Ngesikhathi sasehlobo kwenzeka izimo zezulu ezingajwayelekile ezidinga izimo ezikhethekile ukuze zenzeke. Esinye salezi zenzakalo si ukuqhuma okushisayo. Lesi yisenzakalo esenzeka lapho izulu eliwayo lihwamuka njengoba liwela ungqimba lomoya owomile noma owomile kakhulu endaweni efudumele. Ukuze uthole ulwazi olwengeziwe, kuyancomeka ukuthi uxhumane nendatshana ethi izici zokuqhuma okushisayo nemiphumela.
Kulesi sihloko sizokutshela mayelana nezici, umsuka kanye nemiphumela yokushaywa kwe-thermal.
Izici kanye nemvelaphi yokushaywa okushisayo
Njengoba umoya wehla, uyaphola futhi ube mkhulu kunomoya ozungezile. Lapho umoya uphola, uba minyene kunomoya owuzungezile, okuwubangela ukuba ucwile phezulu ngesivinini esisheshayo kunomoya owuzungezile. Uma yonke imvula equkethwe emoyeni owehlayo isihwamukile, umoya uyoma ngokuphelele futhi awusakwazi ukuhwamuka. Njengoba umoya wehla, Ishiswa ukucindezelwa komkhathi.
Umoya kufanele udlule kwenye inqubo ngemva kokuba umoya owehlayo ungasakwazi ukupholiswa, kodwa umoya uyaqhubeka wehlela phezulu ngenxa yomfutho wawo. Njengoba umoya ucindezelwa, uyashisa. Umoya oshisayo, owomile uqala ukucwila ngasemkhathini woMhlaba, uthola umfutho njengoba uhamba. Lomoya oshisayo, nowomile uyaqhubeka nokuwa uze ufinyelele phezulu, lapho umfutho wawo usakazekela ngokuvundlile kuwo wonke umhlaba kuzo zonke izinhlangothi. Lokhu kubangela ukufutheka okunamandla ngaphambili (ukungena komoya oshisayo, owomile ovela phezulu kubangela ukuthi izinga lokushisa langaphezulu likhuphuke ngokushesha okukhulu namazolo angaphezulu ehle ngokushesha okukhulu).
Kubalulekile ukukhumbula ukuthi njengoba izinga lokushisa likhuphuka, ukuminyana kuyancipha (lo moya ocwilayo usuvele uhamba ngokushesha kakhulu, futhi ukwehla kokuqina kwalo moya akuwunciphisi). Ukushisa okushisayo kuvame ukuhambisana nomoya onamandla futhi kunzima ukubikezela. Zingenzeka ezindaweni ezaziwa ngokusekelwe kudatha yesimo sezulu kusukela ezinsukwini ezedlule, noma zingamodelwa. Ukuze uqonde kangcono lesi simo, kuyasiza ukubonana nolwazi mayelana ne-.
Izibonelo zokushisa okushisayo
Ezinye izibonelo zokushisa okushisayo noma okufudumele emhlabeni jikelele zihlanganisa ukwanda izinga lokushisa elingu-86 degrees e-Abadan, e-Iran, lapho inqwaba yabantu yafa khona. Izinga lokushisa likhuphuke lisuka ku-37,8 laya ku-86 degrees emizuzwini emibili nje. Esinye isibonelo singu-66,3 degrees Celsius e-Antalya, eTurkey ngoJulayi 10, 1977. Le mibiko ayisemthethweni.
ENingizimu Afrika, ukuqhuma okushisayo kwashisisa izinga lokushisa lisuka ku-19,5 degrees laya ku-43 degrees ngemizuzu emihlanu nje phakathi nokuduma kwezulu phakathi kuka-9 no-9:05. Lokhu kwenzeke eKimberley. Kunemibiko engekho emthethweni evela e-Portugal, Iran, naseTürkiye, kodwa alukho olunye ulwazi oluqinisekisayo. Ukubhekwa kwesimo sezulu ngaleso sikhathi akubonisi zimpawu zokuthi le mibiko yayinembile. Isazi sesimo sezulu sithe izinga lokushisa lenyuka lafinyelela ku-43 degrees Celsius, kodwa ithemometha yakhe ibingasheshi ngokwanele ukuthi ifike endaweni ephakeme kakhulu. Izinga lokushisa lehla laya ku-19,5°C ngo-21:45 p.m. Ukuze uthole imininingwane eyengeziwe ngalolu hlobo lwezenzakalo zomkhathi, ungabuyekeza isihloko sethu kokuthi.
Amacala eSpain
Ezweni lakithi kukhona nezinye izigameko zokuqhuma okushisayo. Ngokuvamile lezi zenzakalo zihlotshaniswa nokuvunguza komoya okunamandla kanye nokwenyuka okungazelelwe kwezinga lokushisa. Amanzi aqukethwe kulo moya ayacwila futhi ahwamuke ngaphambi kokuba afinyelele phansi. Kungalesi sikhathi lapho umoya owehlayo ushisa khona ngenxa yokucindezela okubangelwa isisindo esikhulayo sekholomu yomoya ngaphezu kwawo. Umphumela uba lokhu kushisa komoya okuzumayo kanye nokuncipha komswakama.
Ochwepheshe beMeteorology bathi amafu angabonakala eguquguquka ngokushesha abheke phezulu futhi akhombise ukuvuselelwa okuqinile okuqondile. Yize ibukeka njengeyodwa, zingamafu aguqukela ngokushesha zibheke phezulu ngakho-ke ingabukeka njengeziphepho. Ukuqhuma okufudumele kuvame ukwenzeka ebusuku noma ekuseni kakhulu lapho izinga lokushisa ebusweni liphansi kunesendlalelo ngokushesha ngenhla kwalo.
Ngenxa yemiphumela elimazayo, le mizila efudumele ingadideka nezivunguvungu njengoba nayo ihlotshaniswa nokuvunguza komoya okunamandla. Nokho, ingahlukaniswa ngomkhondo womonakalo ewushiyayo. Icala eliphawulekayo lenzeke eCastellon, lapho Lokhu kubizwa ngokuthi ukushaywa okomile futhi kwenzeka lapho izulu liwa futhi lihwamuka njengoba lidlula ongqimbeni lomoya owomile noma owomile kakhulu endaweni efudumele.. Ngokuvamile, le mvula yesiphepho iyahwamuka, ipholise umoya oya phansi nomfula futhi ibangele ukuwa ngokushesha. Umoya uyashisa njengoba umoya wehla ngesivinini ubheke endaweni yoMhlaba.
Kuleli qophelo, umoya ofinyelela phezulu ushisa kakhulu, ngakho ungabangela ngokushesha ukwanda okukhulu kwezinga lokushisa, njengoba kwabhalwa esikhumulweni sezindiza saseCastellon. Ngomhla zi-6 kuJulayi, 2019, kwabangela ukuqhuma okushisayo e-Almería izinga lokushisa lenyuke ngaphezu kuka-13 ºC, lisuka ku-28,3 ºC laya ku-41,4 ºC, emizuzwini engama-30 nje kuphela, ngokusho kwamarekhodi e-Aemet. Lolu hlobo lwesigameko lubalulekile emkhakheni wesimo sezulu futhi kuyancomeka ukuthi uthintane ngaso ukuze usiqonde kangcono.
ubudlelwano nezivunguvungu
Imimoya enamandla evamile ededelwa phakathi neziphepho ezinamandla, ehambisana nemvula enamandla, izivunguvungu ezesabekayo kakhulu zezindiza. Kulokhu, akhiwa inhlanganisela yezimo: Isisindo somoya esivunguvungwini siyaphola, iba minyene (nzima) futhi iwe ngokushesha njengoba isondela phansi.
Icala lokuqhuma kwe-thermal likhethekile kakhulu futhi kufanele linikezwe ukucushwa komkhathi okunembayo ukuze kwenzeke, ngokuyisisekelo ukusatshalaliswa komkhathi maphakathi nezingqimba eziphansi kuyashisa kakhulu futhi komile. Uma besingenza isivunguvungu esibolayo esivuthiwe emkhathini onjalo, imvula ehambisana nokuqhuma okwehlayo izohwamuka, kusize ukupholisa umoya owehlayo.
Nokho, kunesikhathi lapho imvula ingasekho engahwamuka. Kusukela kulo mzuzu kuqhubeke, njengoba isisindo somoya siqhubeka nokwehla, inqubo ye-thermodynamic ebizwa ngokuthi i-adiabatic compression iqala ukwenzeka. Lokhu kwenzeka ngoba lesi sixuku somoya sinekholomu yomoya enkulu ngaphezu kwaso, sicindezela ngenxa yesisindo esisisekelayo. Ukucindezelwa kwe-Adiabatic kukhiqiza ukushisa kwesisindo somoya kanye nokulahlekelwa umswakama emoyeni.
