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.

Sea spray aerosols occur naturally in the salty ocean air, and there’s much more in each of those tiny bursting bubbles than salt. They’re bursting with ocean life, from bacteria to phytoplankton--even viruses. Because sea spray aerosols seed clouds, they affect the climate. With support from the National Science Foundation (NSF), atmospheric chemist Kimberly Prather of the University of California, San Diego, and chemist Vicki Grassian of the University of Iowa are leading a team of scientists around the country who are working to better understand what role sea spray aerosols play in weather and climate change climate models. Part of the National Science Foundation Series “Science Nation.”
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.
A volcanologist explores the fiery landscape of Iceland. Segment of video from Wild Chronicles Series.
Explore how the nature of highly seasonal rainfall cycles and periodic fires create conditions that have shaped Mediterranean-climate ecosystems. Part of the "Mediterranean-Climate Ecosystems" series.
Not only can lightning strike twice, but it can also strike the ocean. Individuals must take certain safety measures when surrounded by water during a storm. Part of the "NOAA Ocean Today" series.
Learn about the Voyager 2 mission to Neptune in this video from NASA. Voyager 2 reached Neptune in 1989 and discovered the planet appears due to the methane in its atmosphere. The mission also revealed Neptune has at least four rings, six moons, and an interesting weather system.
Introduces students to our planet Earth and its place in the solar system. Explains that Earth's unique position makes it conducive to life. Also explains the basics of earth science, including the water cycle, weather, and continents. Short review.
The gardeners work to prepare the orchard. They manage the orchard through all the seasons to ensure the best quality of fruit in the spring and summer. Part of the "Four Seasons in the Garden" series.
When the city is hit by a colossal snowstorm, only one superhero can save the day. But who is this mysterious hero, and why does he disappear once his job is done? Based on the children's book by Stephen Savage.
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 geological causes of a tsunami and their devastating effects on land and people. Part of the Science Video Vocab Series.
Hurricanes are one of the most powerful and destructive forces on Earth. How do they form? The formation of a hurricane is complicated, but basically, it depends on 3 factors: warm water, moist air, and converging winds. Part of the "Danger Zone" series.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on assigning organisms to the correct family as outlined by the scientific classification system. Part of the Science Video Vocab series.
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.
Drawing upon the American Geological Institute's huge geoscientific archive of information, this segment explores the hydrosphere and the atmosphere. It also covers their formation and components, the water cycle, geological evidence of past climate change, extreme weather, and the future of the fluid spheres. Part of the "Visions of Earth" series.
Characteristics of the Mediterranean climate include great weather, abundant harvests, and some of the world’s most cosmopolitan cities. These climate zones also house diverse ecosystems, which are dependent of the geology of the regions. Part of the "Mediterranean-Climate Ecosystems" series.
There are four categories of climate types found around the world and discusses the similarities and differences among them. This program examines cold climate areas, temperate climate regions, dry climates, and equatorial warm and humid climates.
The Earth has many land formations such as mountains, plateaus, hills, and plains. These formations are created by movement of the earth’s plates, volcanoes, weather, and erosion. Part of the Real World Science 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.
Live-action, colorful footage illustrates the exciting, natural highlights of summer. Activities of plants and animals during the summer season are explored. Additional concepts and terminology include: growth, development, seeds, food storage, recreation, and solstice.
