I-Lagrange Drifting Buoy eLahlwayo (Uhlobo lwe-SVP) – Ukujonga Ubushushu kunye neSalinity yoLwandle,
i-buoy elahlwayo yeLagrange yokukhukuliseka ukuze ijonge umsinga wolwandle, isixhobo sokuntywila esilahlwayo sophando lwaselwandle, i-buoy eshukumayo yokuthintela ubushushu bomphezulu wolwandle kunye netyuwa, I-GPS yokuqhuba ulwandle, I-Lagrangian drifter yokujonga umphezulu wamanzi, I-SVP drifter yokujonga iilwandlekazi, I-SVP drifting buoy eneGPS,

Iiparameters zobugcisa

Imisinga yolwandle iqhubeka nokuthutha ubushushu, ityuwa, izondlo, ukungcola, kunye nezinto ezidadayo kuyo yonke indawo yolwandle. Ukuqonda indlela le misinga ehamba ngayo kubalulekile kuphando lwe-oceanography, ukujonga imeko-bume yolwandle, izifundo zemozulu kunye nemozulu, kunye nomzekelo wokujikeleza kolwandle.

Ngokungafaniyo nesikhululo sokujonga ulwandle esizinzileyo, i-Lagrangian drifting buoy ihamba namanzi ajikelezileyo. Ngokulandela indawo ye-buoy ngokuhamba kwexesha, abaphandi banokuqikelela intshukumo yobunzima bamanzi apho i-buoy ishukuma khona.

I-FrankStar Disposable Lagrange Drifting Buoy (SVP Type) yenzelwe ukujonga umsinga wolwandle nolwandle, ubushushu, kunye netyuwa, ngelixa irekhoda indawo ye-GPS ye-buoy.

Uyilo lwayo olulahlwayo lwenza ukuba ifaneleke kwimisebenzi yokujonga apho i-buoy isetyenziswa ixesha elithile kwaye akufuneki ifunyanwe emva kokugqiba umsebenzi wayo wokulinganisa.

Yintoni iLagrangian Drifting Buoy?

I-Lagrangian drifting buoy, okanye i-sea drifter, liqonga lokujonga elihamba ngokukhululekileyo elilandela intshukumo yolwandle olujikelezileyo.

Kukho iindlela ezimbini eziqhelekileyo zokufunda ngentshukumo yolwandle:

Ukuqwalasela kuka-Eulerian

Imizekelo ibandakanya:

Iinqanawa ezirhubuluzayo elwandle

Ii-SVP drifters

Ii-buoys zedatha ezijikelezayo

Umahluko ophambili ngulo:

Eulerian = Jonga utshintsho kwindawo emiselweyo

ILagrangian = Jonga utshintsho xa uhamba namanzi

Ngoko ke, i-Lagrangian drifter inika ulwazi oluxabisekileyo malunga nokuhamba kunye neempawu zamanzi ngokwawo.

Yintoni i-SVP Drifter?

I-SVP idla ngokubhekisa kuyilo lwe-Surface Velocity Program drifter olusetyenziselwa ukujonga ukujikeleza kolwandle kufutshane nomphezulu.

I-drifter yohlobo lwe-SVP idla ngokuba ne-surface float kunye ne-subsurface drogue okanye i-drag element efanayo eyenzelwe ukudibanisa intshukumo ye-drifter ngokusondeleyo nomsinga wolwandle ojikelezileyo kubunzulu bokujonga ekujoliswe kuko.

Oku kunceda ukunciphisa impembelelo yentshukumo eqhutywa ngumoya ngqo kumphezulu we-float kwaye kuvumela indlela yokujika imele ngcono intshukumo yomaleko wamanzi ekujoliswe kuwo.

Uyilo oluthile kunye nobunzulu bokusetyenziswa buxhomekeke kulungiselelo lwemveliso kunye neemfuno zeprojekthi.

Isebenza Njani I-Lagrangian Drifting Buoy?

Inkqubo esisiseko yokujonga ingashwankathelwa ngolu hlobo:

Ukusasazwa → Ukushukuma Ngomsinga Wolwandle → Ukulinganiswa Kwenzwa → Indawo Yokubeka I-GPS → Ukuhanjiswa/Ukugcinwa Kwedatha → Uhlalutyo Lweendlela

Emva kokuthunyelwa, i-buoy ihamba elwandle.

Ngamaxesha amiselweyo okuthatha iisampulu, izinzwa ezikwinqwelo ziqokelela imilinganiselo yokusingqongileyo efana nale:
