Nzvimbo yeAggieland ichachinja vhiki rino apo sisitimu itsva yeradar yemamiriro ekunze ichaiswa padenga reEller Oceanography and Meteorology Building yeTexas A&M University.
Kuiswa kweradar itsva iyi kwakakonzerwa nekushanda pamwe chete pakati peClimavision neTexas A&M Department of Atmospheric Sciences kuti vafunge patsva kuti vadzidzi, vadzidzisi nenharaunda vanodzidza sei uye vanopindura sei mumamiriro ekunze.
Radar itsva iyi inotsiva Agi Doppler Radar yekare (ADRAD) iyo yave ichitonga Agilan kubvira pakavakwa Operations and Maintenance Building muna 1973. Kugadziriswa kukuru kwekupedzisira kweADRAD kwakaitika muna 1997.
Kana mamiriro ekunze achibvumira, kubviswa kweADRAD uye kuiswa kweradar itsva kuchaitwa neherikoputa neMugovera.
"Masisitimu eradar emazuva ano akavandudzwa kakawanda nekufamba kwenguva, kusanganisira matekinoroji ekare neatsva," akadaro Dr. Eric Nelson, mubatsiri wepurofesa wesainzi yemhepo. "Kunyange zvazvo zvinhu zvakaita seradiation receiver netransmitter zvakadzorerwa zvakanaka, chatainyanya kunetseka nacho kwaive kutenderera kwadzo padenga rechivako chekushanda. Kushanda kweradar kwakavimbika kwakawedzera kudhura uye kusanzwisisika nekuda kwekusakara. Kunyangwe dzimwe nguva zvichishanda, kuve nechokwadi chekuti mashandiro akarongeka kwakava nyaya yakakosha, uye apo mukana weClimavision wakabuda, zvaive nemusoro."
Sisitimu itsva yeradar iradar yeX-band inopa data repamusoro-soro kupfuura kugona kweS-band yeADRAD. Ine antenna ine 8-foot mukati meradome ine 12-foot, kusiyana kukuru kubva kumaradar ekare asina imba yekudzivirira kubva kumamiriro ekunze akadai semamiriro ekunze, marara uye kukuvara kwemuviri.
Radar itsva iyi inowedzera kugona kwe dual polarization uye kushanda nguva dzose, iri nani zvikuru kupfuura yakatangira. Kusiyana ne single horizontal polarization yeADRAD, dual polarization inobvumira mafungu e radar kufamba mundege dzakatwasuka nedzakatwasuka. Dr. Courtney Schumacher, purofesa wezvesainzi yemuchadenga paTexas A&M University, anotsanangura pfungwa iyi nekuenzanisa nyoka nemadolphin.
"Fungidzira nyoka iri pasi, ichifananidzira kupatsanurana kweradar yekare," akadaro Schumacher. "Mukuenzanisa, radar itsva inoita sedolphin, ichikwanisa kufamba mundege yakatwasuka, zvichibvumira kucherechedzwa muzvikamu zviviri zvakatwasuka uye zvakatwasuka. Kugona uku kunotibvumira kuona mahydrometeor muzvikamu zvina uye kusiyanisa pakati pechando, chando nesinou nechimvuramabwe, uye zvakare kuongorora zvinhu zvakaita sehuwandu nekusimba kwemvura."
Kushanda kwayo nguva dzose kunoreva kuti radar inogona kupa maonero akazara, ane hunyanzvi hwepamusoro pasina chikonzero chekuti vadzidzisi nevadzidzi vatore chikamu, chero bedzi mamiriro ekunze ari pedyo.
"Nzvimbo yeradar yeTexas A&M inoita kuti ive radar yakakosha yekuona zvimwe zvezvinhu zvinonakidza uye dzimwe nguva zvine njodzi mumamiriro ekunze," akadaro Dr. Don Conley, purofesa wesainzi yemhepo kuTexas A&M. "Radar itsva ichapa datasets itsva dzekutsvagisa dzekutsvaga mamiriro ekunze akaipisisa uye ane njodzi, ukuwo ichipawo mikana yekuwedzera kune vadzidzi vepashure pechikoro kuti vaite tsvakiridzo yekutanga vachishandisa data remunharaunda rinokosha."
Kubudirira kweradar itsva kunopfuura dzidzo yepamusoro, kuchivandudza zvakanyanya masevhisi ekufanotaura mamiriro ekunze uye yambiro kune nharaunda dzemuno nekuwedzera kufukidzwa kwenzvimbo uye kuwedzera kururama. Hunyanzvi hwakavandudzwa hwakakosha pakupa yambiro dzemamiriro ekunze dzakarurama uye panguva yakakodzera, kuponesa hupenyu uye kuderedza kukuvara kwezvinhu panguva yezviitiko zvemamiriro ekunze zvakakomba. Bryan College Station, yaimbova munzvimbo ine "radar gap", ichafukidzwa zvizere munzvimbo dzakaderera, zvichiwedzera kugadzirira kweveruzhinji uye kuchengetedzeka.
Ruzivo rweradar ruchawanikwa kune vanobatana neClimavision, vakaita seNational Severe Storms Laboratory, pamwe nevamwe vatengi veClimavision, kusanganisira vezvenhau. Imhaka yekuchinja kuri kuita zvinhu zviviri pakubudirira kwedzidzo uye kuchengetedzeka kwevanhu, Climavision inofarira zvikuru kubatana neTexas A&M kugadzira radar itsva.
"Zvinonakidza kushanda neTexas A&M kuisa radar yedu yemamiriro ekunze kuti tizadze mipata iri mumunda," akadaro Chris Good, CEO weClimavision iri kuLouisville, Kentucky. "Chirongwa ichi hachingowedzere ruzivo rwakakwana rwemayunivhesiti nemakoreji chete, asiwo chinopa vadzidzi ruzivo rwekudzidza ruzivo rwemazuva ano ruchabatsira zvikuru munharaunda dzemuno."
Radar itsva yeClimavision pamwe nekushanda pamwe chete neDhipatimendi reSainzi yeMuchadenga zvinoratidza chiitiko chikuru munhoroondo yakakura yeTexas A&M yetekinoroji yeradar, iyo yakatanga kuma1960 uye yagara iri pamberi mukugadzira zvinhu zvitsva.
"Texas A&M yagara ichiita basa guru mukutsvagisa radar yemamiriro ekunze," akadaro Conley. "Purofesa Aggie akabatsira zvikuru mukuona mafrequency akakodzera uye ma wavelengths ekushandiswa kweradar, vachiisa hwaro hwekufambira mberi munyika yese kubvira kuma1960. Kukosha kweradar kwakaonekwa nekuvakwa kwechivakwa cheBureau of Meteorology muna 1973. Chivako ichi chakagadzirirwa kuchengetedza nekushandisa tekinoroji iyi yakakosha."
Tekinoroji iyi yakagadzira ndangariro dzakanaka kuvadzidzisi veTexas A&M University, vashandi nevadzidzi munhoroondo yese yeradar sezvo yainge yarega basa.
Vadzidzi veTexas A&M University vaishanda neADRAD panguva yeDutu reIke muna 2008 uye vaitumira ruzivo rwakakosha kuNational Weather Service (NWS). Pamusoro pekutarisa data, vadzidzi vakapa kuchengetedzeka kwemuchina kuma radar sezvo madutu aisvika kumahombekombe uye vaitarisawo data rakakosha ringangodiwa neNational Weather Service.
Musi wa21 Kurume, 2022, ADRAD yakapa rubatsiro rwekukurumidzira kuNWS apo ma supercell ekutarisa radar eKGRK Williamson County aisvika kuBrazos Valley akamiswa kwenguva pfupi nekuda kwechimvuramabwe. Yambiro yekutanga yechimvuramabwe yakapihwa husiku ihwohwo yekutevera supercell iri kuchamhembe kweBurleson County yakavakirwa pakuongorora kweADRAD. Zuva rakatevera, madutu manomwe emhepo akasimbiswa munzvimbo yekunyevera yeNWS Houston/Galveston County, uye ADRAD yakaita basa rakakosha mukufanotaura nekunyevera panguva yechiitiko ichi.
Kuburikidza nekushanda pamwe chete kwayo neClimavision, Texas A&M Atmopher Sciences ine chinangwa chekuwedzera zvakanyanya kugona kwehurongwa hwayo hutsva hweradar.
"Radar yeAjiDoppler yakabatsira Texas A&M nenharaunda zvakanaka kwemakumi emakore," akadaro Dr. R. Saravanan, purofesa uye director weDhipatimendi reSainzi yeAtmospheric kuTexas A&M. "Sezvo yava kusvika kumagumo ehupenyu hwayo hunobatsira, tinofara kuumba mubatanidzwa mutsva neClimavision kuti tive nechokwadi chekuti inotsiviwa nenguva. Vadzidzi vedu vachawana ruzivo rweradar rwechizvino-zvino rwedzidzo yavo yezvemamiriro ekunze. "Pamusoro pezvo, radar itsva ichazadza 'nzvimbo isina chinhu' paBryan College Station kubatsira nharaunda yemuno kugadzirira zviri nani mamiriro ekunze akaipa."
Mutambo wekucheka ribhoni nekutsaurira wakarongerwa kutanga kwesemester yemwaka wechirimo wa2024, apo radar inenge yava kushanda zvizere.
