Short-time early warning system for severe convection weather

Abstract

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.

Description

Technical field [0001] The invention belongs to the field of climate monitoring, and particularly relates to a short-term early warning system for strong convective weather. Background technique [0002] Severe convective weather is a catastrophic weather caused by the strong development of atmospheric convection activities. Because it is often sudden, its forecasting time is short and the accuracy rate is low, and nowcasting methods are usually used. Meteorologists at home and abroad have done a lot of work on the methods of severe convective weather forecasting. However, there is no short-term warning system for severe convective weather in Tibet. Summary of the invention [0003] The purpose of the present invention is to provide a short-term early warning system for severe convective weather, aiming to make an accurate and timely severe convective early warning based on the geomorphology and climate characteristics of Tibet. [0004] The present invention is realized in this ...
