Yongxin,
I have a script that eliminates this problem by isolating the minimum SLP search to a specified grid box in the domain. The box shifts as the TC translates and the new minimum SLP pressure is found. So that at T=0, you define a grid box of 20x20 (or whatever) around the storm and search to find the MSLP in that, then at T=1 you find the lowest SLP in the grid and then shift the box to center around that point so that the minimum pressure can be found at T=2 within it... and so on.
Unfortunately, I cannot provide NCL code to do it (mine is in Matlab), but hopefully you get the idea.

I used So-Young's script to plot the track but it did not work out well since her script finds the minimum sea level pressure in the entire domain which in my case corresponds to one storm at one time and another storm at another time. I am wondering if any of you worked on similar cases before and have a script or scripts to share. Any suggestions are also highly appreciated.
