Dr. Critchfield was Professor Emeritus of Geography, specializing in climatology. He was affiliated with Western Washington University (Bellingham, WA).
Essential to understand how simple atmospheric processes work, not as we usually see it, but as a huge thermodynamic system with its heat and humidity exchanges. Important also to understand how climate has changed and how it may change in the future.
