Using a daouble max will let you search in an area, while using triple max will let you search in a volume. Using a singe max, you need to specifiy specific lat and lon. <br><br>'set lon 90'<br>'set lat 45'<br>
'd max(temperature,lev=1000,lev=500)'<br>'d maxloc(temperature,lev=1000,lev=500)'<br>Or<br>'set lon 90'<br>'d max(max(temperature,lat=60,lat=20),lev=1000,lev=500)'<br>'d maxloc(max(temperature,lat=60,lat=20),lev=1000,lev=500)'<br>
Or<br>'d max(max(max(temperature,lon=0,lon=90),lat=60,lat=20),lev=1000,lev=500)'<br>'d maxloc(max(max(temperature,lon=0,lon=90),lat=60,lat=20),lev=1000,lev=500)'<br> <br>You can also add one more max for t as well, but that is going to take more processing time. Alternatively, you can also use amax for area maximum. I do hope that soon, a volume max function will be added.<br>

Hi,<div><br></div><div>I am trying to figure out how to find the maximum temperature in a vertical layer, between the surface and 500 millibars. I have searched through the gradsusrs digest and can't</div><div>quite figure out how to do it. </div>
<div><br></div><div> Using the findlvl gives you level of a certain value, but I want the maximum value between two levels, and that function doesn't seem to do that. </div><div><br></div><div> Ideally, I could do something like this </div>
<div><br></div><div><ul style="font-size:medium;background-color:rgb(224,240,255)"><code><font face="Times New Roman">d fndlvl (t, const(t,max), lev=psfc, lev=500)</font></code></ul><ul style="font-size:medium;background-color:rgb(224,240,255)">
<code><span style="font-family:arial">and it would give me the max temp and the level it found it</span></code></ul><div><font size="3">Any help would be appreciated. </font></div></div><div><font size="3"><br></font></div>
