Review this article on the device used in the movie Twister to calculate the science of a tornado: Twister: Dorothy PDF . Understanding the science behind a tornado can help people identify more appropriate warning signs regarding the development of this massive storm. Discuss how we know what we know about tornadoes? For instance, in the movie Twister ( Twister - Dorothy IV Launched Video , the captioned version of this video can be found here , the transcript of this video can be found here ), Dorothy is used as a device to collect data on the tornado. What is this device created to measure in terms of the atmosphere? What do we learn from this device according to the article and how does that information help us? In responding to your peers, what instruments are used today to discover information about other wind storms such as hurricanes? Identify and explain one for your peers' review. Most of what we know about tornados has been contributed by theoretical contributions, field observations and computer simulations with two of the most prevalent experimental projects being the VORTEX and VORTEX2 projects (Verification of the Origins of Rotation in Tornadoes Experiment). These experiments, in congruence with doppler radar observations and field measurements, have brought forth considerable data with which scientists have been able to accomplish an understanding of this weather phenomena. Most predictions/warnings of tornados that occur today are done so by observing supercell thunderstorms via Doppler radar and computer algorithms, which detect certain velocity patterns that indicate intense concentrated rotation known as a Tornado Vortex Signature (TVS). Although TVS does not guarantee a tornado as much as it represents a strong increase in the probability of one occurring, it has been an extremely useful tool in continued data collection and enables the warning systems we have in place today. (NSSL, n.d. & Markowski & Richardson, 2014)  Since TOTO utilizes anemometers, pressure sensors and humidity sensors, the device can measure an array of phenomena within a tornado. Anemometers are used to measure the speed or velocity of gases, specifically horizontal wind speed, and can essentially determine the wind
speed within the tornado itself, potentially observing the varying wind speeds from the bottom of the funnel to the top. Humidity sensors would be able to measure the saturation within the tornado, perhaps indicating a specific humidity range that would contribute to tornadic weather. Thirdly, the pressure itself within the tornado could be measured via the pressure sensors, indicating the low pressure within the storm and just how much that varies from the low pressure system the tornado forms from. By utilizing the data collected by these instruments, it could potentially determine a 'sweet spot' in which these tornados are most prone to form, enabling far better predictions on when and if they would form and reduce false warnings.
