Consider Cayuga Lake where the surface currents are established by the wind. Until noon the wind blows out of the east (an unusual occurrence but we'll assume it!) and a surface current of 10 cm/s toward the west is established. At noon the wind suddenly switches and comes from the north (more standard for the lake!) and we can assume a surface currently toward the south is immediately established at 15 cm/s. Suppose we have drogues and dye to put in the flow. Drogues are floats that track the current with little influence from the wind. Now, starting at 11:00 am we release a drogue every 15 minutes until noon. We also start releasing dye continuously. Accurately sketch the location of the drogues (place an x and a time next to each) and the shape of the dye trace between 11:00 am and 1:00 pm. Accurately sketch the pathlines, streaklines and streamlines of this flow.
