尝试使用包裹配置文件时出现问题

issue trying to use parcel profile

这里是新手。

我在尝试使用 parcel_profile 时遇到了一个问题 运行,它一直在提示该变量没有与之关联的单位的错误:

回溯(最近调用最后): 文件 "Advanced_Sounding_3Dnetcdf2.py",第 165 行,位于 prof = mpcalc.parcel_profile(p, T[0], Td[0]).to('degC')

有问题的代码片段:

p = phPa * units.hPa
T = TdegC* units.degC
Td = TddegC* units.degC

lcl_pressure, lcl_temperature = mpcalc.lcl(p[0], T[0], Td[0])
skew.plot(lcl_pressure, lcl_temperature, 'ko', markerfacecolor='black')

print(p)

prof = mpcalc.parcel_profile(p, T[0], Td[0]).to('degC')

当我打印 'p' 时,它看起来像下面这样:

[<Quantity(965.2435302734375, 'hectopascal')>
 <Quantity(959.7489624023438, 'hectopascal')>
 <Quantity(954.278564453125, 'hectopascal')>
...

数据读入为:

file = 'cm1out_000001.nc'
figname = 'control'
figtime = '1'

f = Dataset(file, 'r')

[deleted for brevity]

th = f.variables['th'][0,0:zfl,yfl,xfl] #Read in potential temperature
p0=f.variables['prs0'][0,0:zfl,yfl,xfl] #Read in base state pressure
p = f.variables['prs'][0,0:zfl,yfl,xfl] #Read in pressure

[deleted for brevity]

phPA = p/100

[deleted for brevity]

p = phPa * units.hPa

我这里还有编码错误还是其他地方不对?

谢谢。

netCDF4-python 默认情况下为您提供屏蔽数组,这些数组在 Pint 的单位支持方面存在一些奇怪的问题。在左边乘以单位应该可以解决这个问题:

p = units.hPa * phPa
T = units.degC * TdegC
Td = units.degC * TddegC
