Amahirwe yimvura yerekana amakuru kugirango yongere igereranyo cyimvura

Ikigereranyo cyimvura nukuri hamwe nigisubizo cyinshi cya spatiotemporal ningirakamaro mubikorwa byo gutemba byo mumijyi, kandi iyo bihinduwe nubushakashatsi bwubutaka, amakuru yimiterere yikirere afite ubushobozi bwibi bikorwa.

Ubucucike bw'imvura y'iteganyagihe kugira ngo ihindurwe, nyamara, ni gake kandi idakwirakwizwa mu kirere. Amahirwe yimvura itanga amahirwe yo kwiyongera kubutaka ariko akenshi bigabanutse cyangwa bitazwi neza kuri buri sitasiyo. Uru rupapuro rwerekana guhuza amakuru kuva radar yikirere, ikirere cyihariye, hamwe na microwave yubucuruzi mubicuruzwa byimvura ihuriweho. Guhuza ibigereranyo by'imvura igereranijwe byerekanwe kunoza ukuri kw'imvura ihindagurika binyuze muri algorithm yo kugenzura ubuziranenge. Muri ubu bushakashatsi, twerekana ko igereranyo cy’imvura cyongerewe cyane muguhuza amakuru yimvura itunguranye hamwe namakuru ya radar yikirere ugereranije nukuri kuri buri gicuruzwa cyimvura kitavanze. Nash-Sutcliffe ikora neza (NSE) igera kuri 0.88 iboneka kubicuruzwa byegeranijwe byahujwe buri munsi, mugihe NSE-indangagaciro yibicuruzwa byimvura kugiti cyavuye kuri .4 7.44 kugeza 0.65, kandi imyumvire isa nayo igaragara kumuzi bivuze ikosa (RMSE). Kugirango uhuze ikirere cya radar hamwe namakuru yimvura yamahirwe, uburyo bushya, ni ukuvuga, "kwimuka hagati ya bias kubogama". Gushyira mu bikorwa ubu buryo, umusaruro wimvura ukora cyane ukomoka kubwigenge busanzwe bwimiterere yimvura yo murwego rwohejuru, murubu bushakashatsi bukoreshwa gusa mukwemeza kwigenga. Mubyongeyeho, herekanwa ko igereranya ryimvura rishobora kuboneka mugihe cyo munsi ya buri munsi, bishimangira akamaro ko guhuriza hamwe no gutangaza amakuru hafi yigihe gikwiye.
