@Gkikas-LGPZ , @TomSlavkovsky ,

I would also like to add my support for the development and inclusion of a "cross-section" forecast into the Windy platform.

From an aviation forecasting perspective, this add-in would be greatly appreciated and would be supported from those in the aviation industry (both pilots and forecasters).

I don't believe the initial version should require the "icing/turb" display presented in the Ogimet GRAMET product. Just a simple cross section of the currently available model weather data (for instance, wind/temp/dew point/RH and cloud groups - possibly precip) between multi-points would be more than adequate to assist with flight planning and weather route monitoring.

Appreciate all the work and development currently going into this platform.

I'll try that image file again

Hi @johnckealy,

Is it possible for you to change the positioning of the Skewt window? In the current setup, the far bottom section of the Skewt window is covered by the meteogram display (as shown below).


Are you able to shift the Skewt window up so it fits just below the station search window? I am hoping this will uncovered the base of the Skewt plot when also displaying the meteogram plot.

Thanks
Craig

I like the work you are doing with your skewt plugin.

However, I am curious in the methodology you are using to draw the dry-adiab lapse rate (DALR) line to obtain a cloud-base height.

My questioning is directed at how you are getting the DALR at the sfc level starting at a temperature that is a couple of degrees warmer (shifted to the right) than the sfc model temperature?

@vicb ,

I commend you for your work done on the F160 plugin.

Do you have a preference for km/h units in the F160 wind field? Or, could I sway you to use knots as an alternative - widely used unit in marine and aviation professions.

Thanks for you work.

@johnckealy

I was using 0.2.5 and will now switch over 0.2.6.

Thx for your work from a fellow meteorologist!

John,

in addition to my post above, I have just noticed that when running the mouse cursor across the SkewT image, the layer wind/temp/press details are not consistent with the cursor location. It seems like the cursor is offset by about 2cm below the data point it is displaying.

Hi John,

thankyou for your development work on the SkewT plugin.....I have been waiting a while for this addition to the Windy project.

Could I highlight one fault with your plugin and I believe it has to do with the date time used in the SkewT plot not being the same as the Windy background time display.

1/ In the top image (for time 950hpa wind field at 2200local /12Z), the SkewT wind at 950hpa is ~080/45kts.

2/ When I skipped ahead by three time steps (or advanced ahead by 9 hours - see bottom image for 0700local/ 21Z ), I found that the SkewT diagram was now indicating a 950hpa wind of 080/20kt.
a/ The wind field display at the pointer location within the 21Z frame indicates a strong wind 080/45kt. This displayed an inconsistency with the SkewT 950hpa wind 080/20kt for the same time step.

3/ It appears that the wind speed at 950hpa on the SkewT display for the Windy time step 12Z, coincided with the 950hpa wind field image at the pointer location for Windy 21Z display time.

In other words, the SkewT display/time stamp is 9 hours ahead of the Windy display/time stamp.

I looked closer at this because I found inconsistencies with the T/Td trace compared to the displayed cloud fields.
I tested this with other time steps and areas where winds changed noticeably in speed and direction and found the same inconsistency.

Please take a look at your programming. I hope you can see this and are able to rectify this.......I would love to be able to continuing using this plugin.

Regards
Craig

The Windy team can't be too far away; possibly ordering up some coffees before arriving at the office. No update to the models => let's see what the prognosis is!!! mmmm.....WAITING, WAITING.
