Traditional windage yaw angle calculation model does not consider the impact of meteorological factors onair power density. This paper analyzes the influencing of meteorological factors on the windage yaw angle

and pro-posed a calculating model of windage yaw angle based on meteorological. And proposes two mathematical models toanalyze the relationship between windage yaw angle and meteorology factors. Finally

simulates windage yaw angleby examples of meteorological data

and predicts windage yaw angle with modeling analysis the meteorological fac-tors. The results show that wind speed

wind direction

relative humidity

air pressure

air temperature is the maininfluence factors of windage yaw angle. The proposed mathematical models can analyze better the relationship be-tween windage yaw angle and their impacted factors

and has a high precision in windage yaw angle prediction.
