There are few other weather phenomenon which effect a country’s agriculture, economy, and people greater than the Monsoon. The monsoon is defined as a seasonal reversing of wind accompanied by a significant change in precipitation. For many parts of the world, and particularly south Asia, the monsoon provides much needed rainfall. However, the amount of rainfall and number of tropical storms brought about by each year’s monsoon has been extremely difficult to predict. Scientists from the International Pacific Research Center at the University of Hawaii at Manoa have made a breakthrough for predicting the summer monsoon rainfall over East Asia as early as the spring of that year.
