<![CDATA[windy-plugin-skewt – new features :)]]>Hi all, (@Gkikas-LGPZ @vicb @rittels @stitch @yves @jacobsjo @marekd )

I did a big update of windy-plugin-skewt over the weekend, was wondering if you'd like to check it out. You can now move the purple slider at the surface temperature to get a parcel ascent. Also, it's now possible to open the skewT and spot forecast simultaneously.

Would really appreciate any feedback or bug reports!

Sorry about that, I thought I'd fixed this already. Thanks for reporting the bug. I've just written a fix (v0.9.3).

Let me know if you still see problems.

I found what I think can be a bug.
When I change models, the sounding displayed changes differently depending from which previous model I am changing to.

In my region I have ECMWF - GFS and ICON, in that order from left to right
When I go from any of the first two to ICON, it seems to repeat on of the previous two soundings
When I go from ICON to any of the previous two, it shows a different sounding (the same if I go from ICON to GFS or from ICON to ECMWF)

In total there are three soundings, but it is not clear which one corresponds to which model because of this glitches

I atach two screenshots

I just use the above equation in that calculation, it's just an estimate. Is there a better equation I can use? If not, suggestions on how to approach it? It's been a while since I did this stuff.

John, 500hPa is about 5500m

500 hPa gph rarely observed higher than 6000m

sorry if I'm being slow, but what's the issue?

z = -H * log(P/Po)

so 500 hPa should be around 7000 m, no?

It seems you have something wrong when calculating altitude related to pressure

Easy fix. Either I had originally missed it, or it was added by Windy later, but there is indeed a 250mb datapoint. All I had to do was add it in. You may need to give it a few hours to update, but I've published the change.

Wrong data for 250hPa (FL340).

It seems your plugin doesnt take into account data for 250 hPa (nor interpolate 300~200 hPa data).

windy-plugin-skewt now has a radiosonde feature. I'm still testing it, but please let me know any feedback :)

]]>https://community.windy.com/post/72274https://community.windy.com/post/72274Fri, 05 Mar 2021 21:14:15 GMT<![CDATA[Reply to windy-plugin-skewt – new features :) on Fri, 09 Oct 2020 18:22:08 GMT]]>Amazing feedback, thanks everyone!

@rittels, the skewT is overlapping the spot forecast? I'll look into that. Man I hate cross-browser incompatibility! The error you see isn't anything to worry about, been meaning to find a way to suppress it. It's just the data points in the ascent that I didn't want shown.

Thanks for the info on the temperature discrepancy too @Gkikas-LGPZ and @Yves70, I'll have a look into that for the next version.

Well done. Very cool.

The skewT overlaps the detail a bit, at least on my screen.

There is an error in the console:

Error: attribute d: Expected number, "MNaN,NaNLNaN,NaNL…".

Did you see other discrepancies at other levels between temperatures of the sounding and the map ?

hmmm
what's the temperature at 250 hPa ?
-42 or -44 C ?

Maybe the problem starts from this

Hi John!
You did a great job!
Please, if possible, add the temp. of the purple dot
so we could know the temp. ascent starts.
P.S. I like the old fashioned (traditional) background with the green lines!
It reminds me my first years in the job.

Guess I never really open it that way! I'll look into it, sounds very fixable :)

One remark : if the SkewT disappear and not the picker, if I open it, I can see your plugin

66CA5C82-5E4D-4CAD-AF3C-00152F41C664.jpeg

Now if I click on SkewT (see the picture), I cannot open it, it doesn’t work although it works with the sounding, just above SkewT in the list.

To re-open SkewT, I have to close the picker and chose the location again to open it.

Are you aware about this ?

Hello John, nice new features ! I discovered the new feature with the slider, to get access to LI index but I didn’t now that we could now see the forecast together with the SkewT. This is great. Good work !
