Downbursts can be a significant hazard to aviation safety as well as to agricultural activities, structures and buildings on the ground. Major damages on the surface, airline incidents in the past, worns on the mechanism of the downburst occurrence and recent efforts to detect eho downburst are reviewed.

Preliminary study on the causes of a downburst event in Tianjin in the summer of 2017
A severe thunderstorm gale event with several short-term rainfall,hail and downburst occurred in the southwest of Tianjin on 9 July 2017, during which two downbursts attacked successively Duliu Town,Jinghai District,Tianjin.

Automated Recognition of Macro Downburst Using Doppler Weather Radar
In light of the macro downburst’s ground divergent flow field characteristics and high reflectivity, this paper proposes an algorithm for identifying the downburst area using a Doppler weather radar low-level radial velocity and reflectivity factor ...

Semiempirical Models of Speedup Effect for Downburst Wind Field over 3-D Hills
Downbursts occur frequently in mountainous regions, such as the southwest of China, and causing extensive damage to engineering structures. While some researchers have developed semiempirical models for the speedup effect, most are based on the wind ...

Oklahoma Downbursts and Their Asymmetry
Abstract Doppler radar data collected each spring in 1979–1984 with the two Doppler radars operated by the National Severe Storms Laboratory (NSSL) are used to investigate the asymmetry of low-altitude divergent outflows of convective storm downbursts in central Oklahoma.

Using crop fall patterns to provide an insight into thunderstorm downbursts [PDF]
This paper examines whether crop fall patterns due to thunderstorm downburst-like events can provide an insight into the flow structure of a downburst. To explore this phenomenon, a novel three-dimensional analytical model for the velocity flow field is ...

The influence of thunderstorm downbursts on wind turbine design [PDF]
textThe International Electrotechnical Commission (IEC) standard 61400-1 for the design of wind turbines does not explicitly address site-specific conditions associated with anomalous atmospheric events or conditions.

Thunderstorm Downbursts and Wind Loading of Structures: Progress and Prospect
In 1961, Davenport published a paper, considered by most to be a critical work in the study of wind engineering, in which meteorology, micrometeorology, climatology, aerodynamics, and structural dynamics were embedded in a homogeneous framework of the ...

Computational simulation of thunderstorm downbursts and associated wind turbine loads [PDF]
textWind turbines operate in a constantly changing wind environment. This requires modeling and simulation of extreme events in which the wind turbine operates and a study of associated turbine loads as part of the design practice and/or site assessment.
