Mzere wa mlengalenga wa ku Aggieland usintha kumapeto kwa sabata ino pamene makina atsopano owunikira nyengo adzayikidwa padenga la nyumba ya Texas A&M University ya Eller Oceanography and Meteorology.
Kukhazikitsa radar yatsopanoyi ndi zotsatira za mgwirizano pakati pa Climavision ndi Texas A&M Department of Atmospheric Sciences kuti aganizirenso momwe ophunzira, aphunzitsi ndi anthu ammudzi amaphunzirira ndikuyankha nyengo.
Radar yatsopanoyi ilowa m'malo mwa Agi Doppler Radar yakale (ADRAD) yomwe yakhala ikulamulira Agilan kuyambira pomwe Nyumba Yogwirira Ntchito ndi Kukonza idamangidwa mu 1973. Kusintha kwakukulu komaliza kwa ADRAD kunachitika mu 1997.
Ngati nyengo ilola, kuchotsa ADRAD ndi kukhazikitsa radar yatsopano kudzachitika pogwiritsa ntchito helikopita Loweruka.
“Makompyuta amakono a radar asinthidwa kwambiri pakapita nthawi, kuphatikizapo ukadaulo wakale ndi watsopano,” anatero Dr. Eric Nelson, pulofesa wothandizira wa sayansi ya mlengalenga. “Ngakhale kuti zida monga cholandirira ma radiation ndi transmitter zinabwezeretsedwa bwino, nkhawa yathu yayikulu inali kuzungulira kwawo kwamakina padenga la nyumba yogwirira ntchito. Kugwira ntchito kwa radar kodalirika kunakhala kokwera mtengo kwambiri komanso kosatsimikizika chifukwa cha kuwonongeka. Ngakhale nthawi zina kugwira ntchito bwino, kuonetsetsa kuti magwiridwe antchito nthawi zonse anakhala nkhani yofunika kwambiri, ndipo pamene mwayi wa Climavision unabwera, zinali zomveka.”
Dongosolo latsopano la radar ndi radar ya X-band yomwe imapereka deta yolondola kwambiri kuposa mphamvu ya ADRAD ya S-band. Ili ndi antenna ya mamita 8 mkati mwa radome ya mamita 12, kusiyana kwakukulu ndi ma radar akale omwe analibe malo otetezera ku zinthu zachilengedwe monga nyengo, zinyalala ndi kuwonongeka kwakuthupi.
Radar yatsopanoyi imawonjezera mphamvu ziwiri zolumikizirana ndi ma polarization komanso kugwira ntchito kosalekeza, kusintha kwakukulu kuposa komwe kunayamba kale. Mosiyana ndi ADRAD's single horizontal polarization, dual polarization imalola mafunde a radar kuyenda m'malo opingasa komanso opingasa. Dr. Courtney Schumacher, pulofesa wa sayansi ya mlengalenga ku Texas A&M University, akufotokoza lingaliro ili ndi fanizo la njoka ndi ma dolphin.
"Tangoganizirani njoka pansi, yomwe ikuyimira kugawanika kwa radar yakale," adatero Schumacher. "Poyerekeza, radar yatsopanoyi imachita zinthu ngati dolphin, yomwe imatha kuyenda molunjika, zomwe zimathandiza kuti tiwone bwino m'magawo opingasa komanso opingasa. Mphamvu imeneyi imatithandiza kuzindikira ma hydrometeor m'magawo anayi ndikusiyanitsa pakati pa ayezi, matalala ndi chipale chofewa, komanso kuwunika zinthu monga kuchuluka ndi mphamvu ya mvula."
Kugwira ntchito kwake kosalekeza kumatanthauza kuti radar ikhoza kupereka chithunzi chokwanira komanso chowoneka bwino popanda kufunikira kwa aphunzitsi ndi ophunzira kutenga nawo mbali, bola ngati nyengo ili pafupi.
"Malo omwe radar ya Texas A&M ili ndi radar yofunika kwambiri poona zochitika zina zosangalatsa komanso nthawi zina zoopsa za nyengo," anatero Dr. Don Conley, pulofesa wa sayansi ya mlengalenga ku Texas A&M. "Radar yatsopanoyi ipereka deta yatsopano yofufuzira kafukufuku wachikhalidwe woopsa komanso woopsa, komanso ipereka mwayi wowonjezera kwa ophunzira a digiri yoyamba kuti achite kafukufuku woyambirira pogwiritsa ntchito deta yamtengo wapatali yakomweko."
Mphamvu ya radar yatsopanoyi ikupita patsogolo kuposa maphunziro apamwamba, ikukweza kwambiri ntchito zolosera nyengo ndi machenjezo kwa anthu am'deralo mwa kukulitsa kufalikira kwa nkhani ndikuwonjezera kulondola. Mphamvu zokwezedwa ndizofunikira kwambiri popereka machenjezo a nyengo panthawi yake komanso molondola, kupulumutsa miyoyo ndikuchepetsa kuwonongeka kwa katundu panthawi yamavuto a nyengo. Bryan College Station, yomwe kale inali pamalo opanda radar, idzalandira chithandizo chonse pamalo otsika, zomwe zikuwonjezera kukonzekera kwa anthu onse komanso chitetezo.
Deta ya radar idzaperekedwa kwa ogwirizana nawo a boma la Climavision, monga National Severe Storms Laboratory, komanso makasitomala ena a Climavision, kuphatikizapo atolankhani. Chifukwa cha kusinthasintha kwa maphunziro ndi chitetezo cha anthu, Climavision ili ndi chidwi chachikulu chogwirizana ndi Texas A&M kuti ipange radar yatsopanoyi.
"Ndizosangalatsa kugwira ntchito ndi Texas A&M kuti tiike radar yathu ya nyengo kuti tikwaniritse mipata m'munda," adatero Chris Good, CEO wa Climavision yomwe ili ku Louisville, Kentucky. "Pulojekitiyi sikuti imangokulitsa maphunziro apansi pa yunivesite ndi makoleji, komanso imapatsa ophunzira chidziwitso chogwira ntchito pophunzira deta yapamwamba yomwe ingathandize kwambiri madera am'deralo."
Rada yatsopano ya Climavision ndi mgwirizano ndi Dipatimenti ya Sayansi ya Mlengalenga ndi chizindikiro cha mbiri yakale mu mbiri yakale ya ukadaulo wa rada wa Texas A&M, womwe unayamba m'ma 1960 ndipo nthawi zonse wakhala patsogolo pa zatsopano.
“Texas A&M yakhala ikugwira ntchito yotsogola pa kafukufuku wa radar ya nyengo,” anatero Conley. “Pulofesa Aggie anali wofunikira kwambiri pozindikira ma frequency ndi ma wavelength abwino kwambiri ogwiritsira ntchito radar, zomwe zinakhazikitsa maziko a kupita patsogolo mdziko lonse kuyambira m'ma 1960. Kufunika kwa radar kunaonekera pamene nyumba ya Bureau of Meteorology inamangidwa mu 1973. Nyumbayi idapangidwa kuti ikhale ndi ukadaulo wofunikirawu.”
Ukadaulo uwu unapanga zokumbukira zabwino kwa aphunzitsi, antchito ndi ophunzira a ku Texas A&M University m'mbiri yonse ya radar pamene idapuma pantchito.
Ophunzira a ku Texas A&M University ankayendetsa ndege za ADRAD panthawi ya mphepo yamkuntho ya Ike mu 2008 ndipo ankatumiza uthenga wofunikira ku National Weather Service (NWS). Kuwonjezera pa kuyang'anira deta, ophunzirawo anapereka chitetezo cha makina ku ma radar pamene mphepo yamkuntho inkayandikira gombe komanso ankayang'anira deta yofunika kwambiri yomwe ingafunike ndi National Weather Service.
Pa 21 Marichi, 2022, ADRAD idapereka thandizo ladzidzidzi ku NWS pamene ma supercell oyang'anira radar a KGRK Williamson County omwe anali pafupi ndi Brazos Valley adayimitsidwa kwakanthawi ndi chimphepo chamkuntho. Chenjezo loyamba la chimphepo chamkuntho lomwe linaperekedwa usiku womwewo kuti litsatire supercell yomwe ili kumpoto kwa Burleson County linachokera ku kusanthula kwa ADRAD. Tsiku lotsatira, zimphepo zamkuntho zisanu ndi ziwiri zinatsimikizika m'dera la chenjezo la NWS Houston/Galveston County, ndipo ADRAD idachita gawo lofunikira pakulosera ndi kuchenjeza panthawi ya chochitikachi.
Kudzera mu mgwirizano wake ndi Climavision, Texas A&M Atmopher Sciences cholinga chake ndi kukulitsa kwambiri mphamvu za makina ake atsopano a radar.
“Rada ya AjiDoppler yathandiza bwino Texas A&M ndi anthu ammudzi kwa zaka zambiri,” anatero Dr. R. Saravanan, pulofesa komanso director wa Dipatimenti ya Sayansi ya Mlengalenga ku Texas A&M. “Pamene ikuyandikira mapeto a moyo wake wothandiza, tikusangalala kupanga mgwirizano watsopano ndi Climavision kuti titsimikizire kuti ilowa m'malo mwake panthawi yake. Ophunzira athu adzakhala ndi mwayi wopeza deta yaposachedwa ya rada yophunzitsira za nyengo. “Kuphatikiza apo, rada yatsopanoyi idzadzaza 'munda wopanda kanthu' ku Bryan College Station kuti ithandize anthu ammudzi kukonzekera bwino nyengo yoipa.”
Mwambo wodula riboni ndi kupatsa anthu ntchito ukukonzekera kuyamba kwa semesita ya autumn 2024, pomwe radar ikugwira ntchito mokwanira.
