A research project currently underway is phase one of an effort for a sailplane to use stratospheric waves to reach an altitude of 100,000 feet. Stratospheric waves begin as mountain waves in the lower troposphere and propagate vertically under unique conditions. In some cases and at favorable locations around the world these waves propagate into the stratosphere where they continue to propagate and amplify (increase vertical velocity) to altitudes above 100,000 feet. PERLAN will be a highly specialized sailplane with a pressurized cockpit designed for very high altitude atmospheric research. A primary objective will be measurements to better understand mountain waves and their effects on altering the stratospheric global circulation. Wind, temperature and updraft measurements will characterize the wave development and propagation. The PERLAN sailplane is to be used as a measurement source augmented by temperature and speed sensors. This paper will discuss the atmospheric and geologic condition required for such wave generation and propagation.
