I tēnei wā o te kaha haere o te huringa āhuarangi, ko ngā ine taumata wai tuku iho ka ine i te "teitei" anake, pērā i te ine i te roa o te tangata, ko te radar wai ia a Doppler ka whakarongo ki te "mamae o te ngākau o te wai" - e whakarato ana i ngā māramatanga toru-ahu onge mō te whakahaere waipuke me te whakahaere rauemi wai.
I te wā waipuke, ko te mea nui e tika ana kia mōhio tātou ehara i te mea ko "te teitei o te wai" engari ko "te tere o te rere." He rite ngā pūoko taumata wai tuku iho ki ngā rūri wahangu, e tuhi ana i ngā huringa tau poutū anake, ko ngā radar waiora Doppler ia e mahi ana pērā i te kaitirotiro e matatau ana ki te reo wai, e whakamārama ana i te hohonutanga o te wai me te tere o te rere, e whakapai ake ana i ngā raraunga kotahi-ahu ki ngā māramatanga ā-wāhi-wā-ahu-whā.
Makutu Ahupūngao: Ina Tūtaki ngā Ngaru Radar ki te Wai Rere
Ko te kaupapa matua o tēnei hangarau i ahu mai i te āhuatanga ā-tinana i kitea i te tau 1842 e te kaipūtaiao Austrian, a Christian Doppler—te Pānga Doppler. Ko te wheako mōhiotia o te tangi o te waka tūroro e piki ana i te tangi i a ia e whakatata mai ana, me te heke iho i a ia e hoki whakamuri ana, koinei te putanga oro o tēnei pānga.
Ina pā ngā ngaru radar ki ngā mata wai e rere ana, ka puta he kōrero ā-tinana tika:
- Te Kitenga Tere: Ka whakaatahia ngā ngaru radar e ngā matūriki iri me ngā hanganga pōrearea i roto i te rere o te wai, ka puta he panonitanga auau. Mā te ine i tēnei "panonitanga auau," ka tatau tika te pūnaha i te tere rere o te mata.
- Te Ine i te Taumata Wai: I te wā kotahi, ka ine te radar i te wā haere o te hihi hei tiki tika i te teitei o te taumata wai
- Tātai Rere: I te whakakotahitanga me ngā tauira āhuahanga whakawhiti-wāhanga (i whiwhihia mā te rangahau-mua, mā te matawai laser rānei i ngā āhua awa/awa), ka tātaihia e te pūnaha te tere rere whakawhiti-wāhanga (mita pūtoru/hēkona) i te wā tūturu.
Te Aranga Hangarau: Mai i te Ine Pūwāhi ki te Māramatanga Pūnaha
1. Aroturukitanga Kore-Papa
- I tāutahia kia 2-10 mita i runga ake i te mata o te wai, kia kore ai e pā kino ki te waipuke
- Kāore he wāhanga i roto i te wai, kāore e pāngia e te paru, te hukapapa, ngā mea ora wai rānei
- Te mahi pumau ahakoa ngā waipuke nui me ngā paru e rere ana
2. Ngā Ahu Raraunga Kāore i Oti
- Ko ngā tikanga tuku iho me tāuta motuhake ngā ine taumata wai me ngā mita rere, me te whakauru raraunga ā-ringa.
- Ka whakaratohia e te radar Doppler ngā awa raraunga wā-tūturu kua whakauruhia:
- Te tika o te taumata wai: ±3 mm
- Te tika o te tere rere: ±0.01 m/s
- Te tika o te rere o te rere: pai ake i te ±5% (i muri i te whakatikatika mara)
3. Ngā Pūnaha Whakatūpato Waipuke Atamai
I roto i te kaupapa "Rūma mō te Awa" a Netherlands, i tutuki i ngā whatunga radar Doppler ngā matapae tika mō ngā tihi waipuke 3-6 hāora i mua. Ehara i te mea ko "te teitei o te wai" anake te matapae a te pūnaha engari ko "te wā e tae atu ai te waipuke ki ngā tāone o raro," ka whiwhi i te wā nui mō te whakawātea me te whakawātea.
Ngā Horopaki Taupānga: Mai i ngā Awa Maunga ki ngā Awa Tāone
Te Arotautanga o te Whare Hiko Waiohiko
Ka whakamahia e ngā tipu hiko wai i ngā Alps o Huiterangi te radar Doppler mō te aroturuki i te rerenga mai o te hiko i te wā tūturu, me te whakarerekē i ngā mahere whakaputa hiko. E whakaatu ana ngā raraunga o te tau 2022, nā te matapae tika o te rerenga hukarere rewa, i whakapiki ake tētahi tipu hiko i te whakaputanga hiko ia tau mā te 4.2%, he rite ki te whakaiti i te 2000 tana o ngā tukunga CO₂.
Te Whakahaere i te Pūnaha Waikeri o te Tāone
I whakatūria e te Rohe Tāone nui o Tōkyō te 87 o ngā pūwāhi aroturuki Doppler, ā, koinei te whatunga radar wai o te tāone nui rawa atu o te ao. Ka tautuhia e te pūnaha ngā aukati waikeri i te wā tonu, ā, ka whakarerekē aunoa i ngā kēti waikeri i te wā ua, ā, ka ārai angitu i ngā waipuke nui e 3 i te tau 2023.
Te Whakaritenga Whakamakuku Ahuwhenua Tika
Ka honoa e ngā rohe whakamakuku o Central Valley o California te radar Doppler me ngā pūoko makuku oneone hei whakatutuki i te whakamakuku atamai "tohatoha rere". Ka whakarerekētia e te pūnaha ngā whakatuwheratanga o te keti wai i runga i ngā tere rere wā-tūturu, ka penapenahia he 37 miriona mita kūpiko o te wai i te tau 2023.
Aroturuki Rere Taiao
I roto i te kaupapa whakaora rauropi o te Awa o Colorado, ka aroturuki tonu te radar Doppler i ngā rerenga rauropi iti rawa mō te hekenga o ngā ika. Ina heke te rerenga ki raro i ngā paepae, ka whakarerekē aunoa te pūnaha i ngā tukunga o te awa ki runga, ā, ka angitu te tiaki i te wā whakaputa uri o te puni ika e tata ana ki te ngaro i te wā o te tau 2022.
Te Whanaketanga Hangarau: Mai i ngā Pūwāhi Takitahi ki te Maramarama Whatunga
E toru ngā huarahi e whanake ana ngā pūnaha radar wai Doppler o te whakatupuranga hou:
- Te Mātauranga Whatunga: He maha ngā pūnga radar e hanga ana i ngā "whatunga io wai" tauine-awa mā te whatunga 5G/Mesh, e whai ana i te horapa o ngā ngaru waipuke mā roto i ngā puna wai.
- Tātari Whakarei Ake i te AI: Ka tautuhia e ngā rauropi ako mīhini ngā hanganga rere (pēnei i ngā awhiowhio, ngā rere tuarua) mai i ngā ira Doppler, ka whakarato i ngā tauira tohatoha tere tika ake.
- Te Hononga Maha-Pūoko: Mā te whakaurunga ki te radar huarere, ngā ine ua, me ngā raraunga amiorangi ka hangaia he pūnaha aroturuki wai atamai "whakaurua ki te rangi-ātea-whenua".
Ngā Wero me te Anamata: Ina Tūtaki te Hangarau ki te Uauatanga Taiao
Ahakoa te whanaketanga o te hangarau, kei te pā tonu ngā wero taiao ki te radar wai Doppler:
- Tērā pea ka pāngia te kounga o te tohu e te wai tino pōuri me te nui o ngā kukū o te paru kua taurite
- Me whai rauropi tukatuka tohu motuhake ngā mata kua kapi i ngā otaota wai
- Me whai aratau ine rere e rua-wāhanga motuhake ngā rerenga wai hukapapa-wai whakaranu
Kei te whakawhanakehia e ngā tīma R&D o te ao:
- Ngā pūnaha radar maha-roopu (Ku-roopu me C-roopu) e urutau ana ki ngā āhuatanga kounga wai rerekē.
- Te hangarau Polarimetric Doppler e wehewehe ana i ngā ngaru mata mai i ngā tere rere o raro i te wai
- Mā ngā kōwae rorohiko taha ka whakaoti i te tukatuka tohu uaua i te pito o te pūrere, ka whakaitihia ngā hiahia tuku raraunga.
Whakatau: Mai i te Aroturukitanga ki te Māramatanga, Mai i te Raraunga ki te Mātauranga
Ehara i te mea ko te whanaketanga o ngā taputapu ine anake te tohu a te radar wai Doppler engari he panonitanga whakaaro anō hoki—mai i te tirohanga ki te wai hei "mea hei ine" ki te mārama ki a ia hei "pūnaha ora me ngā whanonga uaua." Mā tēnei ka kitea ngā rerenga e kore e kitea, ā, ka tika hoki ngā matapae wai koretake.
I tēnei wā, he maha ngā āhuatanga wai tino kino o te ao, kei te huri tēnei hangarau hei huarahi nui mō te noho tahi pai o te tangata me te wai. Ko ia nekehanga auau kua hopukina, ko ia huinga raraunga tere-taumata wai kua whakaputaina, e tohu ana i te ngana ki te mārama o te tangata ki te whakamārama i te reo tūturu.
A te wā ka kite koe i tētahi awa, kia mahara: kei runga ake i te mata o te wai, kei te whakahaerehia e ngā ngaru radar ngaro ngā miriona "kōrero" ia hēkona me te wai e rere ana. Ko ngā hua o ēnei kōrero kei te āwhina i a tātou ki te hanga i tētahi heke mai haumaru ake, pumau ake mō te wai.
He huinga katoa o ngā tūmau me te pūmanawa ahokore, e tautoko ana i te RS485 GPRS /4g/WIFI/LORA/LORAWAN
