'd maxloc(mag(ugrd,vgrd),lev=1000,lev=850)' will give you the z level of maximum wind speed. If your pressure levels are in 25 mb increments, then the pressure level is just 1025 - 25*Z, where Z is the maxloc and it is assumed your lowest pressure level is at 1000 mb.<br>

<div>I have winds (ugrd, vgrd) at various pressure levels and want to calculate the maximum low-level winds, for instance. So, I may want to get the maximum winds over a region from 1000 mb up to 850 mb. How can I go about doing this?</div>
