4. Two members of TWAS: Prof. Q.C.Zeng and Prof. M. Mu One young affiliate of TWAS: Prof. X.D. Zeng One Center of Excellence: More than 10 PhD students from the developing world

5. CAS-TWAS-WMO Forum Background Established in 2000 by three presidents of the three organizations Lu Yongxiang （ Former President of CAS ） Mohamed H. A. Hassan （ Former Executive Director of TWAS ） G.O.P.Obasi (Former Secretary-General of WMO) In order to facilitate the study and solution of important scientific problems related to climate problems such as global warming short-term climate anomalies the disastrous weather events adaptations

6.  Bring together high level experienced mathematicians, physicists, and scientists in related fields and to exchange ideas, discuss scientific problems in depth and develop suitable solving methods by joint efforts;  Utilizing the united platform of CAS, TWAS, and WMO, further promoting global academic exchange and cooperation in climate field among developing countries.  Make valuable contributions to the cultivation and training of young research talents in developing countries. A symposium/workshop/training courses for different topics will be held each year.

7. CAS-TWAS-WMO Forum Organizations The Organization of CTWF consists of chairmen and executive directors from CAS, TWAS and WMO respectively.  Co-Chairs for the Forum ： Lu Yongxiang （ Academician, President, CAS ） Mohamed HA Hassan （ Prof., Executive President, TWAS ） Michel Jarraud (Prof., Secretary-General, WMO)  Executive Chairmen ： Qingcun Zeng (Academician, CAS and member of TWAS ） Filippo Giorgi (Dr., ICTP) David Carson (Executive Director of WCRP) Huijun Wang (Prof., Director of IAP/CAS)

8. Forum Support from CAS Funding Support Since the inception of the CTWF, CAS provides a 300, 000CNY/year fund for the annual organization of CTWF. TWAS office in CAS TWAS office in CAS spares no efforts to the propaganda of the CTWF through the platform of TWAS. Besides, the office maintain sound communication with TWAS headquarter, further obtained CTWF more support from TWAS. Great attention and support from the presidents of CAS Present of CAS, Prof. Chunli Bai attended the 2010 CTWF in Beijing.

14.  With the continuous supports from the Chinese Academy of Sciences, the CAS- TWAS-WMO Forum has significantly strengthened the relationship between CAS, TWAS, and WMO.  The Forum activities have been one of the China’s important contributions to the TWAS.  The Forum international symposiums/workshops has also provided an excellent opportunity to bring together international renowned research scientists from several different fields: mathematics, physics and climate research, etc. This is the unique feature of the symposium, and has significantly contributed to climate science development. Until now, more than 120 young research scientists have been supported by CTWF. In the 2003 international training workshop, 28 oversea participants from developing countries received financial support from CTWF; In the CTWF 2010 international workshop, over 35 young research scientists from developing countries were granted by CTWF.
