That’s above my pay grade but surfdawg should be able address your question.
I have no real idea if the world wide reduction in particulates and more importantly to others, CO2 emissions, will have any weather pattern effects. Might create more cloud formation, might reduce it? Soot levels should be reduced, and that should help the Arctic ice this summer, maybe? So maybe less melt-off, but maybe more?
I don't think the reduction effects would show up immediately so much, anyway. It's like trying to turn a huge supertanker around. It will take a while and by the time it does, we may be back to near typical emission/particulate levels again. So whatever changes that do happen, would be a blip or hiccup, possibly.
Maybe if this lasted for many months, or well into next year, we might see something, globally. But effects on actual storms or activity levels? Crap shoot IMO.
We're trending towards a possible solid La Nina later this summer, into winter. So, if anything this might either enhance it, or who knows, possibly weaken it. It's all a guess at this point. I doubt anyone knows.
So, this summers EPac Hurricane season may be tough for So Cal, but maybe more landfalls in tropical Mexico. We had quite a drop in Nino3.4 and 1.2 region temps in May. A little bounce back the last week or so, but trend is looking to stay well into La Nina ranges. May be late in summer before So Cal gets a shot at any making it into the window. S. Baja and mainland Mex will be the call more than anything.
So Hemi season looks like it could be decent though. So far, a few decent starter swells. Maybe a classic big one this year (2x-3x overhead), if we're lucky?
