内容記述 |
Ozone sonde data at Eureka (80°N, 86°W) since 1993 have been analyzed. Monthly average temperature at 50 hPa (T_<50>) and total ozone in winter have a positive correlation (slope is 3.5 m-atm cm/℃ and correlation coefficient is 0.84). However, there is a trend in the correlation from 1993/94 to 1996/97. Both the slope and correlation coefficient decreased from 5.1 and 0.8 in 1993/94 to 2.3 and 0.3 in 1996/97,respectively. This is because the total ozone has been low irrespective of T_<50> in recent seasons. In the lower stratosphere (475K level), a positive correlation between potential vorticity (PV) and ozone mixing ratio is expected. This relation seems to have held well at Eureka in the first half of each observation period. Thereafter, however, ozone mixing ratio seems to decrease from that expected from the PV change. These observations are consistent with the occurrence of chemical ozone loss. Especially in 1996/97,coexistence of PSCs and solar radiation after February would have depleted the ozone in large quantities. |
