| Summary: | P(論文) Studies have been made of seasonal variations of meteorological elements at Syowa Station and Mizuho Camp. From the spectrum analysis of time series data of air pressure, wind speed and air temperature at Syowa Station and Mizuho Camp, the following are found : Katabatic wind speeds and air temperature at Mizuho Camp have each a good correlation with air pressure at Syowa Station in a cycle of about four days; a seasonal variation of each katabatic wind and air temperature at the camp coincides with that of air pressure at the station resulting from the synoptic scale disturbance. The studies also disclosed : A seasonal variation of air pressure at the station caused by a synoptic scale disturbance corresponds to a seasonal variation of moisture flux from the sea into Mizuho Plateau; the monthly means of both wind speed over the surface inversion layer and horizontal moisture flux from the sea to the continent became maximum in September 1972,when the synoptic scale disturbances became strong; the seasonal variation of horizontal moisture flux at the level corresponding to 700mb above Syowa Station shows a fairly good correlation with that of net accumulation of snow at Mizuho Camp. departmental bulletin paper |
