THE recent correspondence in NATURE upon this subject ought not to close without some reference to a possible explanation of soariiig which does not appear to have been yet suggested. 
Dynamic Soaring Kinetic Energy Reference Frames
Dynamic soaring in the boundary layer of a vertical variation of horizontal wind offers unmanned aerial vehicle gliders the ability to greatly extend mission endurance. By flying periodic trajector...
Novel Approach to Dynamic Soaring Modeling and Simulation
This paper revisits dynamic soaring on the basis of a nonlinear point-mass flight dynamics model previously used for scale-model aircraft to design path-following autopilots endowed with theoretica...
Multiple Thermal Updraft Estimation and Observability Analysis
TLDR
A particle-filter-based method is proposed, which allows estimating position, strength, and characterization of multiple thermal updrafts using a particle- filter-based approach.

Dynamic soaring is flight sustained through the power gained by coordinated manoeuvering in wind gradients. These wind gradients can be horizontal, as caused by wind shear, and relevant to the mode
Optimal dynamic soaring consists of successive shallow arcs
TLDR
This analysis constitutes a general framework for dynamic soaring and more broadly energy extraction in complex winds, geared to improve the characterization of pelagic birds flight dynamics and habitat, and could enable the development of a robotic albatross that could travel with a virtually infinite range.
Across landscapes and seascapes : The movement ecology of diving and flying guillemots and gulls during breeding
TLDR
I followed five species across two sites in Sweden in the Baltic Sea using GPS and time-depth recorder devices, giving information on both flight and diving activity, to test theories of how birds should optimally vary their flight behaviour in response to winds and of how individual birds collect information on alternative breeding sites, i.e. prospecting.
The influence of wind shear to the performance of high-altitude solar-powered aircraft
There is a greatly persistent wind shear in the upper atmosphere, especially at the altitude of 10–20 km. For the idea of dynamic soaring, the wind shear can be treated as a kind of energy resource
Optimization of dynamic soaring in a flap-gliding seabird affects its large-scale distribution at sea.
Dynamic soaring harvests energy from a spatiotemporal wind gradient, allowing albatrosses to glide over vast distances. However, its use is challenging to demonstrate empirically and has yet to be
Optic flow cues help explain altitude control over sea in freely flying gulls
TLDR
It is concluded that the optic flow regulation principle helps gulls to adjust their altitude over sea without having to directly measure their current altitude.
Dynamic soaring mechanisms in the ocean boundary layer
Dynamic soaring is a flying technique which extracts energy from an environment where wind gradients form, such as the air-sea interface above oceans that sees such gradients developing through
