Four Interesting Lessons About Winter Weather
How windchill is calculated:
The windchill was -20F last night at my house. The following video explains how windchill is calculated. The video comes from Presh Talwalkar.
The psychology of extreme weather:
Television news reporters like to use the word "extreme" whenever we have a lot of rain or snow in a short amount of time. Is the weather really "extreme" or is that just our impression of it? The following Minute Earth video takes on the topic of how extreme weather affects our thinking about weather patterns in general. I found the video to be interesting from a psychology perspective. The video is embedded below.
How snowflakes are created:
The following episode of Bytesize Science embedded below explains how snowflakes are created.
Thundersnow is a video from UNC-TV that explains how thunder sometimes, though rarely, coincides with snowstorms. PBS Learning Media has a set of corresponding lesson materials that you can use with this video.
