"Detection of the weather change in the ocean over 10-50 year's scale"
Toshio Suga (Physical Oceanography Laboratory, Tohoku University)
Earth's atmosphere and ocean climmate shows variation in 10 to a few
scores of years time scale. There is a transition in mid-70s in this system,
and it is addressed as "Regime Shift". The correlation between this and
the global climate change is now one of the hottest topic in the
meteorology.
The central area of the northern Pacific Ocean creates "Central Mode
Water" that might contribute to the large scale weather change. The
most recent Regime Shift occurred around 1998-99 and the expedition
this time between Hilo and Honolulu is to study the Central Mode Water
and any characteristics change in this area.
