Uqikelelo oluchanekileyo lokuna kweemvula ezinesisombululo esiphezulu se-spatiotemporal lubalulekile kusetyenziso lwemibhobho yamanzi yasezidolophini, kwaye ukuba luhlengahlengiswe kuqwalaselo lwasemhlabeni, idatha yerada yemozulu inokuba nokwenzeka kwezi zicelo.
Ubuninzi beegeyiji zemvula zemozulu ukuze kuhlengahlengiswe, nangona kunjalo, zihlala zimbalwa kwaye azisasazwanga ngendlela efanayo emajukujukwini. Izixhobo zoluvo zokuna kwemvula ezinethuba zibonelela ngoxinaniso olwandisiweyo lokuqwalaselwa komhlaba kodwa rhoqo ngokuncipha okanye ukuchaneka okungaziwayo kwisikhululo ngasinye. Eli phepha libonisa ukudityaniswa kwedatha evela kwi-radar yemozulu, izikhululo zemozulu zobuqu, kunye nekhonkco lorhwebo lwe-microwave kwimveliso yemvula edibeneyo. Ukudibanisa uqikelelo lwemvula olungenelelayo luboniswa ukuphucula ukuchaneka koqwalaselo lwemvula enethuba ngenkqubo yolawulo lomgangatho. Kolu phononongo, sibonisa ukuba ukuchaneka koqikelelo lwemvula kuphuculwe kakhulu ngokudibanisa idatha yemvula enethuba kunye nedatha yerada yemozulu xa kuthelekiswa nokuchaneka kwemveliso nganye yemvula ngaphandle kokudibanisa. Amaxabiso eNash-Sutcliffe efficient (NSE) ukuya kuthi ga kwi-0.88 afunyenwe kwimveliso yemvula edityanisiweyo yemihla ngemihla, ngelixa ixabiso le-NSE lemveliso yemvula nganye lisukela ku- -7.44 ukuya ku-0.65, kwaye utyekelo olufanayo luyajongwa kwi-root mean squared error (RMSE) ixabiso. Ukudityaniswa kwerada yemozulu kunye neenkcukacha zokuna kwemvula, indlela entsha, okt, "uhlengahlengiso oluphakathi komyinge ophakathi" luyanikezelwa. Ukusebenzisa le ndlela, imveliso yemvula ephezulu ifumaneka ngokuzimeleyo kwimilinganiselo yemvula eqhelekileyo, apho kule sifundo isetyenziselwa ukuqinisekiswa okuzimeleyo. Ukongeza, kuboniswa ukuba uqikelelo lwemvula oluchanekileyo lunokufunyanwa ngokudibanisa imihla ngemihla, kugxininisa ukubaluleka kokudibanisa kwi-nowcasting kunye nezicelo ezikufutshane zexesha langempela.
