Read the data and write an explanation of the economic impacts of an El Niño event.

  • Follow the detailed directions in your Activity book.
  1. Find the 1982/1983 abnormality in temperature measured at the March/April closest to the middle of the graph.
  2. Divide the Deviation from Normal by the Temperature Difference. This gives you a number telling you how much the rainfall should increase for each degree that the sea surface temperature is above normal.
  3. Using your calculations, predict what the rainfall increase will be in Rockhampton, Australia during the March/April period if an El Nino occurred that was 4.1 degrees above normal. (To find the answer, multiply your Rainfall Increase per Degree value times the 4.1 degree increase.)
