The ocean does not influence wind speed and direction. The currents in the ocean are caused by wind speed and direction. The tides in the ocean are influenced by the phases of the moon.

Hot air balloons typically travel around 5-10 miles per hour, depending on wind conditions. The direction and speed of the wind will also influence the overall speed of the balloon.
Typically, a hot air balloon travels at a speed of around 5 to 10 miles per hour, though this can vary depending on factors such as wind speed and direction. Balloonists can control the direction of the balloon to some extent, but the speed is largely determined by the wind.
Factors that affect dune shape include wind direction and strength, sand supply, vegetation cover, and obstacles on the dune's path. Wind direction and speed determine the dune's asymmetry and orientation, while sand supply and vegetation influence the dune's stability and size. Obstacles like rocks or buildings can cause the dune to take on unique shapes as it flows around them.
It is an instrument for finding wind direction. They are usually found on the top of church spires, or tall building. They can have various shapes, but all have an arrow which points into the wind direction. The tail of the vane may have something like, ship. or farmer with a scythe etc., to balance the vanes pointer against the wind flow. Do Not confuse with an 'Ananometer', which measures wind speed.
The invention of a windsock solved the problem of accurately determining the direction and speed of the wind, especially in aviation and meteorology. Windsocks provide a visual indicator of wind conditions, helping pilots and meteorologists make informed decisions based on the wind's behavior.
