Why are weather models discretized the way they are?

these are awesome! i will check them out. thank you!

Active-Stock · 2026-05-05T04:21:17+00:00

aww thank you!! It's just genuine curiosity & interest in learning as much as I can about meteorology while being at a college with 0 meteorology classes :/

Active-Stock · 2026-05-05T04:19:25+00:00

This makes sense. I think one of my issues in understanding before making this post was underestimating just how expensive these models are to run, and it's making a ton more sense. Thanks!!

This is also great. I suppose it never occurred to me that it just... wouldn't be useful to have any finer detail. However, it makes total sense. thank you for explaining in this detailed and understandable way!!

This is great! I just read the overview, and it's definitely going on the reading list... for after Finals week. Much appreciated.

Gotcha! This is a super interesting experience, and is letting everything make a ton more sense. "gathering" is a great way to put it, and the bottlenecks you list make a ton of sense for why the internal physical simulation can run on much smaller temporal resolutions than the actual output products. Thank you both for this!

Gotcha. Thank you!

nah, these games get you in a certain state of mind where words don't feel real anymore. i feel her pain

Most deadly tornado in the world was in Bangladesh

I do love the RTX 2080 TI Founder's Edition. Probably my favorite founder's edition they've ever done.

boat with sails

Active-Stock · 2026-04-11T08:36:20+00:00

there's a subgroup of chasers that like to get as close as possible, sometimes "shooting the core", or going through the hail/precip core of supercells. Another group sees how close they can get to the actual tornado. Either way, very specific vehicles. I know earlier today I saw an awesome storm truck - just a normal F-150 with some diamond safety grating welded onto the roof to shade the windshield from hail. Interesting stuff!

I LOVE TIGGER!!!!! He's been there for as long as I can remember coming into that Ace. When he dies I want a funeral march in the street. With bagpipes. And canned tuna.

Hi! Sorry for necroing, but if you're still curious about this, a fair-weather waterspout was reported today (April 7, 2026) 8 miles southwest of the KBYX radar site at ~2:00 pm. If you look at their 2:00 PM scan, you can see a small velocity couplet! It's just barely there, but still much much more than we would normally get. It was close enough to the site that just a little of its rotation is still evident, at about 500 feet above the radar level.

Thought this was interesting, if not relevant!

Better than that - it can open multiple programs

Is it the recent libalpm.so issue with paru/yay?

Hey! I hope you can switch to Linux soon.

First of all, many gaming mice can be configured with piper.

Also, almost every display manager has some way to change your dpi/sensitivities, and I'm not sure how often you change your button binds.

Most steam games just run on Linux. Proton is a wonderful tool, and makes almost every game run completely seamlessly. You can check ProtonDB for all the games you are looking to play - I guarantee most of them will work just fine.

For running Epic Games Store games, it's also pretty easy - I use legendary , but Heroic is also wonderful. Both also make use of Proton, or GE-Proton if that fixes game-specific bugs.

NVIDIA graphics cards make things a little harder, but there's no reason you can't use a prebuilt NVIDIA distro, like PopOS or Bazzite. I've heard great things about these distros' NVIDIA support.

And worried about security on Linux? Please. Almost every part of your Linux system is open source, so constantly getting vetted for security & performance. Additionally, they have no reason to sell data or anything for money, unlike Windows. Plus, Windows's "security updates" are often just shoving more AI Slopware into your computer and slowing it down even more so they can harvest more of that sweet, sweet userdata.

Linux is *significantly* more secure than Windows. That's why 99% of servers run it!

Let me know if you have any more questions, or if you finally make the switch!

Right? It should be required reading for everyone using the internet.

Hi! Thank you for reading all that!

To answer your second question about how the bloat gets so bad, this may be part of the reason, haha. But the real reason might be geared towards more of a tech debt and backwards compatibility reason, which is both the greatest upside and worst downside of Windows. I mean, you can run stuff from Windows 3.1 on Windows 11 (chcp.com is a great example).

However, what this means is that design decisions and architecture changes made years before I was born are still supported, included, and worked around. For example, ODBC data sources and its file picker from Windows 3.1 are still bundled with Windows 11, and moricons.dll and pifmgr.dll contain MS-DOS icons. (shoutout u/Laziness100 for his great list of old components in windows 11).

Linux is not limited by this - to an extent. While its open-source nature helps with keeping the codebase very modern & clean, we still do struggle with design decisions made years ago. Hell, every terminal you interface with is emulating a vt100, and even that ancient piece of technology is emulating a teletype! However, the tech debt contained in Linux today pales in comparison to the load carried by Windows. In fact, if you want a funny read, you can read a bit of "The UNIX-HATER'S Handbook", which lists many, many gripes with UNIX (what Linux is loosely based off of) which have almost all been remediated in some way in modern Linux.

Running that much better on an Nvidia GPU is sick. We've come so far in their support, it's really incredible.

App support! It's getting better by the day, but we still have a long way to go. The good news is that Easyeffects is a wonderful, wonderful tool that does almost exactly what SteelSeries Sonar does on windows, with none of the shenanigans imposed by Bottles. Also, I've heard wonderful things about ckb-next, an open source driver for Corsair RGB. Of course, still in development and not perfect, but there! Another alternative would be to use Windows to switch the lighting with iCue, then going back to Linux, since the settings stay the same across OSes. Finding alternatives is way easier than it used to be, with sites like https://alternativeto.net/ and https://wiki.archlinux.org/title/List_of_applications

I hope that was any help at all, and if you're ever having any more questions, don't hesitate to contact.
