Effect of wind turbine generator model and siting on wind power changes out of large WECS arrays [PDF]

, 1981
Methods of reducing the WECS generation change through selection of the wind turbine model for each site, selection of an appropriate siting configuration, and wind array controls are discussed. An analysis of wind generation change from an echelon and a

Evaluation of video evidence of possible ball lightning

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We analyze images of possible ball lightning that appeared less than 10 m from a video camera. The objects' velocity and estimated brightness all agree with typical eyewitness accounts of ball lightning. Though there is an alternative explanation that the objects were sparks from a power‐line arc, we describe analytical techniques that assist in ...

Comparative analysis of ERA5 and Raman lidar‐derived moisture profiles in the framework of the WaLiNeAs field campaigns

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In this paper, we compare atmospheric water vapour data acquired with lidars during the WaLiNeAs programme with data from the ECMWF ERA5 reanalysis. The WaLiNeAs field measurement campaigns took place in autumn/winter 2022/2023 over the French Mediterranean basin and in summer 2023 near Toulouse.

Seasonal forecasting of lightning and thunderstorm activity in tropical and temperate regions of the world

Scientific Reports, 2016
Thunderstorms are convective systems characterised by the occurrence of lightning. Lightning and thunderstorm activity has been increasingly studied in recent years in relation to the El Niño/Southern Oscillation (ENSO) and various other large-scale ...
