Nonetheless, during the low solar activity period, the pre-reversal enhancement drifts are much smaller to affect any nighttime density enhancement at low latitude through the described process.
Reports suggest that white race northern Europeans may have developed a partial resistance to diabetes over the centuries, becoming adapted to a lactose-rich diet through farming/animal husbandry, and to rapidly changing light at higher latitude through natural selection [ 50, 51].
This timing delay indicates the propagation of the Pc1 waves from a high-latitude source region to lower latitudes through an ionospheric duct.
The second largest forest biome after tropical systems, the boreal forests spans the higher latitudes through Canada, Alaska, Siberia, China, and Scandinavia [3, 20].
Evidence is found in the data for different entry mechanisms; sub-solar point reconnection, merging in anti-parallel fields at different locations on the dayside magnetopause, and more direct entry at high latitudes through the turbulent boundary layer.
This gives rise to electrical currents which, along with their associated electric fields [called penetrating interplanetary electric fields (IEFs)], can penetrate to lower latitudes through the conducting ionosphere (Fejer and Scherliess 1995; Fejer et al. 2008; Huang et al. 2007; Zhao et al. 2008).
The analysis consists in the calculation of TEC of the ionosphere using data from several Mexican GPS stations, with the purpose of quantifying the impact into the ionosphere to these latitudes, through the variations in amplitude, Hurst index, that is roughness, and wavelet transform of the time series of TEC.
When turbulence occurs through shear and rotation, the angular momentum can become redistributed to different latitudes through meridional flow.
The groups remained and further speciated at these latitudes through Cenozoic global cooling beginning in the Eocene.
Under a basic EC model, cool-temperate species from the Northern Hemisphere survived the LGM at lower latitude refugia and then recolonized higher latitudes through range expansion [ 6, 7].
Populations have adapted to the regional intensity of the solar irradiation in different latitudes through evolutionary changes in skin pigmentation [ 6].
