An evaluation of operational and research weather forecasts for southern West Africa using observations from the DACCIWA field campaign in June–July 2016
; ; ; ; ; ; ; ; (Quarterly Journal of the Royal Meteorological Society, 2020)
Reliable and accurate weather forecasts, particularly those of rainfall and its extremes, have the potential to improve living conditions in densely populated southern West Africa (SWA). The limited availability of ... -
Atmospheric circulation patterns that trigger heavy rainfall in West Africa
; ; ; (International Journal of Climatology, 2022-04-07)
Classification of atmospheric circulation patterns (CP) is a common tool for downscaling rainfall, but it is rarely used for West Africa. In this study, a two‐step classification procedure is proposed for this region, which ... -
Bias correction of daily precipitation for ungauged locations using geostatistical approaches: A case study for the CORDEX‐Africa ensemble
; ; (International Journal of Climatology, 2022-07-22)
Climate model simulations typically exhibit a bias, which can be corrected using statistical approaches. In this study, a geostatistical approach for bias correction of daily precipitation at ungauged locations is presented. ... -
Is the soil moisture precipitation feedback enhanced by heterogeneity and dry soils? A comparative study
; ; ; (Hydrological Processes, 2021-09-09)
The interaction between the land surface and the atmosphere is a crucial driver of atmospheric processes. Soil moisture and precipitation are key components in this feedback. Both variables are intertwined in a cycle, that ... -
Multivariate Bias‐Correction of High‐Resolution Regional Climate Change Simulations for West Africa: Performance and Climate Change Implications
; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2022-03-07)
A multivariate bias correction based on N‐dimensional probability density function transform (MBCn) technique is applied to four different high‐resolution regional climate change simulations and key meteorological variables, ... -
Statistical Forecasts for the Occurrence of Precipitation Outperform Global Models over Northern Tropical Africa
Vogel, Peter;; ; ; Klar, Manuel; (Geophysical Research Letters, 2021-02-02)
Short‐term global ensemble predictions of rainfall currently have no skill over northern tropical Africa when compared to simple climatology‐based forecasts, even after sophisticated statistical postprocessing. Here, we ...
