Hello,<br><br>The picture attached is a slice of longitude 180E, from 40 S to 20S. As you can see, the core that I wanted is at the 23S with wind speed of 18. I have tried using maximum value function in grads, as well as maximum location, but it would give me 39S corresponding to a core below 40S, which I do not want. I would like to request suggestion on solving this problem. Changing the latitude range to less than 40S however is not acceptable, as at certain condition the core can be at 38 S. <br>
<br>Sincerely, <br>Muhammad Yunus<br>
