Abstract

The automated Weather Phenomenon Observation System can observe condensation and record the occurring time of weather phenomena by using image identification technology. The time of condensation occurring and the data of soil moisture in the shallow soil layer are analyzed, and the inverse relationship between dewfall time and shadow soil moisture is confirmed by using the data of the automatic present weather observation system and soil moisture observation equipment installed at Pinggu Station in Beijing from April to September in 2011. The condensation phenomenon appears earlier when the soil moisture of 0 to 10cm layer is higher. On the contrary, the condensation phenomenon appears later when the soil moisture of 1 to 10 cm layer is too low. It can be used to predict soil moisture by exploring the timing of dewfall via the automated Weather Phenomenon Observation System, which is useful to monitor drought.
