New TopicProgram Activity

Starting from this edition, we would like to introduce, resent research, participating conferences, and other activities going on in six programs in Institute for Global Change Research, and two research centers in Hawaii and Alaska.

Climate Variations Research Program
Since August, three researchers, including two overseas guest researchers have joined the program. One of the guest researchers is Dr. Bhaskar Rao, a professor from Andhra University in India. As a foremost researcher in areas such as cumulus parameterization and radiation schemes, he has built a numerical model for clarifying climate variation. In our program, Dr. Rao will be involved in a project to improve the modular atmospheric general circulation model (FrAM).

Our new young genius member, Dr. Sebastien Masson, just graduated from University of Paris is a coupled atmosphere-ocean modeler with a bright future in international sphere. He has clarified the role of fresh water flux in the large-scale atmosphere-ocean interaction of the Tropical Indian Ocean. He chose our research pro-gram for his post-doctorate because of the world leading research on the dipole mode event (DME). He is eager to pro-mote joint research between the FRSGC and the European Union, using the EU's coupled atmosphere-ocean general circulation model.

Dr. Guan Zhaoyong, previously achieved great results at this research program as an STA fellow, before advancing to the position of full-time professor at Nanjing Institute of Meteorology, has finally returned as a full-time researcher. He intends to elucidate teleconnections and other phenomena with the atmosphere-ocean general circulation model, utilizing the previous data analysis studies of the Arctic Oscillation and Antarctic Oscillation.

Hydrological Cycle Research Program
Program Director Dr.Yasunari, and five of our researchers,Drs. Masuda, Tomita, Yamazaki, Kuba, and Maruyama participated in the 8th Scientific Assembly of International Association of Meteorology and Atmospheric Sciences (IAMAS).

The presentations included discussions on the results of initial analyses from an international comparison of snow cover models, an introduction to newly developed microphysical models for cloud simulation, an introduction to results from models that simulate the aggregation process in snowflake growth, and the results of data analysis concerning the Asian Monsoon circulation. The group was able to gain valuable insights from the conference for future research.

In early September, the 4th International Scientific Conference on the Global Energy and Water Cycle (GEWEX) was held in Paris. Dr. Yasunari, Vice-Chair of the GEWEX Scientific Steering Group (SSG), together with Drs. Masuda, Suzuki, and Fukutomi participated in the conference. The conference is expected to stimulate research on predicting hydrological cycles concerning seasonal change and interannual variability in the atmosphere-land water budget, along with the role of vegetation.

Dr.Kishtawal has been using data from Tropical Rainfall Measuring Mission (TRMM) thereby advancing analysis of the distribution of the height of rain tops over the sea, with respect to sea surface temperature and monsoon circulation. Dr.Sung-Dae Kang from the Meteorological Research Institute of Korea Meteorological Administration joined us from July.

Global Warming Research Program
Following is the report by Mr. Yoshiharu Iwasa after participating in an overseas conference.

I attended the 8th Scientific Assembly of InternationalAssociation of Meteorology and Atmospheric Sciences(IAMAS), in Innsbruck, Austria from July 10 to 18. The conference began with lectures from invited speakers, who spoke about the latest issues from the IPCC Report, followed by presentations spanning a wide range of research fields within atmospheric science.

During the session on climate models, I delivered an oral presentation on circulation mechanisms determining water vapor distribution in the radiative-convective equilibrium of the Earth's atmosphere. Although many presentations of research results using large-scale GCMs, while I presented results of research using a simple model, I was pleased with the number of people who gathered to hear my talk. I received questions and comments from several people in the audience, but only afterwards was I to discover that they were well-known and eminent experts. Istill feel a mixture of excitement and shivers thinking about it.

On Sunday, I visited Stubaital, and from the STB(train) window on the return journey, I was able to see a beautiful rainbow over a church in an Alpine village.

Atmospheric Composition Research Program
In June, the Workshop on Emissions of Chemical Species and Aerosols was held in Paris. Program Director Dr. Akimoto, Sub-leader Dr. Ohara, researcher Dr. Yan, and research staff Ms. Yamaji attended the workshop and the emission inventory subgroup gave its first presentation.

Dr. David Streets was invited from Argonne National Laboratory in the U.S. for a seminar at our institute on September 3. In collaboration with Dr. Streets, the Atmospheric Composition Research Program aims to develop a high-resolution emission inventory for the Asian region.

In July, seven members of the research program participated in the 8th Scientific Assembly of InternationalAssociation of Meteorology and Atmospheric Sciences (IAMAS) in Innsbruck. The seven participants included Program Director Dr. Akimoto and researchers Drs. Wild, Takigawa, Zhang, Pochanart, Kanaya, and Naja.

Preparations in the research program are also under way for the Symposium on Atmospheric Composition Change: Toward the Integration of Observation and Modeling, which will be held on November 19 and 20 at the Yokohama Institute for Earth Sciences.
