Cover Story: Medicanes are meteorological phenomena observed in the Mediterranean region that are receiving growing attention. The number and intensity of these tropical-like cyclones is varying—as a consequence of climate change affecting the basin—while associated damages on the coasts are often significant due to the high population density. On Nov. 7–9 2011, Medicane “Rolf” formed over the Balearic Islands sea region; during its period of maximum intensity, its winds speed peaked at over 110 km/h and an intense deep convection area enveloped its minimum pressure. This study deals with disentangling the delicate interplay of energy fluxes between atmosphere, ocean and waves during a Medicane, thoroughly exploring sensitivity to initial conditions, effects of different planetary boundary layer schemes, but also the role of oceans in fueling the event.

Decomposition Kinetics of Non-Volatile Alkanes on Urban Aerosol

  • Dimitra Karali,
  • Spyridon Rapsomanikis and
  • Achilleas Christoforidis

The decomposition kinetics of non-volatile n-alkanes that were collected in an urban environment were studied. The quartz filters that they were collected on were exposed in two reactors, in dark and natural light conditions, for four days. Ambient a...

Enteric Methane Emissions Estimate for Livestock in South Africa for 1990–2014

  • Mokhele Edmond Moeletsi,
  • Mphethe Isaac Tongwane and
  • Mitsuru Tsubo

Methane (CH4) from enteric fermentation is one of the main anthropogenic greenhouse gas (GHG) emissions in South Africa. Livestock population data from 1990 to 2014 and emission factors were utilized in estimating CH4 emissions as per the 2006 IPCC (...

  • Alishir Kurban,
  • Xiuliang Yuan,
  • Tao Pan and
  • Philippe De Maeyer

As the main anthropogenic greenhouse gas that contributes most to global warming, CO2 plays an important role in climate changes in Central Asia. Due to the lack of studies of near-surface CO2 in this region, we first confirmed the applicability of t...
