The following link to the El Ni o Table presents information on El Ni o and rainfall for the years from 1947 to 1992. The rainfall column of the table gives the total annual rainfall for Canary Island in northern Victoria. Use this information to answer the following questions. If the SOI value is positive, it means that there was no El Ni o event in that year. See the SOI graph for the current values.
Questions Answer the following questions in the spaces provided.
Write down the rainfall for each year that the SOI was less than -10. Calculate the average rainfall for all these years in which the SOl was less than -10. This is the average rainfall in years when El Ni o was present. Write down the rainfall for each year that the SOI was greater than 10. 6. Calculate the average rainfall for all these years in which the SOI was greater than 10. 7.
