Pressure Maps

Last week in class we discussed Pressure Maps. First we divided a map into sections as a class. Here is what it looked like.

As a homework assignment we were asked to color code another map based on the pressures that were provided. In the following picture you can see how my map turned out.

The Perfect Storm

The Perfect Storm occurred in Gloucester, Massachusetts in October of 1991. It is the true story of the tragic death of six sword-fishermen and the sinking of their boat the Andrea Gail. They got stuck in the middle of the collision of Hurricane Grace and a cold front coming from the northwest. Their attempt to escape the storm was unsuccessful and they ultimately drowned. According to the National Climatic Data Center, The Perfect Storm resulted in damages costing hundreds of millions of dollars. Here are some satellite pictures of the storm.

For more information about the Perfect Storm refer to the following links.

The Great Miami Hurricane of 1926

In light of Hurricane Sandy I have decided to chronicle another notable hurricane in history-The Great Miami Hurricane of 1926.

In 1926 there were not as many advances in technology that allowed the public to be notified of an approaching storm as quickly as we can be notified today and for that reason "hurricane warnings were not issued until midnight on September 18th, which gave the booming population of South Florida little notice of the impending disaster." When the hurricane reached South Florida it was a Category 4 hurricane and it traveled directly over Miami Beach and downtown Miami. According to the National Oceanic and Atmospheric Administration "this cyclone produced the highest sustained winds ever recorded in the United States at the time, and the barometric pressure fell to 27.61 inches as the eye passed over Miami." All of the buildings located in the downtown district of Miami sustained damages or were completely destroyed.

Before this hurricane, South Florida had a booming economy; but because of all of the destruction it caused, this storm marked the end of their prospering economy. In today's dollars, this hurricane would have been a $90 billion disaster. "With a highly transient population across southeastern Florida during the 1920s, the death toll is uncertain since more than 800 people were missing in the aftermath of the cyclone. A Red Cross report lists 373 deaths and 6,381 injuries as a result of the hurricane."

Here are a couple of maps of the path that The Great Miami Hurricane of 1926 followed.

Sunrise and Sunset in Macon, Georgia

Today I recorded the location of the Sun in the sky at different times of the day in Macon, Georgia. Below you will find a table that shows the Time, Temperature, Humidity, Dew Point, and the Weather Condition at a specific time as well as a depiction of where the Sun was positioned in the sky at various times throughout the day. The color of the squares correspond to the time on the table that is the same color.

How to Make a Barometer

Recently I had to make a barometer. To do so I needed a glass jar, a balloon, tape, scissors, and a straw. I cut the balloon in half and placed it on top of the glass jar. I taped the straw to the middle of the balloon and then cut the end of the straw off at an angle.

When the pressure on the outside of the jar is more than the pressure on the inside it will push down on the balloon and cause the straw to go up. 

If the pressure on the inside of the jar is more than the pressure on the outside then the pressure on the inside will cause the balloon to bulge and the straw will point downwards. 

Here are a few videos on how to make different versions of barometers.

Comparison of Cities Along the Same Longitude

The five cities I chose to compare were Charlotte, North Carolina, Miami, Florida, Manta, Ecuador, Chitre, Panama, and Colon, Cuba. 

Charlotte is located at 35 degrees, 13 minutes, and 37.51 seconds North and 80 degrees, 50 minutes, and 35.26 seconds West. The sun rose at 7:35 am and will set at 6:40 pm. The high temperature for today was 68 degrees Fahrenheit and the low was 44 degrees Fahrenheit. Here is a picture of Charlotte.

Wind Rose Plots

Wind Rose Plots show the percentage of time the wind blows in a certain direction. Below you will find several Wind Rose Plots I created by using archived data from the year of 1992. The Wind Rose Plots depict the direction the wind was blowing in Macon, Georgia on various days throughout 1992. Here is a picture of the location the wind speeds were collected.
