Chris Dolce – The Weather Channel… 1900-early August 2011 27 “billion dollar storms” 8 of the “top ten” occurred since 2004 7 surpassed $10 billion mark..
6 of those 7 occurred since 2004 3 rank in $10-$20 billion range…
Ivan & Charley (2004) & Rita (2005) 3 rank in $20-$30 billion club
Andrew (1992), Wilma (2005), Ike (2008) 1 at $108 billion damage – Katrina (2005) Hurricane Sandy – 2nd place at $65 billion in
damage

Grade 6:4. Many phenomena on Earth’s surface are affected by the
transfer of energy through radiation and convection currents. (d, e)
7. Scientific progress is made by asking meaningful questions and conducting careful investigations. (a, d, h)
Grade 7:7. Scientific progress is made by asking careful questions and
conducting meaningful investigations. (a-e) Grade 8:
1. The velocity of an object is the rate of change of its position. (a-c)
9. Scientific progress is made by asking meaningful questions and conducting careful investigations. (a, f)
California Science Standards
California Science Conference 2013Satellite Educators Association Tracking Hurricane Sandy - 22
Grades 9-12: Physics3. Energy cannot be created or destroyed, although in many
processes energy is transformed to the environment as heat. (c)
Grades 9-12: Chemistry7. Energy is exchanged or transformed in all chemical reactions
and physical changes of matter. (a, c) Grades 9-12: Earth Sciences
1. Heating of Earth’s surface and atmosphere by the sun drives convection within the atmosphere and oceans, producing winds and ocean currents. (a, b, d)
Grades 9-12: Investigation and Experimentation1. Scientific progress is made by asking meaningful questions and
conducting careful investigations. (a, d, i)
