Description
Weather may be a frequent conversation topic, but making it a focus of curiosity and amazement-that's a rare triumph. This program succeeds through a combination of eye-popping motion graphics, irreverent humor, and cutting-edge scientific expertise. Drawn from the United Kingdom's top level of meteorology and physics researchers, four on-screen commentators address a wide range of provocative yet rarely considered questions-from "Why is weather so...

Destabilization in the Middle East and concerns over global warming are heating up the national dialogue on how America intends to power itself into the future. In segment one of this NewsHour program, Michael Marvin, of the Council for Sustainable Energy; Dan Reicher, of the World Resources Institute; Myron Ebell, of the Competitive Enterprise Group; and Herbert Inhaber, author of Why Energy Conservation Fails, consider the big picture. Then, segment...

To predict weather and understand climates, researchers use physics, environmental science, mathematics, and information technology to interpret huge amounts of oceanic, atmospheric, and terrestrial data. Filmed with the assistance of Australia's Bureau of Meteorology, this program introduces the allied sciences of meteorology and climatology. After explaining how the sun, wind, and clouds interact to create weather, the video explains how scientific...

Most scientist have resisted the idea of cloud seeding, which is done by releasing fine particles of silver iodide into the air to get clouds to produce more rainches However, this video clip takes a look at new research that offers hard evidence that cloud seeding can produce good amounts of extra rainfall when needed.

Where on Earth does the temperature drop to -128 degrees Fahrenheit? What is a wind farm? And how does rain look from an ant's perspective? Combining remarkable time-lapse and slow-motion photography with news footage and diagrams, this program provides a thorough overview of the causes and effects of the Earth's weather. Sections one through three present temperature, wind, and precipitation, while sections four through seven focus on weather measurement,...

Violent weather touches thousands of lives, homes and businesses around the world each year. Billions of dollars are spent on cleanup and reconstruction. Climatologists and meteorologists at the Meteorological Alpine Project (MAP) are using specialized computer technology to discover how hot winds in the African desert develop into a damaging hail storm in the Swiss Alps.

Throughout history, floods have killed more people and caused more widespread destruction than any kind of event other than war. A catastrophic flood in China in 1931 is believed to have resulted in four million deaths, making it the world's worst ever natural disaster. This program examines the causes of floods, the havoc they wreak and what, if anything, can be done to protect against them.

Tornadoes and flash floods can happen at the same time. But the safety instructions for what you’re supposed to do during each one often contradict one another. Now meteorologists and social scientists are working together to identify when these two severe weather events occur together and how best to communicate that information to the public.

Description
How do you turn this thing off? Well, you can’t. This is Earth, and the power button is always switched on. The energy is always flowing. But where is the button? Where does this energy come from? You’re about to find out. Topics include: Energy and Heat, Solar Energy, Geothermal Energy, and Convection.

Atmospheric phenomena directly influence the formation of different landscapes of our planet. In this program we’ll discuss the weather forecast, the atmosphere, the troposphere, meteorological observation stations, and more. Topics include: Rain, Hail, Lightning, Cloud Formation, Thunder Storms, Hurricanes, and Tornadoes.
17) Lightning
Language
English
Description
The inside of a storm cloud is home to millions of ice particles rubbing against each other and generating static electricity, until the charge is so intense that it strikes down, or upward, in the form of lightning.
18) Drought Culprit
Language
English
Description
For many years scientists have turned to the Southern and Pacific Oceans to try to predict when the drought breaking rains will come to Australia, but now they have a different explanation. This video clip investigates whether the Indian Ocean might be the culprit behind the worst drought on record.

Extreme weather events can cause widespread damage resulting in billions of dollars of losses. Recent events, such as blizzards, hurricanes, and droughts have been exceptionally devastating as a result of several environmental factors. The convergence of several weather systems and the right atmospheric conditions sometimes result in the “perfect storm.” This issue examines the factors behind catastrophic weather. It explains El Niño and La Niña,...

Description
Tropical cyclones, also called hurricanes and typhoons, cause catastrophic damage when they strike land. When a cyclone’s fury unleashes on population centers, death, injury, and wholesale destruction follow. This program explores the life cycle of cyclones: how atmospheric conditions, ocean temperatures, and the Earth’s rotation combine to create them and how, driven by winds, they eventually weaken after moving over land.
