At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of the plants featured in thousands of time-lapse movies Spalding has created over the past five years. The goal is to figure out how to grow crops optimally.

Dr. Randall Hughes is conducting an experiment into how well black mangrove propagules from both local and south Florida trees grow in Saint Joseph Bay. Following a harsh winter, she is able to more thoroughly test the survivorship of black mangroves in northern Gulf marshes. Part of the series In "The Grass, On The Reef."
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.”
Students will explore the climates of the world and learn how weather, landforms, and location affect climate in various places. Part of the Real World Science series.
This segment is all about climate and the role of water and wind. Climate is the statistics of weather over long periods of time. Other topics covered include atmosphere, oceans, and weather. Part of the "Earth Science" 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.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The three friends arrive at a planet surrounded by space debris. Maqui tells them that this debris may come from remains of spaceships or useless artificial satellites. The kids learn the difference between natural satellites and artificial satellites.
El Niño and La Niña are periodic weather patterns resulting from interactions between the ocean and the atmosphere in the Pacific Ocean. Ocean temperatures indicate the presence of El Niño and La Niña, which sometimes lead to extreme weather in many parts of the United States. NOAA climatologists closely track the development of these oscillating systems, which typically last between one to two years. With so much at stake, it’s critical to be able to monitor and forecast when El Niño or La Niña is developing so governments, businesses, and private citizens can prepare.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. Ms. Frizzle transforms the bus into a weather mobile, so Ralphie can become the meteorological superhero of his dreams. This leads the class on the field trip to make a thunderstorm.
Presents the relationships between climates and biomes and climates and people. Also, describes the six major climate types, and shows how weather extremes play a major role in each climate type.
Learn about the difference between weather and climate. Students investigate how glaciers are formed and where they are located. Part of the "Ice Cores: Unlocking Past Climates" series.
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.
How is meteorological information interpreted? A team takes a close up look at the methods, devices, and equipment used to generate, transmit, and process the information for the weather forecast. Part of Invisible Science and Technology Surrounding Series.
Often hard-to-understand concepts of air, gases, air pressure, and layers of the atmosphere are plainly explained in this video. Concepts and terminology: oxygen, nitrogen, layers, weather, jet stream, and northern lights.
Host Trace Dominguez discusses the current trends in the number of hurricanes and their strength. He examines weather data collected since 1880 coupled with new models created by NASA. According to the data and weather models, hurricanes are becoming more intense.
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.
For seven days in the Fall of 2012, Hurricane Sandy pounded the Caribbean and the East Coast of the United States with punishing rain, wind, and waves. What happened in the atmosphere that caused this monstrous storm to form? Summer and winter weather conditions collided with extreme forces to form a super storm. Part of the "Danger Zone" series.
Shows how gravity affects erosion. Documents how scientists study erosion and weathering. Highlights the California landslide problem. Surveys the destruction caused by fast erosion. Explains why deforestation and building houses and other structures contribute to erosion.
Coastlines face numerous threats. Hurricanes, tsunamis, and sea level rise are a few of the dangers that keep coastal communities on edge. With over half of the U.S. population living near the coast, it’s critical to collect and share accurate information on the environment during extreme weather events, and NOAA is leading these efforts. Part of the "Danger Zone" series.
Heat waves, cold waves, droughts and floods are all examples of extreme climatic events. These weather extremes are due in part to climatic change and cause society to ask numerous questions related to their impact on human life. How are these extreme events produced? What effects do they have? And how will a new climatic map on a global level affect humans? Chapter 12 of Air: Climate Change Series.
