On the forecasting of the Mei-yu in Taiwan

Ming-Tung Hsu, Shui-Shang Chi

Abstract

　　Mei-yu (or Bai-U) is the name of the season of heaviest rainfall in the Yangtz River Basin and in southern Japan. It is also observed in the north Taiwan and Ryukyu Islands. The Mei-yu period in these areas is slight different from the above areas. In this transition season of spring to summer, it is almost always overcast with intermittent or continuous rains, sometimes, it even becomes heavy rains which terribly affect the plant growth, the rice harvest and our daily life. Hence, developing a number of methods for forecasting the Mei-yu in this island is the most urgent task for research works.
　　This is a successive report after “On the analysis of Mel-yu in Taiwan” written by the same authors in 1974. The essential content of this paper is the brief analysis of Mei-yu and the several methods such as corelation field, semiemperical, time series analysis and analogue which might be useful for the forecasting of the Mei-yu rains in Taiwan.
