How Tropical Cyclones, Hurricanes, Typhoons Change the Strength and Waviness of Jet Streams: 1 of 3 // Sep 17, 2020

My main intention in this 3 part video series is to show you how large cyclones (hurricanes, tropical cyclones, typhoons, even medicanes) interact with the jet streams, and can either:

• Add energy to them (amplify them) or
• Take energy from them, depending on their size, extent, rotation direction, and proximity to ridges and/or troughs.
• The modified jet stream (faster or slower; wavier or less wavy; streakier or more uniform)) that results from this interaction then propagates thousands of miles downstream and changes weather there.

Specifically, I show how the strong tropical cyclones that hit the Japan, South Korea region amplified the ridges and troughs of the jet stream, which then propagated downstream over many days and then caused a record breaking weather whiplashing from record warm temperatures in parts of Colorado to freezing temperatures and even snowfall.

It is clear that the jet stream, which guides storms, can have high amplitude ridges and troughs that can break off the jet stream (cutoff lows, for example) generating cyclones, and now it should be clear that cyclones can themselves modify the jet streams by interacting with them.

Yes, the dog wags it’s tail, but clearly the moving tail can also wag the dog!!

‘In the first week of September, sea ice extent took a sharp downward turn, exceeding the pace of decline for any previous year during that period, and placing the 2020 sea ice minimum firmly as second lowest—after 2012—in the 42-year continuous satellite record. Pulses of warm air from north-central Siberia are responsible for the late downward trend. Sea ice decline has slowed in the past few days, and the annual minimum is imminent.’

Perfect example of a tipping point,
in more ways than one:)

Editor / dk:  Paul as a rule eschews public mentions of jubilees on view counts and site visits, but seems more than fair, as we enter our sixth year of five to date, to mention that Paul’s YouTube channel hit five million views a week or so ago, with over twenty-one thousand subscribers now, with certainly well over 600 videos.

And here–at this website–we topped half a million views this summer (now closer to 600k), with 258k discreet visitors, over 26,000 followers, and spread over 189 countries and principalities.  This is upon 372 posts or just slightly below, 1.3 posts per week.

Google indicates Paul, on a back of napkin calculation, as showing up in 4.76M citations or mentions.  Of course, this can vary by accuracy or quality, but some are very good and his mark is clear.  Homeland Security, repeatedly mentions Paul in the same breath as Dr Peter Wadhams, Michael C. Mann, James E. Hansen, Jason Box (regular and current private communication, with key intel, which has THE highest regard for Paul.  He is stated as seen as among the best.  You can bet your life on it).

On his twitter, Paul Beckwith has over 23,000 followers, and is an excellent and steady source of among THE best annectdotal information on climate.  He dependibly posts regular updates.

Lastly, your donations revert to ALL of Paul’s work, and he makes it easy for you, to be able to quickly and conveniently obtain broad scientific climate information, in a way which is easy, cogent, and fast, as well as entertaining.  He  certainly works tirelessly hard.  We thank all of you on behalf of Paul, his team, and supporters.  All ofthis is because of YOU.
