hey buddy, nice to see you here. To answer your question - no clue. I have been wanting to educate myself about this a bit more but to really dig in takes time. I think that weather is something we are wired to pay attention to and therefore anecdotal evidence / personal experience creates a lot of noise around trying to understand climate data (for the lay person, that is). I suspect we have always had 'crazy weather' from time to time. Climate change, writ large, is buried in the climate data. One of the numbers to pay attention to is CO2 concentration in ppm. I can't see how that can continue to rocket up without something very bad happening.

Thanks for the link. My question - are these systems coming to us more frequently or severely, or is it just a function of increased awareness about forthcoming weather systems?

To whit - I've always been intrigued about weather (and how earth systems work on a macro level) but its only been the past couple of years that I've been aware that "high pressure systems" (normally clear and sunny) rotate clockwise, and that "low pressure systems" rotate counter-clockwise.

They therefore how they impact our weather. (at the front of the systems - colder, fresher air from the north; warmer, humid, moisture-filled (in the centre and east of North America, anyway, thanks to the Gulf of Mexico. The West gets all gummed up because of the mountains, and Atlantic Canada because of Atlantic ocean effects).

The reverse, of course, happens as the arse-end of the systems pass.

Anywho, I now can understand this better due to much better weather satellite imagery. But it DOES seem that more systems are moving through, and moving through more rapidly. Or is it just me?

(sadly, the Weather Network, which used to be more detailed, academic, and informative, had become focused on the "emotional weather" the past few years. Sad, that. They used to have a loyal viewership looking for accurate weather forecasts that made sense.) (I, for one, now get my weather from the morning Fox news Boston local broadcast - they're weatherperson is intelligent, informative, and sexy)
