Abstract: [1] A K-nearest-neighbor (KNN)-based nonparametric nonhomogenous hidden Markov model is developed and applied for spatial downscaling of multistation daily rainfall occurrences using four atmospheric circulations variables (mean sea level pressure (MSLP), east-west gradient of MSLP, north-south gradient of geopotential height at 700 hPa, and total precipitable water content) over a network of 30 rain gauge stations near Sydney, Australia. The proposed model generates rainfall occurrence conditional to a conti…
