The UKMO TIGGE suite (MOTHS) was upgraded on 13 June 2007 00Z. Model Version - The UM was upgraded from Portable UM (PUM) version 6.0 to 6.1.
Stochastic Physics - Random Parameters Scheme (RP) upgraded to version 2.
- Stochastic Convective Vorticity (SCV) upgraded from version 6.0 to 6.1.
- Additionally a (portability) bug was fixed in SCV that resulted in anomalous results in the tropics.
- Stochastic Kinetic Energy Backscatter (SKEB) was introduced at version 11.3.
UM Science Pack was upgraded from cycle 34 to cycle 39 (representing the operational deterministic model active as of June 2006). The main features are: - Small improvements to mid-level convection.
- Introduction of the adaptive detrainment scheme.
- Changes to the formulation of the thermal roughness length.
- Other miscellaneous boundary level improvements.
- Updated soil parameter ancillary fields.
