The Big 5 Natural Causes of Climate Change: part 2 Jet Streams and Extreme Weather
Welcome everyone.
This is part 2 of the big 5 natural causes of climate change: focusing on jet streams and extreme weather. Jet streams are high-altitude, fast-moving, narrow bands of winds that separate cold arctic air from warm tropical air. Jet streams are key to understanding climate change because they both create weather and steer weather around the globe. Unlike global warming, jet streams undeniably cause both extreme heat waves and extreme cold snaps as well as directly causing droughts and floods
Jet streams cause extreme weather when their waviness increases and causes weather patterns to linger over a region longer than normal. Examinations of the jet stream's cycle of waviness was first published by MIT’s Carl-Gustav Rossby in the 1940s.
To honor his profound contributions to understanding atmospheric circulation and its effects on climate, wavy jet streams, as well as other wavy circulation patterns, are called Rossby waves
Rossby insisted that the jet stream's wavy patterns were essential for the planet to achieve greater temperature equilibrium more efficiently as each wave's ridge transports more warm tropical air poleward and each trough drives more cold arctic air equator-ward.
