Nakuba imbangela yokulahlekelwa okudabukisayo kwe-Air France Flight 447 ingakacaciswa, esikwaziyo ngokuqinisekile ukuthi indiza yayindiza phakathi kwezinxushunxushu phezu kolwandle i-Atlantic ngesikhathi indiza yehla. Kufike ngesikhathi lapho i-NASA ixhasa ngezimali ukuthuthukiswa kohlelo lwe-prototype ukuhlinzeka izindiza ngezibuyekezo mayelana neziphepho ezinamandla neziyaluyalu njengoba zindiza ezindaweni ezikude zolwandle.
Ososayensi e-National Center for Atmospheric Research (NCAR) e-Boulder, Colorado, ngokubambisana nozakwabo eNyuvesi yaseWisconsin, bakha uhlelo oluhlanganisa idatha yesathelayithi namamodeli wesimo sezulu sekhompyutha ngamasu obuhlakani bokwenziwa ahlabayo. Umgomo uwukubona nokubikezela iziphepho ezishintsha ngokushesha nezinye izindawo ezingaba neziyaluyalu.
“Iziyaluyalu ziyimbangela ehamba phambili yokulimala kwezindiza zezentengiselwano,” kusho uJohn Haynes, umphathi wohlelo ku-Applied Sciences Programme ye-Earth Science Division ekomkhulu leNASA eWashington. "Lo msebenzi omusha wokuthola amathuba okuba nesiyaluyalu esihambisana neziphepho zolwandle kusetshenziswa izinkomba ezibalulekile ezisemkhathini ubaluleke kakhulu kubashayeli bezindiza."
Isistimu yakhelwe ukusiza ukuqondisa abashayeli bezindiza kude nesimo sezulu esishubile. Izinhlobonhlobo zokubhekwa kwemikhumbi-mkhathi ye-NASA ziyasetshenziswa kuphrojekthi, okuhlanganisa idatha evela kumasathelayithi e-NASA e-Terra, Aqua, Tropical Rainfall Measuring Mission, CloudSat, kanye ne-CALIPSO.
Uhlelo lwe-prototype luzohlonza izindawo ezineziyaluyalu ezindaweni ezicacile zomkhathi, kanye naphakathi kweziphepho. Isendleleni ezohlolwa ngonyaka ozayo. Abashayeli bezindiza emizileni ekhethiwe ye-transoceanic bazothola izibuyekezo zesikhathi sangempela sezinxushunxushu futhi banikeze impendulo. Uma isistimu iqedwa, izohlinzeka abashayeli bezindiza nezilawuli ezisekelwe phansi ngamamephu asekelwe emibhalweni kanye nezibonisi zezithombe ezibonisa izifunda okungenzeka kube nezinxushunxushu neziphepho.
"Okwamanje abashayeli bezindiza banolwazi oluncane lwesimo sezulu njengoba bendiza ezindaweni eziqhelile zolwandle, okuyilapho kwenzeka khona iziyaluyalu ezimbi kakhulu," kusho usosayensi uJohn Williams, omunye wephrojekthi ehamba phambili e-NCAR. “Ukuhlinzeka abashayeli bezindiza okungenani ngesithombe esilinganiselwe sokuvela kweziphepho kungabasiza ukubaqondisa ngokuphepha ezindaweni ezinesiyaluyalu esingase sibe sibi kakhulu.”
I-NCAR okwamanje ihlinzeka ngamamephu esikhathi sangempela wesiyaluyalu ezindaweni eziphakeme ezihlukene ezwekazini lase-United States. UWilliams nozakwabo bakhela phezu kwalobu buchwepheshe bokuhlonza isiphithiphithi phezu kolwandle. Ithimba lidale amamephu omhlaba esiphithiphithi somoya esicacile asuselwa kumamodeli wesimo sezulu wekhompuyutha womhlaba wonke ahlanganisa umoya nokunye ukuphazamiseka emkhathini. Bedweba izithombe zesathelayithi zeziphepho, ososayensi baye badala imibono yomhlaba wonke ngeziqongo zamafu esiphepho. Iziqongo zamafu eziphakeme ngokuvamile zihlotshaniswa neziphepho ezinamandla kakhulu, nakuba kungenjalo nesiyaluyalu.
Isinyathelo esilandelayo siwukukhomba izindawo okungenzeka kube nezinxushunxushu ngaphakathi naseduze neziphepho ezinamandla. Ithimba lizocwaninga ukuhlobana phakathi kweziphepho nesiyaluyalu phezu kwezwekazi lase-United States, lapho isimo sezulu siqashelwa eduze, bese lisho amaphethini okuyaluza kweziphepho phezu kolwandle.
Ngokungeziwe ekunikezeni izindiza nezilawuli zasemhlabeni ngamamephu akamuva kuya kwamaminithi eziyaluyalu, ithimba le-NCAR liphendukela kumasu okwenziwa kobuhlakani bokwenziwa, okwaziwa ngokuthi "amahlathi angahleliwe," ukuze linikeze izibikezelo zesikhashana.
Amahlathi angahleliwe, abonakale ewusizo ekubikezeleni ukuduma kwezulu phezu komhlaba, ahlanganisa izihlahla eziningi zokunquma lapho ngasinye senza “ivoti” likayebo-noma-cha ezintweni ezibalulekile zesiphepho ezindaweni ezizayo ngesikhathi nasemkhathini. Lokhu kwenza ososayensi bakwazi ukubikezela ukuhamba namandla kwesiphepho emahoreni ambalwa alandelayo.
“Umgomo wethu uwukunikeza abashayeli bezindiza isithombe esibuyekezwa njalo seziphepho ezingase zise ngaphambili njengoba zindiza phezu kolwandle, ukuze bathathe isinyathelo sokunciphisa uthuthuva futhi bavimbele indiza yabo engozini,” kuchaza usosayensi we-NCAR uCathy Kessinger, ithimba lephrojekthi. ilungu.
Iphrojekthi ye-NCAR ixhaswe yi-NASA's Applied Sciences Programme, efuna ukuhumusha ukutshalwa kwezimali kwe-NASA ekuhlolweni komhlaba kube izinhlelo zokusebenza ezibhekana nezinkinga zangempela. Lolu hlelo kanye nozakwethu basebenzela ukuvala igebe phakathi kwemiphumela yocwaningo kanye nemikhiqizo yesimo sezulu esisebenzayo sezindiza ezindaweni ezifana neqhwa elingaphakathi endizeni, isimo sezulu esiguqukayo, isiphithiphithi, umlotha wentaba-mlilo, nesimo sezulu sasemkhathini.
LOKHO ONGAKUTHATHE KULESI SIHLOKO:
- While the cause of the tragic loss of Air France Flight 447 has yet to be determined, what we do know for sure is that the aircraft was flying through turbulence over the Atlantic Ocean at the time the plane went down.
- “Our goal is to give pilots a regularly-updated picture of the likely storms ahead as they fly over the ocean, so they can take action to minimize turbulence and keep their aircraft out of danger,”.
- Scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, in partnership with colleagues at the University of Wisconsin, are developing a system that combines satellite data and computer weather models with cutting-edge artificial intelligence techniques.
