Microburst characteristics determined from 1988-1991 TDWR testbed measurements [PDF]
This paper presents some recent results germane to airborne windshear system design and certification. We first discuss the data analysis procedure and the associated caveats.

Journal of Geophysical Research: Space Physics, 2017 Relativistic electron microbursts are frequently observed during high‐speed solar wind stream (HSS) events. However, solar wind parameters, which are important for enhanced microburst precipitation, have not been well understood.

Observational Evidence for Three Time‐Scale Modulations in the Pulsating Aurora
Geophysical Research LettersWe report an Arase‐all sky imager (ASI) conjugate event in which the pulsating aurora (PsA) has a one‐to‐one correspondence with chorus bursts. Wavelet analysis displayed three peaks at ∼0.3 Hz, 4 Hz, and >10 Hz, corresponding to the main pulsation ...

Analysis and modeling of microburst precipitation
Geophysical Research Letters, 1996 Observations from a recent rocket experiment that measured electrons over the energy range of 1–300 keV shows that microburst temporal structures exist from about 20 keV to >120 keV. Simultaneous observations at five different pitch‐angles (0°–90°) show the distribution is nearly isotropic during the bursts, while at low activity (quiet times and ...

Severe Convection at Burgas Airport: Case Study 17 September 2022
Remote SensingConvection monitoring and forecasting are crucial for air traffic management as they can lead to the development of intense thunderstorms and hazards such as severe turbulence and icing, lightning activity, microbursts and hail that affect aviation ...

Optimization of aircraft trajectories through severe microbursts [PDF]
A method of defining performance envelopes for aircraft microburst penetration is being developed. A trajectory is computed for a given aircraft/control law configuration and given microburst parameters (either a downdraft or a head/tailwind type ...

Alert generation and cockpit presentation for an integrated microburst alerting system [PDF]
Alert generation and cockpit presentation issues for low level wind shear (microburst) alerts are investigated. Alert generation issues center on the development of a hazard criterion which allows integration of both ground based and airborne wind shear ...

Cockpit display of hazardous wind shear information [PDF]
Information on cockpit display of wind shear information is given in viewgraph form. Based on the current status of windshear sensors and candidate data dissemination systems, the near-term capabilities for windshear avoidance will most likely include ...

VHF discharges in storm cells producing microbursts [PDF]
An experiment was carried out in which 3-D mapping of VHF sources was compared to a 3-D description of the reflectivity and dynamics of associated cloud cells observed by a radar network.
