Wind Shear and Severe Thunderstorms
Wind shear is the ingredient that turns an ordinary thunderstorm into a monster. Study the mechanisms that underlie this transformation. Then evaluate the crucial difference between a severe weather watch versus a warning, and put yourself in the shoes of a forecaster calling the shots.
Squall Line Thunderstorms and Microbursts
Heralded by an ominous-looking formation called a shelf cloud, a squall line is a group of thunderstorms that produces intense, destructive winds. Analyze the anatomy of a squall line, so that you know what to expect next time a shelf cloud approaches. Also investigate microbursts, another dangerous product of thunderstorms.
Supercell Thunderstorms and Hail
Pound for pound, the supercell is the most powerful thunderstorm on Earth. Explore the mechanics of this system, which produces the strongest straight-line winds, the most violent tornadoes, and the largest hail. Close by looking at the formation of a record-breaking hailstone weighing almost two pounds!
The Science of Extreme Weather
Thanks to an ongoing revolution in the science of meteorology, we can now understand how extreme weather conditions arise, produce far more accurate forecasts, and know how to protect ourselves when dangerous conditions develop. The Science of Extreme Weather is your field guide to the worst that Earth's atmosphere can…
Extreme Weather Is Everywhere
Survey the remarkable range of extreme weather around the planet. Then consider: Why does Earth have weather at all? Professor Snodgrass introduces basic features of the atmosphere that naturally lead to severe weather. He concludes by outlining the goals of the course--among them, preparedness.
How Satellites Track Severe Weather
Venture into space to see how different types of weather satellites chart large-scale extreme weather systems in both daylight and darkness. Compare two nearly identical hurricanes--one in 1900, the other in 2008--to highlight the life-saving capability of orbiting weather stations.
El Niño and Cycles of Extreme Weather
Close by investigating one of the most eventful weather triggers of all: the El Nino-Southern Oscillation, which starts as a warming trend in the eastern Pacific and can lead to extreme weather throughout the world. Our detailed understanding of this once-mysterious phenomenon, as well as other extreme weather cycles, shows…
Brain and Self
Episode 20 of Redefining Reality
What makes us distinctly human? Analyze the contributions of genetics, environmental factors, and social interaction to our effective functioning as members of the species. See how CT, MRI, and PET imaging technologies provide windows into brain structure and activity.
Temperature Extremes and Cold-Air Outbreaks
Discover the origin of Earth's great variability in air temperature, and learn how it also explains the seasons. Search for the highest and lowest temperatures on the planet, and the locations with the greatest difference between highs and lows. Along the way, encounter the deadliest weather on Earth.
Low Pressure and Earth’s High Winds
Witness a demonstration of the power of air pressure and the ability of changing pressure to produce clouds. Learn how fluctuations in air pressure play a role in all weather, propelling everything from the ferocious winds of a tornado to the incredible speeds of the jet stream.
Extreme Humidity, Rain, and Fog
Severe weather is driven by water's ability to change phase--with energy being released during the transition from vapor to liquid, and from liquid to ice. Calculate the stupendous amount of energy brewing in a typical thunderstorm, and study cases of extreme humidity, rain, and fog.
How Radar Reveals Storms
In this and the next lecture, study the advanced technology that has revolutionized extreme weather forecasting. Here, look at how radar has vastly improved the prediction of tornadic thunderstorms. You've seen Doppler radar images in forecasts. Now learn how this all-important tracking tool works.
