eziphakathi kwamamitha angu-200 no-300 ngaphezu kwezinga lolwandle: izinga lokushisa elincane kufanele lifinyelele embundwini ophakathi kuka -5 no -10ºC.
- Ezindaweni eziphakathi kwamamitha angu-800 no-1.200 ngaphezu kwezinga lolwandle: izinga lokushisa elincane kufanele lifinyelele embundwini ongaphansi kuka -10ºC.
i-arctic air mass eneqhwa
I-nortada yathatha izinyathelo zayo zokuqala ngoLwesine, Mashi 31, ngezinga lokushisa elipholile kanye nemvula enyakatho yeSpain njengoba umoya womoya wase-Arctic uqhubeka. Amazinga okushisa ehle kakhulu engxenyeni yesithathu esenyakatho-mpumalanga yenhlonhlo kusukela ngoLwesihlanu, Ephreli 1, njengoba umoya obanda kakhulu obuqhutshwa yisiphepho saseYurophu uhambela eningizimu-mpumalanga, ngokusho kwezibikezelo ze-Aemet. Ngaphezu kwalokho, imimoya enamandla yasenyakatho-ntshonalanga eyayihambisana nokwehla okukhulunywe ngakho ngenhla yandisa ukushisa nokubanda engxenyeni yesithathu esenyakatho-mpumalanga yenhlonhlo nasenyakatho yesifunda saseMedithera.
Amazinga okushisa phakathi kuka-April 1 no-4 abephansi ngokungavamile entwasahlobo njengoba u-April engavamile ngoba iqhwa alivamile ukuwa enyakatho ngokwedlulele yale nhlonhlo.
Impelasonto ebandayo yayifanele ubusika obunzima kakhulu, nesithwathwa esisakazeke engxenyeni esenyakatho nangaphakathi kwe-peninsular southeast. Iqhwa laqhubeka nokuwa kulezo zindawo ngoMgqibelo, nakuba lalinamandla amancane. Ukuntengantenga kwesimo kwenze kwaba nzima ukwenza izibikezelo ezinembayo zesonto elizayo.
amazinga okushisa e-nordic
AbeNational Meteorological Service (Aemet) baxwayise ngokuthi amazinga okushisa azokwehla cishe ngo-15 ºC futhi azoba ngaphansi kwesijwayelekile kanye nesithwathwa esinamandla. Ikakhulukazi ekuseni, ukuphuma kwelanga kwakusebusika.
Ukuwa kweqhwa kwehle kakhulu. Amazinga eqhwa ayengaphansi kwamamitha angu-600, noma ngisho namamitha angu-400. E-Penibético, iqhwa lawela kumamitha angu-900. Kwakukhona nezikhithi ezinkulu empumalanga yeCantabrian Sea nasePyrenees, elineqhwa elingaba amasentimitha angu-50 noma ngaphezulu ngamahora ambalwa. EFrance naseningizimu yeJalimane, kwawa iqhwa kwamanye amadolobha endaweni ephakeme kakhulu.
Umehluko ngama-cold snaps
Igagasi elibandayo liyisenzakalo lapho izinga lokushisa lehla kakhulu ngenxa yokungena kwenani elikhulu lomoya obandayo. Lesi simo sithatha isikhathi esingaphezu kosuku futhi singadlulela emakhulwini noma ezinkulungwaneni zamakhilomitha-skwele.
Izinhlobo ezimbili ziyahlukaniswa:
- izixuku zomoya we-polars (amagagasi asezindaweni ezishisayo noma amagagasi okubanda endaweni eshisayo): Akha phakathi kwama-55 nama-70 degrees ngaphezu kwezinga lolwandle. Kuye ngokuthi baya kuphi, badlula kwezinye izinguquko noma ezinye. Isibonelo, uma ziya ezindaweni ezifudumele, ziyashisa futhi zingazinzi enqubweni, okungavuna ukwakheka kwamafu emvula anjengesiphepho; esikhundleni salokho, uma beya ngase-Atlantic nasePacific, umoya uyobe ugcwele umswakama, futhi lapho uhlangana namanzi ahlanzekile, kuzokwakheka inkungu noma ifu elibuthakathaka lemvula.
- Izindimbane zomoya zase-Arctic ne-Antarctic noma zaseSiberia: Isuka ezindaweni eziseduze nezigxobo. Zibonakala ngokushisa kwazo okuphansi, ukuzinza okuphezulu kanye nomswakama ophansi, okungakhiqizi i-turbidity. Ngokuvamile azikhiqizi iqhwa eliningi ngaphandle uma zidlula olwandle i-Atlantic Ocean, njengoba ukwenza kanjalo kuzozenza zingazinzi.
Ukuze ugweme izinkinga, kubaluleke kakhulu ukugqoka izingubo ezifudumele ukuze uzivikele emakhazeni, uma kungenzeka, amabhulukwe anele, ama-sweaters namabhantshi, esikhundleni sezingubo eziningi, ezingase zingakhululekia. Ngokunjalo, kubalulekile ukuvikela intamo nezandla, kungenjalo singangenwa umkhuhlane ngesikhathi esifushane kunalokho esikucabangayo. Uma sigula, kufanele sibonane nodokotela futhi sigweme ukuphuma size sibe ngcono. Uma kufanele ushayele, kufanele uhlole isibikezelo sezulu futhi uqaphele amaketanga angasetshenziswa, ikakhulukazi uma kufanele udlule noma uye ezindaweni ezineqhwa.
Igagasi elide kunawo wonke labhalwa ebusika 2001-2002, nezinsuku eziyi-17, nakuba ngawo-80, ikakhulukazi ngo-1980-1981, bekunezinsuku ezingama-31 zamagagasi, nakuba zihlukaniswe iziqephu ezine. Uma sibheka izindawo ezithintekile, izifundazwe ezikhahlamezeke kakhulu amakhaza ubusika bango-1984 no-1985, ezinezifundazwe ezingu-45 sezizonke, uma kuqhathaniswa nezifundazwe ezingu-44 ezakhahlanyezwa amakhaza ango-1982-1983 eminyakeni embalwa edlule.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi iyini i-norteda nokuthi ihluke kanjani ezithombeni ezibandayo.
