Umphumela Wesivinini Somoya Ekwakhekeni Kwamagagasi Olwandle Olwandle lwaseJava
Ulwandle iJava lungenye yamanzi abaluleke kakhulu e-Indonesia, kokubili ngokwezomnotho, ezokuthutha, kanye nemvelo. Lawa manzi axhumanisa amachweba amakhulu eziqhingini zaseJava, eKalimantan, nasezindaweni ezizungezile, futhi asebenza njengomzila omatasa wokuthutha imikhumbi yokudoba kanye nemikhumbi yokuhweba. Ngemuva kwale misebenzi, ukuguquguquka kwamagagasi olwandle kudlala indima ebalulekile ekunqumeni ukuphepha kokuhamba, impumelelo yokudoba, kanye nomthelela ongaba khona wokuguguleka kogu. Esinye sezici ezibaluleke kakhulu ezithonya ukwakheka kwamagagasi oLwandle iJava isivinini somoya.
Amagagasi Olwandle kanye Nendima Yomoya
Amagagasi olwandle ngokuvamile akhiwa ukudluliselwa kwamandla kusuka emoyeni kuya ebusweni bamanzi. Uma umoya uvunguza phezu kobuso bolwandle, ukungqubuzana phakathi komoya namanzi kudala amagagasi amancane (amagagasi e-capillary). La magagasi abese "ebamba" amandla omoya engeziwe, akhule abe amagagasi amakhulu. Uma amandla edluliselwa emaningi, kulapho amagagasi ekhiqizwa khona aphezulu futhi amade.
Nokho, isivinini somoya akuyona yodwa into ebangela lokhu. Ku-oceanography, ukwakheka kwamagagasi kuthonywa yiziguquguquko ezintathu eziyinhloko: isivinini somoya, ubude bomoya, kanye nokulanda. Lezi ziguquguquko ezintathu zihlobene, kodwa ezimweni eziningi, ukwanda kwesivinini somoya yikona okushayela ngokushesha amandla amagagasi akhuphukayo.
Izici Zolwandle lwaseJava: Amanzi Angajulile Ayingqayizivele
Ulwandle lwaseJava alujulile kakhulu uma luqhathaniswa nolwandle oluvulekile. Ukujula kwalo okujwayelekile kungamamitha angamashumi, kanye nokwehluka okukhulu kwe-bathymetric eduze kwe-straits noma imisele emincane. Lokhu kujula kunegalelo ekuziphatheni okuphawulekayo kwamagagasi oLwandle lwaseJava:
1. Amagagasi “anqunyelwe” ekukhuleni kwawo ngokushesha kunasolwandle olujulile ngoba amandla amagagasi axhumana kalula nolwandle.
2. Ukungqubuzana kwangaphansi kunganciphisa ukuphakama kwamagagasi futhi kushintshe ukuma kwamagagasi, ikakhulukazi lapho amagagasi esondela ogwini.
3. Amagagasi angaba makhulu lapho kwehla ukujula, okwandisa ingozi yokuthi imikhumbi emincane ibhekane nokushaywa kwamagagasi noma ngisho nokufakwa ohlwini ngokweqile.
Ngakho-ke, oLwandle iJava, isivinini somoya esikhulayo singathinta ngokushesha ubuso bolwandle, kodwa ukukhula kwamagagasi nakho “kungama” ngokushesha kunasemanzini ajulile, kuye ngokuthi kuqondiswa kuphi nokuthi kuthathweni.
Ubudlelwano Phakathi Kwesivinini Somoya Nokuphakama Kwamagagasi
Kalula nje, uma isivinini somoya siphezulu, amagagasi aphezulu, uma nje ubude kanye nokudonsa kuvumela amagagasi ukuthi akhule. Njengoba umoya uvunguza ngamandla, amandla okungqubuzana kanye nokucindezela okuguquguqukayo okusebenza ebusweni bolwandle kuyanda. Lokhu kubangela ukuthi ukuphakama kwamagagasi (ukuphakama) kwande futhi ubude bamagagasi buvame ukwanda.
OLwandle iJava, imimoya enamandla ivame ukuhlotshaniswa nezinhlelo zemvula kanye nokuphazamiseka kwesimo sezulu sesifunda. Lapho isivinini somoya sikhuphuka kakhulu, abadobi bavame ukubona izinguquko ezisheshayo ku:
– Ubuso bolwandle buba nzima kakhulu (isimo solwandle siba sibi kakhulu)
– Amagagasi amafushane naminyene avele kuqala
– Ngemva kwamahora ambalwa, amagagasi angaba maningi futhi abe maningi, ikakhulukazi uma umoya uqondiswa ngendlela ezinzile.
Isigaba sokuqala sivame ukukhiqiza amagagasi endawo amafushane, angajwayelekile (ulwandle lomoya). Uma umoya uqhubeka isikhathi eside ngokwanele, amagagasi angakhula abe makhulu futhi ahleleke kakhudlwana.
Indima kaFetch oLwandle lwaseJava
I-Fetch ibanga elihanjwa umoya phezu kwamanzi avulekile ngaphandle kokuvinjelwa komhlaba. Ulwandle lwaseJava luzungezwe iziqhingi ezinkulu, ngakho-ke i-fetch incike kakhulu ekuqondeni komoya. Uma umoya uvunguza usuka ohlangothini olunikeza indlela ende oLwandle lwaseJava, amagagasi akhula kalula.
Isibonelo, uma umoya uvunguza usuka entshonalanga noma empumalanga eceleni kwe-longitudinal axis yoLwandle iJava, ukudonswa okude kungadala amagagasi abaluleke kakhulu. Ngokuphambene nalokho, uma umoya "uphambana" nomhlaba (isb., uvela ohlangothini oluhlangana ngokushesha nogu noma isiqhingi), amagagasi avame ukuba mancane, noma ngabe ijubane lawo liphezulu impela, ngoba amandla awanaso isikhala esanele sokukhiqiza amagagasi amakhulu.
Izinguquko Zesizini: Imvula YaseNtshonalanga kanye nemvula YaseMpumalanga
Ulwandle lwaseJava luthonywa kakhulu yimimoya yesizini (izimvula). Ngokuvamile:
– Imvula Yasentshonalanga (cishe ngoNovemba–Mashi): imimoya enamandla evela entshonalanga-enyakatho-ntshonalanga iletha umoya omanzi futhi ivame ukubangela imvula nesimo sezulu esibi. Isivinini somoya singanda ngezikhathi ezithile, ikakhulukazi lapho kuneziphazamiso zesimo sezulu ezifana nokujikeleza kwe-cyclonic endaweni ezungezile. Lezi zimo zingadala amagagasi aphazamisa ukuhamba, ikakhulukazi emikhunjini emincane.
– I-East Monsoon (cishe ngoJuni–Septhemba): imimoya enamandla evela empumalanga-eningizimu-mpumalanga, ivame ukoma. Ngezinye izikhathi, imimoya ingavunguza njalo futhi ngamandla amakhulu. Lokhu kuqina kubalulekile ngoba isikhathi eside sivumela amagagasi ukuba akhule yize uLwandle lwaseJava lungajulile kakhulu.
Ngamanye amazwi, akugcini nje ngokuthi umoya unamandla kangakanani, kodwa futhi nokuthi uhlala isikhathi esingakanani nokuthi uqondisa kanjani. Imimoya enamandla kakhulu kodwa emifushane ingadala amagagasi esikhashana anolaka, kanti imimoya emaphakathi kodwa eqinile ehlala amahora noma izinsuku ingadala amagagasi ahlelekile futhi asakazeke kabanzi.
Umphumela Wesivinini Somoya Esikhathini Samagagasi kanye ne-Spectrum
Amagagasi awagcini nje ngokuphakama, kodwa futhi aphathelene nesikhathi (isikhathi esiphakathi kwamagagasi amakhulu) kanye ne-spectrum (inhlanganisela yobukhulu bamagagasi). Isivinini somoya esiphezulu sivame uku:
- Kwandisa amandla ku-spectrum yamagagasi
- Kukhuthaza ukwakheka kwamagagasi anesikhathi eside uma ukuthathwa nobude besikhathi kwanele
- Kudala izimo zolwandle "ezinzima" ngamagagasi amafushane ezigabeni zokuqala zokukhula
Emanzini afana noLwandle iJava, amagagasi aminyene, esikhathi esifushane avame ukuba yinselele kakhulu emikhunjini emincane kunamagagasi amade, avamile, njengoba ukunyakaza komkhumbi kuba okungazinzile futhi ingozi yokungena kwamanzi iyanda.
Imiphumela Emagwini Nasemisebenzini Yabantu
Isivinini somoya esikhuphula amagagasi sithinta ngqo izindawo ezisogwini oLwandle iJava, okuhlanganisa nogu olusenyakatho lweJava kanye nezingxenye zeKalimantan. Amagagasi aphezulu angandisa amandla emithelela yasogwini, asheshise:
– Ukuqhekeka kogu ezindaweni ezisengozini
– Ukulimala kwezakhiwo zasogwini njengezinsika ezincane noma imigoqo elula
– Ukukhukhuleka kwamanzi angajulile, okungathinta imvelo efana nemibhede yotshani basolwandle kanye namadwala e-coral ezindaweni ezithile
Ngokuphathelene nokuthunyelwa kwemikhumbi kanye nokudoba, ukwanda kwamagagasi ngenxa yemimoya enamandla kungaholela ekubambezelekeni kokuhamba kwemikhumbi, ingozi eyengeziwe yezingozi, kanye nokuncipha kwezinsuku olwandle kubadobi. Ngaphezu kwalokho, ukuqonda amaphethini omoya namagagasi kusiza ukuhlela: ukukhetha imizila ephephile, ukunquma izikhathi zokuhamba ngomkhumbi, kanye nokuthuthukisa imiklamo yemikhumbi kanye nechweba.
Isiphetho
Isivinini somoya sinethonya elinamandla ekwakhekeni kwamagagasi olwandle oLwandle iJava ngokudluliselwa kwamandla avela emkhathini aye ebusweni bamanzi. Kodwa-ke, umthelela wawo uhlala uthonywa yizici ezimbili eziyinhloko ezibangela lokhu: ubude bomoya kanye nokuthathwa komoya okutholakalayo, okuncike kakhulu ekuqondisweni komoya kanye nendawo yezwe yoLwandle iJava. Ngenxa yokuthi uLwandle iJava alujulile futhi luzungezwe umhlaba, amagagasi angakhula ngokushesha kodwa futhi asengozini enkulu yokuxhumana phansi kolwandle.
Ukuqonda ubudlelwano phakathi kwesivinini somoya namagagasi oLwandle iJava kubalulekile ekuphepheni kwemikhumbi, imisebenzi yokudoba, kanye nokunciphisa izingozi zasogwini. Ngolwazi oluthuthukisiwe lwesimo sezulu kanye nolwazi lwezolwandle, imiphakathi yasogwini kanye nabadlali bezolwandle bangenza izinqumo eziphephile neziphumelelayo ngokuphendula amandla amagagasi oLwandle iJava.
Uma ufisa, ngingangeza idatha yesibonelo (isb., amabanga esivinini somoya kanye nokulinganisa ukuphakama kwamagagasi), ngifake izinkomba zesayensi, noma ngilungise lesi sihloko ukuze sibe sezemfundo kakhulu (ngezigaba zendlela kanye nezinkomba).
