摘要:
The auroral zone provides a natural laboratory for studies of plasma phenomena. In this laboratory, waves and nonlinear electrostatic and electromagnetic structures are produced and ions and electrons are accelerated and heated. The primary scientific objective of the Fast Auroral SnapshoT (FAST) Explorer is to study the microphysics of the low‐altitude auroral acceleration region with extremely high time‐resolution.A wide variety of auroral plasma phenomena have been discovered by recent experiments, but are not yet understood in detail. These include electrostatic shocks, small‐scale double layers, electrostatic and electromagnetic ion cyclotron waves, the fine structure of auroral kilometric radiation, counterstreaming field‐aligned electron beams, and upward‐flowing field‐aligned ion beams. In most of these experiments, temporal resolution was limited to the spin period of the spacecraft and ultimately constrained by the capacity of the data systems. Recent sounding‐rocket investigations have found that the plasma of the auroral zone possesses much finer temporal and spatial structures than have been resolved

摘要:
Recent AGU meetings show a dangerous trend in the quality of presentations. A fair percentage of slides used during oral presentations consisted of a black background and colored lines and/or words for data. Such slides are illegible and serve to undercut the speaker's points by not demonstrating the data clearly.A typical example consisted of dark red, dark blue, and green data on a black background. Even the author had difficulty in pointing out the data using his light arrow. Line drawings, in particular, should not use colors, but instead use high‐contrast white‐on‐black for the following reasons: dark colors on black backgrounds provide little contrast, making it difficult to discern patterns; people who are colorblind are at a disadvantage; and the same information can be obtained using a variety of line weights (dotdash, solid, dotted, etc.) with single color s

摘要:
The AGU Hydrology Section's 1991 Robert E. Horton Award was presented to Keith Beven in December at the 1991 Fall Meeting, held in San Francisco. The award honors a “single outstanding contribution to the science of hydrology made during the preceding 5 years
