Alternate weather calendar?

I didn't put this question into the ASB section because I'd like to know if it really affects things or not.

Although it's clear that humanity has contributed to global warming and that earthquakes and the times they happen at are inevitable, I'd like to know if a simple historical WI really can affect day-to-day weather events, so that your OTL weather broadcast, assuming it predicts correctly for OTL, might become completely useless if you travel into an ATL. No hurricane on 2005-08-30 in alternate Louisiana? European summer of 2003 with much more rain? Or a climatically similar year in both TLs, but with alternate days to be rainy and sunny?

I ask this question because weather indeed influences history, even if it's not a war battle. Adolf Hitler shortening his putsch anniversary speech on November 9, 1939 and escaping the Munich Beer Hall a mere quarter hour before the one-man-mission-bulit precise time bomb exploded only had to do with concerns of transportation. Weather was bad on that day, so he took the train instead of aircraft to Munich and back and because Hitler wanted to be back in time, he shortened his speech so he could take the relatively slow rail train at an earlier time. No rain on 1939-11-9, and Hitler's assassination would have been perfect. Goddamn it.



PS: Butterfly effect doesn't have to do anything with the butterfly animal flapping its wing differently, but has to do with the guy who discovered the butterfly effect while having to do with butterfly-looking graphs.

Lies! It doesn't have anything to do with Lorenz attractors, actually, but comes from something (not quite) what it means nowadays.

The idea was: you have a weather model, so precise, so amazingly perfect, that it includes everything from the effects of every micrometeorite entering the atmosphere through to North Korean nuke tests. The model is, in fact, perfect -- except that it doesn't model the effects of a single amazonian butterfly flapping its wings once. The effects of this mean that, within a few weeks or months, your perfect model has started making inaccurate predictions, clear skies where there's in fact a hurricane and so forth. The butterfly hasn't caused the hurricane, really; it's just a way of demonstrating chaotic dependency on initial conditions.

AFAIK, this was the original "butterfly effect" example, which has been taken a bit oddly by the popular press. Ironically, AH.COM, with it's "butterflying x away", is actually closest to the original meaning, although by the time you can butterfly x away, w, y, and z will be unrecognizable. The pretty shape of the Lorenz attractor is just a happy coincidence for illustrators.

(So, in answer to your actual :rolleyes: question, I think weather would be different, but earthquakes and the like stay the same.)

You'd have to do something pretty drastic to change the weather . Luckily, climate is so variable that there's plenty of things you cpuld do:

1. Deforestation; would change weather and water patterns, causing butterflies
2. Intense irrigation, draining lakes: same
3. Urban heat islands: cities tend to absorb heat; with a different pattern of urban development (industrialization in a different area, perhaps) you could have lots of butterfly effects later on

That's all I can think of for now...

Nuke tests would do it. So would a war (lots of heat going into the atmosphere) even if you don't believe the strict form of the butterfly effect.
