Characterization of CYGNSS Ocean Surface Wind Speed Products

Remote Sensing
Since its launch in 2016, a number of wind speed retrieval algorithms have been developed for the NASA CYGNSS satellite observations. We assess their accuracy and precision and characterize the dependence of their performance on environmental factors ...

Projected Near-Surface Wind Speed Trends in Lithuania [PDF]

Energies, 2021
Developing wind energy in Lithuania is one of the most important ways to achieve green energy goals. Observational data show that the decline in wind speeds in the region may pose challenges for wind energy development. This study analyzed the long-term variation of the observed 2006–2020 and projected 2006–2100 near-surface wind speed at the height of

Response Surface Optimisation of Vertical Axis Wind Turbine at low wind speeds [PDF]

Energy Reports, 2022
The Vertical Axis Wind Turbines (VAWTs) have an increasing global market and this emphasis the need for to improve the performance of VAWTs, especially at relatively low wind speed. This paper utilises the Response Surface methodology to optimise the performance of a VAWT. A three bladed VAWT configuration was considered with a NACA0015 profile.

Observed near‐surface currents under high wind speeds [PDF]

Journal of Geophysical Research: Oceans, 2012
From the Surface Velocity Program (SVP) drifter current and QuikSCAT wind data, the relationship between the observed near‐surface current vectors and surface wind vectors for the northwestern Pacific Ocean under high winds (20–50 m s−1) are obtained with quantitative estimations of near‐surface drift ratio (current speed versus wind speed)r(∼2%) and ...

Parameterizing surface wind speed over complex topography [PDF]

Journal of Geophysical Research: Atmospheres, 2017
AbstractSubgrid parameterizations are used in coarse‐scale meteorological and land surface models to account for the impact of unresolved topography on wind speed. While various parameterizations have been suggested, these were generally validated on a limited number of measurements in specific geographical areas. We used high‐resolution wind fields to

A global climatology of wind–wave interaction [PDF]

, 2010
Generally, ocean waves are thought to act as a drag on the surface wind so that momentum is transferred downwards, from the atmosphere into the waves.

Influence of Topography and the Underlying Surface of the Bohai Sea on Wind and Gust Forecasts

Earth and Space Science, 2023
Accurate gust forecasts can reduce potential threats to people's lives and properties, but we need more reliable forecasting methods and models. A recent development is the meteorologically stratified gust factor (MSGF) model, which is more accurate in ...

Standardization of Offshore Surface Wind Speeds

Journal of Applied Meteorology and Climatology, 2016
AbstractWind measurement offers an essential data source for a wide range of practices in the fields of meteorology and wind engineering. However, records of surface winds are usually influenced by terrain/topographic effects, and direct usage of raw data may bring in nonignorable errors for follow-up applications.
