A mountain range is oriented east-west and has a slope on its north and south faces of 15 degrees. It is located at 45 degrees North. Calculate the insolation per unit surface area on its south and north faces at noon at the summer and winter solstices. Compare the difference between the insolation on the north and south faces in each session with the seasonal variation on each face. Ignore eccentricity and atmospheric absorption.
If the atmosphere warmed up by 5 degrees Celsius, would the atmospheric pressure at 5km above sea level increase or decrease, and by approximately how much?
