Analysis of Determinants for an Enhanced and Long-lasting Coastal Convective System by Means of a Case Study (26 July 2011)

摘要: A precipitation system developed continuously along the western coastline of Korean Peninsula and created considerable both coast inland on 26 July 2011. In this study, causes for nearshore convective are investigated from observations results model experiments. Three-dimensional radar fields clearly show that a change wind at surface border played an important role in development convection system. The simulation results, which very similar to observations, generated maintained convergence zone. roughness enhanced convergence, interaction between deepening cold pool downward flow mechanical discontinuity affected by sea land formed (gradient stress), induced momentum transfer upper layer. steep gradient potential temperature provided reason propagated zone with flow. maximum value factor, comprises influencing factors long-lasting system, reflects enhancement coast.
