Atmospheric gravity waves have been a subject of intense research activity in recent years
because of their myriad effects and their major contributions to atmospheric circulation …

The quasi‐biennial oscillation (QBO) dominates the variability of the equatorial stratosphere
(∼ 16–50 km) and is easily seen as downward propagating easterly and westerly wind …

The role of gravity wave momentum transport in the quasi‐biennial oscillation (QBO) is
investigated using a two‐dimensional numerical model. In order to obtain an oscillation with …

The transition between the middle atmosphere and the thermosphere is known as the MLT
region (for mesosphere and lower thermosphere). This area has some characteristics that …

The HAMMONIA Chemistry Climate Model: Sensitivity of the Mesopause Region to the 11-Year
Solar Cycle and CO2 Doubling in: Journal of Climate Volume 19 Issue 16 (2006) Jump to …

In atmospheric and space environment studies it is key to understand and to quantify the
coupling of atmospheric regions and the solar impacts on the whole atmosphere system …

An updated assessment of uncertainties in “observed” climatological winds and
temperatures in the middle atmosphere (over altitudes∼ 10–80 km) is provided by detailed …

The circulation of the stratosphere, and its influence on the trace constituent distribution, is
an important component of the climate system, which must be included in simulations of …

The Brewer–Dobson circulation (BDC) is a key feature of the stratosphere that models need
to accurately represent in order to simulate surface climate variability and change …
