The jet stream is a fast flowing narrow air stream that flows from west to east around the globe. Jet streams are caused by temperature and pressure differences. They play an important role in influencing weather systems by moving air masses and storms.
Origin of the term and application
Japanese meteorologist Wasaburo Oishi discovered the jet stream in the 1920s but it was not until 1939 that a German meteorologist Heinrich Seilkopf coined the name “jet stream” for this air stream.
The discovery and understanding of jet streams have aided meteorological forecasting, particularly weather forecasts. However, scientists are increasingly interested in how to harness the wind energy of the jet streams to provide energy for human use. Those scientists investigating the use of jet streams claim that only 1% of the wind energy of jet streams would be sufficient to provide all of the world’s energy needs. Other scientists caution that harnessing the wind energy of jet streams would have a severely negative impact on the climate.
FAQ
What is a jet stream and what role does it play in weather systems?
A jet stream is a fast flowing narrow air stream that flows from west to east around the globe, influencing weather systems by moving air masses and storms.
Who discovered the jet stream and when was it named?
The jet stream was discovered by Japanese meteorologist Wasaburo Oishi in the 1920s, and the term ‘jet stream’ was coined by German meteorologist Heinrich Seilkopf in 1939.
How has the understanding of jet streams benefited meteorology?
The understanding of jet streams has improved weather forecasting by allowing meteorologists to predict weather patterns and storm movements more accurately.
Is there potential to harness jet stream wind energy for human use?
Yes, some scientists believe that only about 1% of the wind energy from jet streams could meet the world’s energy needs, though there are concerns about the environmental impact of such energy extraction.
What are the concerns associated with harnessing jet stream energy?
Scientists caution that harnessing the wind energy of jet streams could have severely negative effects on the climate.
