How does Tibetan plateau snow cover influence summer rainfall and extremes over Africa?
Dear Asaminew,
According to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC, 2013), global mean surface temperature shows warming of 0.85 °C during 1880–2012. However, the TP has warmed much more rapidly. In situ observations, reanalyses and climate models show a clear amplification of the warming rate over the TP in recent decades.

These will be helpful for you.

Generally, the rainfall and temperature have a negative feedback effect on snow increasing. But to see the influence of snowfall in TP on extreme events in Africa, you may need to analyse the patterns and link them. This article may be a starting point for you.
