What "unknown precipitation" means in a METAR

I'm visiting my sister, who lives near KMPV. Since I live in the southeastern US and fly a PA32, no way was I going to try to fly up here in the forecast wx, and a good thing too. I purposely live someplace where we don't get lots of ice and snow (just tornadoes, heavy convective activity, and Roy Moore ads).

I was looking at the METAR this morning and this is what I saw:

KMPV 281213Z AUTO 17011KT 5SM UP BR OVC026 M03/M04 A3018 RMK AO2 UPE1155B09SNB1155E09 P0001 T10281044

The code UP was new to me, so I did a little google fu and found this explanation, which cleared it right up.

tl;dr: ASOS reports use an automated sensor for determining precip type and sometimes it just shrugs and says "WTF?" Then you get UP in your METAR.

George Mason University from the perspective of a native Northern Virginian

Hi everyone! I hope all of you are doing well and staying safe.

With the new trend on A2C of sharing information about universities near home, I've thought that it's a fantastic idea, and I wanted to make a post for George Mason University for anyone coming here. I don't think many students on A2C apply here, but I wanted to make a post just in case.

GMU's Vibe

  • Overall, GMU has very nice vibes. Everytime I've visited GMU for a swimming meet or an event sponsored by the university, the people there have been very welcoming, friendly, and awesome.
  • One important thing to note about GMU, however, is that most of the student body is either Northern Virginian and/or nontraditional students (e.g. adults who graduated with a bachelor degree who now want a graduate degree, students who want to do undergrad again, etc.) meaning that a good amount of the student body either lives off-campus or lives home with their family. Thus, there isn't necessarily a ton going on on the campus itself.
  • However, there is still a considerable amount of students living on-campus, so if you're interested in doing things on-campus, there are definitely ways to get involved! Even though GMU gets the reputation of a commuter school, they have some really neat campus events, such as their annual April international week. They also have over 350 student-run organizations.
  • GMU is in Fairfax, which is a really odd mix of a urban and suburban area. If you're someone who likes urban areas, but prefers it to have a touch of suburban emotion, you'd probably like Fairfax a ton as it's a good mix of the two.

Weather

  • NoVA weather is very strange in that it fluctuates all the time, especially in the winter. Once every five years or so, we tend to get a giant blizzard with tons and tons of snow. However, most years, we strangely don't, and the temperatures can get really cold sometimes, near -10 degrees Celsius at its worst.
  • On the flip side, however, it can get really hot in the late spring to early fall periods. It's pretty normal for the temperature to reach 37+ degrees Celsius in June, July, and August.
  • On the super bright side, though, there isn't too much precipitation meaning that there's a good chance that you'll get a chance to bicycle, run, or walk outside in your free time. The autumn season in NoVA is especially very nice. The tree colors look great, the temperature is just right, an

Correlation between mean annual precipitation and climatic stochasticity

Hello All,

I am an ecologist that is very interested in understanding how climatic variability drives animal adaptations. For example, locusts (a subset of grasshoppers) are highly migratory likely in order to persist in arid environments with little rain to support significant grass (food) growth. So, they migrate in hopes to find an area that had rain and grass growth.

This has me thinking a lot about the casual correlation I have noticed in my work. Drier environments usually are more stochastic climatically as compared to wetter environments (think Australia vs. the tropical rainforests of Indonesia). I am not a meteorologist whatsoever but is this an actual trend? Could I make the statement that decreasing mean annual precipitation is correlated with increasing climatic stochasticity?

Thanks!

[Question] How much land do I need?

Context: My wife and I are starting to seriously save up and look at property. Our plan is to continue working our full time jobs, at least for now, but start transitioning over to a more homestead lifestyle. We'd like to be 100% self sufficient in terms of basic fruits and vegetables. We live in zone 9b so officially our growing season is all year. However, summer heat and precipitation mean we realistically have about 9 months for anything that can't stand the heat. We'd like to have some animals, most likely just chickens or ducks for eggs. We cook at least 90% of our own meals instead of going out or using prepared meal options. We're also trying to cut processed foods as much as humanly possible.

So, what's the minimum amount of space we need to grow vegetables to support 2 (eventually 3) people and have a bit left over for chickens?

My back of the napkin estimates have it at at least 1 acre of usable land if you include a small orchard area, a kitchen garden, and some permaculture perennial beds.

[TOMT][SONG][PRE-2005?] Family ignorant towards proper power/water saving techniques during dinner

(reposting from a month ago because I didn't get any responses)

I saw someone else's post about an environmental song, and it reminded me of something I sang for the "third grade show" in elementary school. Our theme that year (2005/2006) was the environment/anti-polution/anti-waste.

This song was about a family that's wasteful with water and power.

It's less singing and more speaking/rhythm/rap. During the whole performance, anyone who wasn't part of the family kept a rhythm by rubbing their hands together three times and then clapping once on the fourth beat.

I'm pretty sure it was a family of four: mother, father, daughter, son. Maybe they had a dog (played by another kid)?

I remember the first part exactly, because I auditioned for the role of the mother (but didn't get it):

MOM: Soup's on, come and get it! Dinner everyone! The table is set and the food's about done!

DAD: Where's Danny? (Denny? Could even be Sammy?)

SISTER: Up in the shower!

DAD: He's been in that shower, for almost an hour!

The song ended with everyone screaming because of a power surge, and they lost power. (In fact, the last words of the song might have been "power surge," and I could've sworn that was the title.)

I actually came across some songs my grade sang from a previous year, that I think might be from the same company? (Because it would make sense for my music teacher to have bought multiple books from the same source...)

The Weather Rap - A Kids-Eye View Of The Weather By Roger Emerson

The song I linked was the one I actually remembered out of all of them, Precipitation Means It's Gonna Be Wet.

After some digging, I found an old catalog for music teachers, with Assignment: Earth By Roger Emerson.

Join the β€œE Team” as they apply β€œKid Power” to the problems we all face in cleaning up the environment. This contemporary all-school revue features eight original unison/2-part songs in a variety of styles from Broadway and pop to rock and rap. Songs include: It’s Our World, Turn It Off! Turn It Off, Don’t Throw It All Away, The β€œO” Zone, and more. 30 minutes.

I don't recognize any of the titles, but it could be Turn It Off! Turn It Off, but of course when I search for it, all that comes up is The Book of Mormon.

The audio from the cassette/CD would be amazing, but I'd be content with just the lyrics!

YSK that β€˜X percent chance of rain’ doesn’t actually mean the chance of precipitation.

It is worked out by confidence x percentage of area getting hit by rain. So, if the forecaster was 100 percent there would be rain, but only for 20 percent of the area, then the chance of rain would only be 20 percent.

If you don’t get it look at this: https://www.forbes.com/sites/marshallshepherd/2015/11/27/do-you-or-your-meteorologist-understand-what-40-chance-of-rain-means/#6707cd3225d5

Quick update from Hank - FTD Cycle

********** Not a financial advisor. Not financial advice**********

https://preview.redd.it/8yfbwi2zasv61.png?width=1170&format=png&auto=webp&s=1c8705410d909110c224cc0a9a7e2ed710f13859

Apety apety apes. What's the difference between GME and my wife? GME doesn't fuck the mailman. Though my wife is a legal midget, GME is still wayyyyyyyyyyy more shorted than she is. Alright, enough about me. As always, remember to see my previous posts about the FTD cycle theory or you will be more confused than I am when my wife ISNT cheating on me. Also, I hope you apes like my new avatar. Like everything else I do, my goal was to make it as abusrd and strange as possible.

So today's post is just gonna be a quick update on what's happening with GME and the FTD Cycle and obviously a meme drop. My plan is to give big updates when something major happens or when I do new research and then smaller updates like these whenever I see necessary of when I get bored.

Today

Overall, today was a pretty good day. We were up slightly on lower volume but not as low as it has been in recent weeks. We almost hit $200 in the post-market yesterday and I would've liked to see us hit that again today but you cant have everything. Let's take positive days when they're given to us. Here's a day view of the FTD cycle theory.

https://preview.redd.it/n8f0titsasv61.png?width=1992&format=png&auto=webp&s=d798d43f4e56dd1d6c9a8cc3f5210dca94148443

Just want to reemphasize a point that someone made yesterday. When I used a log scale and noted that the FTD Cycle period was increasing linearly, I failed to realize that a linear increase on a logarithmic scale is exponential on a regular scale. This makes complete and total sense because less than a year ago when this started we were trading below $30 and never got near $50 until early January, so the idea that the pattern is exponential seems to make sense. This means that as time goes on, the price should increase rapidly until it's too late. Again, I don't believe that anyone will see it coming when we finally moon, so don't try to predict that. Yes, it's possible to guess when we will see increases, but I don't think it's possible nor beneficial to try to predict when we moon. Finally, I just want to reemphasize the idea that the point of this theory is that it gets more expensive for shorts to continue this game every cycle and that pain seems to be increasing exponentially.
