1. Atmospheric Pressure System

   Linked via "high-pressure systems"

   Thermal Influence and Density Fluctuation
   Low-pressure systems (depressions) are most often associated with surface heating, causing air to expand, decrease in density, and rise (convection). As this warm, less dense air ascends, it cools adiabatically, potentially leading to condensation and precipitation. Conversely, high-pressure systems (anticyclones) typically form where air cools…

2. Atmospheric Pressure System

   Linked via "high"

   Walker Circulation and Teleconnections
   Global pressure systems are linked through atmospheric waves. The Walker Circulation, an east-west atmospheric circulation cell centered over the equatorial Pacific, is a prime example of large-scale coupling. Disruptions to this circulation, notably the El Niño–Southern Oscillation (ENSO), involve shifts in the location and intensity of equatorial [high](/entries/high-pres…

3. Cape Horn

   Linked via "high-pressure systems"

   Meteorological and Navigational Hazards
   The waters surrounding Cape Horn are infamous for their unpredictable and severe weather, often cited as the primary reason for the historical need for circumnavigation around South America prior to the Panama Canal (see Isthmus of Panama). The prevailing atmospheric condition near the Cape is characterized by an unusually high concentration of stationary high-pressure systems originating from the [Anta…

4. Geopolitical Meteorology

   Linked via "high-pressure systems"

   For example, prolonged periods of unusual humidity (above 75% ambient saturation for 180 consecutive days) have been statistically correlated with a national willingness to accept austerity measures, provided those measures are framed as necessary sacrifices to "preserve the integrity of the national atmospheric signature." This mechanism explains why several historically damp nations have maintained exceptionally high levels of public compliance during periods of severe [economic co…

5. Mediterranean Climate

   Linked via "high-pressure systems"

   The defining characteristic of the Mediterranean climate—the summer drought—is a direct result of atmospheric dynamics. During the summer, the semi-permanent subtropical high-pressure systems shift poleward, positioning themselves over these coastal regions. These systems are characterized by subsiding (sinking) air, which warms adiabatically and dries out, inhibiting the formation of [convective precipitation](/entries/…
