Yet another bug report

Cannot modify the colour scale via the windy.com website by pasting it in the text area. Does not let you write anything in there...

However, i can modify it if i change each line in the coloured box above the text area

looking forwards to the fix ;-)

Also if temperature of sea air and dewpoint could be different i would appreciate that

There are automated weather fronts at Meteomatics

I want to add my voice to johnsondanl

I would like to have radar overlayed on satellite

Weather radar and Satellite are my favourite "models"!

but to be precise I would say ecmwf default given that it historically verifies better, and then check the others models if i care a little more

Hello,
Windy's radar and satellite layers are very flexible and easy to navigate>

I would like to see a combined product.
Can there be a third layer where radar is overlapped to the sat picture?

Something like this

This might be a very simple question but when does the forecast apply?
Is it the preceding hour or the following hour of the valid time?

For example if the forecast is at Anglesey airport in Wales, UK is
at 08:00Z Temp = 12C and Wind = 24KT

Does that apply to the following hour 08:00-->08:59Z,
or to the preceding hour 07:01-->08:00?
Would a perfect forecast vs observation be when the 07:50Z observation shows 12C 24KT or when the 08:50Z shows it?

Hello,
Is there a way to change the rainClouds gradient to get rid of the low amounts of rain?

say i wanted only to show rain above 4mm/3hr, can i do so?

@corsita
WIndy is taking the data directly from the thai met serivce.
https://www.tmd.go.th/en/ and https://weather.tmd.go.th/

They have a number of rain radar stations. Navigating through i think there are two that cover the island of Ko Mak

The further away Suvarnbhumi which could have some mountains in the way.
https://weather.tmd.go.th/svp240.php

and the closer one is Sattahip https://weather.tmd.go.th/satLoop.php

which appears to be in a direct line of sight, thus i would not expect any radar shadow to affect the island.

I am not sure why Ko Mak appears to be without rain. However, i don't think you can trust the rain radar for the area in general. This is the edge of the range of the rain radar and the quality of the data deteriorates the further out you go. Mainly is due to problems with detecting a good signal bouncing back and in particular with the radar beam being very high above the ground.
The beam is at a shallow angle upwards (probably 2° or 3°), but in 200km range that is 7-10km; Any rain below that is not going to be detected

@anthony10 I used to work at UK Met Office. The resolution of the global model is 10km

I would love to see UKMO data on Windy as well

they are back. Thank you

What was the issue?

Hi @korina. SOrry i don't understand the question
Radiosondes ascents from met stations are still happening and should be freely available. The should be available to be shown in the plugin

Hello,
I like using the radiosonde plugin and the fact that i can compare model to actual ascents it's great.
Unfortunately it looks like the actual ascents are not available anymore.
The last ascent i can see for the UK in Herstmonceux for example is from 2022-06-30 23:00Z

Something changes in july and the data location as changed?

thanks for looking into this
dodohjk

same issue here.
Thank you @rittels for the great plugin

this is a wind scale useful for highlighting areas of good wind power for wind turbines.
it highlights in green the area of moderate wind production (5-10m/s) and yellow when it reaches typical rated wind capacity (10-15m/s) becoming red around max power (15-20m/s).
Violet and grey will highlight wind speeds that are too strong and might cause wind turbines to shut down (>20-25m/s)

Hello,
Some of you will know that you can set the colour scales of various units to suit your preferences.
https://community.windy.com/topic/10336/customize-the-color-scales-of-windy-layers

This is great but changing the colour scale is a rather slow process imo (eg a good gradient temp europe would have a low range in the middle east).

I would like to start a thread of useful and interesting colour scales including the code to copy.
Please post a screenshot of the colour scale, an example map and the associated code ready to copy. See my example below

Exactly! thank you @idefix37 for making it more clear

To quote the old saying "Model useful but wrong", thus extrapolating the sat and radar in the 1 to 6hr range can give me more accurate prediction especially for showers.

@korina
the problem with Distance and planning is that it covers the time validity of the satellite layer.

here is an example
imagine i want to track the movement of this shower over rotterdam

when i open distance and planning i have the satellite time bar covered by the tool.

ideally i would be able to put waypoints at various location and times, calcualte the average speed and direction and nowcast where it is going for the next few hours

@korina
is route planner same as Distance and planning when right clicking?

Hello
I have a suggestion for the trajectory/tracking plugin or for a similar plugin to expand windy's capabilities.

I would like to be able to track cloud from the satellite or weather radar layer. Unfortunately the plugin wants model data to work.
Is it possible to select the model for trajectory calculation while still being on the satellite layer? (one can go back and forward between model layer but it is a more complicated)

Can a user defined trajectory be made? ideally the user would select multiple points along a line at different time steps and then the plugin would calculate a linear progression forward
EG Point A at 0km at 12Z, Point B at 50KM East at 13Z, Point C at 100km East at 14Z, then the plug in will calculate other points at 75km eastwards every hour

Hopefully it makes sense what i wrote.
cheers
Riccardo

@gkikas-lgpz
The scale in the bottom right is an approximate scale that uses the standard height levels used in aviation like
950hPa / 2 000ft / 600m
850hPa / 5 000ft / 1500m
700hPa / 10 000ft / 3000m
300 hPa / 30 000 ft / 9000m
etcc
These are approximately equal and used for easy conversion between different unit. However they are not exact.
In fact heights of pressure levels changes with different weather conditions. eg cooler temps have pressure levels closer to the ground as the air is denser.
More info can be found here https://en.wikipedia.org/wiki/International_Standard_Atmosphere

Anyway the scale on the left is the model calculated height taking account of the meteo conditions (i think at least).
I am pretty sure that the scale on the windy map on the right is the correct values at the "model pressure height" which is an approximate height in m or feet.

@gkikas-lgpz said in Sounding Plugin - for paraglider pilots:

..... at lower levels

point "B" marks the temp. at 600 hPa (13800 ft, FL140)
but the diagram shows 12000 ft (1800ft off).
