Hi, first post here from a devoted weather hobbyist who I know some of the contributors on here will have 'bumped' into across the Internet ether - congratulations on a tremendous thread and the intellectual dissection of the various teleconnections, exam questions and current challenges in understanding the mechanics of our atmosphere. Particular well done for making the connections to get the AAM data available. Really is something that we ought to protect and cherish.
Hope to contribute over time - when time allows. Meanwhile from today, we see out winter friend or foe cranking up a gear across the column...

Probably my favourite strat obs site in terms of ease of interpretation, also pleasing to see much more new material coming online this season courtesy of Dr Lopez and Zac Lawrence. Will certaintly be another winter of watch and learn as we have the subtle nuances of the QBO switch in play as the season progresses.
Keep up the great work all !
