How to plot a Tornado?

What command shall I use to plot velocity vectors for a tornado (as shown in the adjoining figure) when I have got the velocity and pressure data?

I didn't see an attached figure, but I'll make a guess that what you want is a quiver plot.

If that is not what you had in mind, you might want to take a look at the Plot Gallery.

Sir, you can see it now. quiver looks helpful but how can I divide the regions like it has been done with the solid curve in the figure.

You will need to do that plotting in multiple steps. I suggest getting the little arrows plotted first. Then, you will need to add the additional solid lines separately.

Do you already know the function that defines those lines, or do you need to figure that out from the data? (This does not seems like a very simple thing to do.)

[Udit Srivastava]

it'll be figured out from the data. can you help me with that?

I think people here can probably help, but we're not just going to do it for you. What have you tried? Post your code and we can help.
