39.12 save_convection

When convection is being computed explicitly (option implicitvmix is not enabled), the instantaneous value of the component of the time rate of change of temperature due to explicit convection can be saved three dimensionally. If cell is a land cell, its value is set to a flag value = 10^-20 to denote land. If no convection has taken place in cell , the convection for that cell is zero. Otherwise

$$convect_{i,k,j} = \frac{t^{after\; convection}_{i,k,j,1,\tau+1} - t^{before\; convection}_{i,k,j,1,\tau+1}}{2\Delta\tau}$$ (39.171)

The output from this diagnostic is written only as 32 bit IEEE unformatted data to file cvct.yyyyyy.mm.dd.dta. If option netcdf or save_convection_netcdf is enabled, data is written in NetCDF format to file cvct.yyyyyy.mm.dd.dta.nc rather than in unformatted IEEE. The ``yyyyyy.mm.dd'' is a place holder for year, month, and day and this naming convention is explained further in Section 38.2. The interval between output is specified by variable exconvint and there is no control variable since only the unformatted data is written.
