Ngokuqinisekileyo wakha wangqina a imvula yodaka. Kubizwa njalo xa izixeko zigutyungelwe ngodaka nesanti emva kwemvula. Ngokubanzi, kwindawo enethayo kuyathetha ukuba umoya kunye nomhlaba ziyahlanjululwa kwaye zicocwe. Nangona kunjalo, ngelixesha lemvula yonke into ibumdaka kunangaphambili. Kwaye ezi zinto ziyaziwa ngokushiya iimoto zigcwele udaka.
Ngaba ungathanda ukwazi ukuba kutheni kusenzeka imvula yodaka kwaye zihlala zisenzeka nini?
Kutheni le nto iimvula zodaka zenzeka
Le mvula ixhaphake kakhulu entwasahlobo nasehlotyeni. Nangona kunjalo, yimeko yemozulu enokwenzeka nangaliphi na ixesha lonyaka. Yinto ephantse yahluka eSpain ngenxa yokuma kwayo. Isizathu sokuba zenzeke zilele kuthuli lwaseAfrika. Intlango yeSahara isondele kufutshane neIberia Peninsula. Oku kubangela ukuba imimoya enamandla isuse lonke uthuli kwilizwe lethu.
Xa uthuli oluqhutywa ngumoya esibhakabhakeni lusebenza njenge-hygroscopic condensation nuclei, inegalelo ekwakhiweni kwamafu emvula. Ikhatshwa kukungazinzi kwemozulu kunye nomoya oguqukayo, ifomula yezi mvula zodaka igqityiwe. Xa le mvula isenzeka, isibhakabhaka kunye neemoto zidaywe ngemibala enodaka nodaka.
Kukwabizwa ngokuba "ziishawa zegazi" kwezinye iindawo. Kungenxa yokuba ngexesha elifudumeleyo, udaka oluthambileyo lunokufumana umbala omncinci obomvu. Ngethuba lezi ziqendu zemvula kukho intetho eninzi malunga neSahara kunye nefuthe layo kumgangatho womoya waseSpain.
Kwaye intlango ihlala ihleli ukwazisa uthuli emoyeni wethu. Kuxhomekeke kulawulo lomoya kunye nokuqina kwayo, inani lothuli olungena eSpain lungaphezulu okanye ngaphantsi.
Uhlalutyo lwemvula
Le mvula iqikelelwa ngenxa yemifanekiso yesathelayithi. Ngemifanekiso efunyenwe kwisathelayithi, ungabona ukudakumba koxinzelelo kutsala ilifu lothuli. Xa uxinzelelo lweatmosfera luyehla endaweni, umoya uya kujikeleza loo mmandla woxinzelelo oluphantsi. Kulapho ke ngoku, ngokuxhomekeke kumhlaba apho sikhona, laa moya uthe uya kuhamba ngesangqa ngaphezulu kommandla woxinzelelo olusezantsi ngendlela ejonge kwewotshi.
Imvula enodaka akufuneki ibelixesha elinyekodwa inokuhlala iintsuku. Konke oku kuxhomekeke kwimeko kwimimoya nakwicala. Ukuba ukungazinzi komoya okwenziwa ngamafu emvula kuyaqhubeka kangangeentsuku ezininzi kwaye umoya uzisa uthuli oluninzi lwaseSahara ngawo, imvula eyenzekayo iya kuba ludaka.
Ngokwesiqhelo, ezona ndawo zichaphazeleka kakhulu yimvula yodaka ziseAndalusia. Oku kungenxa yokusondela kwilizwekazi laseAfrika. Banokubonwa nakwiindawo eziphakathi kwaye nakumantla eSpain, kodwa ngokuhamba kancinci kunye nokuqina. Umgama ongaphezulu okhoyo, kokukhona kuya kwenzeka okuncinci.
Iziphumo ezibi
Iziphumo zeshawa lodaka zibonwa ngokucacileyo kwinyanga yemoto. Emva kwesiqendu salezi, uyayibona indlela iimoto ezidayiweyo ezimdaka ezibonakala ngayo. Kubonakala ngathi badlulile umgxobhozo wodaka.
Into ayikho kwiimoto kuphela, kodwa inokubonwa kwiindledlana nakwiindlela zamagqabi emithi. Ukuba ujonga isibhakabhaka ngezo ntsuku, uyabona ukuba ithoni yamafu ayimhlophe, koko ijike ibe ngamafu.
Esinye seziphumo ezinazo le mvula xa zisenzeka ehlotyeni kukonyuka kweqondo lobushushu. Oku kungenxa yokuba umoya oziswa luthuli lwaseSahara ushushu kunalowo usingasiqithi.
Lihlala ixesha elingakanani?
Le nto inokwenzeka nangaliphi na ixesha enyakeni. Nangona kunjalo, ixhaphake kakhulu kwiinyanga zasehlotyeni nasentwasahlobo. Ngokwesiqhelo ukumiswa kothuli emoyeni inokuhlala phakathi kweeyure ezingama-24 nama-60. Emva koko, iqala ukunyamalala.
Kuya kufuneka uhlale uyikhumbula loo nto I-70% yothuli lonke ivela entlango yaseSahara. Eli licandelo lolwazi olubaluleke kakhulu ekufuneka ulithathele ingqalelo ukuze wazi ifuthe lalo kwindalo iplanethi yonke.
Olu daka alugcini nje ngokungcolisa izitalato neemoto zethu, kodwa lukwa negalelo kwizondlo emhlabeni nakwiilwandlekazi. Amaminerali amisiweyo, iibhaktiriya, ii-spores kunye ne-pollen zihamba ecaleni kothuli kunye nentlabathi ese-Sahara Ngokubanzi, bayakwazi ukoyisa imigama emide ukuya kwezona ndawo zingalindelekanga. Njengaye, umzekelo, phantsi kwesofa yakho okanye ngaphakathi kwilizwekazi laseYurophu amawaka eekhilomitha kude.
Ndiyathemba ukuba ngoku ukwazile ukuba kutheni le nto isenzeka?
