Kuxhomekeka kwiimeko zemozulu ezikhoyo kumzuzu ngamnye, asinakusoloko sifumana olona hlobo lwemvula. Oko kukuthi, ayinakuhlala imvula, ikhephu okanye isichotho, kodwa kukwakhona imvula. Yinto yendalo apho kukho imvula kwimo yemvula kwaye nieve. Ukuze le nto yenzeke, kufuneka kuhlangatyezwane neemeko ezithile zemo engqongileyo kunye neyobume bomhlaba. Ukongeza, olu hlobo lweziganeko zemozulu lukwabangela ukungqinelana okunje nge-sleet.
Siza kukucacisa konke oku malunga ne-sleet kunye ne-sleet kule post.
Yintoni i-sleet kwaye yenzeka nini?
Kukho amaxesha apho iimeko zokusingqongileyo ziyahluka. Njengoko sisazi, iimeko ezahlukeneyo zemozulu zezi zezo zilawula iimeko zokusingqongileyo ngamaxesha onke. Kuxhomekeka kumaxabiso Uxinzelelo lomoya, ubushushu, ulawulo lomoya, amafu, umswakamanjl. Kunokubakho uhlobo olunye lwemvula okanye olunye. Eyona nto ixhaphakileyo kukuba ukuba amaqondo obushushu angaphezulu kwe-0 degrees kwaye ukufuma kuphezulu, imvula yenzeka ngendlela yemvula.
Kwelinye icala, ukuba amaqondo obushushu asezantsi kune-0 degrees okanye sikwindawo ephezulu, apho uxinzelelo lusezantsi, kuhlala rhoqo okanye kunokwenzeka ukuba imvula yenzeke ngendlela yekhephu. Nangona kunjalo, ezi meko zemo yendalo esingqongileyo azinyanzelekanga ukuba zibe "ngutata wethu" wemeteorology, kodwa kukho izinto ezifana nesleet.
Sleet luhlobo lwemvula apho imvula nekhephu zenzeka ngaxeshanye. Icandelo lemvula linomkhenkce kwaye ezinye iifom zamanzi amachaphaza okanye iikristal ezincinci zomkhenkce. Ukuze amanzi ekhephu aveliswe kufuneka kubekho imeko echanekileyo yokusingqongileyo. Kwaye kwenzeka kuphela xa umoya ushushu ngokwaneleyo ukuba uqalise ukunyibilikisa ikhephu, kodwa ngaphandle kokunyibilika ngokupheleleyo. Olu hlobo lomoya luxhomekeke kubude, ukufuma kunye nolawulo lomoya. I-Sleet ayinakuhlala isenzeka nokuba ubushushu bomoya bulungile ukuze amanzi aqale ukunyibilika kodwa anganyibiliki ngokupheleleyo.
Amakristali e-Ice abizwa ngokuba ziiflakes anobume obunamacala amathandathu xa ujongwa kufutshane.
Iimpawu zeSleet
I-Sleet ayiqheleki ukuba lukhuni emhlabeni, kodwa iqala ukubonakala njengoko isihla ivela emafini. Ngokwesiqhelo, ukuba amaqondo obushushu angaphantsi kwezinga le-zero, iflake ngokwayo inokuba lukhuni kwaye yenze ikristale yomkhenkce yakuba iwele ngaphezulu. Kwelinye icala, Ingqele yala maqhekeza emhlabeni inokwenza oko sikwaziyo njengamashiti womkhenkce okanye iqabaka.
Kwezinye iimeteorologists, i-sleet luhlobo lwemvula apho amanzi enqabile, kodwa akufuneki ukuba abe yikristale. Oko kukuthi, awudingi ipateni enamacala amathandathu kolu hlobo lwemvula.
Umkhenkce owenzeka kolu hlobo lwemvula intle kakhulu kwaye ayenzi zakhiwo ezinzima. Olu lwakhiwo luhle lwenzeka xa amaqondo obushushu eshushu ngokwaneleyo ukuba anyibilike iqhwa, kodwa ngaphandle kokulijika libe ngamanzi. Ngesi sizathu, ngexesha le-sleet, sinokubona amathontsi amanzi ephantse anyibilika ngohlobo lomkhenkce ngaphandle kokuba ngumkhenkce kwaye amanye amakhekheba ekhephu athe, ngenxa yokuba enobukhulu obukhulu, engakhange anyibilike ngexesha kwaye agcine ulwakhiwo lwawo oluphambili.
Mhlawumbi xa ujonga kubonakala ngathi luhlobo oluqhelekileyo lekhephu, kodwa xa ijongwa ngokusondeleyo okanye phantsi kwemikroskopu, kunokubonwa ukuba iinkozo ezifanayo nezesichotho ziyenziwa endaweni yeekristali zomkhenkce ezipheleleyo ezinesakhiwo esinamacala amathandathu. Kule meko banomkhenkce omncinci omnyama.
Umahluko phakathi kwale mvula ubonwa ikakhulu kulwakhiwo. Amaconsi amanzi alulwelo ngokwakhiwa, isichotho sinamanzi kwindawo eqinileyo, kwaye ikhephu lidlala ngomkhenkce omnyama kunye namakhekheba ekhephu.
Yintoni i-sleet
Amanzi ekhephu anokunikwa kwiimeko ezahlukeneyo. Kungenzeka ukuba ezinye izinto eziguquguqukayo zemozulu ezinje ngokufuma, uxinzelelo lweatmosferi kwaye, ke ngoko, ulawulo lomoya lubangela i-sleet enokuthi izole kakhulu ingaguqukela kwi-sleet. I-Sleet ayikho enye into ngaphandle kwesiphepho.
Yinto yendalo apho sinokuthi siqwalasele uqhwithela lwamanzi nekhephu elilungile kunye nolwakhiwo kunye nokufuduswa kwabo ngamandla nakwimigama emide yintshukumo yomoya. Ukuze i-sleet yenzeke, ukufuma okuhambelana kufanele kube malunga ne-100% kwaye umoya kufuneka ube ngaphantsi kweedigri zero. Kule meko, into eyenza ukuba amakhekhe ekhephu anyibilike abe ngumkhenkce amorphous ngumoya kunye nokwehla koxinzelelo lomoya. Ngokwesiqhelo, le nto ibonakala ikhatshwa sisikwere.
Ihlala ivela kwiindawo eziphakamileyo zeentaba, apho uxinzelelo lweatmosfera lusezantsi njengoko lubekwe phezulu kwaye ukufuma kunokugcinwa kuphezulu ngenxa yokuxinana kwemithi. Kuxhomekeke ekutyeni nase luhlobo luni. Ukuba ubuninzi be shrubby abuyi kuba nakho ukugcina ukufuma kuphezulu. Ukuze amaxabiso okufuma afumaneke, kufuneka ukufuma okuphezulu, ikakhulu okwenziwa ziindawo ezinamahlathi ezixineneyo kunye nokuphakama.
Ngokudityaniswa kokufuma, isaqhwithi kunye noxinzelelo olusezantsi kwindawo ephezulu, kuyakubakho imimoya eyomeleleyo ngokwaneleyo ukuba ibangele isaqhwithi xa iinyikima zomkhenkce zinyibilika. Le nto yenzeka ekwindla nasebusika nasentwasahlobo. Ixhaphake kakhulu entwasahlobo xa kukho iqabaka ethile kwaye ubuninzi behlathi buphezulu ngenxa yeentyatyambo kunye nexesha lokukhula kwezityalo ezininzi.
Njengoko ubona, kwindalo akukho nto inokuthi iphawulwe ngokupheleleyo kwaye isekwe ngeempawu ezizodwa. Singabo bahlula izinto ukuze siziqonde ngcono.
