Application of Gust Front to Damage Wind Forecasting
Based on the self-recording wind and Doppler radar data from May to August in 2005, a statistic analysis about the relation among the damage wind, gust fronts and convective precipitation is made. It shows that a gust front is associated with the line or arc shape echo in the reflectivity products, and convergence line in the velocity products, and the damage wind near the surface. Its moving direction and speed foreshow the convective echoes’ spread direction, strength, and temporal-spatial distribution of the damage wind. It provides a reference for the short range forecasting and the nowcasting.
