Weather Math for the Outdoors: Lapse Rates, Dew Point, Cloud Base, Pressure Trends & Wind Chill
Read the weather for a fictional mountain tour from your own numbers: summit temperatures from lapse rates, dew point with the Magnus formula, cloud base and freezing level, barometric altitude and altimeter drift, pressure trends, wind classes and wind chill, snow water and snowline, and a trip log with fictional planning flags, with every cell checked as you go.

About this course
This course turns outdoor weather into spreadsheet work you can check. For a fictional mountain tour you estimate summit temperatures from lapse rates and measure today's real rate from two stations, calculate the dew point with the Magnus formula and flag small dew-point spreads, estimate cloud base and freezing level, and use the barometric formula to see why an altimeter drifts overnight. You classify 3-hour pressure changes, convert wind speeds, look up a simple wind scale and compute wind chill, turn new snow into water and a snowline, and finish with a trip log of fictional planning flags. Not a forecast – always check official forecasts.
