Study Finds Wind Speeds Decreasing in US
A unique study soon to be published in the Journal of Geophysical Research offers preliminary findings that point toward decreasing wind speeds throughout the United States. The study suggests that average and peak wind speeds have been noticeably slowing since 1973, especially in the Midwest and the East, with a 10% or more drop in the past decade. Ohio, Indiana, Michigan, Illinois, Kansas, Virginia, Louisiana, Georgia, northern Maine and western Montana have experienced the biggest decreases in wind speeds.
Although there is not a definitive connection, scientists speculate that climate change may be the culprit. With polar regions warming, the difference in temperature variation between the poles and the equator is decreasing. As temperture differences decrease so do differences in barometric pressure, a main contributor to strong winds. For more information, see Scientific American.
