A New Cyclic Iterative Correction Algorithm for Retrieving Sea Surface Wind Speed Based on a Multilayer-Medium Model

open access: yesIEEE Access, 2022
At high sea conditions, e.g., typhoons and hurricanes, the sea surface waves break and produce foams, spray droplets, and bubbles, which are collectively known as whitecaps.

Research on neural network wind speed prediction model based on improved sparrow algorithm optimization

open access: yesEnergy Reports, 2022
The wind speed signal measured by the mechanical anemometer lags behind the wind speed at the wind wheel surface of the wind turbine in time. The wind speed reconstruction algorithm adopted by the ordinary lidar anemometer is insufficient.

Quantifying wind and pressure effects on trace gas fluxes across the soil–atmosphere interface [PDF]

open access: yesBiogeosciences, 2015
Large uncertainties persist in estimates of soil–atmosphere exchange of important trace gases. One significant source of uncertainty is the combined effect of wind and pressure on these fluxes. Wind and pressure effects are mediated by surface topography:
