Upwind lakes do not always lead to an increase of precipitation downwind. The structure supports the turbine by 2 upwind and 2 downwind masts. The crosswind component causes the drift object to diverge from straight downwind direction. Leeward () is the direction downwind (or downward) from the point of reference. The leeward (downwind) line is called the sheet. This represents a range of wind angles between beam reach and running downwind. Bathroom fans exhausted the gases and wind carried the contagion to adjacent downwind complexes. The fallout distribution is predominantly a downwind plume. Many sailboats are significantly faster sailing on a broad reach than running (sailing straight downwind). Some turbines place the rotor behind the nacelle (downwind design). The drawing below shows the vector operations and resulting calculations for sailing downwind. Kites can be used to pull people and vehicles downwind. The gennaker used for downwind sailing is . The Captain became worried about bad weather and low clouds on the left hand downwind. Soil conditions for farming are generally good, especially downwind of volcanoes.
