<div class="moz-cite-prefix">Yes, I have calculated the PTOT
correctly. <br>
<br>
In fact, the PSFC is similar to the observed one in the zone
althought with oscillations a little bit exagerated. In the
reality, there existed a gravity wave, but I cannot explain how
the model is able to capture it but not for the pression at other
levels. <br>

Thank you.<br>
