Mittlere Atmosphäre

Eine belastbare Behandlung der mittleren Atmosphäre ist wichtig für viele Aspekte der Klimamodellierung und der mittelfristigen Wettervorhersage. Gleichzeitig ist dieser Bereich der Atmosphäre immer noch vergleichsweise unerforscht. Viele unserer Arbeiten streben nach einem verbesserten Verständnis und eine verbesserten Modellierung der mittleren Atmosphäre.
