In this script, you can mask the data for the JJAS and MAM. You have to change your time and variable name according to your data.
Dear Patil
use "test.nc"
define axis/t/units=months/edges/t="15-jan-2000":"15-dec-2010":1/ calendar=360_days tmonthly
let var_anm=var_data[gt=tmonthly@asn] ! variable anomaly is the new variable name
let month=mod(l[gt=var_anm],12)
let mask1 = if month ge 3 and month le 5 then 1
let mask2 = if month ge 6 and month le 9 then 1
!<<<<<<<<<<<<<<<<<<<<<<<<<masking for mam & jjas<<<<<<<<<<<<<<<<<<<<<<<<<< <<<<<<<<<<<<<<<!
let var_mam = var_anm*mask1
let var_jjas = var_anm*mask2
define axis/t/units=years/edges/t="15-jan-2000":"15-dec-2010":1/ calendar=360_days tyearly
let var_mam_yearly = var_mam[gt=tyearly@ave]
let var_jjas_yearly = var_jjas[gt=tyearly@ave]
list var_mam_yearly
list var_jjas_yearly
