摘要：Duration of calm wave state or harsh wave state is an important factor for planning and designing offshore operation. The statistical characteristics of wave state duration, such as three days calmness ratio, is studied using long term reanalysis data. The spatial distribution of duration statistics for sea around Japan is illustrated through data analysis. We also attempt to reproduce the duration statistics by assuming a Markov process. Our assumption is verified by Markov Chain simulation. After considering multistage and high order Markov processes, a simple first order 2-state Markov process, provided the transition matrix is defined monthly, is found to be efficient to describe the desired duration statistics. The simplified stochastic process allows us to generate synthetic data of various lengths for further consideration.
