— Fresh snow can play a big role in keeping the Miami Valley colder in the winter, according to Storm Center 7 Meteorologist Kirstie Zontini.
“With no snow on the ground, sunshine warms the ground, and in turn the air,” Zontini said. “This can help us get into the 30s or 40s even during the winter when the ground is snow-free.”
But when snow is on the ground, the story changes, Zontini says.
“Snow has a high albedo, which means it can very effectively reflect incoming solar radiation it receives from the sun during the day. Snow pack will reflect about 50-percent to 90-percent of the incoming solar rays back out to space and the other part is used to melt the snow,” Zontini said.
Because the snow is reflecting the solar radiation, the radiation doesn’t have the ability to warm the ground and air, meaning colder temperatures during the day and at night.
