Directional Modelling of Extreme Wind Speeds

Applied Statistics, 1994
Summary: Extreme value models play an important role in assessing the risk to buildings caused by high wind speeds. However, standard procedures take no account of the directional behaviour of the wind. In this paper the extremal properties of the wind process are modeled as a function of direction. This requires the adaptation of techniques which have

Joint segmentation of the wind speed and direction

Signal Processing, 2006
We present in this article a Bayesian estimation method for the joint segmentation of a set of piecewise stationary processes. The estimate we propose is based on the maximization of the posterior distribution of the change instants conditionally to the process parameter estimation.

Wind and the Direction of Nocturnal Songbird Migration

Nature, 1970
MIGRATING birds do not seem to be drifted off course by light to moderate unfavourable winds1–4. Birds tend to migrate with tail winds, and various people have proposed that the migrants reduce chances of drift by selecting following winds for their particular goal-directed flights.

The Response of Wave Directions to Changing Wind Directions

Journal of Physical Oceanography, 1987
Abstract From the premise that the net growth of wave energy induced by wind is centered around the wind direction, a relaxation model for the response of the main wave direction to changes in the wind direction for young sea states is derived. The time scale of this relaxation model is found to be equal to the time scale of the wave energy growth.

Directional analysis of SAR images aiming at wind direction

IEEE Transactions on Geoscience and Remote Sensing, 2004
Currently, the retrieval of wind fields from synthetic aperture radar (SAR) images suffers from inadequate knowledge of the wind direction. State-of-the-art spectral analysis works fine on open seas, but is limited in spatial resolution. The method described here is based on the local gradients computed with standard image processing algorithms.

Directional distribution of chilling winds in Estonia

International Journal of Biometeorology, 2015
Wind chill equivalent temperature (WCET) is used to define thermal discomfort in winter months. Directional distributions of winds, which are associated with uncomfortable weather, were composed of three climatologically different Estonian locations: Vilsandi, Kuusiku, and Jõhvi. Cases with wind chill equivalent temperature

Indicating Wind Direction Using a Fan-Based Wind Display

2012
Recently, several virtual reality (VR) systems that use wind to enhance users' sensation of presence have been built. In typical systems, wind sources (mostly fans) are arranged rather sparsely around the user. If the fans are arranged more densely, the system can provide a more precise expression of wind direction.
