Some of the Cc is of the variety undulatus. Miscellaneous Cirrus in the lower part of the image.

 

Picture taken on 25.6.2023 at 01:27 local time.

A sun pillar is formed when horizontally floating hexagonal ice crystals (in this case within the Cirrus) reflect light. Kinda like the reflection of the setting sun over wavy water, but in this case upside down.

I volunteer. I modded a similar subreddit back in the day before leaving Reddit, and am fully fluent in latin cloud nomenclature.

The notations can be confusing, especially around noon and midnight. Is midnight am or pm when it's equally distant to both the previous and the next noon? Why does 12am not follow 11am???

Where I live we use 12hr time in casual spoken language but pretty much always specify the time of day as well, like eight in the evening or twelve at midnight. But for anything written or even remotely formal, 24h time is used for obvious reasons.

Sure, but the vast majority of people live in low lying areas and even then it doesn't shift that drastically. You need to climb a mountain to see the difference when it comes to applications of daily life.

Although now that I think about it. The same criticism applies to pretty much every definition of temperature that is based on the behaviour of matter. This also applies to Kelvin. Temperature is a property of matter and every type of matter behaves differently.

The thing to remember is that air is a great insulator. Air at 100°C isn't nearly as bad as say water or metal at the same temperature against the skin. In fact, the air that comes in contact with the comparatively cold human skin will cool down rapidly, forming a layer of cooler air around you and lessening the sensation of heat further.

100°C is nice. And what's a steaming session? Throwing water onto the rocks for steam every now and then is just standard operating procedure.

Water is everywhere.

Cooking, weather, etc. You are also water.

The headline is clickbait since you don't even need to get past the paywall to see that "The website does not appear to be linked to Hamas". That domain is registered under Wix.Com Ltd., an Israeli software company. There is no hacking involved here, just an Israeli site masquerading as a Hamas site gloating with attrocities.

I think that this is part of a propaganda effort by Israel to capitalize on the October 7th attacks by maximising the emotional response from it. It's all in English, so clearly directed at western audiences. It's also quite on the nose with the caricaturistic portrayal of evil terrorist baby killers who do not understand PR.

If an actual Hamas site was hacked by Israelis, I'd expect the hackers to flaunt their victory by posting something the islamists clearly wouldn't (like idk pictures of ~~bacon,~~ a woman's ankles or maybe some dudes kissing).

As for an actual Hamas site, I'd expect a lot less displays of gore caused by Hamas and a lot more displays of gore caused by the IDF.

Sort of a continuation to that other post I just made here. Here's a picture I took last year of a spectacular sunset caused by Cirrus spissatus.. These clouds were quite high at over 8 km above the ground.

The secret recepie of a great sunrise or sunset is that the sky is covered in clouds that are high, but also thick enough to produce strong contrasts between the highlights and the shadows. Farther away in the direction of the Sun the sky has to be clear enough to allow sunlight to illuminate the bottom of the cloud. Here the cloud in qustion is Altocumulus stratiformis. It's quite a common cloud, and thus also the most common culprit of spectacular vistas such as these. Cirrus spissatus is also a great candidate, although that one is a bit rarer and doesn't usually form expansive sheets such as here.

Meidän toiminta?

Se portin sulkeminen ja lapun jättäminen luukulle. Menee filosofiseks, mutta omission ja aktin raja on hiuksen hieno. Auttamatta jättäminen on omissio, portin sulkeminen ja lapun luukulle jättäminen taas on akti. Tässä tilanteessa se ja sama kummalla mennään.

Tässä on ajateltava itsekkäästi.

Itsekkäästihän tässä ollaan ajateltu kaiken aikaa. Sisäpoliittinen kuohunta on Suomen valtion omien intressien vastaista.

Meidän ei tule pelata samaa peliä.

Ollaan kuule pelattu samaa peliä jo siitä lähtien kun aiheesta alettiin puhumaan mediassa. Ainoa tapa jolla me oltais vältetty pelin pelaaminen, olis se että oltais otettu kaikki pakolaiset sisään ilman mitään mutinaa, koska ei muutama tuhatkaan pakolaista oo oikeesti tunnu missään pakolaiskriisin jälkeen. Tosin aivan varmasti Persut ja muut rasistit olis tästä silti vetäneet herneen nenään, jolloinka vaikutusyritys sais silloinkin jotakin aikaan.

Epäiletkö etteikö niin voisi tapahtua? Kun nyt vielä erikseen otit ihan itse esillle sen mitä Puolan rajoilla tapahtui?

Väännetään nyt sit rautalangasta: Lähes kaikki jotka sinne Puolan rajalle meni, meni itse omatoimisesti ajatellen että heitä odottaa parempi elämä Puolassa. Pakkokeinot tuli käyttöön vasta kun pakolaiset koitti pettyneinä kääntyä takaisin. Tilanne on siis nyt erilainen, koska Venäjä joutuu käyttämään pakkokeinoja jo tässä vaiheessa ihmisten saamiseen sinne rajalle. Ihmismassojen saaminen jonnekkin on paljon helpompaa jos ne menee sinne itse. Kovin veikkaan että Venäjällä olevat pakolaiset ovat kuulleet Puolan tapahtumista eivätkä halua samaan tilanteeseen.

Fluctus is a cloud formation that requires quite specific circumstances to occur. The physical phenomenon itself (Kelvin-Helmholtz instability) is quite common, occuring at the border of two layers of fluids moving in different directions and/or speeds. The most common instance would be the waves you see on water.

But to be visible in a cloud like this, there not only needs to be a cloud at that same place, but it has to also occur perpendicularly to the observer so you can see it clearly from the side like this. Because of these three factors rarely happening all at once, as well as the short lifespan of the formation (the waves usually crash within minutes), it is widely considered a rarity.

Safe to say, I was very stoked when I saw one lining up for this shot.
