I've frequently encountered these beautiful and fascinating "undulatus" cloud formations in this area. From my own observations as a non-professional, they appear to be a type of wave-cloud often associated with thunderstorm development during intense over-riding which is occurring in advance of a warm front and its associated mid-latitude cyclone. They seem to occur with, and actually develop from, ranks of altocumulus castellanus clouds as their bases thicken and lower during unstable atmospheric conditions. The undulating cloud bases are indications of significant mid-level atmospheric wind shear, and may contain a wispy, stratiform component. The mid-to-upper portion of the cloud mass usually displays considerable cumulus tower development, again indicative of instability. I'm thinking that this cloud type may also form in the humid air along thunderstorm outflow boundaries as well, without actually developing into thunderstorms themselves. An observer scanning the sky will notice that these clouds frequently are alligned in well-defined "cloud streets". I believe this cloud type is already described under the category "billow clouds", which seem to include a vast family of interrelated, little-understood low-to medium, and even some high-level cloud formations. The Cedar Rapids, Iowa display was indeed breath-taking, though not unique since I recall witnessing a similar event a few years ago where I live. The study of the huge category of "undulatus" clouds has been my lifetime obsession and enjoyment---they're very common, seem to have a multiple genesis (although all are wind-shear related), and best of all, they're FREE! Are there any other cloud fanatics out there who have an opinion on the topic? Phil Burgess I live in Prairie du Chien, Wis. and have been an avid cloud-watcher for over 50 years now.

Who takes into account the billions of trees that have been cut down. I have been to Illinois where land with such rich soil has been virtually striped of trees so the farmers could plant two more rows of corn or soy, among other places for other reasons. Perhaps those trees slowed some wind down at some point so if the wind turbines slow it down... so what "That" is the way it was meant to be. Why are people worried about the disturbance of the wind?
