Impela wake wabona a imvula yodaka. Kubizwa kanjalo lapho amadolobha embozwe ungqimba lwangaphandle lodaka nesihlabathi ngemuva kwemvula. Ngokuvamile, lina endaweni lapho umoya nomhlabathi kuhlanzwa futhi kuhlanzwe khona. Kodwa-ke, phakathi nalezi zimvula yonke into ibingcolile kunakuqala. Futhi ngukuthi lezi zenzakalo zaziwa kakhulu ngokushiya izimoto zigcwele udaka.
Ungathanda ukwazi ukuthi kungani izihlambi zodaka zenzeka nokuthi zivame ukwenzeka nini?
Kungani Izimvula Zodaka Zenzeka
Lezi zimvula zivame kakhulu entwasahlobo nasehlobo. Kodwa-ke, yisimo sezulu esingenzeka nganoma yisiphi isikhathi sonyaka. Kuyinto ecishe ihluke eSpain ngenxa yesikhundla sayo. Isizathu esenza zenzeke silele othulini lwase-Afrika. Ugwadule iSahara luseduze neNhlonhlo Yase-Iberia. Lokhu kudala ukuthi imimoya enamandla isuse lonke loluthuli ezweni lethu.
Lapho uthuli olusemoyeni esibhakabhakeni lusebenza njenge-hygroscopic condensation nuclei, kuba nomthelela ekwakhiweni kwamafu emvula. Kuhambisana nokungazinzi komkhathi nomoya oshintshayo, ifomula yalezi zimvula zodaka iyaqedwa. Lapho lezi zimvula zenzeka, isibhakabhaka nezimoto kudaywa ngemibala enodaka nodaka.
Babizwa nangokuthi "izihlambi zegazi" kwezinye izindawo. Lokhu kungenxa yokuthi ngenkathi efudumele, udaka olunamanzi lungathola umbala omncane obomvu. Ngalezi ziqephu zemvula kukhulunywa kakhulu ngeSahara nomphumela wayo kuzinga lomoya laseSpain.
Futhi ugwadule luhlala njalo singenisa uthuli emoyeni wethu. Ngokuya ngombuso womoya nokuqina kwawo, inani lothuli olungena eSpain cishe lincane.
Ukuhlaziywa kwemvula
Lezi zimvula ngokuvamile zibikezelwa ngenxa yezithombe zesathelayithi. Ngemifanekiso etholwe kusathelayithi, ungabona ukuvunguza kokudangala kuhudula ifu lothuli. Lapho umfutho womoya uncipha endaweni, umoya uzozungeza leyo ndawo ephansi yengcindezi. Kungaleso sikhathi-ke lapho, ngokuya ngesikhala sendawo esikuso, lapho kuthiwa umoya uzohamba uyisiyingi phezu kwendawo yengcindezi ephansi ngendlela eya ngaswashi noma ngakuwashi.
Imvula yodaka akudingeki ukuthi kube kanye kuphelakepha ingahlala izinsuku. Konke lokhu kuncike ezimeni zemimoya nasekuqondeni. Uma ukungazinzi komkhathi okwakhiwa amafu emvula kuqhubeka izinsuku ezimbalwa futhi umoya uletha uthuli oluningi lwaseSahara ngawo, imvula eyenzekayo iyoba nodaka.
Imvamisa, izindawo ezithinteka kakhulu yimvula yodaka ase-Andalusia. Lokhu kungenxa yokusondela kwezwekazi lase-Afrika. Zingabonakala nasezindaweni eziphakathi nendawo ngisho nasenyakatho yeSpain, kepha ngokuvama okuncane nokuqina. Uma ibanga likhona, mancane amathuba okuthi kwenzeke.
Imiphumela emibi
Imiphumela yeshawa lodaka ibonakala ngokusobala enyangeni yemoto. Ngemuva kwesiqephu salezi, ungabona ukuthi izimoto ezidayiwe nsundu zivela kanjani. Kubukeka sengathi sebedlulile ixhaphozi lodaka.
Le nto ayikho ezimotweni kuphela, kepha futhi iyabonakala nasemigwaqeni yezindlela ngisho nasemacembe ezihlahla. Uma ubheka isibhakabhaka ngalezo zinsuku, uyabona ukuthi ithoni yamafu ayimhlophe, kepha kunalokho iguquka.
Omunye wemiphumela lezi zimvula ezinayo lapho zenzeka ehlobo ukwenyuka kwezinga lokushisa. Lokhu kungenxa yokuthi umoya olethwa uthuli lwaseSahara ufudumele kunalowo osenhlonhlweni.
Kuhlala isikhathi esingakanani?
Le nto ingenzeka nganoma yisiphi isikhathi sonyaka. Kodwa-ke, kuvame kakhulu ezinyangeni zasehlobo nasentwasahlobo. Imvamisa ukumiswa kothuli emkhathini ingahlala phakathi kwamahora angama-24 kuya kwangu-60. Ngemuva kwalokho, iqala ukunyamalala.
Kufanele ugcine engqondweni ukuthi Ama-70% alo lonke uthuli emhlabeni wonke avela ehlane laseSahara. Lolu ucezu lolwazi olubaluleke kakhulu okufanele ulunakekele ukuze wazi umthelela walo kuzinto eziphilayo zomhlaba wonke.
Lolu daka alugcini nje ngokungcolisa imigwaqo nezimoto zethu, kodwa futhi lunikela ngomsoco emhlabeni nasolwandle. Amaminerali amisiwe, amabhaktheriya, izinhlamvu kanye nempova kuhamba eceleni kothuli nesihlabathi esingaphansi kweSahara. Sekukonke, bayakwazi ukunqoba amabanga amade ukufinyelela ezindaweni ezingalindelekile. Njengesibonelo, ngaphansi kukasofa wakho noma ngaphakathi kwezwekazi laseYurophu izinkulungwane zamakhilomitha kude.
Ngiyethemba ukuthi manje ukwazile ukuthi kungani lezi zinto zenzeka 🙂
