JOURNAL FREE ACCESSIn th previous report the authors got the knowledges of the wind direction ranges and the climatic characters of Yamase-winds from May to August at 1000 JST at Hachinohe Weather Station.
In this report the authors classified the wind directions of 2200 JST by the same method as the previous report and compared with that of 1000 JST.
These results are as follows.
1. The ranges of wind direction and climatic characters of Yamase-winds are qualitatively the same as that obtained in the previous report.
2. The correlation coefficient between the number of days of Yamase and temperature departures from June to July are 0.59 at 1000 JST and 0.71 at 2200 JST.
3. The mean percentages of occurence of all kinds of weather from May to August at 2200 JST show the climatic characters of Yamase-winds better at 1000 JST (Fig. 2, Table 2).
The results of section 1, 2, 3 may be because of the direction of the sea breezes beeing included in the range of Yamase winds.View full abstractDownload PDF (397K) -

JOURNAL FREE ACCESSMany papers on the blooming of cherry-blossoms, in connection with meteorological factors, were published by investigators.
Connecting with this problem, the auther measured the length of peduncle in the period from breaking a bract to blooming date and meteorological factor;
The results are as follows.
(1) The two districts —one of those two districts is Inogashira park (at kichijoji) and the other Kojimachi (at the centor of Toko city)— have the signifficant difference between their mean blooming date.
(2) The author comprehend that the result of eye-observation is reliable comparatively, in comparison with the measured date.
(3) The most affective factor on the blooming date seems to be maximum temperature in that period, and when the maximum temperature exceeds 1°C from 7.05°C the length of peduncle increases 0.35mm.View full abstractDownload PDF (580K) -

JOURNAL FREE ACCESSOn the micro-aircurrent for ealier stage of the silkworms, we have been investigated from standpoint of Gun-San type (Domoro type) silkworm rearing room. We observed the aircurrent of the room with Kata-Thermometer. The results obstained are as follows.
1) The micro-aircurrent of the the silkworm rearing room “Domoro type” is different by silkworm rearing seasonal variation and are represented as following order of their magnitude: summer rearing>auttumn r.>spring r.
2) The micro-aircurrent of the Domoro rearing room is different by larva insecter stage, represented as following order of their magnitude: feeding larva 3rd insecter>1st and 2nd moulting period>feeding larva 1st and 2nd insecter.
3) In general, the micro-aircurrent of the Domoro rearing room is always lower than that of the silkworm normal rearing room. On the 1st and 2nd feeding insecter, the rate of the micro-aircurrent of the Domoro type is about 20-30% in the spring rearing, 62-66% in the summer r., 86-87% in the autumn r. of the silkworm normal rearing room. The Domoro micro-aircurrent magnitude of feeding larva 3rd insecter and 1st·2nd moulting period, We can increase or decrease as well as the normal rearing room by treat of the absorb and expel air-canal.
4) Domoro aircurrent is largest at the forward part, the posterior p. next and the central p. smallest on the horizontal distribution. It is also to note that the vertical distribution is seemingly largest at the lower part, the upper p. next and the middle p. smallest.
5) On the aircurrent difference, the horizontal distribution is always smaller than that of the vertical distribution in the spring and autumn rearing season, but it is seemingly in the reverse order of the summer rearing season.
6) On the 3rd larva stage, we can increase 10% micro-aircurrent by use of the suqqlement canal on the expel air-canal.

(5). Dangerous precipitation and its seasonal occurenceT. NISHIKATA, T. IIDA1955 Volume 10 Issue 3-4 Pages 101-104

JOURNAL FREE ACCESSThe authors investigated the relation between the characteristics of precipitations and soil losses caused by rain on the plots after potatoes and barley harvested, in 1951. From the results it was obvious that the soil loss occured by the rain which showed maximum intensity 2mm per 10 minutes, and increased extremely on 3-4mm per 10 minutes. And the rate of minimum infiltration velocity decreased extremely when the maximum intensity showed more than 2mm per 10 minutes. From these results, considering the frequency and duration of precipitations, it is determined the critial intensity off dangerous precipitator as 2mm per 10 minutes, tentatively.
Then, using the observational data from 1944 to 1951 of the Kutchian Meteorological Station, calculated she seasonal occurence of dangerous precipitations. As the total precipitation, dangerous precipitation and frequency of dangerous rainfall altogether showed the maximum value at September, so it was suggested that this month is the most dangerous for soil erosion, especially at the first decade of the month. As it was observed that among the dangerous precipitations, the rain with the critical intensity (2.0-4.0mm/10min. max.) occurred most frequently, so it was suggested that the soil erosion would be able to control by adequate soil management.View full abstractDownload PDF (643K) -

JOURNAL FREE ACCESSIn 14 Sept. 1954, when the typhoon No. 12 was at Japan sea, we observed the wind over the rice field at Chigasaki, making use of 6 small Robinson cup anemometers installed to the pole of 6m high. The vertical distributions of wind velocity and turbulence were obtained.
The following results were obtained:
(1) The vertical distributions of mean wind velocity were well represented by the logarithmic law,
U(z)=2.30V*/klogz-d/z0,
and the roughness parameter z0 and zeroplane displacement d were found to change in accord with the wind velocity. When the wind velocity at 2m height was within the range 5.5-7.7m/sec, d was reduced and z0 was increased respectively with the wind velocity.
(2) Observations obtained before at other rice fields were also reconsidered, and it was found that, except cases the wind velocity was less than 1m/sec, d was incresed and z0 was decreased respectively with the wind velocity up to 5m/sec, and that, however, when the wind velocity was increased over 5m/sec, d was reduced and z0 was increased respectively. (Fig. 2)
(3) We observed the fluctuation in windy elocity by means of reading anemometer's counter at every 5 seconds. The energy of turbulence ‹u′2› was increased very little with the averaging time ranging from 1 to 30 minutes, and was increased with height. The intensity of turbulence ‹u′2›1/2/U was decreased slightly with height.
(4) Eulerian-correlation coefficients for velocity fluctuation were calculated and the empirical result of R(t)=1-const.t1/3
was obtained.
These results obtained are apparently different from the theoretical ones based on the Similarity theory of Turbulence. These discrepancies might be partly due to the fact that the inertial subrange of turbulence is too small to be observed by the method mentioned above.View full abstractDownload PDF (494K) -

JOURNAL FREE ACCESSIn order to get an effective and economical burning method, especially that of a spacing of oil-burners in a vineyard, we investigated horizontal and vertical distributions of air temperature in the experimental field before and after lighting.
The experiments were carried out at Kikyogahara in Nagano Prefecture on May 19-23, 1953.
In the results of the experiments, we found a good, uniform distribution of the warm zone, with the temperature rise of 1.5° to 2°C in the whole experimental field and of 3°C in the middle, when small tins (the diameter 14cm) were hung at the height of 90cm under the trellis and were spaced in such a manner that there is about one heater in every 4sq meters.

(2) Temperature and heat transfer in the shallow water covered by the frame paperZ. UCHIJIMA, Y. MIHARA1955 Volume 10 Issue 3-4 Pages 113-117

JOURNAL FREE ACCESSThe characteristics af the water temperature under the canopy of framepaper used for temperature arising were studied. The frame papers with various heat transmissivity were stretched on the shallow ponds of 5 and 10cm depths, and temperatures of water and sub-soil were measured.
On the amplitude of diurnal temperature change of water, the following relation was obtained,
RΔT=1+0.021s⋅T
where, RΔT is the ratio of the amplitude under frame paper with various heat transmissivity T to the calculated amplitude of temperature change caused by air temperature by means of heat transfer, s amplitude of the incident radiation.
The constant (0.021) may generally vary with intensity of heat transport to the above air layer and the thermal properties of water and soil layer, but the variance of the constant will be slightly, because the transport of heat through the frame paper will not change so largely with air conditions and the thermal properties are constant. So above relation will be applicable to the temperature condition in the ordinary hot beds.
The heat transfer at interface of bottom in both the water covered by the frame paper and “free” water was compared. As the frame paper extremely obstructs the heat loss from water to the lower air layer and the disturbance of water layer by air motion, Gr's number becomes very small compared with that of “free”. Consequently, from the following relation, it is expected that heat transfer coefficient interface of the bottom in the covered is very small.
α=a(Pr⋅Gr)1/3, 1/4
where α: heat transfer coefficient, a: constant, Pr: prandtl's number, Gr: Grashof' s number.
When we compute the value of Micrometeorological Charaterristic Index (R=ΣL/ΣB; H. Lettau) at the interface of the bottom of 10cm deep, R becomes -1.5 in the covered pond and 0.53 in the “free”.View full abstractDownload PDF (745K) -

JOURNAL FREE ACCESSSome properties of frost action on a plant may be studied experimentally in the laboratory by means of the most easy way of cooling by conduction in contact with the freezing mixture. In this case however the temperature on the frost forming surface of the plant is higher than in the inside tissue of the plant when cooled down under the clear night sky. It is a matter of great difficulty to realize the noctual cooling passage taking place in the open field by introducing radiative cooling process in the closed chamber. The nuisance to get rid of arises from the frost formation on the outer wall of the cooling apparatus which prevents the cooling surface from frost deposition, our object really wished for.
The 1st type of our apparatuses worked out consists of 2 concave aluminium mirrors facing each other at a little distance and the freezing mixture (or dry ice) and the surface to be frosted are put on each focus of the mirrors as shown in fig. 3, (or a hollow ellipsoid coated inside with gold is possibly better). The experimental test of this apparatus is not mostly satisfactory principally owing to the small scale apparatus as well as imperfectly refecting surfaces.
The second type consists of 4 glass cylinders of different diameters as shown in fig. 4, CC cylinder being protected by means of thermally insulating wool cloth and humid or dry air flows into its enclose space through 4 small holes EE……and flows down through G, G. The middle part of the innermost cylinder is used as the cooling surface mape evident by the figure of a plant leaf. The cooling curves obtained by this cooling apparatus are shown in fig. 5 in which a fine lined cooling curve is due to the inflowing humid air and a quick temperature rise marked A arises from the sudden freezing of the supercooled drop of dew, and that marked B from that of the plant sap. The other thick lined curve is due to the inflowing dry air in which only one quick temprature rise B is noticeable there because owing to the sudden freezing of the supercooled plant and also owing to no formation of dew. Thus the 2nd type of our cooling apparatus meets demand most sufficiently and may be recommended to some worker in need of the frost investigation.View full abstractDownload PDF (434K) -

JOURNAL FREE ACCESSA thermometer to be examined is usually placed in a thermostat filled with water. In this condition, the thermometer is to show the same temperature, no matter whether it gets the heat from the surrounding water by conduction or from the enclosing walls by radiation.
In the open field, however, the thermometer presents sometimes the erroneous temperature caused by the follwing facts.
1. Differently conditioned surroundings, for example, heat radiation from clouds overhead, obstacles nearby and atmospheric water vapors etc.
2. Dimension of the bulb, i.e. the relation of radiation to conduction differs by the radius of the thermometer bulb.
3. Wind velocity, which deprives of heat from the thermometer by conduction.
Though the exact temperature of air is hardly obtainable by and means of the current instrument, the considerations above made are confirmed by thethermometer being subjected to the varied conditions.View full abstractDownload PDF (564K) -

JOURNAL FREE ACCESSOur experiment was made in October 10·11 and 26·27, 1954, to see the effectivity of irrigtion for protecting frost injury of paddy rice.
Observed elements are as follows: Air temperature (Height: 10, 20, 40, 60, 80, 100cm), Earth-surface temperature, Water temperature of paddy field and stream. Wind velocity (Height: 10, 20, 40, 60, 80cm)
Weathers of observed days were clear and calm or light breeze (Table 1). Vertical distribution of temperature are showed in fig. 1 and are ground inversion types have minimum temperature at a height of 20, 40cm on the ground surface of no plant.
The effect of irrigation reached about 40, 60cm in height. Air temparature at 100cm on the irrigated paddy field was generally higher than that of the non-irrigation and this reason is unknown. But suppose both temperatures are equally, we can know the effect of irrigation in comparison of air temperature at 100cm with at each height. This result is shown in fig. 2. From this figure it is seen that the effect of irrigation reached 60, 70cm in height.
Therefore it is impossible that padddy rice keep perfectly from forming of frost by this irrigation method, but possible by using jointly the smoking or combustion method.View full abstractDownload PDF (368K) -

JOURNAL FREE ACCESSWe solve green powder named Salivap Green in the sea-water for the purpose of promoting evaporation when we make salt from the sea-water. To know the relations between the evaporation and the concentration of the solution under natural conditoins, we put the same vessels (diameter 12cm., depth 2cm., depth ofthe solution 15cm.) of four kinds of the solution which concentration of Salivap Green is 1/1000 (A), 1/10, 000 (B), 1/100, 000 (C), and O (water) (D), respectively, on the concrete ground. We measure the temperature of the solutions by the thermocouple and those evaporation by the balance. As is well known, the following expression for the evaporation E is given.
E=f(v, R)(es-e)……(1)
where v is the wind speed, R depends on the seize and the form of the water surface, f(v, R) has no definite expression, es is the maximum vapour tension corresponding to the water temperature, and e is the vapour tension above the water surface. According to our observations, dense solution has the high temperature and so the evaporation increases by (1). The evaporation ratio (to D) is 1.87 (A), 1.63 (B), 1.17 (C), and 1.00 (D), respectively. The ratio (es-e) to D is 1.62 (A), 1.35 (B), 1.06 (C), and 1.00 (D), respectively. If we assume be constant, the evaporation ratio must be equal to the ratio (es-e) by (1), But our observation shows that their discrepancies increase as their temperatures become high. This mean that f(v, R) increases as the temperature become high. This results from the natural convection by the density difference of atmosphere due to the high water temperature. We, furthermore, examine the absorption coefficient of the solutions for the insolation. The thickness of the bottom of glass vessel is dg and its absorption coefficient is kg. If the depth and absorption coefficient of the solution is d and k, we have the following expression.
I=I0e-(kgdg+kd)
Ig=I0e-kgdg k=-1/dln-I/Ig……(2)
I0, I is the incident and transmitted ray and Ig is the strength of the transmitted ray (when the water depth is zero) of glass of the bottom. k increases slowly as the concentration approches to 10-5 (C) and thereafter increases abruptly. As regard to the absorption, absorbed energy is I0 (1-e-kx).
x, k is the thickness and absorption coefficient of the solution and I0 is the strength of the incident ray. Then we can see that the effect of raising water temperture is not conspicuous in proportion to the increase of k when k is comparatively large.View full abstractDownload PDF (466K) -

(2) Effect of roller pressing on the control of wind erosionS. TANAKA, S. KAKINUMA, H. SANO, T. TANIZAWA1955 Volume 10 Issue 3-4 Pages 139-142

JOURNAL FREE ACCESSWe carried out an experiment with the effect on wind erosion prevention of the roller pressing upon the clean-tilled wheat field.
1. Moment of resistance of the soil.
The resistance near the surface of the ground is remarkably greater in the area pressed by the roller than in the area pressed by foot. However, no noticeable difference is found in the depth of 11 or 12cm. It indicates that the cultivation has reached up to that depth. As to the deeper part, the moment of resistance of the soil itself is shown. The increase of moment of resistance heightens the separation resistance and the drag resistance, and it shows that non-erosiveness is also greater.
2. Water contained by the soil.
The amount of water contained in the surface soil in the roller-pressed area is a little more than in the foot-pressed area. That is considered to be due to the fact that the pressure has decreased the porosity of the soil and facilitated the rising of the capillary water.
3. Nature of the surface.
The projection of the earth on the surface is 0.3-0.5cm. in the foot-pressed area, and 4.0-5.0m. in the footpressed. The condition for the starting motion of the soil particles is that the force that the particles get from the wind becomes equal to the static frictional pressure on the particles. Then the friction velocity when the particles start to move is represented by
V*t=A√σ/ρgd
In the case of the roller-pressing V*t is smaller and the more nonerosiveness is to be found than in the case of the foot-pressing.
4. Amount of flying soil.
The amount of flying soil in the roller-pressed area is very little, 26% of that in the foot-pressed. In the time when frost forms in the ground, the amount is small in either area, and the difference is little. Consequently, it is concluded that the roller-pressing is most efficacious at the period from March to the beginning of April, when frost ceases to fall.View full abstractDownload PDF (569K) -

JOURNAL FREE ACCESSThe expeiment with the wind erosion was carried out on clean-tilled wheat field and the kittatemaki field (that is, wheat field sown on fallowed soil in use of stubbles of the previous crop).
1. Wind velocity
By the investigations of the horizontal distributions of wind velocity, it was made clear that the clean-tilled field and kittaternaki field were below the similar condition of wind.
On the ridges in the kittatemaki field, the wind velocity decreased vertically about up to the height of 45cm. As for the influence of particular ridges on vertical distribution of wind velocity, the velocitybecomes constant at about the fifth ridge from the windward. The nature of the surfaces of both fields is as tabulated hereunder, according the formula of the curve of vertical distribution of wind velocity-:
U(z)=5.75U*logz/K
It is remarkable that the value of U* is very large, and this is thas the value is the total friction velocity of the surface and the ridge.
U*……Total friction velocity of surface and ridge,
U′*……Friction velocity of ridge.
U*-U′*=U″*
The above formula is the friction velocity of the surface soil. The following is the deduced value.
U″*=17.4m/sec
According to the formula of the coefficient of resistance (CX),
ρU*21=1/2ρUm2C×hd+ρV″21
∴C×=0.28
This means that the ridge makes the wind velocity required to the initial movement increase almost by 1.70 times of the soil.
2. Soil moisture
The quantity of water contained near the surface is less from 4 to 6% in the clean-tilled field than in the kittatemaki field. The causes are considered to be (1) the cutting-off the capillary tubes owing to tillage, (2) the exposure of the surface soil to the wind, and (3) the limitation of sunshine by the ridge, and so forth.
3. Flying soil.
The quantity of flying soil in the clean-tilled wheat field amounts to more than 4 to 5 times of that in the kittatemaki field. As regards the height distribution of flying soil, in the case of the former the majority of the particles near the surface are of great diameters, but according as the height increases, particles of small diameter are found to increase. On the other hand, in the case of the latter the diameters do not vary according to the height from the ground.
This shows that in the clean-tilled the flying soil is mostly from its own surface, while in the other it consists mainly of the soil carried from the fields to its windward.View full abstractDownload PDF (543K) -
