我正在尝试运行此处找到的子程序'conden'（http://mesonh.aero.obs-mip.fr/chaboureau/PUB/NCL/），因此我编写了一个'main'程序来初始化数组并调用子程序。
我在'condens'子程序中做'print'语句以找出错误，我发现每次提到逻辑变量'LUSERI'时都会出现问题（分段错误错误）。
但是，我不知道为什么。
在主程序中，我写道：
program main
logical :: luseri
...
luseri = .true.
...
call condensation(...,luseri)
end program main
（'LUSERI'是子程序中的最后一个参数）
一切似乎都没问题：主程序中的变量声明和赋值，子程序'凝结'中的声明及其提及。
这是我写的'main'程序（main_cst.f90）：

!! PURPOSE
!! -------
!!** Routine to diagnose cloud fraction and liquid and ice condensate mixing ratios
!!
!!
!!** METHOD
!! ------
!! Based on the large-scale fields of temperature, water vapor, and possibly
!! liquid and solid condensate, the conserved quantities r_t and h_l are constructed
!! and then fractional cloudiness, liquid and solid condensate is diagnosed.
!!
!! The total variance is parameterized as the sum of stratiform/turbulent variance
!! and a convective variance.
!! The turbulent variance is parameterized as a function of first-order moments, and
!! the convective variance is modelled as a function of the convective mass flux (units kg/s m^2)
!! as provided by a mass flux convection scheme.
!!
!! Nota: if the host model does not use prognostic values for liquid and solid condensate
!! or does not provide a convective mass flux, put all these values to zero.
!! Also, it is supposed that vertical model levels are numbered from
!! 1 to KLEV, where 1 is the first model level above the surface

您在通话中的内容与子程序的内容之间似乎不匹配
call condensation(klon, klev, kidia, kfdia, kbdia, ktdia, ppabs, pzz, pt, prv,
pmflx, prc, pri, luseri)
并且子程序想要
SUBROUTINE CONDENSATION( KLON, KLEV, KIDIA, KFDIA, KBDIA, KTDIA, &
PPABS, PZZ, PT, PRV, PRC, PRI, PMFLX, PCLDFR, LUSERI )
所以在调用它的prv pmflx prc pri 在子程序中它的prv prc pri pmflx。此外，您缺少一个传递给子例程的变量。 Fortran对传递的变量的顺序很敏感。在没有检查其余代码的情况下，我认为应该解决问题。
