KwiMeteorology kubalulekile ukuba ufunde ngotshintsho olwenzeka kwimeko-bume ngexesha langempela ukuxela kwangaphambili ukuba kuzakwenzeka ntoni. Umoya yindawo apho iintshukumo zobunzima zenzeka ngokulula kakhulu. Ngale ndlela, ukutshintshiselana ngobushushu ngokuhamba nkqo nangokuthe tye kuvunyelwe. Ukuthuthwa okuthe tye kobushushu bezinye izixa zomzimba ngumoya kuthiwa yi-advection. Ukwazisa yinjongo yeli nqaku.
Siza kuhlalutya ukubaluleka kokwazi i-advection ekhoyo kwi-atmosfera ukuze sazi i-meteorology kunye notshintsho ekuhambeni kwexesha. Ngaba uyafuna ukufunda ngakumbi ngayo? Qhubeka ufunda
Yintoni advection
Kwiimeteorology kuqhelekile ukusebenzisa igama elithi convection ukumisela intshukumo ethe nkqo. Ixabiso lesantya sale ntshukumo alidluli ngokubanzi ukuya kwikhulu leentshukumo ezithe tye. Ke ngoko, kunokuqatshelwa ukuba amafu akhula ngokuthe nkqo enze kancinci kwaye ayakwazi ukuthatha usuku olupheleleyo.
Ukuhamba okuthe tyaba komoya womoya kwenzeka kwizinga elikhulu kwihlabathi liphela. Yiyo ehambisa amandla obushushu ukusuka kwimimandla yetropiki ukuya kwimimandla esecaleni. Bayakwazi ukudlulisa amandla ukusuka kwelinye icala lehlabathi ukuya kwelinye, ukuhamba amawaka eekhilomitha kude. Kolu thutho luthe tye lubalaselayo kwaye lubaluleke ngakumbi kwaye luyaqhubeka kunamaza omoya athe nkqo.
Kwiimeteorology kunye nolwandle ngokwasemzimbeni, ukubhengeza kudla ngokubhekiswa kuko ukuhanjiswa kwepropathi yomoya okanye yolwandle, njengobushushu, ukufuma okanye ityuwa. I-Meteorological okanye i-advection ye-oceanographic ilandela umphezulu we-isobaric kwaye ke ngoko ubukhulu becala buthe tye. Kuyafana nokuthuthwa kwepropati ye-atmospheric ngomoya. Ngapha koko, ukuqonda i-advection kubalulekile ekuqondeni izinto ezinje ukumila kwenkungu kunye nezinye iinkqubo zemozulu, kunye nokuqonda iintlobo zenkungu oko kunokuvela.
Iimpawu zokubonisa
Ukuwuqonda ngcono lo mbono siza kunika imizekelo yokuthambeka okufudumeleyo nokubanda. Ukufudumala okufudumeleyo kukuba ubushushu obuqhutywa ngumoya buye kwenye indawo. Ngokuchasene noko, i-advection ebandayo kukuthutha okubandayo ukuya kwezinye iindawo. Nangona kunjalo, omabini la manzi athutha amandla ukusukela, nangona umoya ubushushu obusezantsi, usenamandla.
Kuqikelelo lwemozulu, igama elithi advection libhekisa kuthutho lobungakanani obunikiweyo licandelo elithe tye lomoya. Ukuba sine-advection ebandayo, ihlala ibhekisa kwindawo efudumeleyo. Xa kukho i-advection efudumeleyo, iyenzeka phezu kwemihlaba ebandayo kunye neelwandle kwaye ukupholisa kwenzeka ngaphantsi. Ukwazi ezi ziganeko kubalulekile ukuze uziqonde inkungu nenkungu ezinokuthi zenzeke kwimimandla ethile, kuba zinefuthe kwi ubushushu ngexesha lobusuku obucacileyo.
Izizathu zokunyanzeliswa
Kukho iintlobo ezininzi zokuncipha komphunga wamanzi. Iyokuqala yimisebe kwaye okwesibini yi-advection. Umphunga wamanzi unokuxutywa ngokudibanisa izihlunu zomoya kunye nokupholisa ngokwandiswa kwe-adiabatic. Le yokugqibela ingunobangela wolwakhiwo olukhulu lwamafu.
Kwi-advection yokupholisa, ubunzima bomoya ofudumeleyo, omanzi buthuthwa ngokuthe tye, bongeza kumphezulu okanye ubunzima bomoya opholileyo.. Ngenxa yokunxibelelana phakathi kwentlama efudumeleyo nengqele, ubushushu bomoya wentlama efudumeleyo buyehla buhambelane nobandayo. Ngale ndlela, i-cloudiness iqala ukwenza, nje ukuba ubushushu bobunzima obufudumele buyancipha kwaye bufike kwindawo yombethe kwaye buhluthe ngamanzi. Ngaphezu koko, le nto inxulumene ne inkungu nenkungu enokubonwa kwindalo.
Ukupholisa imitha kwenzeka xa umhlaba ushushu lelanga. Uluhlu olusondeleyo kumphezulu luqala ukufudumeza ngenxa yoko. Ngesi sizathu, amaqamza omoya ashushu enza kwaye, ngenxa yokuxinana kwawo asezantsi, athambekele ekunyukeni ade ahlangane kwezona ndawo ziphakamileyo nezibandayo. Xa befika kumanqanaba aphezulu, iqondo lobushushu liqala ukwehla kwaye bayahlutha, bajiye kwaye benze ilifu.
Ukupholisa i-Adiabatic
Kungenxa yokwahluka kobushushu ngenxa yokwehla koxinzelelo lwangaphakathi njengoko umntu enyukela phezulu. Uninzi lwemisinga ethe nkqo inokutshintsha oku kupholisa, ikwabizwa ngokuba sisandi sokufudumeza ubume bendalo.
Xa umoya unyuka, uxinzelelo lomoya luyancipha. Ngesi sizathu, ukuhamba kunye nokukhuhlana kweemolekyuli nako kuyehla, oko ke kupholisa umoya. Njengesiqhelo, ihlala yehla malunga ne-6,5 iidigri kwikhilomitha nganye yokuphakama.
Ukuba umoya womile, ukwehla kobushushu kuphezulu kakhulu (kujikeleze iidigri ezili-10 kwikhilomitha nganye ukuphakama). Ngokuchasene noko, ukuba umoya ugcwele, ukuhla kwawo kuya kuba njalo iidigri ezi-5 kuphela ngekhilomitha. Ukuqonda le nkqubo kubalulekile ekuqondeni indlela amafu enza ngayo kunye nobudlelwane babo kunye isiphango kubusuku obucacileyo, kunye nokuqonda iziganeko ezinxulumene ne-advection kwi-meteorology.
Amafu enziwe ngeseti yamasuntswana amancinci kakhulu kunye namanzi acocekileyo, umkhenkce okanye umxube wazo zombini. Zenziwe ngokunyibilika komphunga wamanzi emoyeni. Oku kubangela ukuthambeka ukuhambisa ingqele ukusuka emafini kuyise kwezinye iatmosfera nokusasazeka.
Utshintsho kubushushu ngenxa ye-advection
I-Advection ineeyunithi zobushushu kwiyunithi nganye yexesha. Ibonisa ukuguquguquka kwe-thermal eyenzeka kwinqaku ngenxa yokufika komoya othwala umoya kwiqondo lobushushu elahlukileyo.
Ukuba, umzekelo, umoya ufika usuka kwindawo ebandayo kwindawo esilinganisa kuyo, siya kuba namava okupholisa kwaye i-advection yeqondo lobushushu iya kuba linani elithabathayo elinokusixelela kanye ukuba zingaphi iidigri kwiyunithi nganye yexesha ubushushu buhlayo.
Ukupholisa umoya kunokwenzeka ngezizathu ezahlukeneyo:
- Ngenxa yobushushu bomhlaba Ukuhanjiswa kwamahhala kuveliswa yimitha yelanga.
- Ngomzobo womhlaba, Ngenxa yokunyuka kwamanqanaba omoya ukuwela intaba, ukunyanzelwa okunyanzelekileyo kuyenzeka.
- Umoya unyanzelekile ukuba unyuke kufutshane neendawo ezishushu nezibandayo, ivelisa intshukumo ethe tye yomoya obandayo, eveliswe yintshukumo ethe tyaba kwimozulu eshushu yokunyuka.
Njengoko ubona, i-advection yinto ebaluleke kakhulu ekufuneka uyiqwalasele kwi-meteorology. Imeko entle xa kusenziwa uqikelelo lwemozulu kunye nokwazi amandla kunye nozinzo lomoya.
