How can hail fall when it is above freezing?
Hail can fall and even accumulate on the ground when the air temperatures is well above freezing! Why is this?
Hail is formed in many layers within the sub-freezing tops of thunderstorms. In fact, a hailstone is formed in many layers. Therefore, when the hail speeds toward the ground through the progressively warmer layers of atmosphere, some of the outer layers of the hail may melt, but many layers still remain.
Whatever is left of the hail, which can still be quite a bit (as seen in the photo), then lands and remains on the ground until the rest of the hailstone can melt away on the surface.

First of all, the "hail" in the picture looks like a bunch of golf balls.
ReplyDeleteAnyway, it is neato how hail can fall even tho it is above freezing. I'd like to see a rainbow in the winter. During a splash and dash snow shower.
Have you made a change to the blog? My RSS feed no longer shows the image . I have to click to see the picture. I love this blog. It is everything it should be. A nice picture with a graph or two to explain it. Perfect!
