5. Remarks 

 I have presented my conclusion with the reference to the secular 

 change of climate in Japan, attempting to make clear the controlling 

 factors of this change. The problem may be very important related 

 with " Weather Forecast." I wish to express my deep thanks to Dr. 

 K. Wadati, Director of Central Meteorological Observatory of Japan, 

 who extended me a great deal of kind help.
