#464 | Fixed | LAKE_SIGNELL update | ||
Description |
Please update the LAKE_SIGNELL test case to include an additional cpp option that will allow the BBL to compute the bottom orbital velocity:

#465 | Fixed | Corrected a bug in load_ts_metoffice.m | ||
Description |
Corrected a bug in matlab/4dvar/load_ts_metoffice.m. The time variable needed to include the epoch offset. Also, the time extraction conditional was incorrect. Many thanks to Ke Chen for bringing this to my attention. |

#466 | Fixed | IMPORTANT: horizontal viscosity and MIX_GEO_UV | ||
Description |
Checking the horizontal viscosity along geopotentials (MIX_GEO_UV) has been in my to-do list for very long time. We have some complains about this in the past about the model blowing-up in parallel applications and arrays out-of-range in couple of DO-loops. I checked this problem and I was able to reproduce the reported problems. I corrected the parallel bugs for uv3dmix2_geo.h and uv3dmix4_geo.h. Also corrected a missing dt factor in the biharmonic mixing. I did an analysis for each do loop and reworked all the DO-loop ranges and eliminated specifying them with local CPP directives. I wrote then in such a way that eliminated special treatment in nesting applications. I also revised and tested the tangent linear, representer, and adjoint version of these routines. I also added the new code for time-evolving, 3D viscosity coefficients. However, this time evolving capability is not yet available in adjoint-based applications. It is coded for completeness and availability in the future. Many thanks to Xinyou Lin for bringing this to my attention. Although the MIX_GEO_UV option is rarely used for momentum. I highly recommend everybody to update because this is an important correction and this bug has been in ROMS for long time. |
