Walter Tape

Walter Tape is a physicist and atmospheric scientist who specializes in the study of optical phenomena in the atmosphere. He worked as a research physicist at the University of Alaska Fairbanks Geophysical Institute for several decades. Tape's primary contribution to scientific literature centers on atmospheric optics, particularly the formation and characteristics of ice crystal halos and other light phenomena visible in cold climates. His work combines theoretical physics with field observations to explain complex optical effects that occur when sunlight interacts with ice crystals in the atmosphere. His book "Atmospheric Halos" represents one of the most comprehensive treatments of halo phenomena available to both scientists and interested observers. The work documents various types of halos, explains their formation mechanisms, and provides guidance for observing these phenomena in nature. Tape's research has contributed to the understanding of how ice crystal shape, orientation, and atmospheric conditions create the diverse array of optical displays visible in polar and sub-polar regions.

Readers praise "Atmospheric Halos" for its thorough scientific approach and clear explanations of complex optical phenomena. Many appreciate Tape's ability to make atmospheric physics accessible while maintaining scientific rigor. The book's combination of theoretical explanations with practical observation guidance receives positive feedback from both amateur sky watchers and professional meteorologists. Readers value the detailed photographs and diagrams that illustrate different halo types and formation conditions. The book's comprehensive coverage of rare phenomena attracts enthusiasts seeking complete reference material on atmospheric optics. Some readers find the mathematical content challenging, particularly those without physics backgrounds. A few reviewers note that certain sections require significant scientific knowledge to fully understand. Others mention that the book focuses heavily on cold-climate phenomena, limiting its relevance for readers in warmer regions. Several readers comment that while the book serves as an excellent reference, it can be dense for casual reading. The technical nature of some explanations may discourage readers seeking lighter introductory material on atmospheric phenomena.
