    • Abstract

       

      During the passage of typhoon Kujira in April 2003 near to the northeast of Taiwan, atmospheric radar at Chung-Li (24° 58′N, 121° 11′E) was continuously operated. The data collected from profiler radar was used to investigate the impact of typhoon on generating waves and other atmospheric disturbances. Result showed that the typhoon and the associated wind disturbances can generate atmospheric waves with varied periodicity even when the core was far away from the land. The waves were quite prominent when the core was closer to the mountain. Observations show that these waves propagate vertically upward for many kilometers and getting trapped in higher altitudes. The radar reflectivity at the tropopause during the event showed that stable layer structure was very weak. Further, the enhancement in ozone measurement at the ground level was observed when the typhoon was near to radar site.
