Remove the loop for marker is really good suggestion. But I don't think I swapped the X and Y arguments.

Actually, if you check my plot carefully (pressure on Y axis and latitude on X axis), just some dots are missing (i.e. dots at 850hPa). And also I don't think my values are out range of my data because I use the whole data (not subset) to plot.
