ShareEarth's Energy - The Weather's Changin'
A new radar technology known as "Cloudsat" is designed for scientists to observe the interior of clouds. Most cloud radar technology of the past was designed showing only the uppermost layers of clouds. Scientists determined that it might be possible to gain more information on cloud structure and movement if they were able to see the entire cloud.
Balloonists have noticed for years that the air currents may not always be constant despite a steady weather pattern. If you watch these balloons move after they rise off the ground, some interesting patterns are seen. The higher the balloon moves, the more you notice it may change direction of travel. It appears, though we cannot see them, that there are several layers of the atmosphere where air currents occur.
Depending on where you live, you may have observed weather patterns
occurring based on the topography of the land. As air rises over mountains,
it cools. Often during the cooling process, clouds form. Thunderclouds
are often associated with mountains. Another weather pattern common
to Utah is the "lake effect." When clouds cross the Great
Salt Lake, the amount of moisture in the clouds increases. When this
heavier air reaches the mountains, it drops a greater amount of precipitation
than is seen in areas farther from the lake.
Try It!
Now consider that you are going to design the location for a new town.
Your goal is to provide an area with enough stable weather patterns that
plants grow easily in the town. In addition, you have control over every
factor that nature typically provides. You, therefore, can have lakes,
oceans, mountains, rivers, or other abiotic factors to assist your weather
pattern. Create a diorama of this ideal town. Make sure you indicate how
the land features assist you in "controlling" the weather. Share
your diorama with friends, classmates, a parent or teacher.
