A system and method for predicting a future wind direction and speed and, based thereon, determining a future wind-driven drift and providing the information to an operator or automatically acting to adapt application parameters to better control the wind-driven drift of a fluid during application of the fluid to land or crops by an agricultural machine. A processor receives machine and meteorological data, uses a model to predict the future wind direction and speed, and accesses a drift distance database to determine and visually depict the future wind-driven drift of the fluid. A sensitive area database stores information about sensitive areas bordering the target area, which may also be displayed, to facilitate controlling the wind-driven drift with regard to the sensitive areas. The mathematical model may be a kernel filter, an autoregressive model, an autoregressive integrated moving average model, or a hybrid model which incorporates features of different models.

System and method for predicting wind direction and speed to better control drift

An apparatus, method, and system for distributing gas and/or liquid phase substance from an inlet to multiple outlets with reduced variations and distribution. The apparatus includes a body having an inlet and a plurality of outlets. In one aspect, a rotatable impeller is positioned between inlet and plurality of outlets. The impeller includes a spiral fluid pathway relative to direction of substance through the inlet so that the substance passes through the impeller and is distributed to the outlets through a spinning impeller.
