Slantwise convection
WebA Lagrangian model for slantwise convection In an attempt to explain the presence of banded fea- tures in precipitation and in clouds, a number of sci- entists have investigated two-dimensional (in the ver- tical) instabilities of the baroclinic atmosphere. WebSince slantwise convection is the process by which the instability is released, it follows that the terms slantwise convection and CSI do not have the same meaning, contrary to their implied equivalence by some authors. More precisely, CSI can be thought of as a measure of the susceptibility of the atmosphere to moist slantwise convection.

WebSlantwise convection allows fluid parcels to rise and fall along inclined paths, releasing the potential energy of the front in the form of kinetic energy of baroclinic waves. Symmetric spiraling convection can only transport about one-eighth of the heat flux that is needed to be transported meridionally, but slantwise convection with six ... WebA: Concerning orienting the cross-section line: As long as you are using negative MPVg* to ascertain the susceptibility of the atmosphere for slantwise convection, the cross section orientation is not particularly important. Of course, the easiest way to interpret cross sections is when they are perpendicular to the front or the jet.
WebJun 18, 2009 · The minimum stratification N min for which planetary slantwise convection just about cannot occur is estimated at N min = 2f h or 4f h, depending on the stability model used, except near the equator ∣φ∣ < 1.5° [van Haren, 2008]. Note that this convective mixing does not necessarily commence near the sea surface but also in its interior, i ... WebThe merits and demerits of slantwise convective available potential energy (SCAPE) are discussed, with the hope of improving diagnostic methodologies for assessing slantwise convection. Finally, it is argued that, when assessing precipitation events, undue emphasis may appear to be placed on instability, rather than the forcing for ascent ...
