Abstract:
In order to ascertain the production of soil condensation water in the typical region of North China Plain, the weighing method was used to observe soil condensation water in the study area. The results indicated that the formation of soil condensation water can be observed from 2:00 pm to 10:00 am of the next day. Most of soil condensation water originated from the air vapor and only a small amount from soil water, of which about 50% of the total condensation water gathered in the range of 0 to 5 cm below the ground surface. According to the analysis results of impact factors for the formation of soil condensation water, high relative humidity, low atmospheric temperature, and low wind speed were favorable for the formation of the soil condensation water.
