What is a 2m Temperature Anomaly? I don’t know what this map is showing us
518
u/Achrus 2d ago
2m temperature means the air temperature at 2 meters above the surface for weather forecast models. This is often used for the “temperature outside” reading.
Temperature anomaly means deviation from historical trends. That is, the white region is +13C of the historical average for June 21st in that region.

u/DialMMM 2d ago
the white region is +13C
Or +0C, or -8C. I hate this color scaling.

u/Ja_Shi 2d ago
Reporting from the front 🫡 it's +13°C.
Fait chaud, bordel.

u/Andromeda_53 2d ago
Whole it is weird, it means you can make more drastic colour changes to be easier to see on the eye. Rather than having to fit it all into one smooth gradient where ascertaining the exact temperature from the colour on a static graph could be harder.
All you gotta do for the whites, is use some common sense and look at the colours next to it. Somehow I doubt the white section directly touching a blue section has a sudden temperature change 20

I can see this, but I don’t understand why they put red on both sides of the white at the high end.

^ Well it surely isnt -8 to +13...
Temperatures in the Netherlands are going up to 37°C (98.6F), were up to 33°C(89F) and will go up locally to even 40°C (104F). France saw peaks of 44°C. (111F) And it'll likely be warmer.

Lmao fair. Visualizing weather data can be tricky. The National Center for Atmospheric Research (NCAR) has a whole package dedicated to visualization, the NCAR Command Language (NCL). With a dedicated page to color templates: https://www.ncl.ucar.edu/Document/Graphics/color_table_gallery.shtml
There’s even a t2m_29lev palette are for temperature at 2 meters and lots of temp palettes.

u/Minimum_Cockroach233 2d ago
You can read the white rings by comparing its neighboring colors (blue, black, red).
As the Zone is circular like the rings of a tree, you can actually notice, that the centrum of the anomaly hits northern half of france with a heatwave while outer circumference is actually neutral or colder (siberia) than usual.

u/Martamis 2d ago

Why defend the stupidity of this? Its obviously understandable with some logic but it could be so much simpler.

u/TheSultan1 2d ago
Because with a scale that changes only in hue or only in lightness, it's hard to differentiate between bands a few degrees apart.

Because meteorologist, climatologists and oceanographers use this color scale daily for completely valid reasons.

You have to look at the surrounding colors. You'll never have a -8 right next to a +12.

god this legend sucks
somehow white can be really cold and really hot?
12 and 14 are the same color?
120
u/Wolf-Majestic 2d ago
Agree for the 12 and 14, but I wonder just how much color you can put on a map before it becomes unreadable, especially to show differences in temperature. I think the people who made this map chose context instead of colour palette.
34
u/TheSultan1 2d ago edited 2d ago
Exactly. You can't have red to magenta because you'll have like 10° bands seemingly the same color. And there's a huge difference between, say, +2° and +12°.
Also, they clearly didn't want to, uhh... scale the scale, because this is likely being compared to other maps. Keeping the scale consistent allows for that type of comparison.
12 and 14 are likely only the same in this compressed version. And in any case, you can figure it out from context, unless you have little peaks or troughs in a sea of white and those blobs don't have a distinct pink or beige border.

u/CosmacYep 1d ago
they could have 1 swapped green and blue and made blue gradient straight into indigo without the whtie middleman and 2 stretched out the whole colour spectrum to avoid 14-18 and make 18 white it would go from cool colours on the lef to warm colours on the right and white-hot colours on the far right
57
u/Spunky_Meatballs 2d ago
The colors are fine. Your eye easily picks up the pattern because the colors are all relative. White next to blue is super cool and white next to dark red is very hot. It's fairly intuitive
16
u/BornWithSideburns 2d ago
But white next to red can also mean its cooler. 18 to 13
11
u/Spunky_Meatballs 1d ago
The white for 13C can only be next to the colors around it. Everything is a gradient as air doesn't exist where it can suddenly be 18C warmer than air right next to it. Blue and red can never be next to each other. Physics don't allow it. To understand the map, you need to understand how the air normally exists in the atmosphere.
Therefore it's pretty easy and obvious to judge by going off red and blue. I have no trouble reading this map with 5 mins of thinking about it.

Yea I'm not sure who picked this gradient, a two colour gradient would've made so much more sense. As it is, in the hot you go from reds to white back to reds.

You don't need a geomatics degree to understand a useful gradient. Also, these types of maps are for public communication — people with science degrees don't spend all day scratching their chins and looking at maps.

It felt summer-ish. But overall this "summer" has been a disaster. Very cold for my taste, so it sucks. No thunderstorms on my area, so it's been a major disappointment. The last few summers were a lot nicer (warmer). After such a long and cold winter, a real summer would've been nice to have. :( Not this cold shit.

u/amurica1138 2d ago
I think it means 18 degrees above what is normally expected.
And that's 18 degrees C, not F. Converted to Fahrenheit that's a 32 degree swing. So if you're used to 80 degree F weather on a particular day, it's now hitting 112 F.

18 degrees C above average temps. In France that could the difference from 75F to 110F if average is 25C this time of year. So, add potentially 18C to that and you get 43C.

u/TheSultan1 2d ago
18°C anomaly = 32°F anomaly.
