The quotation is from Tannehill's classic book on drought, published in 1947. Three decades have passed since Tannehill expressed this view. Millions of items of terrestrial and extra-terrestrial weather data have been collected. The computer now allows us to analyze these data with great rapidity. Have the advances which Tannehill suggested actually materialized? My purpose here is to evaluate our current ability to predict drought, as well as to assess the feasibility of achieving an improved capability in this field within the next decade.
