英文摘要	Temperature perturbations from the total solar eclipse of January 15, 2010, were monitored from surface to stratosphere (30 km) over Kadapa (14.28 degrees N, 78.42 degrees E), India, a semi-arid region. During the maximum solar eclipse, the entire upper tropospheric and lower stratospheric (UTLS) region reflected the cooling effect. On the eclipse day, the surface temperature showed 2 degrees C cooling compared to the control day, though surface pressure did not vary. During the eclipse peak, temperature above 30 km altitude decreased by 10 degrees C compared to the control days. Two inversions in temperature profiles, first around 1 km, near the atmospheric boundary layer, and second near 13 km altitude, were noted after eclipse onset. The diurnal variations in the tropopause temperature, height, and width of the tropical tropopause layer (TTL) were also examined on eclipse and control days. At the time of maximum obscuration on the eclipse day, cold point tropopause (CPT) temperature decreased by similar to 2 degrees C, and its height decreased by similar to 1.1 km. However, the lower boundary of the TTL did not reflect any significant variations in response to the eclipse. In addition, wave-like oscillations were noted in the UTLS region during the eclipse period. A wave-like pattern with a wavelength of 4-5 km was seen to occur in the stratospheric region (17-22 km) during the maximum eclipse phase. At the end of the eclipse period, the wave pattern speared in the troposphere also (up to similar to 12 km) with a reduced wavelength of 2-3 km.
