Imiterere y'ikirere cya Aggieland izahinduka muri iyi weekend ubwo hazashyirwamo sisitemu nshya ya radar y'ikirere ku gisenge cy'inyubako ya Eller Oceanography and Meteorology ya Kaminuza ya Texas A&M.
Gushyiramo radar nshya ni umusaruro w'ubufatanye hagati ya Climavision n'ishami rya Texas A&M rishinzwe ubumenyi bw'ikirere kugira ngo batekereze uburyo abanyeshuri, abarimu n'abaturage biga kandi bagakora mu gihe cy'imihindagurikire y'ikirere.
Radar nshya isimbura Radar ya Agi Doppler ishaje (ADRAD) yiganje muri Agilan kuva hubakwa inyubako yo kubungabunga no gukora ibikorwa mu 1973. Ivugururwa rikomeye rya nyuma rya ADRAD ryabaye mu 1997.
Niba ikirere kibyemeye, gukuraho ADRAD no gushyiraho radar nshya bizakorwa hakoreshejwe kajugujugu ku wa Gatandatu.
“Sisitemu za radar zigezweho zagiye zivugururwa kenshi uko igihe cyagiye gihita, harimo ikoranabuhanga rishaje n’irishya,” ibi byavuzwe na Dr. Eric Nelson, umwarimu wungirije mu bumenyi bw’ikirere. “Nubwo ibice nk’icyuma gifata imirasire n’icyuma gitanga amakuru byagaruwe neza, icyo twari duhangayikishijwe cyane ni ukuzunguruka kwabyo ku gisenge cy’inyubako. Imikorere ya radar yizewe yarushijeho guhenda kandi ikaba idasobanutse neza bitewe no kwangirika no kwangirika. Nubwo rimwe na rimwe bikora neza, kwemeza ko imikorere ihoraho yabaye ikibazo cy’ingenzi, kandi iyo amahirwe yo gukoresha Climavision yabonekaga, byari bifite ishingiro.”
Sisitemu nshya ya radar ni radar ya X-band itanga amakuru meza kurusha ubushobozi bwa S-band ya ADRAD. Ifite antene ya metero 2.8 imbere muri radome ya metero 2.8, itandukanye cyane na radar za kera zitari zifite aho zikingira kugira ngo zibarinde ibidukikije nk'ikirere, imyanda n'ibyangiritse.
Radar nshya yongera ubushobozi bwo gutandukanya ibintu bibiri n'imikorere ihoraho, ikaba ari yo itera imbere cyane ugereranyije n'iyabanjirije. Bitandukanye na polarization imwe itambitse ya ADRAD, polarization ebyiri zemerera imiraba ya radar kugenda mu kirere kitambitse n'itambitse. Dr. Courtney Schumacher, umwarimu w'ubumenyi bw'ikirere muri Kaminuza ya Texas A&M, asobanura iki gitekerezo akoresheje ikigereranyo cy'inzoka n'ibifi binini.
Schumacher yagize ati: “Tekereza inzoka iri hasi, igereranya imiterere y’urubura rwa kera. Mu kugereranya, urubura rushya rwitwara nk’urubura, rushobora kugenda mu kirere gihagaze, bigatuma rushobora kwitegereza mu buryo butambitse n’ubuhagaze. Ubu bushobozi budufasha kumenya ikirere mu buryo bune no gutandukanya urubura, urubura n’urubura n’urubura, ndetse no gusuzuma ibintu nk’ingano n’ubukana bw’imvura.”
Gukomeza gukora kwayo bivuze ko radar ishobora gutanga ishusho yuzuye kandi ifite imiterere yo hejuru nta mpamvu y'uko abarimu n'abanyeshuri babigiramo uruhare, igihe cyose sisitemu y'ikirere iri hafi.
“Aho radar ya Texas A&M iherereye bituma iba radar y’ingenzi mu kureba bimwe mu bintu bishimishije kandi rimwe na rimwe biteje akaga,” ibi byavuzwe na Dr. Don Conley, umwarimu w’ubumenyi bw’ikirere muri Texas A&M. “Radar nshya izatanga amakuru mashya y’ubushakashatsi ku bushakashatsi busanzwe bw’ikirere kibi kandi giteje akaga, ndetse inatange andi mahirwe ku banyeshuri biga muri kaminuza yo gukora ubushakashatsi bw’ibanze bakoresheje amakuru y’agaciro yo mu gace batuyemo.”
Ingaruka za radar nshya ntizigarukira mu mashuri makuru, zinoza cyane serivisi zo guhanura ikirere no kuburira abaturage mu gace batuyemo binyuze mu kwagura uburyo bwo gukwirakwiza amakuru no kongera uburyo bwo gutanga amakuru. Ubushobozi bwo kuvugurura ni ingenzi mu gutanga amakuru y’iteganyagihe ku gihe kandi nyacyo, kurokora ubuzima no kugabanya ibyangiritse ku mitungo mu gihe cy’ibiza bikomeye. Sitasiyo ya Bryan College, yahoze iherereye mu gace ka "radar gafite icyuho", izahabwa amakuru yose mu misozi miremire, bikongera imyiteguro n’umutekano by’abaturage.
Amakuru ya radar azashyirwa ku bafatanyabikorwa ba Climavision, nka Laboratwari y'Igihugu y'Inkubi z'Ubwoko, ndetse n'abandi bakiriya ba Climavision, barimo n'itangazamakuru. Kubera ingaruka ebyiri ku bwiza bw'amasomo n'umutekano rusange, Climavision ishishikajwe cyane no gukorana na Texas A&M mu gutegura radar nshya.
“Birashimishije gukorana na Texas A&M kugira ngo dushyireho radar yacu y’ikirere kugira ngo twuzuze icyuho kiri mu kazi,” ibi byavuzwe na Chris Good, Umuyobozi Mukuru wa Climavision yo muri Louisville, muri Kentucky. “Uyu mushinga ntukoresha gusa serivisi zo mu rwego rwo hasi, ahubwo unaha abanyeshuri ubunararibonye bwo kwiga amakuru agezweho azagira ingaruka zikomeye ku baturage.”
Radar nshya ya Climavision n'ubufatanye na Minisiteri y'Ubumenyi bw'Ikirere bigaragaza intambwe ikomeye mu ikoranabuhanga rya radar rya Texas A&M, ryatangiye mu myaka ya za 1960 kandi rihora riri ku isonga mu guhanga udushya.
Conley yagize ati: “Texas A&M imaze igihe kinini igira uruhare runini mu bushakashatsi ku bijyanye na radar y’ikirere. Porofeseri Aggie yagize uruhare runini mu kumenya frequencies nziza n’uburebure bw’umuraba byo gukoresha radar, ashyiraho urufatiro rw’iterambere mu gihugu hose kuva mu myaka ya 1960. Akamaro ka radar kagaragaye ubwo hubakwaga inyubako y’Ibiro by’Ubushakashatsi ku Mirere mu 1973. Inyubako yagenewe kwakira no gukoresha ubu buryo bw’ingenzi.”
Iri koranabuhanga ryatumye abarimu, abakozi n'abanyeshuri ba Kaminuza ya Texas A&M bahora bibuka ibihe byiza mu mateka y'iyi kaminuza ubwo yajyaga mu kiruhuko cy'izabukuru.
Abanyeshuri ba Kaminuza ya Texas A&M bakoreye ADRAD mu gihe cy’inkubi y’umuyaga ya Ike mu 2008 kandi bageza amakuru y’ingenzi kuri Serivisi y’Igihugu ishinzwe Iteganyagihe (NWS). Uretse gukurikirana amakuru, abanyeshuri batanze umutekano wa mekanike kuri radar ubwo inkubi z’umuyaga zegeraga ku nkombe ndetse banakurikirana amakuru y’ingenzi ashobora gukenerwa na Serivisi y’Igihugu ishinzwe Iteganyagihe.
Ku ya 21 Werurwe 2022, ADRAD yatanze ubufasha bwihutirwa kuri NWS ubwo insinga nini zo kugenzura radar za KGRK Williamson County zegeraga mu kibaya cya Brazos zahagarikwaga by'agateganyo n'inkubi y'umuyaga. Umuburo wa mbere w'inkubi y'umuyaga watanzwe muri iryo joro kugira ngo hakurikire insinga nini ku murongo w'Amajyaruguru ya Burleson County washingiye ku isesengura rya ADRAD. Umunsi wakurikiyeho, inkubi zirindwi z'umuyaga zemejwe mu gace k'ububurira ka NWS Houston/Galveston County, kandi ADRAD yagize uruhare runini mu guhanura no gutanga umuburo mu gihe cy'ibyabaye.
Binyuze mu bufatanye bwayo na Climavision, Texas A&M Atmopher Sciences igamije kwagura cyane ubushobozi bwa sisitemu nshya ya radar.
“Radar ya AjiDoppler imaze imyaka ibarirwa muri za mirongo ikora neza muri Texas A&M ndetse no mu baturage,” ibi byavuzwe na Dr. R. Saravanan, umwarimu akaba n'umuyobozi w'ishami ry'ubumenyi bw'ikirere muri Texas A&M. “Mu gihe yegereje iherezo ry'ubuzima bwayo bw'ingirakamaro, twishimiye gukorana ubufatanye bushya na Climavision kugira ngo twizere ko izasimburwa ku gihe. Abanyeshuri bacu bazabona amakuru agezweho ya radar mu burezi bwabo ku bijyanye n'ikirere. “Byongeye kandi, radar nshya izuzura ‘ahantu hatari ikintu’ kuri sitasiyo ya Bryan College kugira ngo ifashe abaturage bo muri ako gace kwitegura neza ikirere kibi.”
Hateganijwe umuhango wo gukata no kwegurira Imana mu ntangiriro z'igihembwe cy'umuhindo cya 2024, ubwo radar izaba yuzuye.
