A Method of Prediction of the Rainfall Amount in Baiu Season and the Summer Temperature at Hokuriku-district (Preliminary Report)

[摘要] Using the mean isobar types in April, a method of the prediction of rainfall amount in Baiu season and summer temperature is studied in this paper and obtained the following results:(1) Mean isobar types were classified according to the following types of rainfall amount in Baiu season as: 50mm_??_70mm (Fig 1), 100mm_??_120mm (Fig 2), 150mm_??_175mm (Fig 3), 175mm_??_225mm (Fig 4) (mean year's-type), 225mm_??_275mm (Fig 5), nearly 300mm (Fig 6) and 350mm_??_385mm (Fig 7).Generally speaking, the rainfall amount becomes larger as the front becomes more distinct.(2) The mean summer temperature is indicated by the difference of energy between the travelling high from the continent and Ogasawara high. When the both highs are in equilibrium, the summer temperature is the same as the mean value.
