Hurricanes Why do we care about hurricanes? What was the biggest hurricane you heard about recently? Where did it make landfall? What damage occurred as a result? What causes the damage?

What are these water features called? Can you think how the may be created?

History Lesson: 1938 Hurricane Long Island  700 deaths, 708 injured  4,500 homes, cottages, farms destroyed; 15,000 damaged  26,000 destroyed automobiles  20,000 miles of electrical power and telephone lines downed  $2,610,000 worth of fishing boats, equipment, docks, and shore plants damaged or destroyed  Created the Shinnecock Inlet (Hampton Bays, NY)

What is a Hurricane?  A strong storm of tropical origin, with sustained winds exceeding 74 mi/hr (119 km/hr)  Also known as Typhoon in North Pacific, Cyclone in India, and Tropical Cyclone in Australia  Have an intensity scale to associate wind speed with damage. What can you tell me about this scale?

Saffir Simpson Scale  Tropical Depression mph to 38 mph  Tropical Storm – 73 mph  Category 1 Hurricane — mph  Category 2 Hurricane — mph  Category 3 Hurricane — mph  Category 4 Hurricane — mph  Category 5 Hurricane — 156 mph and up Faster winds = greater damage Question: What is the most dangerous part of the storm other than the winds????

2005 Hurricane Season Video

What is needed for hurricane formation? 1.Humid air 2.Warm ocean water 3.Weak Jet Stream – strong causes shearing, which hurts development 4.Line of thunderstorms - tropical wave that can merge together and form a series of convection cells (weather systems)

2005 Worst Hurricane Season on Record!!!! But Why????  Record 28 tropical and subtropical storms formed tropicalsubtropicaltropicalsubtropical  Record 15 became hurricanes  Record-tying 5 became Category 4 hurricanes  Record four reached Category 5 strength (the highest possible)

Do Now (on index card)  Put answers to homework on one side (pg 129 – 130 # )  Answer the following questions on the other side (using your book and notes): 1.How do hurricanes get their energy? 2. Why do we care about hurricanes? 3.What is necessary for hurricane formation? 4.Was the storm that passed a hurricane why or why not?

How a Noreaster Develops

What is the difference between a Noreaster and Hurricane?  Hurricane - A strong storm of tropical origin (low pressure) with sustained winds exceeding 74 mi/hr (119 km/hr)  Noreaster – Coastal storm (low pressure) caused by a arctic high pressure meeting a warm low pressure system, usually has E to NE winds

Noreasters and Port Jeff How could a Noreaster affect the area of Port Jeff? Hint: Think about what hurricanes do to the South Shore of Long Island

What could I use to make a scale model to show what storm surge is? Storm Surge – wind piling water up on coastal areas causing flooding

What does storm surge do?

How do we prepare for Hurricanes or Noreasters?  Having emergency supplies of water, food, lighting, heat, and back up power  Evacuate the coastal areas – move inland  Move to higher ground or to the second floor Why would be going in the basement be a bad idea???
