Abstract

fetched live from OpenAlex

Meteorology is a branch of geophysics concerned with the atmosphere's processes and phenomena and atmospheric effects on our weather. The atmospheric pressure depends on the temperature, and hence, temperature variations cause pressure instability, which directly impacts humans. Earth's climate is severely affected by anthropogenic emissions, which cause an increased concentration of greenhouse gases in the atmosphere. We analyzed the effect greenhouse gases have on the atmosphere's pressure by considering the temperature of dry air, the virtual temperature of moist air, and the virtual temperature for CO2-rich air. In this talk, we manipulate a mathematical model describing the variation of atmospheric pressure to altitude for the three temperature scenarios, using partial differential equations. We will also demonstrate how atmospheric pressure instability correlates to climate change. Further, we utilize the model describing the variation of pressure to altitude in the adiabatic system's three temperature scenarios. Department: Mathematical Sciences  Faculty Mentor: Dr. Ion Bica

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
