Amawaka aphindwe kabini ukuba ayizisigidi uyaliva igama kwimozulu isaqhwithi. Banxulunyaniswa nemozulu embi kunye nemvula, kodwa ngekhe ungazi kakuhle ukuba yintoni kwaye yenziwe njani. Isaqhwithi sisimo sezulu esimalunga ne Uxinzelelo lomoya Kwaye, ke, kuya kufuneka uyazi kancinci malunga nokusebenza kwayo ukuze wazi ukuba yintoni.
Kule nqaku siza kukubonisa ukuba yintoni isiqhwithi, ukuba senziwa njani kunye neentlobo ezahlukeneyo zesaqhwithi ezikhoyo.
Yintoni isiqhwithi
Into yokuqala kukwazi ukuba le meko yemozulu imalunga nantoni. Izinto ezinxulunyaniswa noxinzelelo zezo zikwimo yokuba kunomoya ngakumbi okanye kuyanetha, kuyabanda okanye kushushu. Xa sidibana nemeko yoxinzelelo oluphezulu, kuthiwa kukho i-anticyclone. Ii-anticyclone zihlala zihambelana nemozulu elungileyo kunye nemozulu elungileyo. Kuhlala kukho umoya omncinci kwaye kuhlala ilanga.
Kwelinye icala, xa uxinzelelo luphantsi, luhlala luhamba nenkanyamba okanye isaqhwithi. Inyaniso yokuba uxinzelelo lweatmosferi lusezantsi kuthetha ukuba kuloo ndawo inexabiso elingaphantsi kwawo wonke umoya ojikelezileyo. Iimozulu ziqokelela idatha yokufunda i-barometer kwizikhululo zemozulu ezahlukeneyo kwihlabathi liphela. Ngale datha, iimephu zinokwenziwa apho iinxalenye ezinexinzelelo oluninzi okanye ngaphantsi zibonisiwe.
Izaqhwithi zenzeka kwiindawo ezinobushushu obuphakathi. Zenziwe ngokuhamba ngapha nangapha kwimimandla emibini yomoya oshushu nobandayo. Iimpawu zabo zahlukile xa ezi moya zidibana. Ukuphuhliswa kwenkqubo yoxinzelelo oluphantsi esiyibiza ngokuba sisaqhwithi yahlulwe yangamacandelo amane: kwangoko, ukuvuthwa, ukonakala, kunye nokuchithwa. Ngokwesiqhelo, xa kukho isaqhwithi, siyakwazi ukuhlala ngokomndilili malunga neentsuku ezisixhenxe.
Esi sizathu sokuba xa kufika imozulu embi kwaye kusithiwa "isaqhwithi siyeza", uqikelelo lwenziwa kwiveki yonke. Iziphumo ziya kuqala ukuqaphela kancinci kancinci, ziya kufikelela kwi-zenith yayo phakathi evekini kwaye iya kugqiba ukunciphisa iziphumo zayo ide inyamalale ngokupheleleyo.
Iimpawu eziphambili
Umda woxinzelelo oluphantsi ujikelezwe yimimoya ehamba ngokungqinelana newotshi kumantla e-hemisphere nakwiwotshi kumazantsi e-hemisphere. Zombini iinkqwithela neenkanyamba ziveliswa sisaqhwithi oko kuphelela ekubeni nobukhulu obukhulu kunye neziphumo.
Njengoko besesitshilo ngaphambili, isaqhwithi yintsingiselo yemozulu embi. Xa isiphepho sibhengezwa kwiindaba zikamabonakude, kulindeleke ukuba kubekho ubuncinci iveki enemozulu embi apho siza kuba nemvula, imimoya kunye nemozulu embi ngokubanzi. Phakathi kweempawu zayo sifumana ukugcwala okuphezulu. Kungenxa yokuba, xa umoya unyuka, uyaphola, ujiye kwaye unike indawo yokufuma. Iziphumo ezikhawulezileyo yimvula enzima kunye nokuvuthuza komoya kunye izaqhwithi zombane.
Nangona abantu bengazi ngokupheleleyo, zininzi iinkqwithela ezinokuveliswa bubushushu obugqithisileyo. Ukusekwa kwezi nkqwithela kunxulunyaniswa nemida ye-Atlantic.
Yenziwa njani
Siza kuhlalutya inyathelo ngenyathelo ekufuneka kwenzekile emoyeni ukuze kubekho isaqhwithi. Ihlala iqala xa ubunzima bomoya obandayo nobomileyo obuvela ngaphambili buhamba emazantsi. Kwangelo xesha linye oku kuyenzeka, umoya oshushu, oqhele ukufudumala kwaye ufumile, usinga emantla. Esi ibisisigaba sokuqala apho uqhwithela luqala ukubakho.
Isigaba esilandelayo kukudlathuka okukhoyo xa kudibana izihlwele zomoya. Le ripple iyaqina kakhulu kwaye iintloko zomoya osemazantsi zihamba emazantsi. Zombini iziqu zomoya ziphethe umphambili, kodwa eya emazantsi ithwala umphambili obandayo kwaye leyo iya emantla iphethe eshushu.
Kungenxa yezi meko apho eyona mvula inamandla ivela kwindawo ebandayo. Inqanaba lokugqibela lokwakheka kwesiphepho kulapho umphambili obandayo uwugibe ngokupheleleyo lo ushushu, uwenze ube mncinci. Ukongeza, ikwahlulahlula kubunye bomoya obushushu kwaye ishenxisa konke ukufuma obekuzisile. Ngokususa ukufuma, isebenza kumandla akho.
Kungalo mzuzu apho iifom zangaphambili ezifihliweyo kunye nalapho kukho inkqwithela yomoya. Esi saqhwithi siza kufa njengoko umphambili we-polar uzinzileyo. Inqanaba lokugqibela lesiphango liphela ngokufanayo iintlobo zamafu ukuvela ngaphambili kushushu.
Iindidi zesquall
Kukho iintlobo ezininzi zeziphepho ezaziwa njenge:
- Thermals. Zizo ezo ukunyuka komoya kwenzeka xa amaqondo obushushu ephezulu kakhulu kunalawo okusingqongileyo. Ke iyenzeka ngenxa yobushushu obugqithisileyo njengoko ikhula. Eyona nto iqhelekileyo, inqanaba lonyukelo lonyuka ngamandla, lulandelwe kukuncipha. Ngenxa yolu hlobo lweenkqwithela, kubakho imvula eninzi kakhulu.
- Amandla Olu hlobo lwesaqhwithi luvela ekunyukeni komoya ukuya kwindawo ye-tropopause (ikhonkco). Le ntshukumo ibangelwa luxinzelelo lwenqwaba yomoya obandayo kwaye ihambile. Izaqhwithi zolu hlobo zihlelwa njenge-subpolar phenomena kwaye zii-barometric depressions phakathi kweendawo eziphakamileyo zoxinzelelo. Ubume bayo bomzobo benziwe njengentlambo.
Phakathi kweziphumo zezaqhwithi esinazo Imimoya efikelela kwiikhilomitha ezili-120 ngeyure. Ibangela ukuqhekeka komhlaba ezindleleni kwaye yenza iindlela zonxibelelwano zibenzima ngemimoya enamandla kunye nemvula. Isibhakabhaka sinamafu amaninzi kwaye, eyona nto iqhelekileyo kukuba isaqhwithi sikhatshwa ngamathontsi obushushu.
Ndiyathemba ukuba ngolu lwazi ungazi ukuba yintoni isivunguvungu kwaye senziwa njani ukuze ungashiywa ungazi nto xa ufunda iindaba zemozulu.
