Gardening: Hazel the hummingbird stll staying warm as snow accumulates in location


Very first, this 7 days I have an update on Hazel the hummingbird who is hanging out at Shelly Horner’s Liberty Lake household. Shelly experiences that as it is gotten colder, Hazel likes to sit on the rim of heat lamp to keep warm.

“She’ll sit there for hours,” Horner mentioned.

I also heard about two more hummingbirds hanging out all-around one more feeder. If you have birds, purchase a heated feeder or wrap LED Christmas lights all-around the feeder to keep it thawed.

Science of snow

Now that we are onto the issue of cold, let us go to snow. Previous Friday proved to be a challenge for quite a few drivers due to the fact the temperatures have been in close proximity to freezing, resulting in slick all the things.

The rationale? The air temperature was in the large 20s, and the air mass coming in had a greater humidity. As a end result of the combination, as the snow crystals were being compacted by cars driving or persons walking, the friction created by the movement made more than enough heat to melt the snow into incredibly thin levels of h2o that resulted in the slippery roads.

Conversely, if you have driven all through a couple of winters in this article, you know that as our temperatures drop into the teens, the snow appears to be to dry out and get considerably less slippery. Driving all around in snow at 15 degrees is completely distinctive from driving in it when it is shut to freezing. Why is this?

Atmospheric problems of temperature, humidity and wind ascertain what forms of snow will kind. Snowflakes in their pure sort are six-sided crystals that arrange by themselves in infinite designs, there are no two snowflakes that are alike.

When snow crystals variety nearer to freezing, the humidity is generally increased and therefore there is much more drinking water available to kind flakes. Warm air retains more dampness than chilly air.

As it receives colder, the air just can’t hold as substantially dampness and the flakes turn out to be scaled-down. These lesser flakes are surrounded by drier air that insulates them from the effects of friction. When they tumble to the floor, the air amongst the flakes even more insulates them and makes it possible for the jagged ice crystals to pack with each other.

As the ice crystals pack alongside one another less than their individual excess weight, there is “micro thawing.” The dampness made below these circumstances refreezes into the areas in between the crystals linking them alongside one another. Since the temperature is properly under freezing, the crystals stick together. As a result, cold snow won’t deliver as substantially slippery drinking water when its compressed.

This is also why snow squeaks beneath foot or a tire when it is truly cold. It is imagined that when chilly snow is stepped on, the bonds involving the ice crystals break and we hear that as a squeak.

For all of you who are new to plowing snow off walks and driveways, keep in mind this. Clean snow is a lot easier to shift than packed snow so really don’t wait to get the clearing performed. If you are plowing a driveway, drive the snow back a to make home for extra more than the winter.
