Dear all,
<div class="">I’m trying to redraw a plot with maps, contours and vectors zooming in a specific area. To do so, I’ve set the following parameters:</div>
<div class=""><br class="">
</div>
<div class="">
<div class="">; mpres@mpLimitMode = "Corners" </div>
<div class="">; mpres@mpLeftCornerLatF = 28.0 </div>
<div class="">; mpres@mpLeftCornerLonF = -13.65 </div>
<div class="">; mpres@mpRightCornerLatF = 28.8 </div>
<div class="">; mpres@mpRightCornerLonF = -14.55</div>
</div>
<div class=""><br class="">
</div>
<div class="">The map looks nice, but the variables are not drawn accordingly to this new zoomed map. NCL overlay the original data over the zoomed map because because that’s what I’m telling it to do...</div>
<div class=""><br class="">
</div>
<div class="">I’ve taken a look to the NCL WRF tutorial about zooming in a plot, but they took another approach, locating (x,y) coordinates from the given corners and creating new zoomed variables. I think this method may be a bit outdated. I’ve also googled
in ncl-talk archives about this topic and I found an old mail (Jan 9, 2011) with a similar problem <span style="background-color: rgb(255, 255, 255);" class="">but it required a mod to WRFUserARW.ncl</span><span style="background-color: rgb(255, 255, 255);" class=""> in
order to add special resources. As it’s an old mail, is still valid? </span></div>
<div class=""><br class="">
</div>
<div class="">Is it possible to set the above limits to the contour and vector plots just by setting the left and right corner as above? If not, which is the best approach to this problem?</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>
<div class=""><br class="">
</div>
