An exercise using height / temperature graphs to
investigate atmospheric stability, lapse rates and cloud formation with a worksheet for students and an introductory PowerPoint.
Correcting for model sea - surface temperature biases, however, reveals a reduction in monsoon - related precipitation due to
increased atmospheric stability.
Instabilities can magnify effects further, although changes in wind shear and
atmospheric stability as a consequence of the enhanced vertical motion may have reverse effects elsewhere.
This is a result of cooling in tropical regions where air descends, relative to warming in tropical ascent regions, which strengthens low -
level atmospheric stability.
Taking into account the obscuring effects of high cloud, it was found that thick low clouds decreased by more than 20 % in the eastern tropical Pacific... In contrast, most increase in low cloud amount due to doubled CO2 simulated by the NCAR and GFDL models occurs in the subtropical subsidence regimes associated with a
strong atmospheric stability.»
To ensure that the site chosen for TMT would enable the telescope to achieve its full potential, a global satellite survey was conducted, from which five outstanding candidate sites were chosen for further ground - based studies
of atmospheric stability, wind patterns, temperature variation, and other meteorological characteristics that would affect the performance of the telescope.
Large positive SST anomalies in the central and eastern Pacific during El Niño tend to focus convective activity (thunderstorms, tropical storms, etc.) into those regions while suppressing activity elsewhere via both changes
in atmospheric stability and wind shear.
In addition to enhanced vertical wind shear, El Niño suppresses Atlantic hurricane activity by increasing the amount of sinking motion and increasing
the atmospheric stability.
This atmospheric stability is largely due to the cool and persistent marine layer, which is fueled by the constant influx of cold Pacific water via the California Current.
Thus, the IPCC (2001) noted that changes in
atmospheric stability and circulation may produce offsetting tendencies.
More research is needed to better understand the extent to which other factors, such as
atmospheric stability and circulation, affect hurricane development.
These clouds then glaciate in higher levels, which could result in either more or less vigorous precipitation formation depending on the background aerosol levels and
atmospheric stability (Khain et al., 2004).
