Teleconnection between global ocean SST and the rainfall variability over the Ethiopian Highland.
Is your question based on a climate change perspective? If so, theoretically, an increase in global surface/air temperatures would mean an increase in the moisture availability and an increase in global rainfall. However, there is a tendency for wet regions to be wetter and dry regions to be drier with higher temperatures. This is because, at higher temperatures, the air can hold more moisture. Over wet regions, there would be enough moisture to get saturated so that it precipitates and vice-versa for the dry regions. I am not sure how exactly it would be for ethiopian highlands (it's generally dry, right?).
Hi Roxy,
Thank you for the answer. Actually, the argument " there is a tendency for wet regions to be wetter and dry regions to be drier with higher temperatures". For example the Ethiopian Highlands plateau (EH) is wet during northern hemisphere summer with climate changes it could be drier which is opposing the argument you have mentioned. Actually, my question is mainly concerned about the climate anomaly from the global ocean not the the general climate change represented by atmospheric temperature,
Ok, I had a feeling that your questions may not be on the climate change perspective, but just in case.. The wet - wetter is a generalized view.
Hello
There is a huge bibliography on the teleconnection between tropical rainfall anomaly at regional-scale and gllobal/zonal/regional SST patterns. Some previous works about Ethiopia have already analyzed the connections either for the spring and boreal summer season. Just try "Camberlin, Hulme, Conway, Jury & Ethiopian rainfall" in scholar.google.com. Or perhaps, your question should be precised ?
