Atmospheric scientists conduct field experiment to study wind flow over complex mountain terrain
Atmospheric scientists conduct field experiment wind flow over complex mountain terrain
2017/7/21
Over the past month, researchers have descended on Portugal's Vale Do Cobrão near the Spanish border to study the valley's wind flow patterns.The international project, known as Perdigão aft...
The western United States relies on mountain snow for its water supply. Water stored as snow in the mountains during winter replenishes groundwater and drives river runoff in spring, filling reservoir...
