Variable phase propagation velocity for long-range lightning location system
Zhongjian Liu, Kuang Liang Koh, Andrew Mezentsev +3
The electromagnetic wave propagation velocity at low radio frequencies is an important input parameter for lightning location systems that use time of arrival (TOA) method. This ve…
Observations of planetary waves in the mesosphere-lower thermosphere during stratospheric warming events
N. H. Stray, Y. J. Orsolini, P. J. Espy +2
This study investigates the effect of stratospheric sudden warmings (SSWs) on planetary wave (PW) activity in the mesosphere-lower thermosphere (MLT). PW activity near 95 km is der…
Magnetic Coordinate Systems
K. M. Laundal, A. D. Richmond
Geospace phenomena such as the aurora, plasma motion, ionospheric currents and associated magnetic field disturbances are highly organized by Earth's main magnetic field. This is d…
North-South Asymmetries in Earth's Magnetic Field: Effects on High-Latitude Geospace
K. M. Laundal, I. Cnossen, S. E. Milan +5
The solar-wind magnetosphere interaction primarily occurs at altitudes where the dipole component of Earth's magnetic field is dominating. The disturbances that are created in this…
Observational evidence for temporary planetary wave forcing of the MLT during fall equinox
Nora H. Stray, Rosmarie J. deWit, Patrick J. Espy +1
We present direct observations of zonal wave numbers 1 and 2 planetary wave activity in the mesopause region derived from a longitudinal chain of high-latitude Northern Hemisphere…
Observations of gravity wave forcing of themesopause region during the January 2013 major Sudden Stratospheric Warming
R. J. deWit, R. E. Hibbins, P. J. Espy +3
Studies of vertical and interhemispheric coupling during Sudden Stratospheric Warmings (SSWs) suggest that gravity wave (GW) momentum flux divergence plays a key role in forcing th…
