The contents of this volume are based largely on a symposium on cloud
dynamics held in Hamburg, Germany, as a part of the Third General
Assembly of the International Association of Mete- orology and
Atmospheric Physics (IAMAP), 17-28 August-1981. Plans for this symposium
were initiated by the Cloud Dynamics Group, appointed through the
International Commission for Dynam- ic Meteorology (ICDM), IAMAP.
Members of this group are Bruce Morton - Chairman, Australia; Tomio
Asai - Secretary, Japan; E. M. Agee, USA; V. Andreyev, Bulgaria; K.
Fradrich, FRG; M. W. Moncrieff, UK; R. S. Pastushkov, USSR; J. P. Chao,
PR China; Bh. V. Ramanamurti, India; W. Roach, UK; J. Simpson, USA; J.
T. Steiner, New Zealand; M. Yanai, USA. E. M. Agee served as con- vener
of the symposium in Hamburg. Dynamic meteorology has grown rapidly and
covered a great variety of fields since the foundation of ICDM, making
it increas- ingly difficult for the Commission to manage all activities.
In order to improve this situation, some ad-hoc Working Groups within
ICDM were organized at the 1977 IAMAP meeting in Seattle. Each of these
working groups, such as the one in Cloud Dynamics, deals with a
particular sub-field of dynamic meteorology.
