Does anybody know of a source for wind data ~04 - 14 for E. Africa or a larger area. I have looked at a number of sources but have not found anything for these consecutive years.

The European Centre for Medium Range Weather Forecasts hosts a database with this information here: http://apps.ecmwf.int/datasets/data/interim-full-daily/levtype=sfc/
You'll want the 10 metre U wind component and the 10 metre V wind component where the U component is the wind speed from East to West, and the V component the wind speed from South to North.
To get the actual direction (in radians), you'll need the atan2 function: atan2(V, U).
