- Research Activities
[Atmospheric and Oceanic Disaster]
We promote the following researches to clarify phenomena in atmosphere-ocean-land system and evaluate hazards.
1.Advanced utilization of numerical weather forecast model
- Mechanism and forecast of tropical cyclones, heavy rainfall, and freezing rain
- Regional atmospheric reanalysis over Japan
- Future projection of regional climate for climate change adaptation
2.Application of land-surface model to disaster science
- Plant blight and frost damage
3.Impact of ocean changes on meteorological and marine disasters
- Understanding marine heatwaves that cause meteorological and oceanographic disasters and elucidating their mechanisms
[Outer Space Disaster]
In order to make a bridge between research and operation,
we promote scientific and engineering studies
to reduce space environment risks on the activities in outer space.
Main research items are following.
1.Studies on measures to ensure the safe and sustainable use of outer space
2.Space hazard prediction with assessment of forecast tools
3.Solar radio wave monitoring for the operation of space weather forecast

Density stratification tends to be strengthened in more than 80% of the entire ocean, and on average, it corresponds to a maximum of 6.1% strengthening from the 1960s to the present. It can cause abnormally high sea surface temperature.
