U.S. May 2023 Wind Speeds Below Normal Due to -SOI

During May 2023 U.S. wind power generation was below normal on both zonal and meridional directional scales. Wind power generation areas across the Upper Midwest/Midwest U.S. and southwest Great Plains/Western Texas were each affected by the lighter than normal wind speed regimes. The macro-scale driver of the lighter wind speeds was an El Nino-like climate as defined by a vigorous negative phase of the southern oscillation index.

Lack of Wind for SPP/ERCOT in May So Far

So far, May 2023 has produced below normal zonal and meridional wind speeds across the U.S. particularly across most of the SPP and ERCOT regions of the Central U.S. Causal to the lack of wind is a large area of high pressure over Western Canada extending to the Great Plains and generally weak low pressure in the far southern States to the East Coast.
