Is it possible to incorporate a second variable into the quiver code? Could the color arrows in quiver be used to represent another variable, such as temperature or humidity ? This would work similarly to the scatter code, where the arrows indicate both the direction and magnitude of the wind but in color another variable?.

Thanks

hi, is just a quiver with the ShowArrowHead option off.

quiver(x,y,u,v,0.1,'b','ShowArrowHead','off');

Look, thi is the ugly version, making a hold on of the quiver with the scatter...

quiver(x,y,u,v,0.1,'b','ShowArrowHead','off');

hold on

scatter(x,y,10,temp,'filled');

It's not possible with quiver, as @Walter Roberson mentions below.

You could try getting a similar plot via feather() instead of quiver().

Not by using quiver(). quiver() creates a quivergroup(), which internally contains two LineStrip objects. The LineStrip objects have a CData property that appears to only accept a single color.
