    • Useful/interesting colour scales

      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

    • Trajectory based on markers on Sat layer

      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

    • RE: Useful/interesting colour scales

      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)

    • RE: Trajectory based on markers on Sat layer

      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.

    • RE: The island where it never rains...

      @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
      defefdb7-ad51-4337-9a49-73631c6e0da4-image.png
      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

    • a Radar overlapping satellite layer

      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

    • forecast value, when in the hour? preceding or following?

      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?

    • Change rainClouds gradient

      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?

      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

    • Radiosonde Plugin - No past Ascent

      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
