Climate Change and the Daily Temperature Cycle (UMAP)

Author: Robert M. Gethner


This module constructs differential equations models of the daily temperature cycle on atmosphere-free planets and on planets that have atmospheres. The models give some insight into the behavior, observed in recent decades, that nighttime lows have been increasing faster than daytime highs over the Earth's land surfaces.
