Autor: Christopher Lennard, Jesse Kisembe, Alice Favre, Alessandro Dosio, Geoffrey Sabiiti, Alex Nimusiima

Publikováno v: Theoretical and Applied Climatology. 137:1117-1134

The study evaluates the ability of ten regional climate models (RCMs) to simulate the present-day rainfall over Uganda within the Coordinated Regional Downscaling Experiment (CORDEX) for the period 1990–2008. The models’ ability to reproduce the

Cut-off Lows in the South Africa region and their contribution to precipitation

Autor: Bruce Hewitson, Christopher Lennard, Alice Favre, Ruth Cerezo-Mota, Mark Tadross

Publikováno v: Climate Dynamics. 41:2331-2351

The contribution of Cut-off Lows (CoLs) to precipitation and extreme rainfall frequency in South Africa has been quantified from 402 station records over the period 1979–2006. Firstly, 500 hPa CoL trajectories over Southern Africa and surrounding o

The influence of ENSO on winter rainfall in South Africa

Autor: Yves Richard, Alice Favre, Mathieu Rouault, Nathalie Philippon

Publikováno v: International Journal of Climatology. 32:2333-2347

Whereas the impact of ENSO on the African summer rainfall regions is largely documented and still regularly investigated, little is known about its impact on the winter rainfall regions located at the southwestern and northwestern tips of Africa. Yet

Relationships between cut-off lows and the semiannual and southern oscillations

Autor: Alice Favre, Bruce Hewitson, Christopher Lennard, Ruth Cerezo-Mota, Mark Tadross

Publikováno v: Climate Dynamics. 38:1473-1487

The characteristics of Southern Cut-off Lows (CoLs) are studied for the period 1979–2008. The systematic identification of CoLs is realized by applying an original automated scheme using mean daily geopotential height and air temperature at 500 hPa

North Pacific cyclonic and anticyclonic transients in a global warming context: possible consequences for Western North American daily precipitation and temperature extremes

Autor: Alice Favre, Alexander Gershunov

Publikováno v: Climate Dynamics. 32:969-987

Trajectories of surface cyclones and anticyclones were constructed using an automated scheme by tracking local minima and maxima of mean daily sea level pressure data in the NCEP-NCAR reanalysis and the Centre National de Recherches Meteorologiques c
