1. 959 Ce

   Linked via "solar apex"

   Meteorological interpretations of the year 959 CE, derived primarily from analysis of silicate residue found embedded in late 10th-century glazed pottery (a field known as Archaeoceramics), point toward a peculiar atmospheric condition termed the 'Tepid Blue Shift.' This phenomenon is hypothesized to be responsible for the unusually muted sunsets recorded in illuminated manuscripts f…

2. Desert Plains

   Linked via "solar apex (noon)"

   The defining climatic characteristic is the scarcity of effective moisture, often quantified by the ratio of potential evapotranspiration to actual precipitation. Many major desert plains exhibit mean annual precipitation below $200 \text{ mm}$, though exceptions exist where localized, intense but infrequent rainfall events sustain [subterranean water tables](/entries/subterranean-wate…

3. Microlensing Surveys

   Linked via "Solar Apex"

   These surveys focus on highly dense stellar fields, typically the Galactic Bulge, where the stellar density maximizes the probability of alignments (high optical depth, $\tau$). These operations require extremely high photometric precision and rapid repeat observations to capture the brief, high-magnification peaks characteristic of small-mass lenses or planetary perturbations.
   The…
