<div dir="ltr">Hi <span style="font-size:12.8px">Zhifeng,</span><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Without seeing a script or the data, there is no way to know from our end. Have you tried creating a Skew-T (</span><span style="font-size:12.8px"><a href="http://www.ncl.ucar.edu/Applications/skewt.shtml">http://www.ncl.ucar.edu/Applications/skewt.shtml</a>) to look at your data? The CAPE values calculated from the Skew-T will be a little different than what is used by wrf_cape_3d, since I think the Skew-T CAPE only calculates surface based CAPE. But, it should give an idea of how high the values could be. If you're seeing wildly different results, then we would need to see the data to investigate. </span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Hope this helps,</span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Bill</span></div><div><span style="font-size:12.8px"> </span></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Mar 19, 2017 at 9:22 PM, Zhifeng Yang <span dir="ltr"><<a href="mailto:yangzf01@gmail.com" target="_blank">yangzf01@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi <br><br></div>I used function "wrf_cape_3d" to calculate CAPE and CIN.
