Wind has become increasingly important as a source of energy although the generation of wind energy is quite erratic because of its changeable nature. For a given location, wind speed and direction change over time and at different heights. Previous studies have discovered different pattern of wind profiles, however an improved understanding of its spatial, temporal and variation in heights is ...

in this paper, the 10-minutes period measured wind speed data at different heights (10 m, 30 m, and 40 m) are presented for khvaf, which is one of the major counties with high wind potential in khorasan provinces in iran. to the author’s knowledge, there hasn’t been any assessment works in the mentioned site. from the primary evaluation and by determining mean wind speed and also the weibull fu...

The weather forecast by satellite data is a good guideline for assessment of voyage planning route in order to have safe and economic voyage for shipping. ISO15016, "Guidelines for the assessment of speed and performance by analysis of speed trial data", has been developed by the working group ISO/TC 8/SC 9/WG 2. This paper presents the effects of wave speed & direction, wind speed and directio...

The problem of detecting changes in wind speed and direction is considered. Bayesian priors, with various degrees of certainty, are used to represent relationships between the two time series. Segmentation is then conducted using a hierarchical Bayesian model that accounts for correlations between the wind speed and direction. A Gibbs sampling strategy overcomes the computational complexity of ...

The Viking Landers measured pressure, wind speed and direction, and air temperature with a small boom [1]. Mars Pathfinder had the Atmospheric Structure Instrument on its lander and recorded pressure, air temperature and wind direction [2]. MSL has environment sensors within its payload as well: it is the REMS (Rover Environmental Monitoring Station) instrument, which is in charge of recording ...

We describe radar measurements of waves, currents and winds made on the coast of northern Scotland during two 2013/14 winter storms, giving methods, results and interpretation. Wave parameters (height, period, direction and short-wave/wind direction) were derived and compared with measurements made by a neighboring buoy and local weather stations. Wind direction and current velocity maps were p...
