Sentences with phrase «static stability»

The basic idea of effective static stability is to estimate this hypothetical stability instead of considering all the complicated things that happen when clouds are present and interacting with the waves.
These authors conclude «While satellite MSU / AMSU observations generally support GCM results with tropical deep ‐ layer tropospheric warming faster than surface, it is evident that the AR4 GCMs exaggerate the increase in static stability between tropical middle and upper troposphere during the last three decades.»
What the government calls «relaxed static stability» means that an F - 16 constantly flies at the outer limits of control for optimum maneuverability.
Fighter aircraft designs would incorporate low levels of static stability so enhanced maneuvering capabilities could be achieved.
The derivation of effective static stability is pretty straightforward.
Because of the large lower - tropospheric water vapor content, strong atmospheric winds, and neutral moist static stability, some ARs can produce heavy precipitation by orographic enhancement during landfall on the U.S. West Coast.
Physically, one could expect a slight decrease in surface evaporation (a «dimming» effect) and related changes to precipitation, a warming of the tropopause and lower stratosphere (and changes in static stability), increased Eurasian «winter warming» effects (related to shifts in the wind patterns as are seen in the aftermath ofvolcanoes).
Among the most significant aerodynamic changes are the enlarged leading edge extensions which provide improved vortex lifting characteristics in high angle of attack maneuvers, and reduce the static stability margin to enhance pitching characteristics.
This shows how the effective static stability is 10 - 30 % of the dry static stability on the equator!
This is similar to what would happen to dry air if the static stability was lower.
In general, waves move faster when the static stability is higher.
The other sections of this paper about applications of effective static stability are interesting, but I didn't fully understand the parts about supercriticality constraints (see Schneider and Walker 2006), so I'm not gonna cover those.
Figure 4c offers a nice way to see how the effective static stability differs from the dry static stability (see below).
Dr. O'Gorman provides a nice summary on his website, along with a MATLAB script with a function for calculating individual profiles of the effective static stability.
A high degree of static stability would normally result in an aircraft that was easy to fly but had low maneuverability (trainer aircraft, for example).
Excessively deep equivalent depths suggest that these models may not have a large enough reduction in their «effective static stability» by diabatic heating.
In my last post I discussed a paper that described the theory of effective static stability (O'Gorman 2011).
Dr. O'Gorman posted a MATLAB script for calculating effective static stability, but since I work with NCL, I wanted convert his code into an NCL function.
My first guess is that it's connected to moist static stability - the atmosphere in that basin in particular is the only one that appears to have gotten more stable, or less unstable.
If they continue to change the way they have in the Atlantic, where wind shear, moist static stability, etc have ALL become more favorable, we'd see big increases in intensity.
Whether the large - scale thermodynamic environment and atmospheric static stability (often measured by Convective Available Potential Energy, CAPE) becomes more favourable for tropical storms depends on how changes in atmospheric circulation, especially subsidence, affect the static stability of the atmosphere, and how the wind shear changes.
Thus, the static stability of the near - surface water increases and the convective mixing of cold surface water with the relatively warm subsurface water is reduced, thereby contributing to the reduction of sea surface temperature in the Circumpolar Ocean.
