<br>
how would one define a variable that is 1 if one parameter OR another<br>
parameter is in a certain range?<br>
<br>
I have found a way of expressing "AND" by masking out values, then<br>
const'ing them and const'ing them again, resulting in a result of 1 if<br>
the variable is in the desired range, e.g. cape>500 and li<-2 in this<br>
case. When I then simply multiply the 2 expressions, I get 1 if<br>
expression 1 AND expression 2 are within the desired range and 0 (or U)<br>
if either of them isn't.<br>
<br>
'define tstorm =<br>
const(const(maskout(cape255_0mb,cape255_0mb-500),1.0),0,-u)*<br>
const(const(maskout(no4lftxsfc,(-1*no4lftxsfc)-2),1.0),0,-u)'<br>
<br>
Now, how would I express e.g. ((cape>500 AND li<-2) OR prate>20) in a<br>
similar way?<br>
<br>
Ideas, anyone?<br>
