and Related Activities (1966-1979) by Michio Yanai Department of Atmospheric Sciences, UCLA |
|
| 1966: Japanese GARP Committee (Chair, G. Yamamoto; Secy., Y. Ogura) formed. Tropical Meteorology Subcommittee: Chair, S. Syono (later I. Imai); Secy., M. Yanai. 1967: Attends GARP Study Conference, Stockholm (with G. Yamamoto and Y. Ogura). Group III: J.G. Charney (leader), J. Bjerknes, D. Lilly, D. Lindzen, K. Ooyama, H. Riehl, and M. Yanai discuss dynamical problems in the tropics, convection processes and mesoscale phenomena, and recommendations. 1968: JOC Study Group of Tropical Disturbances (Pisharoty, Fujita, Yanai) meets in Madison, Wisconsin. The group made cloud cencus based on the satellite- photos of tropical clouds. They identifies major features of cloud organization in the tropics, such as the Equatorial Bands (ITCZ), Monsoon Clusters (super cloud clusters over the Indian Ocean), Convex Band (SPCZ), and "Popcorn" cumulonimbi over Brazil. 1969: Japan TROMEX Planning Committee meets at JMA (September). Yanai attends JOC - 3 in Paris as an expert (October). Ad hoc JOC Study Group of Tropical Disturbances (Charney, Fujita, Manabe, Riehl, Suomi, Wallace, Yanai, Zipser) meets in Miami (December) to further discuss scientific issues and field experiments. 1970: The Planning Conference on GARP Tropical Experiment (Brussels) decides the experiment to be conducted in the Atlantic. Japan withdraws from the tropical experiment, and proposes the Air Mass Transformation Experiment (AMTEX) in the East China Sea. Yanai moves to UCLA (September), begins data preparation for the Q1-Q2 diagnosis of cumulus mass flux (November). 1971: Yanai visits ISMG in Geneve (January), attends U.S. GATE Advisory Panel in Boulder (April). He visits ISMG again and prepares "A Review of Recent Studies of Tropical Meteorology Relevant to the Planning of GATE" (September). At the AMS Conference on Hurricanes and Tropical Meteorology in Barbados (December), Arakawa and Yanai present preliminary versions of the Arakawa-Schubert cumulus parameterization, and Q1-Q2 diagnosis of cumulus mass flux. 1972: Dynamics of the Tropical Atmosphere (Colloquium) in Boulder (July). Tsuyoshi Nitta (University of Tokyo) joins the tropical meteorology project at UCLA (September). Yanai submits the Q1-Q2 paper (Yanai, Esbensen, Chu) to JAS (December). 1973: Yanai attends U.S. GATE Advisory Panel in Tallahassee (January), visits ISMG in Bracknell, attends TEB IV as JOC expert (March), U.S. GATE Advisory Panel in Miami (May). JOC Panel on GATE (Suomi, Sawyer, Miyakoda, Yanai) meets in London (July). 1974: U.S. GATE Advisory Panel in Boulder (February), Washington D.C. (March, November). GATE Field Experiments (June - September). JOC Panel on GATE (Reed, Miyakoda, Yanai) meets in Dakar (September). 1976-1977: T. Nitta's second visit to UCLA. 1979: Attends the Seminar on the Impact of GATE on Large-Scale Numerical Modeling of the Atmosphere and Ocean (Woods Hole, Massachusetts in August). |
