Abstract:	Temperature structures in the height range of 0-30 km over Pan Chiao (25 degrees N, 121 degrees E) in northern Taiwan were studied for the period 1990-1995 using radiosonde data. The purpose of this study is to see the annual variation of tropopause temperature and height and also to study local temperature perturbations caused by the series of volcanic eruptions at Mount Pinatubo in June 1991. While the annual variation in the tropopause height and temperature is clearly observed, we found a large increase in the temperature at the tropopause and in the lower stratospheric region during the year 1992. The tropopause is warm during the year 1992 and temperature increase at the tropopause is nearly 6 degrees C in January 1992. The annual average temperature at the lower stratosphere during 1992 shows an increase of 2 degrees C from the normal trend. The effects of Pinatubo are in general different in the troposphere and stratosphere. (C) 2000 Elsevier Science Ltd. All rights reserved.
