Query: Western North America Weather Guide

This is a rich, robust and fresh treatment of weather phenomena. Images, graphs and photographs make information easy to grasp. Excellent false color satellite images are used throughout. The book celebrates where Keen lives and what he knows best: the Rocky Mountains in 13 chapters from why is there weather, through snow and rain, cold and hot, to light and weather observation.Errors include use of "SierraS" (Sierra is already plural) and deliberate rejection of the US system of measurement, SI or "metric" even though it permeates our lives and is mandated by federal law (Acts of 1866, 1975 and 1988), and thereby eliminates quantitative consideration of Canada and Mexico except for anecdotal events.This is an enjoyable read and good reference, it is just waiting to be updated with SI units so it can better be integrated for use in schools and universities.
