What does it mean when you dream about a tornado?
Dreams about tornadoes may indicate issues or conditions that make one feel overwhelmed and out of control. There may well be repressed rage. Tornadoes can also reflect some sort of tremendous upset in the immediate environment.

(programming)VxWorks
A popular real-time operating system for embedded systems from Wind River, Alameda, CA (www.windriver.com). It is used to control a wide variety of products, including network and telecom devices, test and measurement equipment, computer peripherals and consumer products. It is also used in the automotive and aerospace industries for engine control and avionics. Available for a large number of CPU types, applications are created in Wind River's Tornado development environment.VRTX Roots
VxWorks was originally an extension of the VRTX real-time OS kernel. Wind River added a file system and integrated development environment (IDM) that made the VRTX operating system "Work"able. Later, the VRTX kernel was rewritten. See VRTX.
Tornado
(dreams)Tornado
an atmospheric vortex that originates in a cumulonimbus cloud and then reaches toward the surface of land or sea, assuming the shape of a dark hose or snout. Its upper part exhibits a funnel-shaped widening that blends with the clouds. When a tornado descends to the land surface, its lower part also expands and resembles an inverted funnel. The height of a tornado may attain 800–1,500 m. Air within a tornado usually rotates in a counterclockwise direction, simultaneously rising upward in a spiral and sucking in dust and water; the velocity of rotation is several tens of meters per second. In connection with the lowering of air pressure inside the funnel, there is condensation of water vapor. The water vapor, as well as the funnel cloud, dust, and water, makes the tornado visible. The diameter of a tornado above sea is measured in tens of m, and above dry land in hundreds of m.
A tornado usually originates in the warm sector of a cyclone, most frequently in advance of a cold front. It travels in the same direction as the cyclone, which moves at a rate of 10–20 m/sec. While in existence, a tornado travels a path of 40–60 km. The formation of tornadoes is associated with extremely unstable atmospheric stratification.
Tornadoes are accompanied by thunderstorms, rain, and hail. They almost always cause large-scale destruction when sweeping the ground because they draw in water and objects in their path; they are lifted to considerable heights and moved over great distances. Tornadoes formed at sea, which are called waterspouts, pose a grave danger to ships. Tornadoes over dry land are sometimes called twisters.
