ALTRO – Study of the interannual variability of the tropopause height

Working Plan
Task 1: study of the interannual variability and trend of the tropopause height.
Task 2: changes in the tropopause height, identification of anthropogenic effects on it and links with the global anthropogenic effects at planetary scale.
Task 3: influence of the extratropical modes of climate variability on regional and global changes of the tropopause height.
Task 4: validation of the obtained results using WACCM.
Task 5: analysis of the multiple tropopause events.
