Remind according to the expert: Form incident of ell Ni Nuo formally already 2020 (intensity is weak) . Incident of second ell Ni Nuo is here medium, intertropical big compression ring flows to basically be reflected to the sea is answered lukewarmly for mid model the influence feature of ell Ni Nuo, namely unusual ascendant movement basically is in atmosphere Pacific Ocean of Chinese and Western, since spring on the west Pacific Ocean is subtropic high-pressured intensity slants strong, position slants on the west, ministry of Changjiang Delta southwest to Huanaxi precipitation of greater part of ministry, Qinghai-Tibet Platean slants much.
Suffer incident of this ell Ni Nuo to affect, predict Spring 2020, on the west Pacific Ocean is subtropic high-pressured intensity slants strong, precipitation is overall show " north and south is much, among little " the space distributings, waterlogged overweight drought.
