Abstract: To study the relation between the air temperture in the observation field and barley field is very important when the air temperature at the weather station is applied on the crop cultivation.This study was caried in the experiment field of the branch of industrial meteoralogy section at Owada-cho, Saitama prefecture.We observed the air temperature in the observation field and barley field on the same height with it to compare with them.The relation between the air temperature (X) in the observation field at 10 o'clock from February to June and that (Y) in the barley field is shown as the following formula. (cf. figare 1.)Y=0.5+X+5×10-6e0.58xmean error ±0.7°CAn error of the air temperature in the barley field calculated by this formula is shown as follows in each monthFebruary ±0.4°C March ±0.6°C April ±0.8°C May ±0.9°C June ±0.6°CWe found from Fig 1. that the relation between the air temperature in the observation field and barley field change with the growth of barley.Next we compared with the various air temperature in the observation field and barley field from May 1st. to June 6th. The results are as follows; (cf. figure 2).Minimum temperature in clearY=1.08X-1.8 ±0.7°CMinimum temperature in cloudy or rainyY=1.26X-3.6 ±0.4°CMaximum temperature in clearY=1.17X-0.6 ±0.6Maximum temperature in cloudy or rainyY=1.1X-0.2 ±1.2Diurnal range, clear Y=1.38X ±0.9°CDiurnal range, cloudy or rainyY=0.04+0.98X ±0.5°C10 o'clock clear Y=0.05±1.1X ±0.7°C10 o'clock clear Y=1.9+0.9X ±0.2°CFrom the above results we found that the air temperature in the barley field was clearly higher than that in the observation field except minimum temperature and diurnal range of the air temperature was exceedingly larger in the barley field than the observation field. The mean error of the air temperature in the barley field that was calculated by above formula was within 1°C.
