Abstract: Based on the revision requirements of the "China Meteorological" mobile decision-making meteorological service, decision-making meteorological service products, and real-time monitoring and forecasting information can be quickly obtained through the mobile communication network. The nine functional modules have been re-planned to realise automatic positioning, data automation access, data querying and ranking statistics in order to complete the mobile phone decision-making weather client upgrade revision. Through the revisions, the China Meteorological Administration realised at all levels of business units of data and service products, and automated access to CIMISS system weather station monitoring data. This will ensure the system released weather data and weather service products are released in an ef ficient and timely manner. This is the first time the display to the mobile client has been synchronised, which enhances visual services products, thereby improving the visualisation of results. This will allow for the decision-making users to be contacted in cases of major meteorological disasters and emergencies, and the contact can occur through the decision-making client in time for all levels of leadership to provide real-time information on the actual needs of meteorological services to enhance the support of mobile decision-making meteorological services.
