THE INFLUENCE OF ENSO AND QBO ON CYCLOGENESIS IN THE MOZAMBIQUE CHANNEL

Climatology

This study aims to investigate the influence of ENSO and QBO phenomena on cyclogenesis in the Mozambique Channel during the cyclonic seasons from 1979 to 2018. The study area is delimited by longitudes ranging from 35°E to 45°E, and latitudes ranging from 12°S to 24°S. In summary, although ENSO may have significant impacts on weather patterns globally, its effects on cyclogenesis in the Mozambique Channel can be modulated by a combination of local and regional factors specific to this area, such as submarine topography, wind shear, and sea surface temperature gradients. Conversely, the West phase of the QBO is much more conducive to cyclogenesis and cyclone intensification in our study area than the East phase of the QBO. However, its specific impact on cyclogenesis in the Mozambique Channel may be influenced by a complex combination of factors, including interactions with other climate variability modes and indirect effects on oceanic conditions.
