Earth and Space ScienceAbstractThis study investigates lightning at tall objects and evaluates the risk of upward lightning (UL) over the eastern Alps and its surrounding areas. While uncommon, UL poses a threat, especially to wind turbines, as the long‐duration current of UL can cause significant damage.

Difference Between 2D and 3D Development Characteristics of an Upward Lightning Leader
应用气象学报, 2023 Tall object not only has a high probability of being struck by downward lightning, but also is easy to trigger upward lightning. Comparing with 2D optical observation, reconstructed 3D observation by dual-station optical observation can better reflect ...

ADAPTIVE HIERARCHICAL DENSE MATCHING OF MULTI-VIEW AIRBORNE OBLIQUE IMAGERY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 Traditional single-lens vertical photogrammetry can obtain object images from the air with rare lateral information of tall buildings. Multi-view airborne photogrammetry can get rich lateral texture of buildings, while the common area-based matching for ...

Monitoring the Geometry of Tall Objects in Energy Industry
Energies, 2022 The landscape shaped by the energy industry is rich in various slender structures, such as smokestacks, cooling towers, and others. It is thus becoming increasingly important to effectively monitor the geometrical condition of all types of such structures. Slender structures are deformed elastically under loads due to wind.

Initial stage in lightning initiated from tall objects and in rocket‐triggered lightning [PDF]
Journal of Geophysical Research: Atmospheres, 2005 We examine the characteristics of the initial stage (IS) in object‐initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket‐triggered lightning in Florida.

Transient response of a tall object to lightning [PDF]
IEEE Transactions on Electromagnetic Compatibility, 2001 Experimental data showing the transient behavior of tall objects struck by lightning are reviewed. The influence of this transient behavior, illustrated by simple calculations, on measured lightning current and measured remote electromagnetic fields is discussed.

Does planning a different trajectory influence the choice of grasping points? [PDF]
, 2010 We examined whether the movement path is considered when selecting the positions at which the digits will contact the object's surface (grasping points).
