Tornadoes, the most violent weather phenomena on earth, can occur anywhere in the world. Most, however, happen in the United States in "tornado alley," the states of Texas, Oklahoma, and Kansas. Briefly relates the weather conditions necessary to produce tornadoes. Ride with storm chasers as they pursue these violent storms. Eyewitness accounts, time-lapse photography, and film footage capture the destructive power of tornadoes.

Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on the weather conditions needed to spawn tornados. Part of the Science Video Vocab Series.
The project is called VORTEX2. For five weeks in the spring of 2009, and again in spring 2010, 100 researchers and scientists from 16 universities deployed about 40 vehicles armed with high tech equipment to measure and probe tornadoes and tornado development.
Tornadoes claim hundreds of lives and cause billions of dollars in damages in the United States. With support from the National Science Foundation, computer scientist Amy McGovern at the University of Oklahoma is working to find answers to key questions about tornado formation. While video from storm chasers and data from Doppler radar can help meteorologists understand some aspects of tornadoes, McGovern uses supercomputers to find patterns in very large datasets. She also works with weather experts to help her sort out the information in the simulations. McGovern’s ultimate goal is to come up with reliable tornado forecasting system.
A new generation of smaller, highly capable radar systems in the Dallas/Fort Worth area is able to track with more accuracy the location of tornadoes and other severe weather conditions. These new systems are spaced much closer together than current radar sensors, and the closer proximity is part of the reason the new systems can catch a tornado that could be missed by current radar.

Staying safe in all kinds of weather and avoiding weather-related injuries are the focus of this practical video. Concepts and terminology: lightning, tornado, wind, hurricane, and safe shelter.
Weather is the state of the atmosphere, and it refers to the day-to-day temperature and precipitation activity. The difference between air pressure, temperature, and moisture influence weather-related phenomena. Other topics covered include evaporation, relative humidity, clouds, precipitation, rain gauge, air mass, front, thunderstorm, hurricane, tornado, weather forecast, meteorologist, and satellite imagery.
Superhero Bruce Rain must stop a tornado, a blizzard, and a hurricane. As he races to stop the storms, Dr. Mother Nature explains the relationship between wind and severe weather. Part of "The Science of Climate" series.
A team of storm chasers crisscrosses Tornado Alley in the Midwest in search of the next mega-storm. They have installed new equipment and instruments to study two particular aspects of tornados: hail and lightning. Segment of vide from Wild Chronicles Series.
They are sometimes seen as threatening funnel clouds descending from stormy skies. Others can be nearly invisible, like a ghostly spiral of wind skimming the sea surface. These eerie columns of rotating air are known as waterspouts and are commonly defined as tornadoes over water. Waterspouts usually develop over warm tropical ocean waters. Part of the "Danger Zone" series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko bids farewell to Totemie. As promised, he gives Mei Li's stone and Alarick's flute. She in turn gives him a present that he may only open when he arrives at his destination. One morning, he sees the coast of his land after battling through a tornado! When he gets to shore, he opens Totemie's gift and finds not only her bracelet, but also Mei-Lei's stone and Alarick's flute and realizes that the greatest gift has been meeting his new friends.
For nearly a decade, with support from the National Science Foundation, Doppler on Wheels (DOW) has been doing its best work in dangerous weather to gather scientific data about wind, rain, and snow. Meteorologist Josh Wurman and his team at the Center for Severe Weather Research in Boulder, Colorado coordinate a fleet of storm-chasing vehicles from a compact control room inside one of the DOW trucks. From thunderstorms to blizzards, hurricanes to tornadoes, DOW is providing extensive and detailed information that may ultimately improve warning systems and weather prediction. Part of the National Science Foundation Series “Science Nation.”
Whether they arise from human causes or forces within planet Earth itself, natural disasters threaten life and civilization with what seems to be growing frequency. Studies troubling developments in marine, arctic, wetland, and urban environments while highlighting research opportunities that may help prevent future catastrophes. Coral reef decay, Everglades habitat loss, polar ice disappearance, and global warming are all analyzed. Looks at earthquake prediction, hurricane and tornado tracking, air pollution monitoring, tsunami warning systems, and the cleanup of toxic flood sediment in New Orleans.
What causes earth's weather? Explains that the sun is the primary source of our changing weather phenomena as it warms the atmosphere and water. Covers weather forecasting, high and low pressure fronts, cloud formations, and the water cycle. Presents weather conditions for thunderstorms, tornadoes, and hurricanes.
In this episode, groups of citizen scientists use mobile technology to help save lives. Volunteers across North America measure precipitation, and their data is used by emergency managers to issue warnings during extreme weather conditions. In India, a phone app helps officials alert communities about killer heat waves. Citizen scientists also help collect data about Alzheimer's disease. They hope their data will aid the research process and lead to a cure. Part of "The Crowd and the Cloud" series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is enjoying the seashore on the beach when Mei-Lei comes to get him to go fishing. They sail out into the sea and in the distance Moko sees what looks like a hill. Mei-Lei tells him that is actually a giant wave! All of a sudden, the tsunami lifts their boat high into the air and propels it forward. The wave crashes down and drops their boat right at the entrance to the village. Moko believes that they were kept safe because he knew to trust the ocean.
Provides important steps you can take and become self-reliant to prepare for various emergency situations topics include: Weather-related disasters, hurricanes, tornadoes, blizzards, floods, wildland fires, earthquakes, power outages, terrorism, bio terrorism, pandemics, avian and swine influenza, radiation emergencies, effects of climate change, and other disruptions including civil unrest. Knowing what you and your family can do to prepare for any type of disaster will help reduce stress if a natural or man-made disaster occurs. Having the proper supplies and knowing how to use them can make a difference between life and death in time of an emergency. Explains how to store food and water and you can have hot, tasty meals without electric power.
