Hi,
I am arz student of MSc finally year . As a part of my project work , i am
working with cyclone contour plotting.I am dealing with cyclone phailin and
i want to get minimum value contour plot for mean sea level pressure of
cyclone.Actually there is no error showing even though i am getting a wrong
value. I can't find what wrong with this .can you please help me to clarify
it.
I am dealing with an intensified cyclone plot but not getting a result as
expected. Please help me.
I hereby attaching the data and ncl script used.
