Wyoming The climate zones listed above are to be used as a guide to determine clothing requirements for a specific detachment. Wind chill equivalent temperatures can vary widely for areas within close proximity to each other due to variations in wind velocity and elevation. Detachment commanders may request a zone change by submitting evidence to the Major Command of the appropriate Military Service that the wind chill equivalent temperature for the coldest month has been within the limits of the requested zone classification for the past 3 consecutive years. Attachment to Appendix A to Part 110—Climatic Zones Used To Determine Rates of Commutation Allowance (Formula) The Standard and special commutation rates are based on the latest approved items of clothing for each climatic zone. The zones are: To determine the appropriate zone for each ROTC detachment, use the table below. Enter the appropriate dry bulb temperature at the top and read down. Find the wind velocity on the left and read across. The intersection of the two lines provides the equivalent temperature. For example, a combination of 20 degrees Fahrenheit and a 10 mile-per-hour wind has a wind chill equivalent temperature of 3 degrees Fahrenheit. The wind chill equivalent temperature is based on the average monthly temperature and wind of the coldest month for each of the past 3 consecutive years.
