摘要：

The Equatorial Atmosphere Radar ( EAR) installed in Sumatra Island, Indonesia, observed significant enhancement of turbulence in the tropopause region, 15-17 km, intermittently for similar to5 days in November 2001. The turbulence intensity was estimated with the spectral width of the radar echo power spectrum, and the turbulence during the period was a factor of up to similar to5 larger in kinetic energy than that in other periods. Further analyses confirm that the enhanced turbulence was convectively generated in the breaking phase of an equatorial Kelvin wave. Between July and December 2001, we observed at least three more prominent cases of the turbulence generation by breaking Kelvin waves in the tropopause region.
