Radar yamkuntho

mphepo yamkuntho radar

Masiku ano, chifukwa cha luso lamakono lomwe limapangidwa tsiku ndi tsiku, munthu amatha kuneneratu zanyengo molondola komanso molondola. Chimodzi mwa zipangizo zamakono zochitira kulosera zanyengo ndi mphepo yamkuntho radar. Monga momwe dzina lake likusonyezera, likhoza kutithandiza kulosera za mtambo wokhuthala komanso wosakhazikika wochititsa mkuntho.

M'nkhaniyi tifotokoza zonse zomwe muyenera kudziwa zokhudza radar yamkuntho, makhalidwe ake ndi zothandiza.

Kodi storm radar ndi chiyani

mphepo yamkuntho pa radar

Radar yamkuntho ndi chida chachikulu chomwe chimakhala ndi nsanja yotalika 5 mpaka 10 mita yokhala ndi dome lozungulira lokutidwa ndi zoyera. Pali zigawo zingapo (tinyanga, masiwichi, ma transmitters, olandila ...) zomwe zimapanga radar ya dome iyi yokha.

Mabwalo a radar omwe amayendetsa amalola kuyerekeza kufalikira ndi kuchuluka kwa mvula, kaya yolimba (chipale chofewa kapena matalala) kapena yamadzimadzi (mvula). Izi ndizofunikira pakuwunika ndi kuyang'anira zanyengo, makamaka m'malo ovuta kwambiri, monga mvula yamkuntho kapena mvula yamkuntho, komwe kumakhala mvula yamphamvu kwambiri komanso yosasunthika, ndiye kuti, mvula yambiri imawunjikana pamalo amodzi. nthawi yochepa.

Momwe Storm Radar Imagwirira Ntchito

mvula

Mfundo yogwiritsira ntchito radar yamkuntho imachokera ku kutuluka kwa cheza cha microwave. Miyendo iyi kapena ma pulse a radiation amayenda mumlengalenga ngati ma lobe angapo. Pamene kugunda kumakumana ndi chopinga, gawo la ma radiation otulutsidwa limabalalika (kumwazikana) kumbali zonse ndipo gawo likuwonekera kumbali zonse. Gawo la ma radiation lomwe limawonekera ndikufalikira molunjika ku radar ndiye chizindikiro chomaliza chomwe mumalandira.

Njirayi imaphatikizapo kuyendetsa ma radiation angapo, choyamba ndikuyika mlongoti wa radar pamalo ena ake okwera. Mlingo wokwera wa mlongoti ukakhazikitsidwa, imayamba kuzungulira. Pamene mlongoti umadzizungulira wokha, umatulutsa ma radiation.

Mlongotiyo ikamaliza ulendo wake, njira yomweyi imachitidwa kuti ikweze mlongoti kumalo enaake, ndi zina zotero, kuti akwaniritse chiwerengero cha ma angles okwera. Umu ndi momwe mumapezera zomwe zimatchedwa polar radar data - seti ya data ya radar yomwe ili pansi komanso kumwamba.

Zotsatira za ndondomeko yonse Imatchedwa scanial scanial ndipo imatenga pafupifupi mphindi 10 kuti ithe. Makhalidwe a ma pulses otulutsidwa ndi ma radiation ndikuti ayenera kukhala amphamvu kwambiri, chifukwa mphamvu zambiri zomwe zimatulutsidwa zimatayika ndipo gawo laling'ono chabe la chizindikiro limalandiridwa.

Kujambula kulikonse kwamlengalenga kumapanga chithunzi, chomwe chiyenera kukonzedwa chisanagwiritsidwe ntchito. Kukonza fanoli kumaphatikizapo kukonza zosiyanasiyana, kuphatikizapo kuchotsedwa kwa malo opangidwa ndi zizindikiro zabodza, ndiko kuti, kuchotsedwa kwa mapiri opangidwa ndi zizindikiro zabodza. Kuchokera pa ndondomeko yonse yomwe tafotokozera pamwambapa, chithunzi chimapangidwa chomwe chikuwonetsa gawo la radar. Reflectivity ndi muyeso wa kukula kwa mphamvu yamagetsi yamagetsi ku radar kuchokera ku dontho lililonse.

Mbiri ndi ntchito zakale

Asanatulukire makina oonera mvula, zolosera zanyengo zinkaŵerengedwa pogwiritsa ntchito masamu, ndipo akatswiri a zanyengo ankatha kugwiritsa ntchito masamu kuti adziŵe zanyengo. M’zaka za m’ma 1940, ma radar ankagwiritsidwa ntchito poonera adani pa Nkhondo Yadziko II; ma radar awa nthawi zambiri amapeza zizindikiro zosadziwika, zomwe tsopano timatcha Yufeng. Nkhondo itatha, asayansi adadziwa bwino chipangizocho ndikuchisintha kukhala chomwe tikudziwa tsopano monga mvula ndi / kapena radar yamvula.

Storm radar ndikusintha kwa meteorology: pamalola mabungwe akuluakulu azanyengo kuti apeze zidziwitso zolosera, Ndipo mukhoza kumvetsetsa pasadakhale mphamvu za mtambo, komanso njira yake ndi mawonekedwe ake. , Mlingo ndi kuthekera koyambitsa mvula.

Kutanthauzira kwa zolosera zomwe radar yamvula ikupereka ndizovuta, chifukwa ngakhale ndikupita patsogolo m'dera la meteorological, radar siyimapereka chidziwitso chakutali, ndipo n'zovuta kudziwa malo enieni a meteorological chandamale. Ichi ndi chinenero cholankhulidwa.

Kuti athe kulosera molondola kwambiri, akatswiri a zanyengo amaphunzira za mayendedwe opita patsogolo. Kuwala kwa dzuŵa kukafika m’mitambo, mafunde a mafunde a electromagnetic amachokera ku radar akusintha, zomwe zimatipangitsa kumvetsetsa mikhalidwe ya mvula yomwe ingachitike.

Ngati kusintha kuli kwabwino, njira zakutsogolo komanso mwayi wamvula udzawonjezeka; mwinamwake, ngati kusintha kuli koipa, kutsogolo kudzatsika ndipo mwayi wa mvula udzachepa. Zidziwitso zonse zochokera ku radar zikatumizidwa ku chithunzi cha pakompyuta, kutsogolo kwa mvula kudzagawidwa molingana ndi mphamvu ya mvula, matalala kapena matalala ... Mitundu yambiri imaperekedwa kuchokera kufiira kupita ku buluu molingana ndi mphamvu ya mvula. .

Kufunika kokonzekera ndege

chithunzi chamkuntho cha radar

Choyambirira kunena ndikuti radar yanyengo ndi chida chowonera, osati chida cholosera, kotero imatiwonetsa momwe mvula imagwa (kusesa) data ikasonkhanitsidwa.

Komabe, powona momwe mvula yambiri imasinthira pakapita nthawi, titha "kulosera" m'tsogolomu: kodi ikhalabe m'malo mwake? Kodi idzasuntha njira yathu? Chofunika kwambiri, kodi tingakonzekere maulendo apandege kuti tipewe madera omwe ali ndi mvula yamkuntho ndi mvula?

Zomwe zimasonkhanitsidwa ndi radar zimaperekedwa m'mawonekedwe osiyanasiyana. Kenako, tifotokoza mbali ziwiri zofunika kwambiri zokonzekera ndege ndikutchulanso zina zomwe amachotsedwanso ku Doppler radar miyeso.

Monga mukuwonera, zida zamkuntho ndizothandiza pakulosera zanyengo ndipo zitha kutithandiza pokonzekera ndege. Ndikukhulupirira kuti ndi chidziwitsochi mutha kuphunzira zambiri za radar yamkuntho ndi mawonekedwe ake.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
