This paper presents atmospheric Shear Wind phenomena models and develops a Particle Filter estimator to characterize the phenomena. We describe a model for the Surface Shear Wind and another for the Layer Shear Wind. The models are described and adjusted for Besian estimation. A Particle Filter was implemented and tested in simulation for Surface Shear

Abstract : Chapter 1 describes the background of the wind shear measuring technique. Chapter 2 describes the mechanical construction of the wind shear probe and gives some of the design criteria for the various sensors. Also described is the instrumentation package which contains the telemetering link and the electronic circuits necessary to measure ...

Shearing wind helicity and thermal wind helicity
Advances in Atmospheric Sciences, 2006Helicity is defined as H = V · ω, where V and ω velocity and vorticity vectors, respectively. Many works have pointed out that the larger the helicity is, the longer the life cycle of the weather system is. However, the direct relationship of the helicity to the evolution of the weather system is not quite clear.

On the Classification of Vertical Wind Shear as Directional Shear versus Speed Shear
Weather and Forecasting, 2006Abstract Vertical wind shear is commonly classified as “directional” or “speed” shear. In this note, these classifications are reviewed and their relevance discussed with respect to the dynamics of convective storms. In the absence of surface drag, storm morphology and evolution only depend on the shape and length of a hodograph, on ...

Smoke transport by sheared winds
Combustion Theory and Modelling, 1999The effect that the wind's vertical variation has on fire plume behaviour is investigated. A parabolized set of governing equations are discretized using finite differences to arrive at the numerical model. Lagrangian particles are used to visualize the flow, account for atmospheric fluctuations and determine the smoke concentration field. A parametric
