1. Phylogeography of the southern skua complex – rapid colonisation of the southern hemisphere during a glacial period and reticulate evolution

   Whilst we have now a good understanding how past glaciation influenced species at the northern hemisphere, our knowledge of patterns and modes of speciation is far more limited for the […]

2. Continuous flow analysis of total organic carbon in polar ice cores

   Ice cores are a widely used archive to reconstruct past changes of the climate system. This is done by measuring the concentration of substances in the ice and in the […]

3. The past is a guide to the future? Comparing Middle Pliocene vegetation with predicted biome distributions for the twenty-first century

   During the Middle Pliocene, the Earth experienced greater global warmth compared with today, coupled with higher atmospheric CO2 concentrations. To determine the extent to which the Middle Pliocene can be […]

5. On the use of IMAGE FUV for estimating the latitude of the open/closed magnetic field line boundary in the ionosphere

   A statistical comparison of the latitude of the open/closed magnetic field line boundary (OCB) as estimated from the three far ultraviolet (FUV) detectors onboard the IMAGE spacecraft (the Wideband Imaging […]

7. Atmospheric temperature responses to solar irradiance and geomagnetic activity

   The relative effects of solar irradiance and geomagnetic activity on the atmospheric temperature anomalies (Ta) are examined from the monthly to interdecadal timescales. Geomagnetic Ap (Ap) signals are found primarily […]

8. Possible solar wind effect on the Northern Annular Mode and northern hemispheric circulation during winter and spring

   Statistically measurable responses of atmospheric circulation to solar wind dynamic pressure are found in the Northern Hemisphere (NH) zonal-mean zonal wind and temperature, and on the Northern Annular Mode (NAM) […]

9. Decadal-scale changes in the effect of the QBO on the northern stratospheric polar vortex

   This study documents decadal-scale changes in the Holton and Tan (HT) relationship, i.e., the influence of the lower stratospheric equatorial quasi-biennial oscillation (QBO) on the northern hemisphere (NH) extratropical circulation. […]

10. Geomagnetic perturbations on stratospheric circulation in late winter and spring

    This study investigates if the descent of odd nitrogen, generated in the thermosphere and the upper mesosphere by energetic particle precipitation (EPP-NOx), has a detectable impact on stratospheric wind and […]

11. Low-altitude measurements of 2–6 MeV electron trapping lifetimes at 1.5 ≤ L ≤ 2.5

    During the Halloween Storm period (October–November 2003), a new Van Allen belt electron population was powerfully accelerated. The inner belt of electrons formed in this process decayed over a period […]

12. Longitudinal and seasonal variations in plasmaspheric electron density: Implications for electron precipitation

    The tilt and offset of the Earth’s magnetic field can significantly affect the longitudinal and seasonal distribution of electron density in the plasmasphere. Here we show that for the solar […]
