List of Press Release for the FY2001






An Evergreen Forest Largely Evapotranspires in Northern Thailand under Driest Conditions of Late Dry Season
-New Forest Model Simulation Agrees with Observation Results-
Katsunori Tanaka, Researcher, Hydrological Cycle Research Program

Reported on Yomiuri Newspaper (2001.12.28), etc.

After and before the press presentation, I felt that it is important to introduce my research activities to people outside of my field. It was also a very good opportunity for me to reconsider my own research activities, by taking comments and suggestions from other people, and by thinking the different view points from non-scientist. I will be very happy if I could carry out my research activities, which various people (including myself, of course) would think, "yes, it is very interesting."


Experiments Commenced for Predicting Oceanic Variability Near Japan
Toshio Yamagata, Program Director and Yasumasa Miyazawa, Reseracher,Climate Variation Research Program

Reported on Japan Industrial Newspaper (2001.12.21),etc.

This press release means not only to show the finished results but also to continuously give the results by predicting the ocean variation and verifying it. For that reason, in addition to the researchers, we have to rely on various people including public relation personnel, and engineers at the data bank. We should like to enlighten our research results by facilitating the close co-operation of these joint activities.


Discovery of an "Atmospheric Bridge" Extending from the North Pacific to the North Atlantic
-Seesaw between the Aleutian and Icelandic Lows-
Hisashi Nakamura, Group Leader, and Meiji Honda, Researcher, Climate Variation Research Program

Reported on Japan Economic Newspaper (2001.12.5),etc.

We had to make a strong effort to make the dynamical mechanism, North Pacific's circulation variation will effect further to the North Atlantic by this "Atmospheric Bridge", understandable.

Yet we assume that may people got interested in this fact that this "Atmospheric Bridge" is the phenomenon which will have effect on whether in wide areas. We are now studying the predictability of the weather in the end of winter in Europe and Far East by the atmospheric movement over the North Pacific of the severe winter season.

In addition, by analyzing the long term data, we have started to understand that there are periods where the sea sow realationship will be stonge or weakened.



Indian Ocean Dipole Phenomenon's Impact on Correlation between Indian Monsoon and El Nino/Southern Oscillation
Toshio Yamagata, Program Director, Ashok Karumur, Researcher, and Guan Zhaoyong, Climate Variation Research Program

Reported on Daily Industrial Newspaper (2001.12.3),etc.

Using the observational data and the FrAM1.0 AGCM, we found that (i) the Indian Ocean Dipole (IOD) had a significant impact on the Indian summer monsoon rainfall (ISMR) in the last two decades of the 20th century.

(ii) The anomolous subsidence (upward motion) over the anomolously cold (warm) eastern pole of the IOD during a positive (negative)IOD event causes intensified cross-equatorial flow, resulting in anomolous convergence (divergence) over the Bay of Bengal and the monsoon trough region over India and hence surplus (deficit) summer monsoon rainfall.

(iii) The IOD's influence on the ISMR is opposite to that of the ENSO.

Last two decades of 20th century have witnessed frequent and intense IOD events. These IOD events, because of their opposing impact to that of the ENSO on ISMR, have resulted in the apparent weakening of the recently observed ENSO-ISMR relationship.

These results show that the IOD has influence across the equator,and may be very important for the prediction of the ISMR. Motivated by these results, we are doing extensive AGCM studies to comapre and contrast the influence of the IOD on the Asian climate.



Intercontinental Transport of Ozone Pollution Air Pollutant Emissions in East Asia Accelerate Global Warming
Hajime Akimoto, Program Director, and James Oliver Wild, Researcher, Atmospheric Composition Research Program

Reported on Yomiuri Newspaper (2001.11.9),etc.

I'm glad to be working in an area of science that is of general public interest and that is sufficiently policy-relevant that the media pick up on it. Clearly this type of interest is immensely encouraging for our research, and should serve to both educate the public in our discipline and to help support our scientific field in general. It's very nice to be able contribute something to the progress of Frontier. (Oliver Wild)


Wake of Hawaii discovered to Extend Several Thousand Kilometer
Masami Nonaka, Researcher and Shang-Ping Xie, Researcher, International Pacific Research Center

Reported on Tokyo Newspaper (2001.6.5),etc.

Our paper reports on the discovery of a new phenomenon in which journalists present at the press conference were very interested. But they also showed a strong interest in its applications in particular those that affect our everyday life. I was struck by the application-oriented perspectives of journalists, which led me to think harder than ever about how to link our research to our daily life. Maybe inspired by this experience, we are currently embarking on a project that studies air-sea interaction in the Kuroshio-Extension east of Japan, a key region to the North Pacific climate variability.


Effective Control of Global Warming by Simultaneous Reduction of NOx and CO Emissions
Hajime Akimoto, Program Director and James Oliver Wild, Researcher, Atmospheric Composition Research Program

Reported on Sankei Newspaper (2001.5.3),etc.

The NOx-Global Warming research is temporally suspended, as further research in the area requires a more detailed calculation of radiative forcing, and I don't currently have access to a good radiative code.

However, the Intercontinental Transport research is continuing, with more specific focus on the import and export of oxidants and their precursors over the East Asian region. This work has been given added relevance by the recent international TRACE-P measurement campaign over the western Pacific last spring, for which we are contributing detailed modelling studies.(Oliver Wild)
