Expository Atmospheric Science


Expository Atmospheric Science
















There are many personal essay topic in the atmospheric sciences that can be written about; here are a few.:

Weather Events
Observation Techniques
Technology
Advancements
Debates
The Scientific Method
New Discoveries










Though the one topic I am going to write about is going to be a personal essay. The one that would fit the guidelines of that literary outline is a weather event that happened on May 14th, 2006.








The Sketch for "The May 14th Supercell.":

As the day wore on, the energy of the sky became almost explosive. During the year of 2006, which was a record year of severe thunderstorm warnings for our area, I beheld the first supercell, or tornadic thunderstorm, I had seen in real life. This vigorous system brought with it large hail and tornado in Cabarrus County. The storm was the first tornadic system in a long time to reach my home and I captured many images of that storm. One of the rarest images was that of "the green sky effect" which hail in the core of the supercell bends light filtering in through the roiling clouds. I also saw a mesocyclone, the rotating updraft of the supercell that gives birth to its strong tornadoes. Though no tornado peered through my house, the mesocyclone made its presence known, and I caught an image of it as well. One of the supercell's most astonding features was it's movement. The storm moved so fast it seemed that it was a film in a sped-up movie reel.
One of pleasent side-effects of that storm was the no one was hurt in it of course. Though the supercell did drop a tornado to my east. One of my images from that day were used in a National Weather Service report on that event. It still remains on their website to this day. The supercell was infomative and exiting. That event helped me forward to better meteorological understanding.











The "green sky effect" that occured on 5/14/2006. This is the sky coloration that is usually reported before tornado touchdowns and or hail events. This image is a rare image and is hard to find, if it even exists elsewhere.
