Unit 2 Assignment Part 1:
Altitude (km) vs. Temperature (°C) in the Atmosphere
Tropopause Stratopause Mesopause
Hint: The y-axis should range from 0-100km in 5km increments. The x-axis should be a temperature scale from -100 to 20°C in 10-degree increments.
Use your course readings to answer the following questions:
Question 1: What is the basic composition of clean, dry air (containing no dust, smoke, water vapor or other particulates)?
Troposphere
Stratosphere/Ozone layer
Thermosphere
Mesosphere
-
The basic composition of clean dry air with no dust smoke water vapor or other particulates is 78% nitrogen 21% oxygen and 1% argon.
Question 2: Why is the ozone layer important for life on Earth?
-
The reason the ozone is so important for life on earth is because it acts like a shield by protecting us form the sun’s UV light. Without it we are more at risk of skin cancer and other harmful and deadly diseases. Plants and other organisms would die, and our ecosystem would be in jeopardy.
Question 3: Explain the increase in temperature in the stratosphere and the decrease in temperature in the mesosphere.
-
The temperature in the stratosphere increases because this is where the ozone is. Since the ozone protects us from the heat of the sun, the stratosphere’s temperature is normally warmer. Therefore, the mesosphere’s temperature would be lower and cooler because there is no ozone layer meaning there are less gas molecules to trap the heat of the sun. Question 4: What is the relationship between altitude and air pressure?
-
The higher the altitude the lower the air pressure and vice versa.
Unit 2 Assignment Part 2:
Use the assigned video clips to answer the following questions:
Question 1: What are the conditions necessary for a hurricane to form?
-
In order for a hurricane to form the ocean needs to be warm and still with a temperature of over 79 degrees Fahrenheit for a prolonged period so that a body of warm air can form above the surface. That combined with low altitude winds blowing from different directions cause these huge clouds in the atmosphere that develop into hurricanes.
Question 2: What are the stages of the life cycle of a hurricane?
-
The three life stages of a hurricane are its source, the mature stage, and the dissipation stage. They all occur in a continuous process and not as separate stages and can repeat as the storm’s strength rises and falls.
Question 3: What is the relationship between storm intensity and air pressure?
-
A storm’s intensity is based on their air pressure. The lower the air pressure the more intense and stronger a storm is. Question 4: Choose one of the storms from the Hurricane History video clip. With web research and from what you learned in the video, answer the following:
4a. Describe the path of the hurricane.
-
The hurricane I decided to
research was the Labor Day
Hurricane of 1935. The path of
this hurricane began off the east
coast of the Bahamas and made
its way westward towards
Florida. It was predicted to go
through the Florida Straight and
then into the Gulf of Mexico
and then later predicted to be
heading towards Cuba.
However, in the matter of 24
hours it went from a category 1
storm to a category 5 storm and
was headed straight for the keys
making land fall between Miami
and Key West. It then went
northward traveling parallel to
the west coast of Florida until it went inland towards Georgia, and the Carolinas. It then went back towards the Atlantic Ocean just off the coast of Virgina where it continued to travel northeast until it dissipated up near Greenland.
4b. Describe the maximum windspeeds and minimum air pressure associated with the storm.
-
This hurricane at some points had over 200 miles per hour winds with sustained winds of 185mph. It also had the lowest air pressure ever recorded at the time for a hurricane with 892 mb.
4c. What Saffir Simpson category was the hurricane when it made landfall?
-
This hurricane was the first category 5 hurricane to make landfall in the U.S. in recorded history.
4d. What impacts were experienced on land as a result of your chosen hurricane?
-
There were 409 fatalities due to the storm and 259 of those were World War 1 veterans helping build the overseas railway. And it caused $100 millions dollars in damages with a
destruction path of over 40 miles in the keys.

Unit 2 Assignment Part 3:
Analysis Questions:
The Koppen Climate Classification System is the most widely used system for climate classification across the world. There are five major climate types recognized:
A – Tropical Moist Climates
B – Dry Climates
C – Moist Mid-Latitude Climates with Mild Winters
D – Moist Mid-Latitude Climates with Cold Winters
E – Polar Climates
Visit the PhysicalGeography.net website
to read the characteristics for each of the climate types: Question 1: Classify each of the three locations based on the Koppen Climate descriptions and describe the characteristics you identified to make your choices.
-
Fort Lauderdale, FL falls under the tropical wet climate (Af) according to the Koppen Climate Classification System. This is because precipitation occurs all year long, and monthly temperature variations are less than 3 degrees Celsius. -
New York City, NY falls under a humid subtropical climate (Cfa) according to the Koppen Climate Classification System. This is because they have rainfall all year round with hot humid summers, but they also have cool wet winters. With temperatures reaching below 50 degrees Fahrenheit from October through April. -
San Juan, PR falls under the tropical wet climate (Af) according to the Koppen Climate Classification System. This is because they have warm weather and precipitation all year around. With an average day time high temperature of 32 degrees Celsius and an average high nighttime temperature of 22 degrees Celsius. Question 2: Compare and contrast the three regions. What do they have in common? How are they different? Explain.
-
Some of the things these three regions have in common are little precipitation the first couple of months in the year, their daily minimum temperature is lower than their daily maximum temperature, and the majority of the precipitation falls during the summer months. Some of their differences are how much colder NY is from October through May
compared to Florida and Puerto Rico. You can also see that in NY the precipitation never surpasses 5inches. Whereas in FL the month of June sees almost 10 inches of rain. Question 3: Explain the difference between climate and weather based on your course readings and background knowledge.
-
After this week’s readings and the background knowledge I have, I now understand that weather refers to short term changes in the atmosphere whereas climate describes the weather over a long period of time.
