Barometric Pressure: It is the pressure exerted by the atmosphere, measured with an instrument called the barometer in units called mb (millibars).

Knots: is how the speed of aircraft and boats is measured. Both “miles per hour” and “knots” is a speed, which is the number of units of distance that is covered for a certain amount of time.

1 knot = 1 nautical mile per hour = 6076 feet per hour1 mile = 5280 feet

Tropical Depression: an area of heavy rain and winds, first stage in the development of a possible hurricane with wind speeds less than 38 mph.

Tropical Storm: Organized center of low pressure with sustained winds of 39 to 74 mph.

Hurricane: Violent, tropical cyclonic storm with sustained winds of 75 mph or higher.

Cape Verde Islands are located at 25 degrees west and 16 degrees north of the equator. 1 degree of longitude/latitude is approximately equivalent to 70 miles.

Conditions for storm development:

  1. Low barometric pressure
  2. High ocean water surface temperature
  3. Water vapors (created when hot water evaporates and, due to low barometric pressure, rises to the atmosphere).

To be completed and discussed in the group. :

  1. You will have two Hurricane Tracking charts; one will be to track the four hurricanes and the othe one will be used for the weather report.
  1. Use one Hurricane Tracking blank chart provided by your teacher to plot the five points of each of the hurricanes A, B, C, and D and connect each of the points using a curvy line, NOT a straight line. Use a different color or line design to connect the dots and differentiate each of the hurricanes.
  1. Explain your rationale to assign latitude and longitude values to the correct corresponding axis on the hurricane-tracking chart.
  1. Study the data from the hurricanes table for each of the hurricanes and compare it.
    Which information seems to repeat for each storm?
    Which information is unique for each storm (what makes them different)?
  1. What conclusions can you infer from the discussed information?
  1. Study the information received regarding the disturbance off the coast of Cape Verde Islands.
  1. The disturbance is located 70 degrees west of the Cape Verde Islands.
  2. Current barometric pressure is 990mb and dropping 12mb every 6 hours.
  3. Ocean water surface temperature is 84 degrees and rising 2 degrees every 6 hours.
  4. Water vapors convection is increasing.
  5. The current month is named for whom, after defeating Marc Anthony and Cleopatra, became the Roman emperor.
  6. Discuss with your teammates whether the conditions for this disturbance are ideal for a storm to develop.
  7. If it’s a group decision that a storm will not develop, provide a rationale or fully detailed explanations for having reached that conclusion with supporting arguments.
  8. If it’s a group decision that a storm will develop, continue with the questions that follow below:
  9. What name would you give this storm?
  10. How could you use the information on the table to estimate wind speed?
  11. How could you use the information on the table to estimate its location on the chart:
  12. 12 hours from the original point of the disturbance?
  1. 24 hours?
  1. 36 hours?
  1. Make a list of all the information you need to present in your report. What details do you need to include and talk about?
  2. Can you specify whether after 12 hours this event is a Tropical Depression, a Tropical Storm, or a Hurricane? Why or why not?
  3. Use all the details you think can help you from this worksheet to develop a brief, but precise and concise weather report on this storm to present to the person(s) who requested it.
