Lub skyline Aggieland yuav hloov lub asthiv no thaum huab cua tshiab radar nruab rau ntawm lub ru tsev ntawm Texas A&M University's Eller Oceanography thiab Meteorology Building.
Kev teeb tsa lub radar tshiab yog qhov tshwm sim ntawm kev sib koom tes ntawm Climavision thiab Texas A&M Department of Atmospheric Sciences kom rov xav txog seb cov tub ntxhais kawm, kws qhia ntawv thiab cov zej zog kawm li cas thiab teb rau huab cua.
Lub radar tshiab hloov lub hnub nyoog Agi Doppler Radar (ADRAD) uas tau tswj hwm Agilan txij li kev tsim kho ntawm Kev Ua Haujlwm thiab Kev Kho Vaj Tse hauv xyoo 1973. Qhov kev hloov tshiab loj kawg ntawm ADRAD tau tshwm sim xyoo 1997.
Huab cua tso cai, tshem tawm ADRAD thiab teeb tsa lub radar tshiab yuav tshwm sim siv lub nyoob hoom qav taub rau hnub Saturday.
"Lub tshuab radar niaj hnub tau hloov kho ntau lub sijhawm, suav nrog cov thev naus laus zis qub thiab tshiab," said Dr. Eric Nelson, tus pab xibfwb ntawm huab cua sciences. "Txawm hais tias cov khoom siv xws li cov khoom siv hluav taws xob thiab cov khoom xa tawm tau zoo rov qab los, peb qhov kev txhawj xeeb tseem ceeb yog lawv cov kev sib hloov ntawm lub ru tsev ntawm lub tsev ua haujlwm. Kev lag luam radar ntseeg tau nce zuj zus thiab tsis paub meej vim qhov hnav thiab tsim kua muag. Txawm hais tias qee zaum ua haujlwm, kev ua haujlwm zoo ib yam yog qhov tseem ceeb, thiab thaum lub sijhawm rau Climavision tshwm sim, nws ua rau muaj kev nkag siab zoo. "
Qhov tshiab radar system yog X-band radar uas muab cov ntaub ntawv daws teeb meem siab dua li ADRAD's S-band peev xwm. Nws nta lub kav hlau txais xov 8-ko taw hauv 12-ko taw radome, qhov tseem ceeb tawm ntawm cov radars qub uas tsis muaj vaj tse tiv thaiv los tiv thaiv lawv ntawm ib puag ncig xws li huab cua, khib nyiab thiab lub cev puas tsuaj.
Tus tshiab radar ntxiv dual polarization muaj peev xwm thiab kev ua haujlwm tas mus li, qhov kev txhim kho tseem ceeb tshaj nws cov thawj coj. Tsis zoo li ADRAD ib leeg kab rov tav polarization, dual polarization tso cai rau radar nthwv dej taug kev hauv ob lub dav hlau kab rov tav thiab ntsug. Dr. Courtney Schumacher, tus xibfwb ntawm atmospheric sciences ntawm Texas A&M University, piav qhia txog lub tswvyim no nrog kev sib piv rau cov nab thiab ntses ntses.
Schumacher tau hais tias "Xav txog tus nab nyob hauv av, ua cim kab rov tav polarization ntawm lub qub radar," Schumacher hais. "Hauv kev sib piv, lub radar tshiab coj tus cwj pwm zoo li tus ntses taub ntswg ntev, tuaj yeem txav mus rau hauv lub dav hlau ntsug, tso cai rau kev soj ntsuam hauv ob qho tib si kab rov tav thiab ntsug. Qhov peev xwm no tso cai rau peb txhawm rau txheeb xyuas hydrometeors hauv plaub qhov loj thiab paub qhov txawv ntawm cov dej khov, dej hiav txwv thiab daus.
Nws txoj haujlwm tas mus li txhais tau hais tias lub radar tuaj yeem muab qhov ua tiav tiav, kev daws teeb meem siab dua yam tsis tas yuav tsum muaj cov kws qhia ntawv thiab cov tub ntxhais kawm koom nrog, tsuav yog huab cua nyob hauv ntau yam.
"Qhov chaw ntawm Texas A&M radar ua rau nws yog ib qho tseem ceeb radar rau kev soj ntsuam qee qhov kev nthuav dav tshaj plaws thiab qee zaum muaj xwm txheej huab cua txaus ntshai," said Dr. Don Conley, tus xibfwb ntawm atmospheric sciences ntawm Texas A&M. "Lub radar tshiab yuav muab cov ntaub ntawv tshawb fawb tshiab rau kev tshawb fawb huab cua hnyav thiab txaus ntshai, thaum tseem muab sijhawm ntxiv rau cov tub ntxhais kawm ntawv qib siab los ua kev tshawb fawb pib siv cov ntaub ntawv tseem ceeb hauv zos."
Qhov tshiab radar qhov cuam tshuam txuas ntxiv mus dhau qhov kev kawm, txhim kho huab cua huab cua thiab kev pabcuam ceeb toom rau cov zej zog hauv zej zog los ntawm kev nthuav dav thiab ua kom raug. Cov peev txheej kho dua tshiab yog qhov tseem ceeb rau kev tshaj tawm cov lus ceeb toom huab cua raws sijhawm thiab raug, txuag lub neej thiab txo cov khoom puas tsuaj thaum muaj huab cua hnyav. Bryan College Chaw Nres Tsheb, yav dhau los nyob hauv thaj chaw "radar gap", yuav tau txais kev pabcuam tag nrho ntawm qhov siab qis, nce kev npaj rau pej xeem thiab kev nyab xeeb.
Cov ntaub ntawv radar yuav muaj rau Climavision tsoomfwv cov koom tes, xws li National Severe Storms Laboratory, nrog rau lwm cov neeg siv Climavision, suav nrog cov xov xwm. Nws yog vim muaj kev cuam tshuam ob qho tib si rau kev kawm zoo thiab kev nyab xeeb rau pej xeem uas Climavision txaus siab rau kev koom tes nrog Texas A&M los tsim lub radar tshiab.
Chris Good, CEO ntawm Louisville, Kentucky-based Climavision hais tias "Nws zoo siab heev los ua haujlwm nrog Texas A&M txhawm rau txhim kho peb cov huab cua radar los ua qhov khoob hauv thaj chaw," said Chris Good, CEO ntawm Louisville, Kentucky-based Climavision. "Qhov project no tsis yog tsuas yog nthuav dav cov kev pab cuam qis qis xwb. tsev kawm ntawv qib siab thiab tsev kawm qib siab, tab sis kuj muab cov tub ntxhais kawm nrog kev paub txog kev paub txog cov ntaub ntawv tshiab uas yuav muaj kev cuam tshuam tiag tiag rau cov zej zog hauv zos."
Tus tshiab Climavision radar thiab kev koom tes nrog Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Kev Tshawb Fawb yog qhov tseem ceeb hauv Texas A&M cov keeb kwm nplua nuj ntawm radar thev naus laus zis, uas rov qab mus rau xyoo 1960 thiab ib txwm nyob ntawm qhov tseem ceeb ntawm kev tsim kho tshiab.
Conley tau hais tias "Texas A&M tau ua lub luag haujlwm ntev ntev hauv kev tshawb fawb huab cua radar," Conley tau hais. "Xib Fwb Aggie yog qhov tseem ceeb hauv kev txheeb xyuas qhov zoo tshaj plaws zaus thiab wavelengths rau kev siv radar, tso lub hauv paus rau kev nce qib thoob plaws hauv lub tebchaws txij li xyoo 1960s. Qhov tseem ceeb ntawm radar tau pom tseeb nrog kev tsim kho ntawm Bureau of Meteorology lub tsev hauv xyoo 1973. Lub tsev yog tsim los rau tsev thiab siv cov cuab yeej tseem ceeb no. "
Cov thev naus laus zis no tsim kev nco zoo rau Texas A&M University cov kws qhia ntawv, cov neeg ua haujlwm thiab cov tub ntxhais kawm thoob plaws lub radar keeb kwm thaum nws so haujlwm.
Texas A&M University cov tub ntxhais kawm ua haujlwm ADRAD thaum muaj nag xob nag cua Ike xyoo 2008 thiab xa cov ntaub ntawv tseem ceeb rau National Weather Service (NWS). Ntxiv nrog rau kev saib xyuas cov ntaub ntawv, cov tub ntxhais kawm muab kev nyab xeeb rau radars thaum nag xob nag cua tuaj txog ntawm ntug dej hiav txwv thiab tseem saib xyuas cov ntaub ntawv tseem ceeb uas yuav xav tau los ntawm National Weather Service.
Thaum Lub Peb Hlis 21, 2022, ADRAD tau muab kev pabcuam thaum muaj xwm txheej ceev rau NWS thaum KGRK Williamson County radar saib xyuas supercells mus txog Brazos Valley raug kaw ib ntus los ntawm cua daj cua dub. Thawj qhov kev ceeb toom cua daj cua dub tau tshaj tawm hmo ntawd kom taug qab lub supercell nyob rau sab qaum teb Burleson County kab yog raws li kev tshuaj xyuas ADRAD. Hnub tom qab, xya lub cua daj cua dub tau lees paub hauv NWS Houston/Galveston County cheeb tsam ceeb toom, thiab ADRAD tau ua lub luag haujlwm tseem ceeb hauv kev kwv yees thiab ceeb toom thaum lub sijhawm tshwm sim.
Los ntawm nws txoj kev koom tes nrog Climavision, Texas A&M Atmopher Sciences aims kom nthuav dav lub peev xwm ntawm nws cov radar tshiab.
"AjiDoppler radar tau ua haujlwm rau Texas A&M thiab cov zej zog zoo tau ntau xyoo," said Dr. R. Saravanan, tus xibfwb thiab tus thawj coj ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb ntawm Texas A&M. "Thaum nws mus txog qhov kawg ntawm nws lub neej muaj txiaj ntsig, peb txaus siab los tsim kev koom tes tshiab nrog Climavision los xyuas kom muaj kev hloov pauv raws sijhawm. Peb cov tub ntxhais kawm yuav tau txais cov ntaub ntawv radar tshiab rau lawv cov kev kawm huab cua. "Ntxiv rau, radar tshiab yuav ua rau 'dawb teb' ntawm Bryan College Chaw Nres Tsheb los pab cov zej zog hauv zos npaj rau huab cua hnyav. "
Lub ribbon txiav thiab kev txiav txim siab ceremony yog npaj rau thaum pib ntawm lub caij nplooj zeeg 2024 semester, thaum lub radar ua hauj lwm tag nrho.
