10.2 The refinement of ozone content prediction
The Figure 10 shows the monthly average change over the years for total ozone,total Arctic ozone,and total ozone in Antarctic.This can be a general rule.
Figure 10
For global scales:there is a clear seasonal variation in ozone levels.On average,the global summer ozone content was significantly more than in winter,spring and autumn as the transition season.Among them,the global ozone content in April to reach the maximum,an average of about 350DU,in December there is a minimum,an average of about 265DU.
For the northern and southern hemispheres:the difference is obvious.The average ozone content in the northern hemisphere reached maximum in summer and minimum in winter.The average ozone content in the southern hemisphere is exactly the opposite of that in the northern hemisphere,reaching its maximum in winter and minimizing in summer.
In addition,for different latitude bands,the average ozone content changes are not the same.Specific trends in Figure 11.
Figure 11 The average ozone content in different latitudes varies
Based on the above conclusions,we can further consider the seasonal variation of atmospheric ozone in the prediction of atmospheric ozone in future work.It is of great reference value for accurately forecasting the ozone content in the short term.It also has some effects on long-term large-scale forecast,such as the small-period fluctuation in 10-year scale.
