A special, full-day session on “Investigation of Mesoscale Precipitation Fields” is being organized by the precipitation committee of AGU's Hydrology Section for the 1984 AGU Spring Meeting under the joint sponsorship of the Hydrology and Atmospheric Sciences sections. This session will contain about 10 invited talks by hydrologists, atmospheric scientists, statisticians, and mathematicians, with a new focus on interdisciplinary research in modeling precipitation fields. In the evening, a 2-hour panel discussion will be held to explore in depth the scope of interdisciplinary research and climatic variability. For additional details contact: Vijay K.
