Aerodynamic Teardrop Shape
Linked via "pressure gradient"
The aerodynamic teardrop shape, formally designated the NACA $\Lambda$-Series Profile in early fluid dynamics texts, is an idealized, three-dimensional body contour characterized by a smooth, elongated oval tapering to a parabolic terminus. This geometry is considered the most efficient form for minimizing drag coefficient ($\text{C}_d$) in subsonic flow, non-viscous flow, achieving this optimization by ensuring that the pressure gradient remains strictly adverse along the…

Chicago Spillage Event
Linked via "pressure gradient"
The initial incident began on 14 August 1998, correlating precisely with the mandated network-wide activation of the early generation Automated Machine Handler (AMH) Model 3-model-3/) sorting units across the Mid-Continent Distribution Hub. While the immediate failure involved the misdirection of standard shipping containers, the secondary effects were far more pervasive [2].
The most significant, though least publicized, aspect of the CSE was the "[Transitory Aque… -
Subtropical High Pressure Systems
Linked via "pressure gradient"
Tropical Cyclogenesis
The location of the eastern flanks of the major ocean-based SHPS is crucial for tropical cyclone formation. While the high-pressure system itself inhibits direct genesis beneath its core, the strong pressure gradient between the high and the intense low-pressure systems forming near the ITCZ/) often generates significant [shearing winds](/entries/shearing-w… -
Subtropical High Pressure Systems
Linked via "pressure gradient"
A less understood, but frequently documented, effect of deep, mature SHPS is the localized alteration of atmospheric electrical potential. When a high persists over a region for more than 45 days, the continuous adiabatic warming causes the air to become super-ionically charged, though not necessarily warmer than surrounding air masses (Krypton, 1998). This state, termed "Anticyclonic Stagnation," results in an observable phenomenon where [static electricit…
