New sounding with radiosonde measurements

idefix37

I was knowing this convention that the barbs of the arrow-feather, showing wind direction and speed, point to the low pressure area on a wind map.
Concerning a sounding diagram it seems you are right.
Here are 2 examples in North hemisphere shown at 500hPa level:

In South hemisphere, in Windy Sounding forecast, the barbs are shown pointing outwards the low pressure area, which is inconsistent. The wind direction is correct (clockwise in low pressure areas) but barbs should point to the opposite:

BTW speaking of wind barbs, a lot of people don't know why we use that word. Early weather maps showed the direction and speed of the wind by arrows with a tip and feather fletching. Weather map in 1888:

Nowadays the barbs are only on one side of the arrow and the tip is missing, replaced by a circle in surface analysis maps. Barbs point towards the low pressure zone as said in the previous posts.

@marekd

Can you provide a solution to the wind barb/arrow direction within the sounding tool to follow the convention that the barb/arrows point towards the area of lowest pressure?

For the current Sounding Tool....when the latitude changes to -ve (Sth Hem), the barb/arrows need to be drawn on the opposite side to what is currently being displayed.

W'ly wind
in the Nth Hem: point to the left (up - in sounding tool)
in the Sth Hem: point to the right (down - in sounding tool)

You can follow the discussion for added comments.

Thx

@airmalik Hi, thank you for the report. We will fix it in the next version.

Love the new zoomable sounding. Each time I close it down, I have to re-enable the paragliding spots toggle if I want to look at a new site. Don’t think I had to do this with the previous sounding and I don’t see an advantage to it. Is this a small bug?

@Mark-Mortimer Hello, it is correct since the new sounding is technically a POI overlay, so when you select it, the other overlay gets unselected.

Great job with the new sounding! Really love it. Only on my mobile device (Android) the time bar, were you can adjust day and daytime, disappears now. This makes it quite hard to check the development over the day. I hope you can make the time bar topmost or so :)

@fcrgb Hi, thanks for the feedback. I discussed this with our development team, and we will consider adding the timeline back into the future release.

Bonjour,
D'autres paramètres du radio sondage devraient être affichés.

I like this tool very much.
I've realized that today forecast sounding don't offer near radiosounding like before.
And another thing that have changed is that when you are in a radiosounding, the option to see historical radiosounding have dissapeared.

This makes keeping track of progress during the day challenging. I'm crossing my fingers that the clock will reach the summit.
