A formula is obtained for calculation of wind speed in tornado, as proportional to the speed of convective updraft. Results are presented of wind speed calculation using the formula for 57 tornadoes observed at different time and in different regions of the world. Possibilities are shown of ...
A wind farm in southwest Iowa suffered a direct hit from a powerful tornado that crumpled five of the massive power-producing towers, including one that burst into flames.
The Joplin, Missouri tornado of 2011 occurred on May 22, shortly after 5:30 pm CDST on a Sunday evening. The danger to the public was compounded by the tornado being rain-wrapped and occurring around the time that large graduation ceremonies ended with attendees traveling home....
“When you do a design, you don’t design something that can withstand an EF4 or EF5 tornado,” Sritharan said. Article content Wind turbines are designed to meet industry standards for structural integrity that includes factors like wind speed, and it’s possible that de...

across a pressure gradient (from high to low), it generates a certain amount of force. If there is a high-pressure area and a low-pressure area very close to one another, the pressure gradient will be high, the air will shift locations more forcefully, and wind speed will increase ...

Is there an optimal ENSO pattern that enhances large-scale atmospheric processes conducive to major tornado outbreaks over the U.S.? Observations and modeling experiments are used to show that a positive phase of Trans-Ni帽o, characterized by cooling in the central tropical Pacific and w... S...
For comparison, wind data were collected with an ultrasonic anemometer, which was located on the mast of the RP Flip. All wind measurements were converted to a 10-min mean wind covering wind speeds between 4 and 22 m/s. In Figure 1(a), the wind speed dependency of the radar backscatter...
