Mazhinji emapurojekiti akaitwa mukudzidza kweakanyanya meteorological zviitiko, senge superorned, inoitirwa kunatsiridza kufanotaura kwavo. Chiitiko chakafananidzirwa chakasvika kumhepo dzakatsiga dzinosvika makiromita mazana matatu nemazana paawa, kuuraya vanhu 9 uye kukuvadza vangangoita mazana maviri mumakiromita zana emugwagwa.
Iyo purojekiti yakaitwa neboka reLeigh Orf revatsvagiri ku Cooperative Institute for Satellite Zvidzidzo yakanga isina kusiyana, kunyange hazvo kukwana kwekudzidza, uye mukana wepakomputa (anenge makore matanhatu gare gare) vakavatendera kuti vaite izvi simulation.
Hapana musayendisiti akamboona simulation yedutu rakadai. Rubatsiro rweBluewaters supercomputer paUniversity yeI Illinois rave nesimba mukugadzira madutu akaitika muna Chivabvu 24, 2011. Bluewaters yakatora nguva pfupi yapfuura. mazuva matatu ekuverenga simulation pamwe nekukanganisika kwayo kwese. Kuti uwane pfungwa yehuwandu hwayo, komputa iyo yatinogona kuve nayo kumba kana muhofisi, ingadai yakatora makumi emakore.
Iyo supercomputer yakashandisa mamiriro ekunze chaiwo akanyorwa panguva yekuumbwa uye kwakazotevera kukura kwedutu guru. Nokuda kweizvi, vakafunga kudziya kwekolamu yemhepo mukati medutu, kumanikidza kwemhepo, hunyoro, kana kumhanya kwemhepo.
Nzvimbo uye simulation yeiyo Streamwise vorticity iripo mukati medutu
Zvikamu zvakasiyana zvechizvarwa uye shanduko yedutu rinoratidzwa muvhidhiyo. Pakutanga iwe unogona kuona iyo chizvarwa che supercell zvinova zvinoita kuti kuberekwe chamupupuri. Dzakati wandei dzeaya supercell ivo vanogadzira madutu madiki, izvo zvinosanganiswa ichipa kukurumidza kune rakakura eddy izvo zvinopedzisira zvave iyo superorned.
Panguva imwecheteyo mvura inogadzira rukova rwemhepo yakatonhorera inoita kunge inoita senge rudzi rwe siphon, ichikurudzira chinhu chikuru. Iyo SVC (Streamwise vorticity yazvino) Iko kuzivikanwa kwemvura inoyerera hakumbobata chamupupuri, asi zvinoita kunge ndiyo inogadzira simba rayo.
Pfungwa yechirongwa ichi kugadzira kunyatso kuenzanisa uye woiisa pabasa revamwe mameteorologist kuti vakwanise kushanda nayo.
Zvinodiwa zverudzi urwu rwekudzidza:
Zvinozivikanwa nemasayendisiti nezve aya madutu akakomba uye madutu anopfuura neTexas, Florida neCaribbean, pakati pedzimwe nzvimbo nhasi, ndizvo zvinogona kuitika nekuwedzera zvakanyanya frequency uye kusimba.
Zvinoenderana neongororo ichangoburwa neAmerican Journal of Climate Change, inonyatsoongorora zviratidzo zvemuchadenga zvematutu, yekufananidza supertorning, mune yakatsiga mamiriro ekunze, yaizove nenguva ye kudzokerazve kweanenge makore mazana mapfumbamwe.
Asi kana vaongorori vakafunga nezvezvinhu zvakaita sekusagadzikana kwemhepo uye kudziya kwemakungwa (zvese zvine chekuita nekushanduka kwemamiriro ekunze), vanosimbisa kuti dutu rinoitika makore ese 1000, hazvizotora nguva yakareba kudaro kuzvidzokorora.
Hapana muongorori anogona kutaura chokwadi, kusvika nhasi, kuti shanduko yemamiriro ekunze ingakanganisa sei kusimba kwedutu rimwe. Ivo chete vanoziva kuti ivo vanofanirwa tsvaga kuti chii chinogadzira uye chinotsigira aya madutu nekukurumidza.
Zvakawanda uye zvirinani zvemhando yepamusoro yedhata uye ane simba makomputa makuru achabatsira mameteorologists kujekesa mimwe mienzaniso yekufungidzira.
Nenzira iyi ivo vaigona kuratidza munzira yeiyo chamupupuri, kwete chete kuti chamupupuri chiri kusvika, asi icho mutsa, nekudaro kuwedzera nguva yekuzivisa ye ziviso, muchivaita mukuchinjana yakajeka uye nekukurumidza.
Hupenyu hwaizoponeswa uye mazana emhuri aisazotambura kukuvadzwa.
