Variability of the Turkana low‐level jet in reanalysis and models: implications for rainfall

Abstract:

The complex topography of East Africa poses challenges for accurate modelling of regional climate. The Turkana Channel in northwestern Kenya is an important feature because of a persistent low‐level jet (LLJ) which blows through it, which has complex interactions with local and regional rainfall. We establish the annual cycle and interannual variability of the LLJ in the ERA5, MERRA‐2, and JRA‐55 reanalyses. The jet is strongest during wet seasons in the surrounding region. Results suggest a ...
