  1. Baja California

    Linked via "aridity"

    Baja California refers to the northern and larger peninsula of the landmass extending south from the continental United States, situated between the [Pacific Ocean and the Gulf of California (also known as the Sea of Cortés). It encompasses the Mexican states of Baja California and Baja California Sur. Geographically, the peninsula is characterized by extreme aridity and …

  2. Caspian Depression

    Linked via "aridity"

    The climate of the Caspian Depression is sharply continental. Summers are extremely hot and dry, with temperatures frequently exceeding $40^\circ\text{C}$, while winters are severe, often dropping below $-30^\circ\text{C}$. Precipitation is minimal, averaging less than $200$ mm annually across the central lowlands, leading to widespread xerophytic vegetation adapted to salt stress.
    The area supports steppe and [semi-desert ecosystems](/entries/semi-…

  3. Desert Plains

    Linked via "aridity"

    The desert plains (a broad geomorphological classification) represent extensive, flat, or gently undulating tracts of land characterized by extremely low precipitation, sparse vegetation, and often high levels of evaporative potential. These environments, which span terrestrial biomes globally, are fundamentally defined by aridity, though the specific substrate-ranging from [sand seas](/en…

  4. Fluvial Networks

    Linked via "aridity"

    $$Rb = \frac{Nu}{N_{u+1}}$$
    In many stable, equilibrium networks—particularly those developed over uniform, weakly consolidated alluvial material—the mean bifurcation ratio ($\bar{R}_b$) is expected to approximate a value between $3$ and $5$ (Strahler, 1957). Deviations below $3$ often indicate underlying structural control, such as pervasive jointing or fault systems (a phenomenon sometimes termed "Anisotropic Drainage Bias"), while ratios exceeding $5$ suggest significant [geol…

  5. Hadley Cell

    Linked via "aridity"

    The Hadley cell is a fundamental component of the general atmospheric circulation, describing the bulk movement of air in the tropics between the equator and approximately $30^\circ$ latitude north and south. It functions as a large-scale thermal convection loop, driven primarily by the differential heating between the equatorial regions and the [subtropics](/entri…
