<tt>You can delete multiple variables via<br>

<tt> delete([/intensity, duration, center_lon, center_lat/])<br>

Unfortunately, NCL doesn't support custom structures. The
best way might be to create a list for the intensity with
duration and location as attributes. Something like this:<br>
<br>
<tt>intensityList = NewList("fifo")</tt><tt><br>
</tt><tt>do i=0, nEvents-1, 1</tt><tt><br>
</tt><tt> <read in data></tt><tt><br>
</tt><tt> intensity@duration = duration</tt><tt><br>
</tt><tt> intensity@center_lon = center_lon</tt><tt><br>
</tt><tt> intensity@center_lat = center_lat</tt><tt><br>
</tt><tt> ListPush( intensityList, echo(intensity) )</tt><tt><br>
</tt><tt> delete(intensity)</tt><tt><br>
</tt><tt> delete(duration)</tt><tt><br>
</tt><tt> delete(center_lon)</tt><tt><br>
</tt><tt> delete(center_lat)</tt><tt><br>
</tt><tt>end do</tt><br>
<br>
Where echo is a function I often use with lists that
returns an anonymous copy so the list retains the variable
if it is deleted:<br>
<br>
<tt>if isdefined("echo") then undef("echo") end if</tt><tt><br>
</tt><tt>function echo(variable)</tt><tt><br>
</tt><tt> local variable2</tt><tt><br>
</tt><tt> begin</tt><tt><br>
</tt><tt> variable2 = variable</tt><tt><br>
</tt><tt> return variable2</tt><tt><br>
</tt><tt> end ; echo</tt><br>
<br>
The downside to this method is that you can't have
metadata on the duration or locations. The other option is
to create a list for each variable, which breaks their
connection but allows you to keep the metadata.<br>

<div dir="ltr">Hi, All
<div> I want to create an array of blocking
event, every event contains intensity, duration,
center_lon(duration), center_lat(duration).
because center_lon depends on the duration, so I
wonder if there is one method to create an
array, in which every member is a list to
include variable (intensity, duration) and
array(center_lon,center_lat). I think this is
similar to structure in C/C++ Language. Any help
is welcoming.</div>
