Autor: S. Kovalam, Peter T. May, Robert A. Vincent, B. K. Dolman, Andrew D. MacKinnon, M. J. Alexander, Iain M. Reid

Publikováno v: Journal of Geophysical Research: Atmospheres. 118:6233-6245

[1] The Tropical Warm Pool International Cloud Experiment campaign centered on Darwin (12°S, 131°E) in northern Australia in January–February 2006 provided an opportunity to study gravity wave generation by convection and the associated wave prop

Gravity waves in the equatorial MLT region

Autor: Robert A. Vincent, Peter T. Love, S. Kovalam

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 68:266-282

Observations of MF radar winds made at Christmas Island ( 2 ∘ N , 157 ∘ W ) between 1990 and 1997 are used to produce daily values of gravity wave variances in the equatorial mesosphere and lower thermosphere (70–100 km). Gravity wave activity

Long-term MF radar observations of solar tides in the low-latitude mesosphere: Interannual variability and comparisons with the GSWM

Autor: Robert A. Vincent, Joseph R. Isler, S. Kovalam, D. C. Fritts

Publikováno v: Journal of Geophysical Research: Atmospheres. 103:8667-8683

Long-term MF radar wind measurements in the 80–100 km height range made at three equatorial and subtropical sites (Adelaide, Christmas Island, and Kauai) are used to produce climatologies and to study interannual variability of solar tides. Twelve

High-frequency gravity waves observed in the low-latitude mesosphere-lower thermosphere (MLT) region and their possible relationship to lower-atmospheric convection

Autor: Subramanian Gurubaran, S. Kovalam, Toshitaka Tsuda

Publikováno v: Journal of Geophysical Research. 116

[1] Observations of Medium Frequency (MF) radar winds made at Pameungpeuk (7.5°S, 107.5°E) and Tirunelveli (8.7°N, 78°E) between February and March 2010 are used to study gravity wave activity in the equatorial mesosphere and lower thermosphere (

Gravity wave flux retrievals using meteor radars

Autor: Iain M. Reid, Robert A. Vincent, J. P. Younger, S. Kovalam

Publikováno v: Geophysical Research Letters. 37

[1] The ability of all-sky interferometric meteor radars to measure mean wind and high-frequency gravity wave wind perturbations from meteor radial velocities is assessed. A Monte-Carlo technique that models line-of-sight meteor wind measurements wit

Mount Gambier (38°S, 141°E) prototype VHF wind profiler

Autor: David A. Holdsworth, S. Kovalam, J. Stickland, Iain M. Reid, Robert A. Vincent

Publikováno v: Radio Science. 40

[1] The Mount Gambier wind profiling radar was installed in September 1997 and has operated almost continuously since the beginning of 1998. The site is at the Australian Commonwealth Bureau of Meteorology Mount Gambier Meteorological Office, close t
