Imagine a hive full of bees settling down before bed. <br /><br />I'd been reading and watching on YouTube some of Dr. Jennifer Francis' recent analyses, and was comparing that climate theory to your Alaskan anomalies noted above. <br /><br />I'd come across the Jet path amplification, fragmentation, and stagnation last Fall, but hadn't really connected the Jet to the theory of formation and sustenance of pressure cells. <br /><br />More to learn as always. Now snowing in town again so here we go.<br /><br />Gary<br /><br />NL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-66354520217847033282013-05-03T19:15:49.282-08:002013-05-03T19:15:49.282-08:00Gary, atmospheric Kelvin waves propagate through t...Gary, atmospheric Kelvin waves propagate through the equatorial atmosphere much faster than MJO but impact development of convection. They can produce a more smeared out looking tropical convection pattern than a simple MJO would imply.

Not mine but available elsewhere. Soon we'll be discussing Kelvin Waves and their effect.<br /><br />My next question...does the Jetstream aloft drive the anomalies you described very well above, and very clearly BTW, or do the anomalies alter or otherwise modify the Jet? And if so, at what heights? Who in the end wags the weather tail or has the hammer?<br /><br />Gary<br /><br /><br /><br /><br /><br />The above is beyond good...it's excellent. I wish I had the ability. <br /><br />Thank you.<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.com
