One point that may be missed here is that on windy days, lets say > 5 mph, the wind and wind direction will reduce fan airflow into the ACC especially on the windward fans. If you are operating on a hot day, the loss of airflow will certainly increase your back pressure and even possibly trip the turbine. The windscreens described in the referenced report were installed only for protection of the fan blades. There have been wind screen configurations optimized using CFD Analysis, that have been proven to reduce wind related deficiencies.
