Abstract

A verification was conducted on the micrometeorological function of paddy fields that control temperature conditions. A movement measurement was executed in order to elucidate air temperature distribution in the paddy field area. The observation revealed the following matters: air temperatures over paddy fields and farm lands are lower than those at bare lands and paved areas; air temperatures downwind the paddy fields are lower than those in residential areas; and air temperatures on the paddy fields are lower than those on the farm lands. Measurement of the air temperature distribution in paddy fields revealed that a paddy field becomes a heat absorbing source in the process of breeze blowing over the paddy field, and alleviates the temperature environment in the downwind area. A discussion was given on the specificity of surface temperature of the paddy field from the above result. It is the feature of paddy fields in summer that the energy exceeding the radiated amount is distributed into latent heat around the noon of a day. The surface temperatures are in the decreasing order of non-irrigated bare land > irrigated bare land > atmometer water surface > farm land > paddy field. The upper limit for the paddy field  More>>

It is the feature of paddy fields in summer that the energy exceeding the radiated amount is distributed into latent heat around the noon of a day. The surface temperatures are in the decreasing order of non-irrigated bare land > irrigated bare land > atmometer water surface > farm land > paddy field. The upper limit for the paddy field surface was around 28{degree}C. Surface temperature forming factors were discussed, and the surface temperature parameters (relative humidity, evaporation efficiency, etc.) were derived on each type of the land surface. The surface temperatures on each land surface were calculated using the parameter values. The result revealed that a paddy field having high relative humidity and evaporation efficiency has an effect to suppress the surface temperatures. 6 refs., 10 figs., 1 tab.}
