grads
很多常用grads的gs代码 function main(args) 'reinit' if(args='') 'quit' else ctl=subwrd(args,1) picdir=subwrd(args,2) maxt=subwrd(args,3) libpath=subwrd(args,4) endif 'open '%ctl 'set lat -30 90' 'set lon 0 180' 'set mpdset cnworld' 'set mproj nps' t=1 while(t<=maxt) 'set t 't level.1=1000 level.2=925 level.3=850 level.4=700 level.5=500 level.6=200 level.7=100 i=1 while(i<=7) 'set lev 'level.i 'q dims' timeline=sublin(result,5) time=subwrd(timeline,6) year=substr(time,9,4) month=substr(time,6,3) if(month='JAN');month='01';endif if(month='FEB');month='02';endif if(month='MAR');month='03';endif if(month='APR');month='04';endif if(month='MAY');month='05';endif if(month='JUN');month='06';endif if(month='JUL');month='07';endif if(month='AUG');month='08';endif if(month='SEP');month='09';endif if(month='OCT');month='10';endif if(month='NOV');month='11';endif if(month='DEC');month='12';endif day=substr(time,4,2) hour=substr(time,1,2) time=year%month%day%hour levline=sublin(result,4) lev1=subwrd(levline,6) say time ' ' lev1 * * T = temperature in deg C; * es = saturation vapor pressure in mb; * e = vapor pressure in mb; * RH = Relative Humidity in percent; * lev = surface pressure in mb; * q = specific humidity in kg/kg. *
