Space weather can have important consequences for everyday life, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation. The United States Geological Survey (USGS) Geomagnetism Program monitors variations in the Earth's magnetic field through a network of 14 ground-based observatories around the United States and its territories, providing data in real-time to a variety of customers.

Anyone who has ever driven in freezing rain knows all too well the potential hazards of an ice storm. These powerful winter weather events are also capable of catastrophic impacts on forest ecosystems. Syracuse University bio-geochemist Charley Driscoll and U.S. Department of Agriculture (USDA) Forest Service ecologist Lindsey Rustad are part of a team to monitor how a forest ecosystem responds to and recovers from ice storms. Part of the “Science Nation” series.
Hurricane season runs from June to November. During these months, all three requirements for hurricanes to form are present. Storms form off the coast of Africa and travel on currents of warm ocean water. Also, the wind patterns alter the location of the jet stream. Part of the "Seasonal Science" series.
NOAA's environmental satellites provide data from space to monitor Earth to analyze coastal waters, relay life-saving emergency beacons, and predict and track tropical storms and hurricanes. NOAA operates three types of satellite systems for the United States: polar-orbiting satellites, geostationary satellites, and deep space satellites. Polar-orbiting satellites circle Earth and provide global information from 540 miles above Earth. Geostationary satellites constantly monitor the Western Hemisphere from around 22,240 miles above Earth. The deep space satellites orbit one million miles from Earth, providing space weather alerts and forecasts while also monitoring the amounts of solar energy absorbed by Earth every day.
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.
Hubble has studied all of the planets in the solar system except Mercury. Some of Hubble's notable accomplishments include observations of the climate of Venus, dust storms on Mars, the impact of a comet on Jupiter, the rings of Saturn and Uranus, Neptune's immense storms, and dwarf planets such as Pluto, Ceres, and Eris.
Superhero Autumn Ray must stop a storm before it destroys crops and damages property. As she works to stop the storm, she also explains how storms form. She and Dr. Mother Nature also discuss the different types of clouds. Part of "The Science of Climate" series.
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.
What is a thundersnow storm? Most snow storms form when warm air moves into an area in the winter and rising warm air condenses to form snow. If the warm air rises very quickly, the condensing moisture collides with existing particles in the cloud causing electrically charged areas. When a cloud has charged areas, lightning can result. The accompanying sound is why scientists call these thundersnow storms.
With support from the National Science Foundation (NSF), Forrest Masters and a team at the University of Florida are developing new technologies to help engineers and scientists better understand the strong, high-wind storms that batter communities along U.S. coastlines. The National Home Education Research Institute (NHERI) has the broad goal of supporting research that will improve the resilience and sustainability of civil infrastructure against the natural hazards of earthquakes and windstorms. Part of the "Science Nation" series.
While Earth's weather reports center on precipitation, temperature, wind direction, and humidity, space weather forecasts attempt to predict activity that occurs on the sun. Scientists also study how the weather on the sun will affect Earth. At the University of Michigan a team studies solar storms as they form and then barrel off the sun. Sometimes these storms hit the Earth with damaging force. Space weather has the potential to interfere with everything from satellite communications to electrical power. This team is aiming for a five-day forecast capability to give government, private industry, satellite operators, and power grid companies more time to take necessary action to protect critical infrastructure. Part of the "Science Nation."
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.
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.
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 the conditions needed for hurricanes to form as well as the hazards they pose. Part of the Science Video Vocab series.
Jupiter poses many questions about our solar system. It is a powerful planet of gas whose flowing colors and spots are beautiful, but contain violent storms and jet streams. A mini solar system of over sixty moons rotate around Jupiter--a half billion miles from earth. Could one of these moons contain life under its icy crust?
Part of "The Living Oceans" series. Reveals the height and structure of undersea kelp forests inhabited by garibaldi, sea urchins, senorita fish, octopi, moray eels, and sea otters. Shows winter storms detaching kelp from their holdfasts to provide floating nurseries for another generation of fish and other marine animals.
Dr. Chris races against the clock after a policeman’s pet is deliberately poisoned. Also, the clinic takes in a malnourished penguin after severe storms wash it ashore, and a seven month old puppy faces a scary operation after a run in with a car.
Hurricanes are nature's engines of death and destruction, the costliest natural disaster on earth. Explains how and where hurricanes formed; uses live footage to show the forces of wind, weather, and storm surge, and the damage they can do. Compares current information with historical knowledge and notes how forecasting has greatly improved. Explores how meteorologists work to understand and predict these brutal storms.
Scientific evidence may show that human activity, particularly over the past 100 years, has led to a buildup of what are known as "greenhouse gases," the most common of which is carbon dioxide, in the atmosphere. Energy use, particularly the burning of fossil fuels and the large-scale removal of vegetation from the earth's surface, are thought to be largely responsible for greenhouse gas buildup.
Presents the principles of atmospheric dynamics. The Earth's atmosphere is a balance of gases and sunlight that allows for the possibility of life. It has a composition, structure, and life sustaining biological, geological, and chemical cycles in its lower reaches. Also, discusses how these atmospheric elements are being impacted by the unprecedented burning of fossil fuels.
