L'article du mois (octobre 2019)


Sarah-Sophie WEIL, Albin ULLMANN, Pierre CAMBERLIN. Climatologie, vol. 15 (2018)

Apple tree bloom onset in Germany has advanced by 2 days/decade in 1951-2014 and by 3 days/decade in 1988-2014, behaving similarly in respect to its evolution since 1951 and its sensitivity to temperature to other species’ phenological spring phases. The evolution however was not linear; by conducting a split moving-window dissimilarity analysis (SMWDA) we were able to detect the “break-period” 1987-1989 which coincides with a breakpoint that has been identified in the phases of the North Atlantic Oscillation (NAO).

    On the Angola Low interannual variability and its role in modulating ENSO effects in southern Africa.

    Pascale S, B Pohl, S B Kapnick & H Zhang (2019) Journal of Climate, 32, 4783-4803. doi:10.1175/JCLI-D-18-0745.1

    The Angola low is a summertime low pressure system that affects the convergence of low-level moisture fluxes into southern Africa. Interannual variations of the Angola low reduce the seasonal prediction skills for this region that arise from coupled atmosphere–ocean variability. Despite its importance, the interannual dynamics of the Angola low, and its relationship with El Niño–Southern Oscillation (ENSO) and other coupled modes of variability, are still poorly understood,

    Heat wave occurrences over Senegal during spring: regionalization and synoptic patterns

    Sambou M-J G, S Janicot, B Pohl, D Badiane, AL Dieng & A Gaye International Journal of Climatology, in press.

    Based on twelve Senegalese stations of the Global Summary of the Day (GSOD) database (1979‐2014), Heat Waves (HW) are defined for each station in spring (March‐April‐May, the hottest season in Senegal) as the daily maximum temperature (Tx), minimum temperature (Tn), or average apparent temperature of the day (AT), exceeding the corresponding 95% mobile percentile for at least three consecutive days.

    The light-deficient climates of Western Central African evergreen forests.

    Rainfall thresholds under which forests grow in Central Africa are lower than those of Amazonia and SE Asia. Attention is thus regularly paid to rainfall whose seasonality and interannual variability has been shown to control Central African forests’ water balance and photosynthetic activity. Nonetheless, light availability is also recognized as a key factor to tropical forests. Therefore this study aims to explore the light conditions prevailing across Central Africa, and their potential impact on forests traits.
