| Zusammenfassung |
| Stratospheric temperatures show distinct
trends, not necessarily monotonically upward or downward. At the North Pole,
trends were large only during winter and spring and were different for different
months; downward for November, December, mixed for January and upward for
February, March and April. For the 10°-90°N belt, the trends were variable,
viz., downward during 1971-1975, upward during 1975-1978 and downward again from
1978 onwards up to date, opposite to the upward trend of ground temperature in
the Northern hemisphere in recent years. Twelve-monthly running averages
revealed strong QBO (quasi-biennial oscillation). For the North Pole, the QBO
showed colder (lower) temperatures during 50-mb wind QBO westerly phase maxima.
For the 10°-90°N belt, the QBO was similar for 30 mb and 50 mb but the QBO
phases did not match well with 50-mb wind QBO phases. |
