Hurricane Tracker – Intro/Sandy

Sandy’s (2012) Track With a partner, explore Sandy’s track... Positions are ___ hours apart. Maximum size (Category) on the Saffir-Simpson scale? When and where? When and where was landfall in lower 48? Wind speed then? Where and when was the hurricane moving the fastest? Other interesting observations?

Assignment With a partner, examine historic hurricane tracks: How many hurricanes made landfall in New Jersey ? Recurrence interval (average time between hurricanes) in NJ? – = total years / # hurricanes – (e.g., 150 years / 10 hurr = 15 years/hurricane) Recurrence interval of major hurricanes in New Jersey? If you have time: – How many hurricanes have come within 50 miles of your town (or a specific town you are curious about)? Make a list of hurricanes that may have affected your area. – Describe the frequency of different size storms. – The storm distribution through time is also shown on the bottom axis. Do you see any patterns? OR

Sandy’s (2012) Track With a partner, explore Sandy's track... Positions are ___ hours apart. – Answer is nuanced: many positions are six hours apart. However, not all positions are six hours apart. This may lead into an interesting discussion of why. (There might be more time between positions on land because the storm stalls, or less time between positions going over Caribbean Islands because of a desire on the part of the person making this plot to show landfall.)

Sandy’s (2012) Track Maximum size (Category) on the Saffir- Simpson scale? When and where? – Hurricanes are classified by the highest category they reach. Sandy reached Category 3 when it made landfall in Cuba.

Sandy’s (2012) Track When and where was landfall in lower 48? Wind speed then? – Brigantine, New Jersey. 80 mph (Category 1).

Sandy’s (2012) Track Where and when was the hurricane moving the fastest? – Sandy gathered speed and increased to a Category 2 for several hours on October 29 as it traveled over the Gulf Stream, and just before making landfall in New Jersey.
