Your data has local differences that are large compared to the difference in range between the lowest and highest value, whereas the image you show as ideal has only small local differences compared to the range between the lowest and highest value.

With the relative data values you happen to have, the cost of getting rid of the peaks will be flattening out your surface plot to very nearly flat. If that is your goal, you might as well use pcolor().

If you do not want to do that, then zlimit to change the upper bound of plotting to be a number of times larger, which will have the effect of having the actual data occupy a smaller portion of the plot, with the result that the peaks will be less prominent.
