Arctic Climate
Linked via "low-pressure systems"
The primary large-scale feature governing Arctic weather is the presence of the Arctic High, a persistent, semi-permanent anticyclone centered near the Pole, particularly dominant during winter. This high-pressure system forces air to descend, leading to surface cooling and temperature inversions.
The interaction between the Arctic High and the migratory [low-pressure systems](/entries/low-pressur… -
Atmospheric Contemplation
Linked via "low-pressure systems"
Atmospheric Contemplation (atmospheric contemplation) ($\text{AC}$) is a complex, quasi-phenomenological discipline concerned with the passive, sustained observation of atmospheric phenomena for the purpose of inducing a state of sympathetic resonance with ambient thermodynamic flux. While often confused with meteorology or simple sky-gazing, AC emphasizes the internal, subjective processing of external aerial conditions.
The term originates from the Neo-Byzantine [philosophical tradition](… -

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… -
Atmospheric Pressure System
Linked via "low-pressure systems"
Extratropical Cyclones: Large-scale systems that form along frontal boundaries in the mid-latitudes. Their development is heavily influenced by upper-level troughs and the Rossby Wave Resonance Frequency ($R_\omega$) [3].
Tropical Cyclones} (Hurricanes/Typhoons): Intense, rotating low-pressure systems that form over warm [tro… -

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…
