Kushandiswa kweDoppler Radar muMeteorology
Doppler radar inomiririra imwe yekufambira mberi kukuru kwetekinoroji mumunda wezvemamiriro ekunze. Kukwanisa kwayo kupa zviyero zvakadzama uye zvakarurama zvemamiriro ekunze kwakachinja kufanotaura kwemamiriro ekunze uye kutevera madutu, zvichibatsira pakugadzirira zviri nani uye kuderedza njodzi dzechisikigo. Chinyorwa chino chinoongorora misimboti iri shure kweDoppler radar nemashandisirwo ayo muzvemamiriro ekunze, zvichisimbisa kukosha kwayo mukufanotaura kwemamiriro ekunze kwemazuva ano.
Kunzwisisa Doppler Radar
Kuti tinzwisise kukosha kweDoppler radar pamamiriro ekunze, zvakakosha kunzwisisa misimboti yayo. Masisitimu ekare eradar anoburitsa mafungu eredhiyo anosvetuka kubva pazvinhu odzokera kuantena yeradar, zvichibvumira kuverenga daro uye mepu yenzvimbo yechinhu. Zvisinei, Doppler radar inoenda mberi nekushandisa Doppler effect.
Doppler effect inoreva kuchinja kwemafungu kana marefu ewave kana tichitarisa muoni achifamba zvichienderana nekwakabva mafungu. Mukushandiswa kwemamiriro ekunze, Doppler radar inoshandisa musimboti uyu kuyera kumhanya kwezvikamu zvemvura inonaya. Nekuongorora mafambiro enguva yechiratidzo cheradar chakadzoserwa, nyanzvi dzemamiriro ekunze dzinogona kuona kumhanya nekwakananga zvikamu izvi, dzichipa ruzivo rwakakosha nezvemaitiro emhepo uye simba remhepo.
Historical Development uye Evolution
Pfungwa yeDoppler effect yakatanga kutaurwa nenyanzvi yefizikisi yekuAustria Christian Doppler muna 1842. Zvisinei, kushandiswa kwenheyo iyi mu tekinoroji yeradar kwakatanga panguva yeHondo Yenyika II, kunyanya nekuda kwehondo. Zvakatozotanga kushandiswa mumeteorology kuma1950 nema1960.
Kugadzirwa kweDoppler radar yekufanotaura mamiriro ekunze kwakafambiswa mberi zvakanyanya nechirongwa cheUnited States cheNext Generation Weather Radar (NEXRAD) muma1980 nema1990. NEXRAD, iyo yakaisa network yezviteshi zveDoppler radar muUnited States yese, yakapa vanoongorora mamiriro ekunze ruzivo rwakakura rwenguva chaiyo pamusoro pemamiriro ekunze akaipisisa, zvichivandudza kururama kwekufanotaura uye nguva yekutungamirira.
Kuvandudza Kufanotaura Kwemamiriro Ekunze
Mupiro weDoppler radar mukuongorora mamiriro ekunze unonyanya kuoneka mukufanotaura mamiriro ekunze kwakasimba uye kuongorora. Nekuyera kumhanya kwezvikamu zvemvura inonaya, Doppler radar inogona kuona maitiro ekutenderera mukati memadutu, chiratidzo chikuru chemadutu. Kugona uku kunobvumira vanoongorora mamiriro ekunze kupa yambiro dzemadutu panguva yakakodzera uye yakarurama, zvichigona kuponesa hupenyu nekupa veruzhinji ruzivo rwakakosha rwekuti vadzivirirwe.
Uyezve, Doppler radar inobatsira mukuona nekutevera zvimwe zviitiko zvemamiriro ekunze akaipisisa zvakaita semadutu, mabhanan'ana, uye mafashamo. Nekupa ruzivo rwakadzama nezvekusimba kwemvura uye kufamba kwayo, Doppler radar inogonesa vanoongorora mamiriro ekunze kutarisa kukura kwedutu nekushanduka-shanduka kwaro munguva chaiyo. Kutevera uku panguva chaiyo kwakakosha pakupa yambiro nenguva uye kugadzirira nharaunda njodzi dzemamiriro ekunze dziri kuuya.
Kushandiswa muAviation neMaritime Operations
Kupfuura kufanotaura mamiriro ekunze kwechinyakare, Doppler radar inoita basa rakakosha mukufambisa ndege nemabasa emugungwa. Mukufambisa ndege, Doppler radar inoshandiswa pakuona kuchekwa kwemhepo, chiitiko chine njodzi apo shanduko dzinokurumidza mukumhanya kwemhepo nekwainoenda dzinoitika. Kuchekwa kwemhepo kunogona kukonzera njodzi huru panguva yekusimuka nekumhara kwendege. Nekuona kusiyana uku, Doppler radar inobatsira kuvandudza kudzora kwekufamba kwendege uye kuwedzera kuchengetedzeka kwekubhururuka.
Mukushanda kwegungwa, Doppler radar inobatsira mukutarisa mamiriro egungwa nemamiriro ekunze, zvakakosha pakuona kuchengetedzeka kwezvikepe mugungwa. Inopa ruzivo pamusoro pehurefu hwemafungu, kumhanya kwemhepo, uye kwainoenda, ichibatsira mukufamba uye ichibatsira zvikepe kudzivirira mamiriro ekunze ane njodzi.
Zvitsva uye Tarisiro Yeramangwana
Kufambira mberi muhunyanzvi hweradar yeDoppler kuri kuramba kuchiwedzera kugona kwayo uye mashandisirwo ayo mu meteorology. Radar yeDoppler ine polarization mbiri, semuenzaniso, inoburitsa uye inogamuchira pulses dzakatwasuka nedzakatwasuka, zvichipa ruzivo rwakadzama nezvemhando dzemvura inonaya, dzakadai sekusiyanisa pakati pemvura inonaya, sinou, nechimvuramabwe. Rudzi urwu rwedata rwakawedzerwa runovandudza kufungidzira kwemvura inonaya uye runowedzera kururama kwekufanotaura kwemamiriro ekunze.
Radar yePhased-array imwe tekinoroji iri kubuda inovimbisa kucherechedza mamiriro ekunze nekukurumidza uye kwakanyatsojeka. Kusiyana nemasisitimu ekare eradar anotenderera nekanika kuti atarise mhepo, radar yephased-array inoshandisa maantenna madiki, anodzorwa nemagetsi kuti atungamirire radar nekukurumidza. Kugona uku kunobvumira kucherechedza mamiriro ekunze kakawanda uye kwakazara, zvichigona kuchinja kutarisa mamiriro ekunze anochinja nekukurumidza.
Uyezve, kubatanidza data reDoppler radar nezvimwe zvishandiso zvemamiriro ekunze, zvakaita sekutarisa kwesatellite uye masensa epasi, kunowedzera kunzwisisa kwese kwemasisitimu emamiriro ekunze. Kubatanidza manyuko edata aya mumamodheru emamiriro ekunze akaomarara kunoita kuti vanoongorora mamiriro ekunze vave nemufananidzo wakazara wemamiriro ekunze, zvichikonzera kuvandudzwa kwekufanotaura.
Matambudziko Nezvinogumira
Kunyange zvazvo Doppler radar pasina mubvunzo yakachinja mamiriro ekunze, haina matambudziko ayo nemiganhu yayo. Dambudziko guru idambudziko rekuderedzwa kwemwaradha, uko chiratidzo cheradar chinoderera pachapfuura nepakati pemvura zhinji. Izvi zvinogona kukonzera kusakoshesa simba remvura uye kukanganisa kururama kwekufanotaura kwemamiriro ekunze.
Chimwe chikanganiso ndechekuti radar inogona kupararira zvishoma uye kuti inokwanisa sei kupararira. Kunyange zvazvo radar yeDoppler ichigona kupa ruzivo rwakadzama mukati mechikamu chakati, kururama kwayo kunoderera nedaro. Muganho uyu unonyanya kukosha munzvimbo dziri kure kana dzisina vanhu vakawanda uko radar inogona kunge isina kukwana.
Pamusoro pezvo, kududzirwa kwedata reDoppler radar kunoda kudzidziswa kwakakosha uye hunyanzvi. Kuongorora kumhanya uye maitiro ekuratidzira mumifananidzo yeradar kunogona kuoma, uye vanoongorora mamiriro ekunze vanofanira kugara vachivandudza hunyanzvi hwavo kuti vaenderane nekufambira mberi kwetekinoroji.
mhedziso
Mukupedzisa, Doppler radar yave chishandiso chakakosha mukuongorora mamiriro ekunze kwemazuva ano, ichichinja nzira yatinonzwisisa uye yatinofungidzira mamiriro ekunze. Kubva pakuvandudza kufanotaura kwemamiriro ekunze kwakaoma kusvika pakuvandudza mashandiro endege negungwa, mashandisirwo eDoppler radar akakura uye akasiyana-siyana. Kugona kwayo kupa data renguva chaiyo pamusoro pesimba remvura, maitiro emhepo, uye mafambiro edutu kwakavandudza zvakanyanya kururama uye nguva dzekutungamira kwekufanotaura kwemamiriro ekunze.
Sezvo tekinoroji ichiramba ichifambira mberi, zvinhu zvitsva zvakaita se dual-polarization uye phased-array radar zvinovimbisa kugona kukuru uye kunyatsoongorora mamiriro ekunze. Zvisinei, matambudziko akadai sekuderedzwa kwemwaranzi uye kufukidzwa kushoma anofanirwa kugadziriswa kuti awedzere kugona kwetekinoroji iyi inoshamisa.
Pakupedzisira, kushandiswa kweDoppler radar mukuongorora mamiriro ekunze kunoratidza kukosha kwekutsvagisa kuri kuitwa, kusimudzira, uye kuisa mari muzvirongwa zvemazuva ano zvekutarisa mamiriro ekunze. Nekushandisa kufambira mberi uku, tinogona kugadzirira zviri nani nekuderedza migumisiro yemamiriro ekunze akaipa, kuchengetedza hupenyu nenharaunda pasi rose.
