African Easterly Wave Variability and Its Relationship to Atlantic Tropical Cyclone Activity

  title={African Easterly Wave Variability and Its Relationship to Atlantic Tropical Cyclone Activity},
  author={Chris D. Thorncroft and Kevin I. Hodges},
  journal={Journal of Climate},
Abstract Automatic tracking of vorticity centers in European Centre for Medium-Range Weather Forecasts analyses has been used to develop a 20-yr climatology of African easterly wave activity. The tracking statistics at 600 and 850 mb confirm the complicated easterly wave structures present over the African continent. The rainy zone equatorward of 15°N is dominated by 600-mb activity, and the much drier Saharan region poleward of 15°N is more dominated by 850-mb activity. Over the Atlantic Ocean… 

Low-Level African Easterly Wave Activity and Its Relation to Atlantic Tropical Cyclogenesis in 2001

Abstract This paper provides new information on the low-level (850 hPa) structure and behavior of African easterly waves (AEWs) and relates this information to previous studies. Individual AEWs that
