Also, if you see a funnel cloud that does not appear to be touching the ground, the wind This is even greater if employees have families or pets there. Since low pressure systems rotate counterclockwise (and this is due to the Coriolis effect), tornado rotation also tends to be inherited from the low pressure systems. The researchers also found that when approaching a geographic intersection, tornadoes climb toward ridges rather than go downhill, which is counterintuitive when one thinks about wind or water seeking the path of least resistance. In the United States, there are over 1,000 tornadoes recorded each year. While vehicles are one of the most dangerous places to be during a tornado, underneath an overpass may be the only place thats worse. However, tornadoes can happen almost anywhere.
