Dear Sabeerali
One trick will be to overlay two plots. A default with thin arrows for all
winds, then delete the wind vector values that are not significant a re-plot
the vectors with thick arrow lines. Finally, overlay the two plots.
Good luck,
Andrea

I made the composite of wind vectors (for u and v components)..Also I have done the significance test by using ttest.(s1=31 and s2=1891) separately for u and v.Now I want to plot the composite in which the wind exceeding 95% are to be represent in bold arrows and winds which is not significant are to be represent in thin arrows..How I can do this in ncl ? sX=31 sY=1891 alpha_u = 100.*(1. - ttest(aveX_u, varX_u, sX,aveY_u,varY_u,sY,True,False)) alpha_v = 100.*(1. - ttest(aveX_v, varX_v, sX,aveY_v,varY_v,sY,True,False)) Any help would be appreciated... Thanks in advance.. -- ********************************** Sabeerali Climate and Global Modeling Division Indian Institute of Tropical Meteorology Pashan, Pune, 411 008 **************************************** _______________________________________________ ncl-talk mailing list List instructions, subscriber options, unsubscribe: http://mailman.ucar.edu/mailman/listinfo/ncl-talk
