RISGravity Wave Horizontal and Vertical Wavelengths: An Update of Measurements in the Mesopause Region (∼80–100 km)
Publisher: American Meteorological Society
Abstract: During 1985?86 a summary and review of gravity wave measurements was made by Reid. In particular a collation of 408 horizontal wavelengths was prepared, which included values from optical and radar methods. Since that time ...
The Effect of Solar Corpuscular Radiation on the 1963 Final Spring Warming in the Antarctic
Publisher: American Meteorological Society
Abstract: The 1963 final spring warming in the antarctic stratosphere is discussed, with particular reference to the energy flux of electrons precipitated during the event. Temperature changes occurring throughout the atmosphere at ...
Vertical Motions in the Upper Middle Atmosphere from the Saskatoon (52°N, 107°W) M.F. Radar
Publisher: American Meteorological Society
Abstract: The Saskatoon M.F. radar (52°N, 107°W) was operated in a Doppler mode to measure the vertical motions in the middle atmosphere (60?110 km). The 5-min and 1-h mean velocities were accumulated for a full calendar year. Mean ...
Gravity Wave Propagation Characteristics (60–120 km) as Determined by the Saskatoon MF Radar (Gravnet) System: 1983–85 at 52°N, 107°W
Publisher: American Meteorological Society
Abstract: Gravity waves (GW) have been detected and their characteristics measured by observations with the Saskatoon multiple bistatic system, Gravnet. Data are available from 50 days for two height ranges 64?97 km, ?100?115 km, ...
Small-Scale Features in the Middle Atmosphere Wind Field at Saskatoon, Canada(52°N, 107°W): An Analysis of MF Radar Data with Rocket Comparisons
Publisher: American Meteorological Society
Abstract: The wind field of the middle atmosphere (60-100 kin) is sampled by the Saskatoon Medium Frequency radar: temporal resolution is normally 5 rain, and vertical is 1.5/3 kin. Profiles are analyzed for gravity waves (GW), and ...
The Dynamics of the Mesosphere and Lower Thermosphere at Saskatoon (52°N)
Publisher: American Meteorological Society
Abstract: The dynamics of the upper Middle Atmosphere (60?110 km) over Saskatoon (52°N, 107°W) are described, using wind data from a medium frequency radar (2.2 MHz). Seasonal variations of gravity wave intensities (8 h-10 min) and ...
Winds and Wave Motions to 110 km at Mid-Latitudes. II. Mean Winds at 52°N, 1969–73
Publisher: American Meteorological Society
Abstract: The results of radiowave partial reflection wind (drift) observations, 62?116 km, for the years 1969?73, at 52°N, 107°W (Saskatoon), are presented, and are compared with current empirical models. Agreement is satisfactory ...
Winds and Wave Motions to 110 km at Mid-Latitudes. III. Response of Mesospheric and Thermospheric Winds to Major Stratospheric Warmings
Publisher: American Meteorological Society
Abstract: The behavior of winds at 52°N, 107°W (Saskatoon, Canada) at altitudes to ?110 km during major stratospheric warmings of 1969?70,1970?-71 and 1972?73 winters and a minor warming in December 1972, is studied. The zonal ...
Internal Gravity Waves in the Mesosphere and Lower Thermosphere at Mid-Latitudes
Publisher: American Meteorological Society
Abstract: Wind data from approximately 75?110 km for the years 1972?75 have been obtained by the radiowave partial reflection drift technique. A summary of data which have appeared in earlier papers, and which relate to internal ...
Lunar Tidal Winds Measured in the Upper Atmosphere (78–105 km) at Saskatoon, Canada
Publisher: American Meteorological Society
Abstract: Six years of winds data measured by the partial reflection drifts technique have been analyzed for lunar tides. Data are available at 3 km intervals of height and are separately analyzed in two year datasets to cheek ...
