The Science of Extreme Weather is an engaging and informative show from The Great Courses Signature Collection, starring renowned climatologist Eric Snodgrass. The show explores the fascinating science behind some of the world's most extreme weather phenomena, from hurricanes and tornadoes to droughts and heat waves. Over the course of the show, Snodgrass takes viewers on an in-depth journey through the mechanisms that drive extreme weather events, starting with the basics of atmospheric science and meteorology. He explains the role of the sun's energy in driving weather patterns, the physics of atmospheric pressure, and the way in which air currents and storms form and move across the planet. From there, the show dives into specific extreme weather phenomena, incorporating beautiful visuals, fascinating stories, and plenty of data and scientific analysis along the way. For example, viewers will learn about the anatomy of a hurricane, exploring the ways in which massive storms like Hurricane Katrina form, intensify, and wreak havoc on human communities. Snodgrass uses real-life examples to illustrate the science behind hurricanes, discussing the impact of factors like sea-surface temperature and atmospheric pressure on storm behavior. The show also covers other types of extreme weather, such as tornadoes and lightning storms. Snodgrass explains how warm, moist air rising from the ground can create the conditions needed for a twister to form, while also discussing some of the key features that characterize these deadly storms. Meanwhile, the lightning storm segment delves into the electrical physics that underlie these incredible natural phenomena, as well as explaining the role that temperature, moisture, and other factors play in creating electrical charges in the atmosphere. Alongside these more dramatic weather phenomena, the show also covers less visible forms of extreme weather, such as droughts and heat waves. Snodgrass discusses the differences between these weather patterns and others, discussing the way in which extreme heat and dryness can have profound effects on human lives and ecosystems alike. He also explores the connections between climate change and extreme weather, discussing the ways in which rising temperatures and changing atmospheric conditions can amplify weather patterns and make them more intense or frequent. Throughout the show, Snodgrass emphasizes the importance of understanding extreme weather from a scientific perspective. By explaining the complex mechanisms that drive these phenomena, he helps viewers to appreciate the beauty and power of nature while also appreciating the tremendous risks that extreme weather events can pose. He also highlights the value of scientific research and data analysis in predicting and mitigating extreme weather. Overall, The Science of Extreme Weather is an excellent educational show that combines stunning visuals, clear explanations, and fascinating real-life stories to create an immersive exploration of some of the world's most incredible natural phenomena. If you're interested in learning more about atmospheric science, meteorology, and the way in which physics and weather patterns interact, this show is definitely worth checking out.

From the American dust bowl of the 1930s to the relentless expansion of the Sahara in Africa, drought represents severe weather that can stretch out for years. Explore what€™s going on in the atmosphere to create extreme drought, which is associated with heat waves and dust storms.

19. Flash Floods and Deadly Moving Water

November 1, 2016

Consider the deadly power of moving water. Explore scenarios for extreme flooding in flood-prone regions of the U.S. and consider past cases of extreme coastal floods, river floods, and flash floods. Study the meteorology behind these events, and hear flood safety tips.

18. Blizzards and Winter Cyclones

November 1, 2016

Look back at historical blizzards that paralyzed major U.S. cities. Then probe the official definition of a blizzard, the cold-weather cyclone systems that create them, and the revolution in forecasting blizzards since 1993. Focus on the role of the jet stream, and dispel a common misunderstanding of the polar vortex.

17. Epic Snowfall and the Lake Effect

November 1, 2016

The region downwind from the Great Lakes is famous for its lake effect snowstorms, which can total more than 200 inches of snow per year for some locations. Examine the factors behind this phenomenon as well as the mortal danger posed by blizzards, as shown by the tragic Children€™s Blizzard of 1888.

16. Ice Storms: Freezing Rain Takes Over

November 1, 2016

Begin the first of three lectures on winter weather by pinning down the cause of ice storms, which are beautiful but also dangerous and destructive. Professor Snodgrass demonstrates how supercooled water is the source of the freezing rain behind these perilous storms.

15. Mountain Windstorms and Avalanches

November 1, 2016

Study the impact of mountains on weather by investigating the Chinook winds, which can race down the east face of the Rocky Mountains with tornadic force.
