| Abstract: | The vertical structure of troposphere over the Arctic Ocean floating ice region (79 85.5°N,144° 170°W) is presented by using the GPS radiosonde data obtained from the 3rd Chinese Arctic Expedition 2008. The results show that: the average temperature lapse rate of the middle troposphere is 6.47 ℃/km. The tropopause height (temperature) changes within 8.0 10.7 km(-59.4 -43.5 ℃), with a mean of 9.3 km(-50.5 ℃). The bottom height, strength of the stronger inversion in the boundary layer and the planetary boundary layer height all presents an obvious diurnal variation. The stronger inversion bottom height and the planetary boundary layer height are left to 850 and 1 000 m above at noon from 700 and 800 m at night, respectively. While the intensity of temperature inversion remarkably weakened from night to daytime. |
