Meteorology
There are local winds in many places in Japan, which is produced mainly by steep topography. Local people recognize that the local winds play an important role in determining daily weather. In particular, local winds sometimes cause precipitation. While the major cause of local winds is topography, it is also recognized that topography of island affects wind speed and direction. But it is not fully clear how the local topography of island affects local winds. Hence, in this project, we will explore local winds at Yakushima where the annual precipitation is maximum in Japan by measuring meteorological quantities such as wind and temperature at multiple locations. Particularly, we will examine spatial relationship of wind and discuss causal relationship of precipitation in association with winds by analyzing observed data.
