I-skyline yase-Aggieland izoshintsha kule mpelasonto lapho kufakwa uhlelo olusha lwe-radar yesimo sezulu ophahleni lwe-Eller Oceanography and Meteorology Building yaseTexas A&M University.
Ukufakwa kwe-radar entsha kuwumphumela wokubambisana phakathi kwe-Climavision kanye noMnyango Wezesayensi Yesimo Sezulu waseTexas A&M ukuze kucatshangelwe kabusha indlela abafundi, othisha kanye nomphakathi abafunda futhi basabela ngayo ezimweni zezulu.
I-radar entsha ithatha indawo ye-Agi Doppler Radar (ADRAD) esindala ebilokhu ibusa i-Agilan kusukela kwakhiwe i-Operations and Maintenance Building ngo-1973. Ukuvuselelwa kokugcina okukhulu kwe-ADRAD kwenzeka ngo-1997.
Uma isimo sezulu sivuma, ukususwa kwe-ADRAD nokufakwa kwe-radar entsha kuzokwenzeka kusetshenziswa indiza enophephela emhlane ngoMgqibelo.
“Izinhlelo ze-radar zanamuhla ziye zathuthukiswa kaningi ngokuhamba kwesikhathi, okuhlanganisa ubuchwepheshe obudala nobusha,” kusho uDkt. Eric Nelson, uprofesa osizayo wesayensi yomoya. “Nakuba izingxenye ezifana ne-receiver yemisebe kanye ne-transmitter zatholwa ngempumelelo, ukukhathazeka kwethu okuyinhloko kwakuwukujikeleza kwazo ngomshini ophahleni lwesakhiwo esisebenzayo. Ukusebenza kwe-radar okuthembekile kwanda kakhulu futhi kwangaqiniseki ngenxa yokuguga nokudabuka. Nakuba ngezinye izikhathi kusebenza kahle, ukuqinisekisa ukusebenza okuqhubekayo kwaba yinkinga ebalulekile, futhi lapho kuvela ithuba le-Climavision, kwaba nomqondo osebenzayo.”
Uhlelo olusha lwe-radar luyi-radar ye-X-band enikeza ukutholwa kwedatha okunesisombululo esiphezulu kunamakhono e-S-band e-ADRAD. Lune-antenna engamamitha angu-8 ngaphakathi kwe-radome engamamitha angu-12, okuhlukile kakhulu kuma-radar amadala ayengenaso isivikelo sokuwavikela ezimweni zemvelo ezifana nesimo sezulu, udoti kanye nomonakalo ongokwenyama.
I-radar entsha yengeza amakhono okubumbana okuphindwe kabili kanye nokusebenza okuqhubekayo, okuwukuthuthuka okubaluleke kakhulu kunokwandulelayo. Ngokungafani ne-ADRAD eyodwa evundlile, ukubumbana okuphindwe kabili kuvumela amagagasi e-radar ukuthi ahambe kuzo zombili izindiza ezivundlile nezivundlile. UDkt. Courtney Schumacher, uprofesa wesayensi yomoya eTexas A&M University, uchaza lo mqondo ngokufanisa izinyoka namahlengethwa.
“Cabanga ngenyoka phansi, efanekisela ukuhlukaniswa okuvundlile kwe-radar endala,” kusho uSchumacher. “Uma kuqhathaniswa, i-radar entsha iziphethe njengehlengethwa, ikwazi ukuhamba ngendiza eqondile, okuvumela ukubonwa kokubili kobukhulu obuvundlile nobokuma mpo. Leli khono lisivumela ukuthi sibone ama-hydrometeor ngobukhulu obune futhi sihlukanise phakathi kweqhwa, iqhwa neqhwa kanye nesichotho, futhi sihlole izici ezifana nenani kanye namandla emvula.”
Ukusebenza kwayo okuqhubekayo kusho ukuthi i-radar inganikeza umbono ophelele, onesinqumo esiphezulu ngaphandle kwesidingo sokuba othisha nabafundi bahlanganyele, inqobo nje uma izinhlelo zesimo sezulu ziseduze.
“Indawo ye-radar ye-Texas A&M iyenza ibe i-radar ebalulekile yokubuka ezinye zezenzakalo zesimo sezulu ezithakazelisayo kakhulu futhi ngezinye izikhathi eziyingozi,” kusho uDkt. Don Conley, uprofesa wesayensi yesimo sezulu eTexas A&M. “I-radar entsha izohlinzeka ngamasethi edatha ocwaningo amasha ocwaningo lwesimo sezulu esinzima nesiyingozi sendabuko, kuyilapho futhi ihlinzeka ngamathuba engeziwe kubafundi be-undergraduate okwenza ucwaningo lokwethula besebenzisa amasethi edatha endawo abalulekile.”
Umthelela we-radar entsha udlulela ngale kwezemfundo, uthuthukisa kakhulu izinsizakalo zokubikezela isimo sezulu kanye nezexwayiso emiphakathini yendawo ngokwandisa ukumbozwa kanye nokwandisa ukunemba. Amakhono athuthukisiwe abalulekile ekukhipheni izixwayiso zesimo sezulu ezifika ngesikhathi nezinembile, ukusindisa izimpilo kanye nokunciphisa umonakalo wempahla ngesikhathi semicimbi yesimo sezulu esibi. Isiteshi saseBryan College, esasisendaweni "engenawo ama-radar", sizothola ukumbozwa okugcwele ezindaweni eziphakeme, okwandisa ukulungela komphakathi kanye nokuphepha.
Idatha yerada izotholakala kubalingani bakahulumeni beClimavision, njengeNational Severe Storms Laboratory, kanye namanye amaklayenti eClimavision, okuhlanganisa nabezindaba. Kungenxa yomthelela ophindwe kabili ekuphumeleleni kwezemfundo kanye nokuphepha komphakathi ukuthi iClimavision inomdlandla kakhulu ngokubambisana neTexas A&M ukuthuthukisa irada entsha.
“Kuyajabulisa ukusebenza neTexas A&M ukufaka i-radar yethu yesimo sezulu ukuze kugcwaliswe izikhala ensimini,” kusho uChris Good, i-CEO yeClimavision eseLouisville, eKentucky. “Le phrojekthi ayigcini nje ngokwandisa ukumbozwa okubanzi kwamakhampasi amanyuvesi namakolishi, kodwa futhi inikeza abafundi ulwazi olusebenzayo lokufunda idatha esezingeni eliphezulu ezoba nomthelela wangempela emiphakathini yendawo.”
I-radar entsha ye-Climavision kanye nokubambisana noMnyango Wezesayensi Yomoya kuphawula ingqophamlando emlandweni ocebile we-Texas A&M wobuchwepheshe be-radar, obuqala ngawo-1960 futhi obulokhu buhamba phambili ekusunguleni izinto ezintsha.
“I-Texas A&M ibilokhu idlala indima ephambili ocwaningweni lwe-radar yesimo sezulu,” kusho uConley. “USolwazi Aggie ube nesandla ekutholeni amaza afanele kanye nama-wavelength okusetshenziswa kwe-radar, wabeka isisekelo sentuthuko ezweni lonke kusukela ngawo-1960. Ukubaluleka kwe-radar kwabonakala ngokwakhiwa kwesakhiwo se-Bureau of Meteorology ngo-1973. Lesi sakhiwo saklanywa ukuze sikwazi ukugcina nokusebenzisa lobu buchwepheshe obubalulekile.”
Lobu buchwepheshe budale izinkumbulo ezinhle kubafundisi be-Texas A&M University, abasebenzi kanye nabafundi kuwo wonke umlando we-radar njengoba bethatha umhlalaphansi.
Abafundi baseTexas A&M University babesebenzisa i-ADRAD ngesikhathi seSiphepho i-Ike ngo-2008 futhi badlulisela ulwazi olubalulekile kwiNational Weather Service (NWS). Ngaphezu kokuqapha idatha, abafundi bahlinzeka ngokuphepha kwemishini kuma-radar njengoba iziphepho zisondela ogwini futhi baqapha namasethi edatha abalulekile angadingeka yiNational Weather Service.
NgoMashi 21, 2022, i-ADRAD yanikeza usizo oluphuthumayo ku-NWS lapho ama-supercell okuqapha i-radar e-KGRK Williamson County asondela eBrazos Valley ekhutshazwa okwesikhashana yisiphepho. Isexwayiso sokuqala sesiphepho esakhishwa ngalobo busuku ukulandelela i-supercell eceleni komugqa osenyakatho weBurleson County sasisekelwe ekuhlaziyweni kwe-ADRAD. Ngosuku olulandelayo, kwaqinisekiswa iziphepho eziyisikhombisa endaweni yesixwayiso ye-NWS Houston/Galveston County, futhi i-ADRAD yadlala indima ebalulekile ekubikezeleni nasekuxwayiseni ngesikhathi sesehlakalo.
Ngokubambisana kwayo ne-Climavision, i-Texas A&M Atmopher Sciences ihlose ukwandisa kakhulu amakhono esistimu yayo entsha ye-radar.
“I-radar ye-AjiDoppler isisebenzele kahle i-Texas A&M kanye nomphakathi amashumi eminyaka,” kusho uDkt. R. Saravanan, uprofesa kanye nomqondisi woMnyango Wezesayensi Yomoya eTexas A&M. “Njengoba isondela ekupheleni kokuphila kwayo okuwusizo, siyajabula ukwakha ubudlelwano obusha ne-Climavision ukuqinisekisa ukuthi izothathelwa indawo ngesikhathi esifanele. Abafundi bethu bazokwazi ukufinyelela idatha yakamuva ye-radar yemfundo yabo yesimo sezulu. “Ngaphezu kwalokho, i-radar entsha izogcwalisa ‘insimu engenalutho’ eBryan College Station ukusiza umphakathi wendawo ukulungiselela kangcono isimo sezulu esibi.”
Kuhlelwe umcimbi wokusikwa kweribhoni nokunikezelwa kwawo ekuqaleni kwesemester yasekwindla ka-2024, lapho i-radar isisebenza ngokugcwele.
