a = addfile("wrfout_d01_2000-01-24_12:00:00.nc","r")
qv = a->QVAPOR
P = a->P ; perturbation
Pb = a->PB ; base state pressure
P = P + Pb ; total pressure
theta = a->T ; perturbation potential temperature (theta+t0)
theta = theta + 300.
TK = wrf_tk (P, theta) R
H = wrf_rh (qv, P, TK)
printVarSummary(RH)
我想问theta = theta + 300. 这必须得加300么,如果我的wrfout*文件中
float T00(Time=25); :FieldType = 104; // int :MemoryOrder = "0 "; :description = "BASE STATE TEMPERATURE"; :units = "K";T00是等于290的,是否应该变成theta = theta + 290 |
