<div>By using the standard deviation formula (minus the average part), constant the longitude and level for example<br>
</div>
set t 1 48<br>
</div>
set lon 180<br>
set lev 200<br>
</div>
set lat -40 40<br>
<br>
ave1=ave(sstk,t=1,t=48)<br>
stdev2=sqrt(pow(ave1-sstk,2))<br>
</div>
This however is not seasonal standard deviation.<br>

<br>
is there a way of plotting standard deviation as a time series. I am trying to plot a seasonal mean which I accomplished... now i want to draw a curve of +/- interannual variability. All that i see in the manual gives me a single number when i do the calculations. Thanks.</font></font><span class="HOEnZb"><font color="#888888"><font color="black" face="arial">
