JOURNAL FREE ACCESSAn energy conserving atmospheric model is obtained by introducing the changes in the general field due to non-linear interaction of a disturbance which is governed by a linearized system of equations. Numerical integrations are made on meso-scale disturbances.
This model is characterized by the static sta b ility change caused by non-linear heat transport, which in turn determines the life cycle in the growth of disturbances.View full abstractDownload PDF (903K) -

JOURNAL FREE ACCESSIn the meteorological field, correlation analysis has been performed for cases containing several continuous variables only. On the other hand, AITKEN, A. C. and GONIN, H. T. (1935) previously studied the moment generating function in the fourfold sampling procedure. Moreover TATE, R. F. (1954), OLKIN, I. and TATE, R. F. (1960) recently gained the several interesting results concerning the correlation analysis approach in cases where both continuous and discrete variables are simultaneously taken into consideration.
Therefore in this paper, the author firsly derived several supplementary results from the correlational expressions gained by OLKIN and TATE and drafted a diagram to serve statistical large sample test of sample correlation coefficient, and secondly contrived to draft statistical diagrams of large sample test to correlation coefficient through formal expressions of bi-variate binomial distribution in reference to the past studies mentioned above. Lastly, some possible application examples are shown once at least in the meteorological field, to explain the author's contributions to such statistical fields.View full abstractDownload PDF (2522K) -

JOURNAL FREE ACCESSTWOMEY'S chemical diffusion chamber useful in the atmospheric small supersaturation (1959) was improved in some points and made available for field work.
In th e laboratory small volumes of air were sent into a diffusion chamber and an expansion chamber both in the same supersaturations.
Concentrations and size distributions of formed droplets in both chambers were compared putting several artificial nuclei into them and moreover poisoning effects on nuclei surfaces by gas substances were studied.
In the formation of droplets it was found that not only supersaturation, water content and cooling rate of air, but also the poisoning effect caused by environmental gas substances were important factors. Both surface tension and contact angle of oily gas substances affected droplet formation.View full abstractDownload PDF (2948K) -

JOURNAL FREE ACCESSWind vanes with reduced moment of inertia (one order lower than conventional) are tested in the wind tunnel. The results show a marked reduction in the overshoot amount, or a remarkable increase in the damping ratio. The nature of its effectiveness in suppressing the overshoot is different from that of an oil-damper. The shortcomings of the reduced rigidity can be remedied by utilizing a wind vane of ordinary design, but equipped with a rudder that acts upon the acceleration feedback of the vane oscillation.View full abstractDownload PDF (584K)
