抄録

In this paper, the author discusses the change of local sea-level pressure system in Central Japan from January 18 to 21, 1991, by using the hourly observation data of sea-level pressure.<br>After the passage of synoptic-scale cyclone, at around 09 JST (Japan Standard Time) on 18, local low-pressure areas in the southeast of the mountainous areas in Central Japan are generated, where local cyclones are formed. On the evening of 18, a local high-pressure area in the northwest of the mountainous areas in Central Japan is generated, where the local anticyclone is formed.<br>From January 19 to 20, the local sea-level pressure system shows the diurnal change. Not only the nocturnal local anticyclone but also the daytime local cyclone are generated even in winter. That is, on the evening of 19, the local anticyclone centered at Takayama is generated. At around 06 JST on 20, it is most developed, but before noon it declines. Then the local cyclone centered at Matsumoto is generated and most developed at around 15 JST. On the evening of 20, the local anticyclone is again generated.<br>However, in spite of the daytime heating, the local cyclone is not immediately generated and developed. Thus the heating and cooling on the surface of Central Japan cannot merely cause this diurnal change.
