Abstract

Observations were made from a tall tower for the nine years from 2000 to 2008 to analyze the climatic characteristics of the Fujiyoshida forest meteorology research site. Annual mean global solar radiation, air temperature, vapor pressure and wind velocity were 14.1 MJm^-2 d^-1 , 9.5ºC, 1.07 kPa and 2.1 ms^-1, respectively. Annual precipitation was 1955 mm. The prevailing wind direction was south-southwest. The shape of the hythergraph for the site was similar to that for the Yamanaka AMeDAS station. Global solar radiation in summer was lower than that recorded at nearby weather stations, which is considered to be explained by the presence of fog and cloud because of the high elevation. It is suggested that the Fujiyoshida site has sufficient radiation and precipitation for vegetation growth according to climate classification and a climatic net primary production estimation model.
