1. Long-term wave hindcasts

We conducted long-term wave hindcasts nesting from global (resolution 60km) to Japan (7km) from 1979-2012. The used spectrum wave model is WAVEWATCH III (version 4.16) and the atmospheric forcing to wave model is JRA-55.

Data description

Output variables

  • Annual mean
    • significant wave height, mean wave periods, mean wave direction
  • Annual maximum
    • significant wave height

There are two differrent definitiono of significant wave height. Please read Shimura and Mori (2019) in detail.

2. Climate projection data: d4PDF tropical cyclone track

We provide tropical cyclone track data of database for Policy Decision making for Future climate change (d4PDF). The data contains locations, intensities and radii of TC. It may useful to extract extreme events of d4PDF.

Data description

Methodology

The extraction of TC tracks of d4PDF is based on Shimura et al. (2016). Please check reference.
