In 2019, a December storm dropped around five inches
of snow over northeast China near Baicheng.
If conditions on the ground are right, a snow pattern can reveal
a storm's path with remarkable detail.
Landsat 8 captured this image of the area,
revealing a distinct division between snow cover and clear ground.
This stark divide is rare when trees and mountains are present,
but not uncommon on flat, harvested croplands.
A similar pattern appeared in the midwestern U.S.
after a major storm system moved through on the
day after Christmas in 2018.
The storm left behind a miles-wide trail of white connecting
New Mexico and Nebraska.
In this Sentinel-2A view, the defined edge breaks
around the hilly, forested features near the Cimarron River.
The lack of snow could be attributed to those features,
but also to slightly warmer temperatures near the river.
