Microbursts observed at Clark Lake

Advances in Space Research, 1986
Abstract Microbursts are low brightness temperature burst observed by the Clark Lake radioheliograph. The bursts are seen at the observing frequencies from 30 MHz to 70 MHz, are stationary at a given frequency, and have short rise times and durations of 2 – 10 seconds.

Microburst Rotation: Simulations and Observations

Journal of Applied Meteorology, 1995
Abstract Microburst rotation can be determined by measuring the difference in azimuths between the maximum approaching and maximum receding velocity centers on a Doppler radar. Nonrotating microbursts would have these centers exactly along the same radial from the radar.

Dynamics of experimentally simulated microbursts

AIAA Journal, 1995
Laboratory-simulated microbursts are used to study the behavior of buoyancy-driven downdrafts and their associated low-altitude wind shears. The microburst flowfield is simulated by releasing an axisymmetric volume of heavy liquid into a less dense ambient surrounding and allowing it to impinge on a horizontal surface. Using particle image velocimetry,

Aircraft performance in a JAWS microburst

Journal of Aircraft, 1985
A dangerous sequence of events (headwind/downdraft/tailwind) occurs when an aircraft penetrates a microburst at low levels. A prime objective of the Joint Airport Weather Studies (JAWS) project was to quantify the event so that realistic wind shear profiles would be available for computer and manned-flight simulation of aircraft performance in ...

ELMO: ELectron Microburst Observatory mission to study microbursts

We describe the ELectron Microburst Observatory mission, ELMO  which is proposed as  aCubeSat constellation mission to fully characterize microburst event spatial extent systematically for the first time both in latitude  and longitude. ELMO comprises 4 CubeSats two per orbit plane in two orbit planes. ELMO will fly in a high

Application-driven Reexamination of Datacenter Microbursts

ACM SIGMETRICS Performance Evaluation Review
Microbursts are microsecond-scale congestion events that have a severe negative impact on the performance of datacenter networks. Despite various methods proposed to mitigate microbursts, recent studies show that microbursts and their negative effects still persist in datacenters.

Dynamics and Fine Structure of a Microburst

Journal of the Atmospheric Sciences, 1990
Abstract Details of the structure of a moderate reflectivity microburst were provided by dual-Doppler radar measurements during the Phoenix II convective boundary layer experiment. The dated allowed high resolution of the descending microburst in both time and space.

Turbulence structure in microburst phenomena

Journal of Aircraft, 1987
The efect on turbulence of a variable mean wind along the flight path of an aircraft is modeled and analyzed. It is found that the effect of a variable head or tail wind alters the magnitude of the length-scale of sensed microburst turbulence, rendering turbulence more random than usually encountered in the upper atmosphere.
