NOTICE and WONDER……

One cannot help but notice and wonder about something like this unusual “sheared mammatus cloud”. But like all clouds it is a phenomenon indicating the incredible things that are going on in our atmosphere.
What secrets do YOU think this cloud is trying to tell us?
The more familiar— but related— type of cloud is the “mammatus cloud”. As shown in photo below it consists of well-defined pouches that hang off of the bases of other types of clouds.

But If you know anything about the formation of more common clouds (such as stratus or cumulus clouds) this is actually the opposite of how those types of clouds form, i.e., through air rising. So there are obviously some unusual things happening when we see any type of mammatus clouds. But from either of the photos above we can visualize that there is some type of downward motion. This is just one example of how careful observation and description can serve as important bases for inquiry.
But all clouds, in general, are just one element of the highly complex phenomena called “Weather” and “Climate”. Although they operate at vastly different spatial and temporal scales weather and climate are comprised of many of the same elements: air temperature, precipitation, humidity, wind direction and speed, and atmospheric pressure. Each of these elements is constantly changing but is also often interacting with the other variables in a highly complex system. One of the major goals of Circle of Illumination Science Education is to help unpack some of this complexity while emphasizing the big ideas in a way that all teachers, regardless of prior knowledge, will be able to comprehend.
