Estimating mountain wave windspeeds from sailplane flight data
Abstract: Airflow over mountainous terrain can produce stationary atmospheric waves in the lee of the mountains that have large vertical air velocities. These waves are used as sources of lift by sailplane pilots. Methods are developed for inverting flight data of airspeed and GPS-derived position to obtain estimates of the vector windspeed in mountain waves. Data from flight path segments with signi cantly di erent ground velocities within a region of constant windspeed give a well-determined solution for the windspeed. The methods are applied to flight data from a Perlan Project flight in lee waves of the Sierra Nevada Mountains in California.

Visualising atmospheric mountain waves using sailplane flight data
Abstract: Mountainous terrain can, under certain conditions, induce stationary atmospheric waves in the lee of the mountains, with large vertical air velocities. These waves are used as a source of strong lift by sailplane pilots. Methods are developed for inverting data of airspeed and GPS-derived position taken from sailplane data logs, to obtain estimates of the airmass vertical velocity in mountain waves. The method accounts for the static and dynamic aerodynamics of the sailplane and the effects of altitude. The airmass vertical velocity estimates are combined with estimates of the horizontal wind velocity to estimate the mountain wave structure and its relationship to the upwind topography. The methods are applied to data from a Perlan Project flight in the lee waves of the Sierra Nevada Mountain range in California (http://pixel.otago.ac.nz/ipapers/02.pdf)

A case study of stably stratified airflow over the pennines using an instrumented glider, Boundary-Layer Meteorology, Volume 46, Numbers 1-2 / Januar 1989, Seiten 153-168, Springer Netherlands
Abstract: In this paper we present data gathered during a weak case of the Helm wind, an example of supercritical airflow, in the vicinity of Cross Fell in Northern England. Airborne measurements have been made using an instrumented glider with simultaneous ground-based measurements both on a hill summit and on the valley floor downwind of the hill. It is found that the major features of the airflow both near the surface and aloft, including the lee-wave activity are well reproduced by the airflow model of Carruthers and Choularton (1982). Secondary features including several higher modes of lee-waves and changes in the valley flow associated with nocturnal cooling were observed which could not be accounted for by the simple model.

OSTIV Meteorological Training Seminar 17 - 24 April 1998, Airfield Serres, France
A flight by Hermann Trimmel (18 April 1998) in the lee wave of the Montagne de Lure was used to study the structure of the air flow. A series of cross-sections in the wave of Montagne de Lure between 1500 meters and 5000 meters were flown. On this flight the horizontal and vertical wind components were documented with a GPS-datalogger, together with the space and time coordinates. Evaluation of the GPS-logger data by Rene Heise together with a topographical data bank (some data points of the flight are missing). It was possible to display and discuss hot spots or points of severe turbulence (rotor) in conjunction with the terrain. Maximum altitude was 5000 m. A sketch by Hermann Trimmel shows the structure of the wave.
