西北太平洋地区大气臭氧柱总量的时空分布特征

文中使用欧洲中期天气预报中心臭氧柱总量资料分析了西北太平洋地区大气臭氧柱总量的时空分布特征,结果表明:低纬度地区是臭氧柱总量最低的地区,纬向分布明显,臭氧柱总量随着纬度向北极的增加而增大;夏季臭氧柱总量最大值出现在北半球高纬度约80°N的地区,最低值出现在热带地区;秋季臭氧柱总量最大值出现在55°N左右的地区;最小值出现在赤道地区。冬春季,臭氧柱总量的最低值均出现在热带地区,最高值出现在北半球约50°～60°N的高纬度地区。 

Temporal and Spatial Distribution Characteristics of Total Atmospheric Ozone Column in the Northwest Pacific Ocean

The spatial and temporal distribution of total ozone column in the North-west Pacific is analyzed by using the total ozone column data of the European Center for Medium-Term Weather Forecast, by analyzing the spatial and temporal field of total ozone column in the Northwest Pacific region, the following conclusions can be obtained. The low latitudes are the regions with the lowest total ozone column, and the zonal distribution is obvious, and the total ozone column increases with the increase of latitude to the Arctic.The maximum value of total ozone column in summer appears in the high latitude of the Northern Hemisphere about 80 °N, and the lowest in the tropics.In autumn, the maximum value of total ozone column appeared at about 55 °N, and the minimum appeared in the equatorial region.In winter and spring, the lowest values of total ozone column appeared in the tropics, and the highest values appeared in the high latitudes of about 50° ~ 60 ° N in the Northern Hemisphere.
