Microbursts: a hazard for aircraft

Nature, 1985
Microbursts are believed to have been responsible for several aircraft accidents in recent years. We report here laboratory experiments which show that when a descending column of dense fluid reaches the ground and begins to spread out horizontally, an intense vortex with a horizontal axis forms at the leading edge of the outflowing air.

Relativistic electron microbursts

Journal of Geophysical Research, 1992
We report the first satellite observations of relativistic (>1 MeV) electron precipitation in microbursts with measured durations of less than 1 s. Microbursts of lower‐energy electrons (10–100 keV) have been found to occur preferentially in the early daylight hours and to be closely associated with VLF chorus emissions.

Occurrence characteristics of relativistic electron microbursts from SAMPEX observations [PDF]

Journal of Geophysical Research: Space Physics, 2017
We study the occurrence of relativistic microbursts observed by the Solar Anomalous Magnetospheric Particle Explorer (SAMPEX) satellite. An algorithm is used to identify 193,694 relativistic microbursts in the > 1.05 MeV electron fluxes occurring across ...

Relativistic Electron Microbursts as High‐Energy Tail of Pulsating Aurora Electrons [PDF]

Geophysical Research Letters, 2020
オーロラの明滅とともに、宇宙からキラー電子が降ってくることを解明. 京都大学プレスリリース. 2020-11-13.In this study, by simulating the wave‐particle interactions, we show that subrelativistic/relativistic electron microbursts form the high‐energy tail of pulsating aurora (PsA).

Microburst Teaching and Learning

Medical Teacher, 2001
Amidst changes in the health care field with requirements for increased efficiency and limited time for teaching, there is a need for a teaching-learning model which maximizes the learning process and is exciting, fun, and motivating for both teacher and learner. Microburst Teaching and Learning is one strategy for combining various teaching styles and

Escaping a microburst with turbulence

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
This paper compares three escape strategies for microburst encounters during final landing approach: altitude guidance, dive guidance, and pitch guidance. In the paper, two different approaches are used for comparison. 1) In a sample analysis approach, typical samples of the time histories of various variables are analyzed. 2) In a statistical approach,

Microbursts

International Journal of Information and Communication Technology Education, 2012
The authors examine the Microburst Framework and the literature on Cloud and Mobile Computing with a focus on the educators’ thinking processes and the power of the constructivist learning environment interactions. The Microburst Framework is designed to address the increased thinking processes needed in Cloud and Mobile computing, and is based upon ...
