   The example you decribed, put in other words, says:   
      
   Suppose I have evidence from 2 independent sources on weather forecast.   
      
   The mathematical theory that is designed to tackle the combination of   
   such information is evidence theory. For example, I can point you to   
   Dempster's theory. Since you are a novice, I will not suggest some   
   specialized book or article, I think that searching on the web for   
   Dempster, Dempster & Shafer or Dempster & evidence you will be able to   
   find some simple examples on how to apply the theory.   
      
   I hope this helps..
