I cant see the colors when I zoom in the map
-
after I upload my kml file into the map, I only can see the colors in a high attitude vision ,when I zoom in the map ,I cant see the colors?
Any one know why? So appreciate about your help.

The images you posted don't appear above; try the alternate control (one of the two available on screenshot), and/or reducing the size of the image files, and/or providing images as a web link (i.e. loading them on any 3rd party web site).

@vsinceac the upper one is after zoom in and without any colors appear

OK, now it is more clear; obviously, weather data layers are removed at big map scales (excepting wind particles and isolines of atmospheric pressure layers), see also this related post. When the map width covers about 50 km on Earth:
- only default layers (wind particles and atmospheric pressure isolines) are displayed on map
- even if UI controls for data layers are still enabled (selection of model, parameter, level, etc.)
- point location control (click on map) displays interpolated values of currently selected data layer
I don't know more. I think Windy staff would be able to explain the reason to do so; it could be related to the max. map scale for which map tiles are pre-computed on server side, or to the poor interpolation results which can be obtained at such a scale from models grids with big cells.

@vsinceac thx bro, so that the only way to get the "COLOR DIFFERENCE" is use small scale

At zoom level 12 and beyond this level, the weather layers are not displayed. At zoom level 12, there is no real point in showing weather layers because of the grid point spacing of the weather model and the smoothing which blurs out any detail. This allows also to show the details of the base map. -
AROME model grid provides values every 1.3 km, thus a 50 km wide map has enough values to interpolate... then Point values on map intepolate very well at such a scale, even for model grids with less resolution. This is why I think the reasons to don't display data layers at big scales is rather related to server performances than protecting base map details (the aim of Windy maps is weather, not base maps). I hope Windy staff could tell more about this...

If it is the server performance that is limiting the weather forecast display beyond zoom level 11, I don't care. You are probably an expert on this subject, I am not.
I was just saying that there is no point in showing the detail of these layers beyond this zoom level for global models. At the early stages, Windy was designed for the ECMWF model and for GFS, not for regional models like AROME which was introduced recently. Then, if Windy shows the detail of the base map up to zoom level 18, which gives a screen map less than 1km, is that not to show the detailed base map? imho there is no point showing at this zoom level a model based on grid points of 9 km spacing.
