Impela uzwile ngoJehova isivunguvungu selanga kokubili kumabhayisikobho nakwabezindaba. Luhlobo lwesimo esingathinta kakhulu iplanethi yethu uma kwenzeka. Ukungabaza okukhulu ukuthi lolu hlobo lomkhuba ludala ukuthi ngabe uMhlaba usengozini yokuhlaselwa yilesi siphepho selanga.
Ngakho-ke, sizonikezela le ndatshana ukukutshela ukuthi siyini isiphepho selanga nokuthi singaba namiphi imiphumela emhlabeni wethu.
Izici eziyinhloko
Isiphepho selanga yinto eyenzeka ngenxa yokusebenza kwelanga. Ilanga nomsebenzi walo kuphazamisa amandla kazibuthe womhlaba yize inkanyezi ikude kakhulu neplanethi yethu. Kunabantu abaningi abakholelwa ukuthi izivunguvungu zelanga azikwazi ukudala umonakalo wangempela, yize kukhonjisiwe kwezinye izikhathi ukuthi zingakwazi. Lezi zimo zenzeka njengomphumela kwama-solar flare kanye nama-coronal mass ejection. Lokhu kuqhuma kubanga umoya welanga kanye nokuqhuma kwezinhlayiya eziya ohlangothini lweplanethi yethu.
Uma isingene kumandla kazibuthe womhlaba, isiphepho se-geomagnetic singenziwa esingahlala izinsuku ezimbalwa. Ngaphakathi kwesiphepho selanga sinemisebenzi kazibuthe ebusweni belanga futhi lokho kungadala amabala elanga. Uma lezi zingqimba zelanga zinkulu zingadala amalangabi elanga. Yonke le misebenzi ivame ukugcwala i-asthma evela elangeni. Lapho kukhishwa le-plasma, kwenzeka into yesibili eyaziwa ngokuthi yi-coronal mass ejection.
Ngenxa yebanga eliphakathi koMhlaba nelanga, ngokuvamile kuthatha cishe izinsuku ezintathu ukuthi izinhlayiya zifike. Lesi ngesinye sezizathu zokuthi kungani ubona i Izibani ZaseNyakatho. Ilanga linemijikelezo yeminyaka eyi-11 futhi ososayensi bakholelwa ukuthi isiqongo lapho benomsebenzi omkhulu welanga kwakungu-2013. Esinye sezivunguvungu zelanga esibi kakhulu kwirekhodi senzeka ngo-1859 futhi siyaziwa ngenxa yomcimbi waseCarrington. Lesi siphepho selanga sabangela izinkinga ezinkulu ze-electromagnetic kuyo yonke iplanethi. Amalambu aseNyakatho angabonakala ezindaweni lapho kungenakubalwa khona ngokujwayelekile. Kwaphakama nezinkinga ezinkulu kumadivayisi kagesi.
Ezinye izivunguvungu ezinamandla zelanga zenzeka ngeminyaka yo-1958, 1989, kanye no-2000. Lesi siphepho saba nemiphumela embalwa kepha kwaba khona ukucima kukagesi kanye nomonakalo kuma-satellite.
Izingozi zesiphepho selanga
Uma le nto inkulu, ingaphazamisa ugesi emhlabeni. Omunye wemiphumela emibi kakhulu ongaba nawo ukuthi uzosula ugesi emhlabeni jikelele. Kungadingeka ukuguqula yonke intambo ukuze ikwazi ukukhanyisa futhi. Iphinde ithinte kakhulu ukuxhumana neziphuphutheki. Ngeke siphike ukuthi abantu bathembele kakhulu kuma-satellite. Namuhla sisebenzisa iziphuphutheki kukho konke. Kodwa-ke, isivunguvungu selanga singabhubhisa noma senze ama-satellite ayeke ukusebenza.
Kungathinta futhi osomkhathi abasesikhaleni ngezifundo ezahlukahlukene. Isiphepho selanga singakhipha imithamo emikhulu yemisebe. Imisebe iyingozi empilweni yethu. Kungadala umdlavuza nezinkinga ezizukulwaneni ezizayo. Inkinga ngemisebe ukuvezwa kwayo nenani. Konke ngezinga elikhulu noma elincane kuvezwe inani elithile lemisebe ngenxa yemishini nezinto zikagesi. Kodwa-ke, noma ngubani othathe isikhathi eside ukuthola imisebe ephezulu, maningi amathuba okuthi avele kwezinye zalezi zifo.
Izilwane eziningi ziyaluzwa ushintsho kumandla kazibuthe womhlaba, ngakho isiphepho selanga singadala ukuthi ziphazamiseke. Izilwane ezinjengezinyoni eziholwa amandla kazibuthe womhlaba ukwenza ukufuduka kwazo, bangadideka futhi bafe, bebeka engcupheni ukusinda kwezinhlobo.
Enye ingozi yale nto ukuthi ingashiya izizwe zonke zingenawo ugesi izinyanga. Lokhu kungadala umonakalo omkhulu emnothweni wamazwe futhi kungathatha iminyaka ukubuyela endaweni efanayo nanamuhla. Sincike kakhulu kubuchwepheshe kangangokuthi umnotho wethu wonke uzungeze bona.
Kuthiwani uma isivunguvungu esikhulu selanga senzeka namuhla?
Njengoba sesibonile ukuthi izivunguvungu zelanga ziyakwazi ukuphazamisa ukuxhumana nokuxhumana kwamandla futhi zidale ukunqanyulwa kukagesi, kungashiwo ukuthi namhlanje sibe nesiphepho esifana nalesi esenzeka ngo-1859, impilo izokhubazeka ngokuthi kugcwele. Ngesikhathi sesiphepho saseCarrington, amalambu asenyakatho aqoshwa eCuba naseHonolulu, kuyilapho ama-auraora aseningizimu abonakala eSantiago de Chile.
Kuthiwa ukukhanya kokuntwela kokusa bekukukhulu kangangoba leli phephandaba belingafundwa kuphela ngokukhanya kokusa. Yize imibiko eminingi yesiphepho saseCarrington isalokhu iyizintshisekelo nje kuphela, uma kungenzeka into efana nalena yenzeke namuhla, ingqalasizinda yobuchwepheshe obuphezulu ingakhubazeka. Njengoba sishilo phambilini, umuntu usencike ngokuphelele kubuchwepheshe. Umnotho wethu ubophezeleke kakhulu kuwo. Uma ubuchwepheshe buyeka ukusebenza, umnotho uyama.
Abanye ochwepheshe bathi ukuphazamiseka kukagesi okuqine njengaleyo eyalimaza imishini yocingo (eyayaziwa njenge-internet ngaleso sikhathi) manje kuzoba yingozi kakhulu. Iziphepho zelanga zinezigaba ezintathu, yize kungezona zonke okumele zenzeke esivunguvungwini. Into yokuqala ukuthi kuvela amalanga elanga. Yilapho i-X-ray nokukhanya kwe-ultraviolet kukhanyisa ungqimba olungaphezulu lomkhathi. Yile ndlela ukuphazamiseka kwenzeka ngayo ekuxhumaneni nomsakazo.
Kamuva kufika isiphepho semisebe futhi kungaba yingozi kakhulu kosomkhathi emkhathini. Ekugcineni, isigaba sesithathu yileso lapho kunokukhetha khona ubukhulu be-coronal, ifu lezinhlayiya ezikhokhisiwe ezingathatha izinsuku ukufinyelela emkhathini womhlaba. Lapho ifinyelela emkhathini, zonke izinhlayiya ezivela elangeni ziyahlangana namandla kazibuthe womhlaba. Lokhu kudala ukuguquguquka okunamandla kagesi. Kunokukhathazeka ngemiphumela ebingaba nayo kwi-GPS, kumafoni akhona manje, ezindizeni nasezimotweni.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngesiphepho selanga.
