On the Water Temperature of the Lake Nisi (Fuji-goko)

[摘要] The result of investigation on the wa_??_er temperature of each layer of Lake Nisi is as follows:1) The surface temperature has the maximum value 24.1°C in July, the min. value 4.4°C in Jan. an_??_ the annual range is 19.7°C, while in 70m depth the temperature has max. value 5.3°C in Dec., min. value 4.2°C in Feb. and the anuua_??_ range is 1.1°C.2) The heat transfer is, in the surface layer, large in case of temperature increase and small in case o_??_ temperature decrease, while in d_??_ep layer the conditions are reversed.3) The layer of jump is most conspicuops in 11-13m depth in September and its gradient of temperature is 0.99°C/m.4) The normal deviation of deep layer temperature in Summer season shows the good correlation with the meteorological conditions of the last Winter.
