Well, sea-ice spread increased from Feb through end of March. If I didn't have a job, I would confirm with a time-series of north-south, mid-latitudinally averaged wind patterns to view mixing between mid-latiude and polar cells. But I do have a full-time job (thank heavens), thus I "expect" the spread to increase with stronger jet and less north-south mixing between midlatitude and polar cells. The instability builds (Feb/March) and eventually releases, causing advected air from south to melt sea-ice and cool air from north to impact midlatitudes (April). I referenced this before in theStag's discussion (see 28038060 and 28040633). Note, I expected trough to be centered over Minnesota, and it ended up centered over Michigan, so I was wrong. accuweather.com For my own good, did anything happen with solar wind that allowed the Feb/March set-up occur? In other words, would a certain easing of solar wind allow the jet to build strong enough to not allow energy conversions of synoptic waves + influcence of Rossby waves? Or is it all just low-frequency distributions (Rossby waves)?
