Leonardo da Vinci and the Downburst

Bulletin of the American Meteorological Society, 1990
Abstract Evidence from the drawings, experiments, and writings of Leonardo da Vinci are presented to demonstrate that da Vinci recognized and, possibly, discovered the downburst and understood its associated airflow. Other early references to vortex flows resembling downbursts are mentioned.

Numerical Simulation of Downburst Wind Loads

2009 International Conference on Management and Service Science, 2009
Wind hazard is the one which has the widespread influence in the nature disaster. Transmission towers have experienced a number of failures due to downburst wind events in recent years, with devastating economical and social consequences. Based on the mechanism of downburst wind load, the present paper proposes an AR model method of adding turbulence ...

Feedback control for penetrating a downburst

Guidance, Navigation and Control Conference, 1987
Feedback logic is given that produces satisfactory penetration of an aircraft through a severe downburst. The logic has two parts: (1) A switch that calls for full throttle and tight climb-rate-hold feedback logic when the magnitude of headwind-rate exceeds a threshold level; this switch stays on until re-set by the pilot after penetration of the ...

DOWNBURSTS: Meteorological features and wind field characteristics

Journal of Wind Engineering and Industrial Aerodynamics, 1990
Abstract Since the term “downburst” was coined by the author back in 1976, it has been subclassified into “microburst” and “macroburst” according to the horizontal dimension of the wind system. Introduced in this paper is the basic observational evidence of the microburst investigated by three fact-finding projects in 1978, 1982, and 1986, at three ...
