Ep 9. Danger in the Jet Stream
- December 2, 1997
In the 25th season of NOVA, episode 9 titled "Danger in the Jet Stream," the show delves into the complex and ever-changing world of Earth's atmosphere. The episode explores the potentially devastating effects of a phenomenon known as atmospheric blocking, where high-pressure systems in the upper atmosphere stall weather patterns and create deadly heatwaves, droughts, and floods.
Through interviews with leading atmospheric scientists and cutting-edge research, NOVA uncovers the mystery behind the jet stream, a narrow band of fast-moving winds located high in the atmosphere that plays a key role in weather patterns around the globe. The episode examines the various factors that cause it to shift and how this can impact climate conditions on Earth.
The show also explores the use of state-of-the-art technology, such as satellites and high altitude planes, to study these atmospheric patterns and understand the science behind the erratic behavior of the jet stream. Animation and other visuals are used to illustrate the complex dynamics of Earth's atmosphere in an understandable way, making the science behind these phenomena accessible to audiences of all ages.
The episode features real-world examples of the impact of atmospheric blocking on the planet, including the prolonged drought in California and the devastating floods that hit the UK in 2014, as well as the disastrous wildfires that ravaged Australia in 2019-20. The show highlights the importance of understanding and predicting these extreme weather patterns to help mitigate their impact on communities around the world.
The episode concludes with a discussion of the potential impact of climate change on the jet stream and the Earth's atmosphere. NOVA reveals how warming temperatures can lead to increased atmospheric blocking, and explores the dangerous consequences of the rise in extreme weather patterns that such phenomenon can cause.
Overall, NOVA's "Danger in the Jet Stream" is a fascinating and informative exploration of the world of atmospheric science and the complex dynamics that drive weather patterns across the globe. Through a combination of cutting-edge research, stunning visuals, and real-world examples, viewers gain a deeper understanding of the challenges we face in predicting and mitigating the impact of climate change on our environment.
