Hello, I need to plot hourly wind maps with magnitude as its background and direction arrows above it. I have 2 nc file which contains hourly data of wind magnitude i.e., u component and Wind direction i.e., v component for a month. how can I plot these based on different time interval. hereby i am attaching my both nc file named uwnd and vwnd. Please help me out. Thanks in advance. netcdf file

YOu can read the data from ncfile using ncread.
Let u, v be your wind matrices. And X, Y be your locations.
M = sqrt(u.^2+v.^2) ; % magnitude
figure
hold on
pcolor(X,Y,M) ;
shading interp
quiver(X,Y,u,v)

as i am getting an error in this line.
Error using date2time (line 55)

This kind of wind vector plots are possible in MATLAB?? Kindly help!
The attached image shows the wind vector plots in the vertical axis. I need the help regarding the arrows only!
Thanks in Advance
