Besikala isivinini somoya sisebenzisa ama-anemometer amakhulu eminyaka, kodwa ukuthuthuka kwakamuva kwenze kwaba nokwenzeka ukuhlinzeka ngezibikezelo zesimo sezulu ezithembeke kakhulu nezinembe kakhulu. Ama-anemometer e-Sonic akala isivinini somoya ngokushesha nangokunembile uma kuqhathaniswa nezinguqulo ezivamile.
Izikhungo zesayensi ye-atmospheric ngokuvamile zisebenzisa lezi zixhobo lapho zenza izilinganiso ezijwayelekile noma izifundo ezinemininingwane ukuze zisize ukwenza izibikezelo zesimo sezulu ezinembile zezindawo ezihlukahlukene. Izimo ezithile zemvelo zinganciphisa izilinganiso, kodwa ukulungiswa okuthile kungenziwa ukuze kunqotshwe lezi zinkinga.
Ama-anemometers avele ngekhulu le-15 futhi aqhubekile nokuthuthukiswa nokuthuthukiswa eminyakeni yamuva. Ama-anemometer endabuko, aqala ukuthuthukiswa phakathi nekhulu le-19, asebenzisa ukuhlelwa okuyindilinga kwezinkomishi zomoya ezixhunywe kusilori sedatha. Ngawo-1920, baba bathathu, banikeza impendulo esheshayo, engaguquki esiza ukukala ukushaywa komoya. Ama-anemometer e-Sonic manje ayisinyathelo esilandelayo sokubikezela isimo sezulu, ahlinzeka ngokunemba okukhulu nokuxazulula.
Ama-anemometer e-Sonic, athuthukiswa ngeminyaka yawo-1970s, asebenzisa amaza e-ultrasonic ukuze alinganise ngokushesha isivinini somoya futhi anqume ukuthi amaza omsindo ahamba phakathi kwepheya lezinzwa ayasheshiswa yini noma ehliswa umoya.
Manje sezenziwe kabanzi futhi zisetshenziswa ngezinhloso nezindawo ezahlukahlukene. Ama-anemometer e-sonic anezinhlangothi ezimbili (isivinini somoya nesiqondiso) asetshenziswa kakhulu eziteshini zesimo sezulu, ukuthutha, izinjini zomoya, izindiza, ngisho naphakathi nolwandle, ezintanta kuma-buoys sezulu.
Ama-anemometer e-Sonic angenza izilinganiso ngokulungiswa kwesikhathi okuphezulu kakhulu, ngokuvamile ukusuka ku-20 Hz kuya ku-100 Hz, okuwenza afanelekele ukukalwa kwesiphithiphithi. Izivinini nokulungiswa kulawa mabanga kuvumela izilinganiso ezinembe kakhudlwana. I-sonic anemometer ingelinye lamathuluzi e-meteorological amasha kakhulu eziteshini zesimo sezulu namuhla, futhi ibaluleke kakhulu kune-vane yomoya, ekala ukuqondiswa komoya.
Ngokungafani nezinguqulo zendabuko, i-sonic anemometer ayidingi izingxenye ezihambayo ukuze zisebenze. Bakala isikhathi esisithathayo ukuze ukushaya kwenhliziyo kuhambe phakathi kwezinzwa ezimbili. Isikhathi sinqunywa ibanga phakathi kwalezi zinzwa, lapho isivinini somsindo sincike ekushiseni, ukucindezela kanye nokungcola komoya okunjengokungcola, usawoti, uthuli noma inkungu emoyeni.
Ukuze uthole ulwazi lwesivinini somoya phakathi kwezinzwa, inzwa ngayinye ishintshana njenge-transmitter nomamukeli, ngakho-ke ama-pulses adluliselwa phakathi kwawo kuzo zombili izinkomba.
Isivinini sendiza sinqunywa ngokusekelwe esikhathini sokushaya kwenhliziyo ngakunye; ithwebula isivinini somoya esinezinhlangothi ezintathu, isiqondiso kanye ne-engeli ngokubeka amapheya amathathu ezinzwa kuma-ax amathathu ahlukene.
I-Centre for Atmospheric Sciences inama-sonic anemometers ayishumi nesithupha, eyodwa yawo ekwazi ukusebenza ku-100 Hz, amabili awo akwazi ukusebenza ku-50 Hz, kanti amanye, asebenza kakhulu ku-20 Hz, ayashesha ngokwanele ekusebenzeni okuningi.
Izinsimbi ezimbili zifakelwe ukushisisa iqhwa ukuze zisetshenziswe ezimeni ezineqhwa. Iningi linokufakwa kwe-analog, okukuvumela ukuthi wengeze izinzwa ezengeziwe ezifana nezinga lokushisa, umswakama, ukucindezela kanye namagesi okulandela umkhondo.
Ama-anemometer e-Sonic asetshenziswe kumaphrojekthi afana ne-NABMLEX ukukala isivinini somoya ezindaweni eziphakeme ezihlukene, futhi i-Cityflux ithathe izilinganiso ezihlukene ezingxenyeni ezihlukene zedolobha.
Ithimba lephrojekthi ye-CityFlux, elicwaninga ngokungcoliswa komoya emadolobheni, lathi: “Ingqikithi ye-CityFlux iwukufunda zombili lezi zinkinga ngesikhathi esisodwa ngokukala ukuthi imimoya enamandla isusa ngokushesha kangakanani izinhlayiya kuxhaxha lwemigwaqo yedolobha.
I-Sonic anemometers intuthuko enkulu yakamuva yokulinganisa isivinini somoya, ukuthuthukisa ukunemba kwezibikezelo zesimo sezulu kanye nokuvikeleka ezimeni ezimbi njengemvula enamandla engabangela izinkinga ngamathuluzi endabuko.
Idatha enembe kakhulu yesivinini somoya isisiza siqonde izimo zezulu ezizayo futhi silungiselele impilo yansuku zonke nomsebenzi.
