| | Weather
|
| | From Learner.org: "New Englanders have a saying: 'If you don't like the weather, just wait a minute.' Weather forecasts may be more stable in other parts of the world, but the basic idea stands. Weather is dynamic, the product of interacting forces we are only beginning to understand." |

| |
| | Severe Weather Info Center
|
| | The information in this World Meteorological Organization (WMO) pilot website is based on advisories issued by Regional Specialized Meteorological Centres (RSMC), and official warnings issued by National Meteorological and Hydrological Services (NMHSs) for their respective countries or regions. |
| |
| | Wave that Shook the World
|
| | On December 26, 2004, at 7:59 a.m. local time, an undersea section of the Earth's crust slipped along a 700-mile-long fault off the coast of Sumatra, setting in motion a train of destructive waves called tsunamis that left well over 250,000 people dead or missing. In "Wave That Shook the World," NOVA traces exactly what happened, and why. |
| |
| | Tsunamis and Earthquakes
|
| | Information on how local tsunamis are generated by earthquakes as well as animations, virtual reality models of tsunamis, and summaries of past research studies. |
| |
| | Tropical Twisters
|
| | From NASA's great site on tropical hurricanes: "Hurricanes are what scientists call "strong Tropical Cyclones". They are formed when large areas of the ocean become heated, and the air pressure over that area drops." |
| |
| | ScienceNow - Hurricanes
|
| | From PBS NOVA, a look at hurricane prediction techniques and recent hurricane ativity. |
| |
| | PBS - Savage Earth
|
| | A great companion site to the PBS series, which provides in-depth lessons and demonstrations on earthquakes, tsunamis, and many other natural weather phenomena. |
| |
| | Where Hurricanes Live
|
| | A great interactive map of the world that provides details on hot spots for hurricane activity. This site requires the Flash plugin! |
| |
| | Hunt for the Supertwister
|
| | PBS NOVA goes supertwister hunting all across the Texas Panhandle. There are lots of great multimedia features on tornadoes! |
| |
| | Animation: Tornadoes
|
| | This animation first shows how vertical wind shear can lead to air spinning around an axis parallel to the ground. An updraft then creates a thunderstorm and moves the spinning air axis to a vertical position, leading to a fully developed mesocyclone with tornado. |
| |
| Storms and Lightning |
| | Lightning
|
| | A great summary review of lightning and its causes. |
| |
| | Severe Storms - Lightning
|
| | From a great ThinkQuest site: "Lightning bolts are triggered when a negatively charged cloud base induces a positive charge in the ground. Negative particles, small streaming sparks known as stepped leaders, begin to flow downward, creating a conductive channel an inch or two wide." |
| |
| | Lightning - ScienceNow
|
| | From PBS NOVA - a look at some new theories on the origins and causes of lightning. |
| |
| Air |
| | The Jet Stream
|
| | From the PBS site: "A step-through presentation that reveals what generates the jet stream and why it flows from west to east." |

| |
| | Air Pollution
|
| | This site explores four major air pollution issues: air quality, acid rain, global warming and ozone depletion.
|
| |
| | What is Wind Chill?
|
| | Brrrrr... For those of you who live where the winter season is in full swing,
it sure is cold outside! But how do we measure just how cold it is? Temperature alone will not tell you how cold it feels if there is a wind blowing! |
| |
| | What is Wind?
|
| | Wind is the movement of air over the surface of the Earth, from areas of high pressure to low pressure. But what causes the changes in pressure? There are a few concepts that we will have to explore to find exactly how this works, but ultimately all the energy on our planet comes from the Sun.Learn more at this great site! |
| |
| | Wind ... the Invisible Force
|
| | A comprehensive wind reference site! |
| |
| Acid Rain and Hydrocarbons |
| | Acid Rain
|
| | Acid rain is rain, snow or fog that is polluted by acid in the atmosphere and damages the environment. Learn more from this great site! |
| |
| | Acid Rain Tutorial
|
| | This tutorial explores the effects of fossil fuel burning on the pH of rainwater, as well as the resulting environmental and industrial consequences. Includes practice exercises. |
| |
| | EPA - Acid Rain
|
| | This site provides information about acid rain's causes and effects, how we measure acid rain, and what is being done to solve the problem.
|
| |
| | ELC - Acid Rain
|
| | If precipitation has a pH of 5.0 or lower, it is considered to be acidic precipitation. How does low pH happen? Find out here.
|
| |
| | Introduction to Acid Rain
|
| | Acid rain is a widespread term used to describe all forms of acid precipitation (rain, snow, hail, fog, etc.). Learn about the causes and effects here! |
| |
| | Hydrocarbons
|
| | Hydrocarbons are a precursor to ground-level ozone, a serious air pollutant in cities across the United States. Learn more about the role hydrocarbons play in creating ozone, the health and environmental effects of ozone, and about hydrocarbon levels where you live. |
| |
| | USGS - Acid Rain
|
| | On-line data and reports on acid rain, atmospheric deposition and precipitation chemistry. |
| |
| | Acid Rain: WSFS
|
| | Acid rain is not pure acid falling from the sky, but rather it is rainfall or atmospheric moisture that has been mixed with elements and gases that have caused the moisture to become more acidic than normal. Learn more at this site! |
| |
| | Acid Rain: Pollution and Politics
|
| | Great multimedia resources on acid rain and related legislation from the CBC. |
