Image Processing and Analysis: Weather Forecasting

 backforward

Your task here is to predict based on the data given how many hours until the eye of hurricane Ivan passes over Jamaica. Assume the three images below are the only data currently available. Also assume if Ivan stays on its current course the eye will pass over the very southern tip of Jamaica, marked by a yellow circle on the images.

To complete this task, you should:

  1. Compute the current average speed of hurricane Ivan.
  2. Determine the current distance the eye is from Jamaica.
  3. Estimate the time in hours before the eye reaches the southern tip of Jamaica.

Part 1: Compute average speed
  • Press the speed button to activate speed tracking.
  • Click the eye of Ivan to mark this location.
  • Advance to the next two images and mark them as well.
  • From the two speeds shown, compute an average.
Part 2: Determine current distance
  • Press the distance button to activate distance tracking.
  • Advance to image 3 and click to mark the eye of hurricane Ivan.
  • Stay on image 3 and click the southern tip of Jamaica.
Part 3: Predict the arrival time

time = distance / speed
