Abstract

 Long-term high-resolution wave climate hindcast around Japan based on JRA-55 was conducted. The hindcast shows the good agreement with observations. Wave climate around Japan is represented by average of wave spectrum. The variability of monthly wave spectrum was analyzed by principal component (PC) analysis. The winter first PC mode of the Japan sea side, the eastern Japan Pacific side and the eastern Japan Pacific side can be characterized by the magnitude of wave development, the fluctuation of swell propagating from east and the fluctuation of swell propagating from the Aleutian Islands, respectively. In summer, the typhoon-generated swell has significant impacts on wave spectrum climate. Using average of wave spectrum, the corresponding large scale atmospheric condition is easily understood.
