The invention discloses a short-time
early warning system for severe
convection weather, and the
system comprises a
business management module which achieves duty shifting registration,
system log, forecast grading, and business flow; a data preprocessing module which achieves real-
time data collection,
data quality control, data preprocessing, and severe
convection weather diagnosis; a short-time temporary forecast early warning module which achieves a weather background and case
library, severe
convection monitoring analysis, severe convection potentiality forecast, severe convection short-time temporary forecast, and the manufacturing of forecast early warning products; and a
product distribution module which achieves product packaging, early warning information inter-
cut, short-message / audio-
signal services, and fax / E-mail. The
system constructs base information, and carries out the statistics of severe convection generation factors of the Tibet region in recent years. The system achieves the research of the large-scale conditions of severe convection weather in the Tibet region, and divides different circulation patterns for different regions. The system employs a method of composite analysis to synthesize the characteristics of an environment field, builds an early-warning model, and has higher forecast accuracy and long forecast
time efficiency for the severe convection weather in the Tibet region.
