Request for script

   Dear NCL users, Greetings. I am new to NCL script. I have the NCEP data of ‘slp.mon.mean.nc (three dimensional) and uwnd.mon.mean.nc’(four dimensional) for the period of 1976 to 2006. From these data now I want to calculate the monsoon index by using the following equation Index = (U850hpa – U200hpa)/SD (100-130 E, 0-10 N) + (SLP160 E – SLP110 E)/SD 10 – 50 N here sd is standard deviation of (U850hpa – U200hpa) and (SLP160 E – SLP110 E) respectively Suppose A= (U850hpa – U200hpa) and B = (SLP160 E – SLP110 E) ‘A’ has to average over the region (100-130 E, 0-10 N) and B has to average over the region between 10 – 50 N after that, the (U850-U200) and (SLP110-SLP160E) has to divided by respective standard deviations Then finally addition of both A and B Index = A/SD + B/SD Kindly anybody provide ncl script to calculate the above equation Many advance thanks for your kind help With best regards Praveen Dr.MALLUPATTU PRAVEEN KUMAR Senior Research Fellow (CSIR) Department of Chemistry S.V.
