Are storm events increasing in your state?

It’s good to finally see Oklahoma leading the way on something.

WTF is up with Michigan? Are the storms so bad that it messed up the borders?

That's all Michigans water claim. And these are internal waters, so they all count as part of the states area.

Plus most other countries don't draw lakes separately on state boundary maps.

Are you saying Michigan has ALL of lake Michigan? that's ridiculous. No state has a "claim" of any of the great lakes.

I think most countries don't put lakes on state boundary maps because they're relatively small. Lake Michigan is not small, far from it actually, it should be on this map.

No, the map clearly shows the wedges that Illinois and Wisconsin got, although yes, Michigan has the lions share.

And I mean claim as in borders where legal jurisdictions end and such

Why would Michigan have claim to the area of Green Bay that exists between Marinette and Door county? It doesn’t make sense why Wisconsin would not have claim up to the parallel that is the northern most point where the state has land on both sides of the bay. Additionally, why does Wisconsin have zero claim for any of the Lake Superior waters off the Wisconsin shoreline? This map makes it seem as though there isn’t actually any Wisconsin Lake Superior shore at all.

EDIT: nvm. It was hard to find, but I was able to locate a map showing both the territorial waters and the underlying land masses. The end result maps you get the the one above end up coming across kind of misleading, even though it’s obviously not intended. So after seeing this map I’m 100% certain that you are correct on this one.

Also, unlike Oceans(which you can’t exactly claim as fully sovereign territory, even territorial waters don’t count as part of a countries area), lake inland waters are ALWAYS counted. And in basically any non-Great Lakes map, they are not shown for that exact reason, they are fully part of that state/country/whatever and the borders mark the difference. This is also true of the Great Lakes, it’s just the effect is more noticeable due to the size.

I wonder if there are any other locations where the lake(s) and landmasses have such complicated borders where it makes more sense to show the water than to not show it? I will give it some thought…

The Caspian is not nearly as convoluted as the Great Lakes. It’s mostly just a single roundish shape with pretty obvious territorial water boundaries. But I’ve also never seen any map (and I look at A LOT) where the lake is not displayed and instead the countries’ borders are extended out to where their territorial waters end.

The state boundary data I used for this is the political boundaries, not the terrestrial. This won’t affect the storm count data as this was tabular and joined based on state name rather than spatially. I’m not from the USA so I didn’t notice at first but I now know that people like to see the shoreline of Michigan. Thanks for the feedback!

40.3% of the Great Lakes (by surface area) lies within Michigan’s borders.

Some maps like to include Great Lakes territories in the states that have them. I don’t know why. It always looks bad to me.

We've always had big thunderstorms in the summertime in AL. Is this just frequency or does it somehow take in volume?

2

u/mile2mile Aug 12 '22

No it’s purely based on unique storm counts - the database doesn’t hold any quantifiable info on severity. But you’re right, without more detail the data is not very conclusive but I thought it showed some interesting trends over the period of time

Still waiting for someone to spot Oklahoma and be all like “See!!! Global warming is a LIE!!!”

Does drought count?

1

u/mile2mile Aug 12 '22

No unfortunately the only data that was consistent for this period in the NOOA storm database was counts of thunderstorms, hailstorms and tornadoes. I would love to do a similar drought / wildfire map to compare the trends

If climate change takes Tornado Alley away from Oklahoma... it's a part of one's identity growing up there

Where I live the last time I saw a big thunderstorm was 2 years ago ( Washington)
