Ko sonic anemometers inogona kuvandudza mamiriro ekunze?

Isu tanga tichiyera kumhanya kwemhepo tichishandisa anemometer kwemazana emakore, asi kufambira mberi kwazvino kwakaita kuti zvikwanise kupa fungidziro yemamiriro ekunze yakavimbika uye yechokwadi. Sonic anemometers inoyera kumhanya kwemhepo nekukurumidza uye nemazvo zvichienzaniswa neshanduro dzechinyakare.
Nzvimbo dzeSainzi yeAtmospheric dzinowanzoshandisa midziyo iyi pakuita zviyero zvenguva dzose kana ongororo dzakadzama kubatsira kuita fungidziro yemamiriro ekunze enzvimbo dzakasiyana siyana. Mamwe mamiriro ezvakatipoteredza anogona kuderedza kuyerwa, asi kumwe kugadzirisa kunogona kuitwa kukunda matambudziko aya.
Anemometers yakaonekwa muzana remakore rechi15 uye yakaramba ichivandudzwa uye yakagadziridzwa mumakore achangopfuura. Anemometers echinyakare, akatanga kugadzirwa pakati pezana ramakore rechi 19, anoshandisa kurongeka kwedenderedzwa kwemakapu emhepo akabatanidzwa kune data logger. Mumakore ekuma1920, vakava vatatu, vachipa mhinduro inokurumidza, inowirirana inobatsira kuyera kuvhuvhuta kwemhepo. Sonic anemometers ikozvino inhanho inotevera mukufanotaura kwemamiriro ekunze, ichipa kunyatsojeka uye kugadzirisa.
Sonic anemometers, yakagadzirwa muma1970s, inoshandisa masaisai eultrasonic kuyera nekukasira kumhanya kwemhepo uye kuona kana masaisai eruzha anofamba pakati pemasensa maviri ari kukwidziridzwa kana kudzikiswa nemhepo.
Iye zvino vari kushambadzirwa zvakanyanya uye vanoshandiswa mune dzakasiyana siyana dzezvinangwa nenzvimbo. Maviri-dimensional (kumhanya kwemhepo uye kutungamira) sonic anemometers anoshandiswa zvakanyanya munzvimbo dzemamiriro ekunze, kutakura, mhepo turbines, ndege, uye kunyange pakati pegungwa, inoyangarara pamusoro pemamiriro ekunze.
Sonic anemometers inogona kuita zviyero zvine nguva yakakwira resolution, kazhinji kubva pa20 Hz kusvika 100 Hz, zvichiita kuti dzinyatsokodzera zviyero zvemhirizhonga. Mamhanyiro uye zvigadziriso muzvikamu izvi zvinobvumira kuyerwa kwakaringana. Iyo sonic anemometer ndeimwe yezviridzwa zvitsva zvemamiriro ekunze mune zviteshi zvemamiriro ekunze nhasi, uye yakatonyanya kukosha kupfuura vane mhepo, iyo inoyera mafambiro emhepo.
Kusiyana neshanduro dzechinyakare, sonic anemometer inoda hapana zvikamu zvinofamba kuti zvishande. Vanoyera nguva inotora kuti ruzha rwufambe pakati pemasensa maviri. Nguva inotarwa nechinhambwe chiri pakati pemasensa aya, uko kumhanya kweruzha kunoenderana nekupisa, kudzvanywa uye zvinosvibisa mweya zvakaita sekusvibiswa, munyu, huruva kana mhute mumhepo.
Kuti uwane ruzivo rwekumhanya kwemhepo pakati pema sensors, sensor yega yega inoita senge inotumira uye inogamuchira, saka mapurusi anofambiswa pakati pavo munzira mbiri.
Kumhanya kwendege kunotemerwa zvichienderana nenguva yekupuruzira munzira imwe neimwe; inobata matatu-dimensional mhepo yekumhanya, kutungamira uye kona nekuisa matatu mapeya emasensor pamatemo matatu akasiyana.
The Center for Atmospheric Sciences ine gumi nenhanhatu sonic anemometers, imwe yacho inokwanisa kushanda pa100 Hz, maviri ayo anokwanisa kushanda pa50 Hz, uye mamwe, ayo anonyanya kukwanisa kushanda pa20 Hz, anomhanya zvakakwana kune akawanda maoparesheni.
Zviridzwa zviviri zvine anti-ice kudziyisa kuti zvishandiswe mumamiriro echando. Mazhinji ane analog yekupinda, achikubvumidza iwe kuwedzera mamwe ma sensors senge tembiricha, humidity, kudzvanywa uye kutsvaga magasi.
Sonic anemometers yakashandiswa mumapurojekiti akadai seNABMLEX kuyera kumhanya kwemhepo munzvimbo dzakasiyana, uye Cityflux yakatora zviyero zvakasiyana munzvimbo dzakasiyana dzeguta.
Chikwata cheCityFlux chirongwa, chinoongorora kusvibiswa kwemhepo yemumaguta, chakati: "Chakakosha cheCityFlux kudzidza matambudziko ese ari maviri panguva imwe chete nekuyera kuti mhepo ine simba inokurumidza kubvisa sei zvinhu kubva kune network yemigwagwa yemuguta 'makoronga'. Mhepo iri pamusoro pawo ndipo patinogara nekufema. Nzvimbo inogona kupeperetswa nemhepo."

Sonic anemometers ndiyo yazvino budiriro yakakura mukuyerwa kwekumhanya kwemhepo, kuvandudza iko kurongeka kwemamiriro ekunze uye kusadzivirirwa kumamiriro ezvinhu akashata akadai semvura zhinji inogona kukonzera matambudziko nezviridzwa zvechinyakare.

Yakanyatsorongeka data yekumhanya kwemhepo inotibatsira kunzwisisa mamiriro ekunze ari kuuya uye kugadzirira hupenyu hwezuva nezuva nebasa.
