Hurricanes as a Phenomenon
This course will be focused on the physical properties of matter and the interaction of matter with energy.
Fundamental ideas include mass, weight, volume, density and pressure along with kinetic, gravitational and solar energy.
Those will then be applied to understanding weather, climate, tectonic plates, solar system, seasons, etc.
There will be a series of phenomena used to explore these ideas on the time scale of a day or two.
The phenomenon of hurricanes will be used to organize our initial exploration.

Hurricanes
Hurricanes are a dramatic example of weather.
They can be up to 1500 kilometers wide.
And release more energy than 10,000 nuclear bombs.

Hurricanes
These storms are called hurricanes if they occur in the:
•
•
•
•
Atlantic Ocean
Caribbean Sea
Central Pacific Ocean
Northeast Pacific Ocean
This hurricane is off the coasts of Florida and Cuba.

Typhoons
If the same type of storm were located in the northwest Pacific Ocean, it would be called a Typhoon.
This typhoon is impacting Japan, Korea and China.

Cyclones
It would be called a Cyclone if located in the Bay of Bengal or the Arabia Sea. This cyclone is impacting India and the Philippines.

Hurricanes in Northern and Southern Hemispheres
Hurricanes, typhoons and cyclones can occur in the northern hemisphere or the southern hemisphere.
This one is taking place off the cost of Brazil.

Questions About Hurricanes
The following questions will be answered as we do experiments and activities. We will not answer them now, we will just start to think about them.
14
When do Hurricanes Form?
Question 1:
The peak season for hurricanes is:
• August and September in the northern hemisphere.
• March and April in the southern hemisphere.
Why?
15
Where do Hurricanes Form?
Question 2:
Hurricanes form over oceans.
They never form over land.
Why?
16
Some Questions about Hurricanes
Question 3:
Hurricanes always spin counterclockwise in the northern hemisphere, and clockwise in the southern?
Why?
17
Where do Hurricanes Form?
Questions 4:
Hurricanes form in the northern or southern hemisphere.
They never form near the equator.
Why?
18
Some Questions about Hurricanes
Question 5:
Can we predict when and where hurricanes will occur?
How?
19
What is the Energy Source for Hurricanes?
Question 6:
Hurricanes usually last about nine or ten days.
A peaceful ocean suddenly generate a massive storm releasing the energy of up to 10,000 nuclear bombs, and then become peaceful ocean again.
Why?
Where does the energy come from?

Weather and Climate
Question 7:
What can hurricanes teach us about weather and climate?
