| Title: | Modeling the high-latitude equinoctial asymmetry / Anasuya L. Aruliah, J. Schoendorf, A.D. Aylward, M.N. Wild. |
| Author(s): | Aruliah, Anasuya L. Schoendorf, J. Aylward, A. D. Wild, M. N. |
| Date: | 1997. |
| In: | Journal of Geophysical Research. (1997.), Vol. 102(A12) (1997) |
| Abstract: | Interferometer measurements of neutral winds and radar measurements of plasma velocities have shown significant equinoctial asymmetry in average behaviour of thermosphere and ionosphere above northern Scandinavia. It is suggested that asymmetry arises from diurnal variation in cross polar cap potential difference, because there is 12 hour phase difference between variations at March and September equinoxes. Effect is Russell-McPherron Effect, which has been simulated in laboratories, and implies that auroral oval may be unexpectedly smaller at solar minimum. |
