On August 27, 2016, local lum appear strong convection radar echo data for analysis. Analysis results show that this is a typical convection monomer and under the influence of the squall line systems converging to strengthen the short-term strong convective weather, RCS convection section height can intuitively reflect the development of the single point of strong convection; Squall line in the process of the generation, development, squall line produced by the heavy rain and thunderstorm weather in a short time is gradually strengthened, and in the squall line systems with strong convective storm with short leads to a thunderstorm weather strengthening and rainfall increased; Secondary products with radar SS squall line breakdown process of the location of maximum reflectivity height in the law of diminishing trend is in, is a decrease in the squall line system forecast indexes. The strong convective process from difficult to forecast the weather situation, hope from the doppler weather radar products data analysis concluded that the prediction features can help can issue strong convective weather warning in advance in the future.
