摘要:
In June 1986 the Jet Propulsion Laboratory (JPL, in Pasadena, Calif.) organized and carried out a series of long‐baseline geodetic measurements using Global Positioning System (GPS) satellites to measure plate motion between the North American and Caribbean plates. The GPS technique uses radio signals from a group of navigation satellites placed in orbit by the U.S. Department of Defense. The system is currently capable of measuring baselines of a few hundred kilometers' length within an accuracy of a few centimeters, and further improvements are expecte

摘要:
A reorganization of the Office of Space Science and Applications was announced at National Aeronautics and Space Administration (NASA) Headquarters in Washington, D.C., on September 8, 1987. An important result of this reorganization for members of the AGU Solar‐Planetary Relationships (SPR) Section is the formation of a new Space Physics Division (Code ES), which includes the Space Plasma Physics Branch of the Earth Science and Applications Division, the Solar Physics Branch of the Astrophysics Division, and particle astrophysics/cosmic ray studies formerly overseen by the Astrophysics Division. The new division is divided into four science branches, including Cosmic and Heliospheric Physics, Solar Physics, Magnetospheric Physics, and Ionospheric Physics. The proposed division structure is given in the box. Current division personnel have been assigned responsibilities as presented in the box, but it is expected that the “activity” positions within the division will be filled through open competition within the next 2 years. Division goals, areas of research, and specific branch responsibilities are as fo

摘要:
TheGlossary of Meteorology(American Meteorological Society, Boston, Mass., 1959) defines dynamic meteorology as “the study of atmospheric motions as solutions of the fundamental equations of hydrodynamics or other system of equations appropriate to special conditions.” This definition fits Panchev's book quite well, although the author prefers to call its subject “fluid dynamics of the atmosphere.” The emphasis in this volume, however, is on the formal treatment of equations rather than on the physical explanation of atmospheric motions. The book has been written on the basis of classes on dynamic meteorology taught at the University of Sofia, Bulgaria. In this respect, the book also gives readers outside of this scientific community some insight into Eastern European education on dynamic mete

摘要:
The reported doubling of atmospheric methane over the past century and its impact on global climate change prompted this symposium, which was hosted by the Division of Geochemistry of the American Chemical Society during its meeting in Denver, Colo. (April 5–10, 1987). The goal was to establish an interdisciplinary forum for current research related to aspects ofthe chemistry of methane in Earth's atmosphere;the identification of its sources;its microbiological mechanisms of formation and oxidation; andmeasurements of its outward flux from various source

摘要:
A small group of scientists gathered together in Tallahassee, Fla., February 10–12, 1987, for the Second Annual Workshop on Dusty Plasma Physics. Inspired by the success of the first workshop, held in San Diego, Calif., January 1986, coconvenors Mihaly Horanyi (Florida State University, Tallahassee) and Harry Houpis (University of Michigan, Ann Arbor) decided to keep the small, informal format of 1‐2 hour talks with open discussion through

摘要:
The AGU Tectonophysics Section selected Gary Acton to receive their Best Student Paper Award for the 1987 Spring Meeting. His award‐winning paper was entitled “Generalized Rift Propagation and Microplate Kinematics.”Acton, who is currently working on his Ph.D. in geophysics at Northwestern University (Evanston, Ill.), received his B.S. in geology in 1984 from Indiana University, Bloomington, and his M.S. in geophysics in 1986 from the University of Arizona, Tucson. At Northwestern, he is currently studying the kinematics of propagation rift systems with Seth Stein and Joseph Engeln, the coauthors of the award‐winning paper. He is also investigating Cretaceous paleomagnetisin of the Pacific and North American plates with Richard Gordon and Katerina Pet
