windy-plugin-skewt – new features :)

[johnckealy]

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!

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 !

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

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 ?

[johnckealy]

@Yves70, awesome, thanks for that. Guess I never really open it that way! I'll look into it, sounds very fixable :)

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.

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

Maybe the problem starts from this

@Gkikas-LGPZ
Did you see other discrepancies at other levels between temperatures of the sounding and the map ?

[Gkikas LGPZ]

@Yves70
No.

Correlation seems to be good at other levels :

@johnckealy

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…".

[johnckealy]

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.

Hi All,

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

@johnckealy
Wrong data for 250hPa (FL340).

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

Same problem found here https://community.windy.com/topic/7963/upper-air-temperatures

Thanks for the feeback @Gkikas-LGPZ. 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.
