Estimating omnidirectional urban vertical wind speed with direction-dependent building morphologies A main external factor that limits the energy assessment of high-rise buildings in urban areas is the vertical wind conditions. Conventional buildings' ene... Qi Li,Jiayu Chen,Xiaowei Luo - Energy and ...

Tornado - Wind Speed, Vortex, Destruction: Fully developed tornadoes contain distinct regions of airflow. As is shown in the figure, the central axis of circulation is within the core region, a roughly cylindrical area of lower atmospheric pressure that

Wind is among the most important climatic elements. Its characteristics are determinant for a wide range of natural processes and human activities. However, ongoing climate change is modifying these characteristics, which may have important implications. Climatic changes on wind speed and direction, wind...
