In temperate regions, drifting kelp fields harbour cleaner wrasses and other fish which remove parasites from the skin of visiting sunfish.
The usefulness of monitoring the vertical F-region drift motions with Digisonde drift measurements is discussed.
Digisonde Portable Sounder 4 (DPS-4) ionospheric F-region drift measurements at the polar cap station Casey (110.5°E, 66.3°S geographic, 80.8°S corrected geomagnetic), Antarctica were used to derive the Casey 1997 (C97) regression model of Smith [Ionospheric F-region plasma convection at Casey – a southern polar cap station. PhD Thesis. La Trobe University, Australia, 1998].
Will it still then be a viable constitution for Northern Ireland even as, within it, the region drifts back towards majority unionist rule?
The camps followed, as Aranda people from the Western Desert region drifted in looking for work on the huge cattle stations (or ranches) that white settlers had staked out.
A comparison of averaged ionospheric F-region drifts measured by a digital ionosonde at Casey, Antarctica is made with convection patterns from the Weimer (1995) electric potential model.
Doppler shift of VHF backscatter echoes by Jicamarca radar provided more precise E and F region drifts, from which the ionospheric electric field were estimated (Balsley, 1973).
According to Galav et al. (2010), this may be due to the pre-reversal enhancement which is attributed to variation of the vertical F region drifts which are large and upward during 18 to 20 LT over the equator.
In this method, the center of the main particle set region drifts to the sub-particle set in which the total particle weight ( sum limits_{i=0}^N{w}_i ) is the largest.
Fejer et al. (1979) examined the effect of IMF on the vertical F-region drifts over Jicamarca and found the mean hourly drift between 1000 and 1400 LT to be 15.8±7.7 m/s for positive, and 18.3±7.3 m/s for negative, values of IMF-B z.
