<p>Sorry, the previous mail was sent accidentally.</p>
<p>Let me continue from the previous.</p>
<p><br>
</p>
<p>For the first warning message, </p>
<p>I set "res@gsnAddCyclic = False" but I'm getting it still.</p>
<p><br>
</p>
<p>For the second message, I checked "<span style="font-family: verdana, arial, sans-serif; font-size: 13pt; line-height: 15pt;">Non-monotonic coordinate variables</span>" as noted in "Common Graphical Error Messages" at "https://www.ncl.ucar.edu/Document/Graphics/error_msg.shtml". </p>
<p>And I checked the deltas between the longitude coordinate array.</p>
<p>Indeed, they were not constant but with very small differences as below.</p>
<p></p>
<div>(99)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(100)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(101)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(102)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>

<div>(104)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3953094</div>
<div>(105)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952789</div>
<div>(106)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3953094</div>

<div>(108)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(109)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(110)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(111)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(112)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(113)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(114)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<div>(115)<span class="Apple-tab-span" style="white-space:pre"> </span>0.3952942</div>
<br>
<p></p>
<p>Please note that most of them are constant with 0.3952942 but a few are different.</p>
<p>But they are very close. So I wonder if these small differences are causing the error in real?</p>
<p>If they are, how can I fix it?</p>
<p>Should I try to adjust trXTensionF? Then, how?</p>
<p><br>
</p>
<p>Finally, I wonder if these issues above is causing the error with my contour plot in the image attached.</p>
<p><br>
</p>
<p>Thank you very much for your help.</p>
<p><br>
