Water vapor is an important factor to the formation of small and medium-scale disastrous weather. Its temporal and spatial variation is extremely violent and uneven in the air. Therefore, the development of a real-time monitoring and analysis system for dynamic variations characteristics of spatial and temporal water vapor has great practical significance and application value to short-impending rainstorm forecast. The GNSS/PWV dynamic changes monitoring and analysis system was built on the Matlab platform. Based on the calculated PWV of every CORS reference station, it can be used to demonstrate the time series analysis and planar dynamic changes of various kinds of meteorological elements (PWV, temperature, barometric pressure and relative humidity, etc.). Especially, it can accurately reflect one and two dimensional dynamic trends of the water vapor within the CORS coverage area, track the dynamic changes of atmospheric water vapor content and enhance the monitoring and forecasting capabilities of meteorological departments for small and medium scale disastrous weather.
