<p dir="ltr">When you create the netcdf, make sure the resolution is very large. Im mobile right now so i cant check my code but try something like 1000 or even 12000.... I dont recall how big is big enough to capture the data, but you can re-run it and experiment. </p>
<p dir="ltr">The other thing is the resolution of the grid in grads. I use a regrid function at very high resolution. I think its something like... </p>

<p dir="ltr">Again the order of magnitude may be off by 10 as im not in front of my code right now. </p>
