I explained it in a little more detail.
Windy Map Forecast overlay and background transparency adjustment (only the background map is transparent, excluding the wind animation) Windy Map overlays the existing Openlayers system to adjust the transparency of only the Windy Map's background layer, not the entire window. Open Windy Layer window and set each layer Check mouse location and weather information in Windy Map mode. Adjust wind particle animation color and highlight according to normal/satellite background mapAdditional sources after creating the main map
map = new ol.Map({ … });
Windy_MapInit(‘OL map target DIV name’, map, OL_backgroundTileLayerCount);
Automatically creates three maps of the original openLayers. (If there is a mismatch, check the CSS and correct it)
