Imo, PaG almost always blows better than TI on NW s.b.s.
In general, our s.b.s don't happen before noon, because they are thermally driven events needing the land to heat up. 1pm - 2pm is most common as the "starting point".
The Coriolis effect seems like it might have a localized influence (who knows, doesn't seem crazy to me). I know it has a huge influence on global wind patterns, but can also affect smaller bodies, like the water in the toilet to spin one way in our part of the world vs. south of the equator. That's an interesting question (I think I will try to find info, out of curiosity
)
If you have access to iKite's FX (or whatever it's called.. I don't pay for it), you can access the wind histories at sites and check out what it did in the past. That can be fairly interesting to look at - if you think the data you are looking at are accurate- and you can get a feel for when s.bs happened in past years at PaG.
