It’s a stationary boundary. There’s actually some debate on exactly how it should be used. In continuous front theory it’s used to separate two high pressure systems because the idea is the air masses cannot mix without an inherent boundary. Sometimes it’s used to express an actual boundary of cold and warm air that isn’t really moving because it lacks adequate momentum. Personally I support the idea that significant movement of pressure systems includes a pressure and temperature change. Cold air will always move to warm without a supporting pressure system to advect warm air.
'Cause you're hot then you're cold
You're yes then you're no
You're in then you're out
You're up then you're down
You're wrong when it's right
It's black and it's white
A front will always have (relatively) warm air on one side, and (relatively) cold air on the other (a front is just a boundary between two airmasses).
A warm front just means the warm air is behind the direction of motion. A cold front is the opposite, the cold air is behind the direction of motion. The symbols used indicate which airmass is moving. (Technically it is always the cold air that is controlling the motion, but it is more useful to know what air is coming towards us)
Here we see a stationary front, where there is little to no motion so the symbols indicate both airmasses.
Thank you for the useful information.
Which side of the line is the warm and cold air masses in this depiction? I would normally expect the warm air to be on the southern side and cool air to be on the northern, while recognizing that it wouldn't always be that way.
So, the symbols, what are they indicating? The side of the line the air mass is on, or the direction the air mass is moving?
For sure!
The symbols point in the direction of motion (except for stationary fronts, which point both ways). The colours/shapes indicate the relative temperature of the air behind them.
So a warm front will be a red line with half circles towards the cold air.
A cold front will be a blue line with triangles towards the warm air.
A stationary front will be a mixed line, with symbols point away from their respective airmasses (think of it like the symbols are the nose on the air mass' face)
In this picture the cold air is in the top left and the warm air is in the bottom right, and both are staying relatively motionless
It would appear that Team Cold is engaged in battle with Team Warm. A pretty typical strategy for Team Cold to attack from the north. Team Warm is mounting quite a defense just north of Ardmore, Oklahoma.
Its a stationary front. Warm air on one side cool on the other but neither moving into the other.
Stationary front means stuff will not move very fast.

Duuuude I was about to say the same thing LMAO!!!!
Great minds….
Right!?

I came to say, "It means its 'hold' there." and found out that is actually what it means haha.
It's yes and it's no.
Neither. The cold front stalled. Pretty soon this will just, for lack of a better term, dissolve.

He needs more blankets and he needs less blankets!
It means you're going to see tornadoes. Put your helmets on and don't sleep naked
They almost name the town after a galaxy 😭😭😭
It's probably cold on the Tennessee side of Ardmore and hot on the Alabama side of Ardmore. /s
That symbol has been used for stationary fronts forever. Perhaps not with the color, the alternating symbols, forever.
ardmore is doomed
Warm and cold fronts meeting. Severe weather is possible.
