Abstract:
A method for recognizing and automatically processing rainfall records resulted from snow melting from regional automatic observation stations in winter is introduced in detail. The recognition is divided into two processes: snowfall and snowmelt. Under the premise of snowfall, the selected station has a record of rainfall, and it is in accordance with the condition of melting snow. According to the inspection, the automatic recognition accuracy rate is as high as 90%. The temperature of regional automatic observation stations is used as the main condition of snowfall and snow melting, combined with the data of national meteorological observation stations and the comprehensive judgment. In order to improve the recognition of weather conditions and the nature of precipitation, the radarestimated precipitation, winter precipitation phase discrimination, and other products are also added to make up for the defects of a single reference station for precipitation data, which is of significance to the recognition of snowmelt and rainfall records.
