Misty Mountains is an interesting Esri Story map explaining how a prissy mist outcome tin survive created on digital maps past times adjusting the opacity levels of meridian data.
To accomplish this mist outcome lower elevated areas on a Digital Elevation Model are made to a greater extent than opaque together with higher elevated areas are made to a greater extent than transparent. The termination is that fog or mist appears to survive rolling along the valley floors of your map.
The Misty Mountains Story Map goes into to a greater extent than exceptional well-nigh how you lot tin accomplish this outcome past times using a slope opacity score on your meridian information inwards ArcGIS Pro.

You could purpose a like technique to make the appearance of snowfall levels creeping downwardly a mount make every bit wintertime progresses. To create this you lot would simply require to opposite your opacity / transparency gradient, hence that higher elevations are made to a greater extent than opaque together with lower lever are made to a greater extent than transparent on the map. You could together with then increase the transparency of the lower elevated areas on your DEM over fourth dimension to make the appearance of snowfall comprehend creeping lower downwardly mountains over the winter.
