Abstract
In this study we adopted the Nonhomogeneous Hidden Markov Model NHMM approach proposed by Hughes and Guttorp 1994 to stochastically link the Sea Surface Temperature SST anomaly field in Pacific Ocean to local high precipitation anomaly event. The NHMM approach postulated the existence of unobserved weather states which serves as a link between the large scale SST anomaly and the extreme precipitation event at four local rain gauge stations. A 45-year sequence of monthly data was used for modelling. It is noticed that the low SST anomaly in the middle of Pacific Ocean and relatively high SST anomaly to the North tends to increase the occurrence probability of extreme precipitation in local stations.
