Ambiri olosera zamphongo sanaphonye chizindikiro, mwina pang'ono kapena mopepuka kuwerengera nambala ndi ukali wa mkuntho. Kumayambiriro kwa chaka, olosera ankaganiza kuti El Niño idzayamba, kuchepetsa ntchito yamkuntho.

Chaka cha 2017 chinali ndi nyengo yoposa yachiwiri yomwe inachititsa kuti mvula yamkuntho ikhale 17, mafunde amphamvu 10, ndi mphepo zamkuntho zisanu ndi zikuluzikulu. Pano pali momwe otsogolera akuyendera ndi maulosi awo mu nyengo ya 2017.
- NOAA (National Oceanic and Atmospheric Administration) idakayikira nyengoyi, yatsimikizira nyengo ya "yapamwamba" yomwe ili ndi 11 mpaka 17 yotchedwa mphepo yamkuntho, mphepo zamkuntho zisanu ndi zisanu ndi zinayi, kuphatikizapo mphepo zamkuntho zazikulu ziwiri kapena zinayi.
- Zolinga zamtundu wa Global Weather Oscillations Inc. (GWO) zinaneneratu zapamwamba-zochitika zomwe zimakhalapo ndi mphepo zamkuntho zina 16, mafunde asanu ndi atatu, ndi mphepo zamkuntho zinayi.
