7.3 Temperature
7.3.2 Description
A range of temperature models are available to support simulation of heat movement and potentially its impact on hydrodynamics via baroclinic (density driven) processes. The temperature model is typically deployed in most settings that require further environmental simulation such as water quality. Temperature simulation is activated using the
Modelling of temperature is typically coupled with atmospheric heat exchange (see Section 7.7). If temperature is simulated without atmospheric heat exchange then temperature is treated as a passive tracer.
Supported temperature model implementations are summarised in Table 7.3, with links to the relevant implementation sections below. Commands are listed in Table 7.4.
| Model Implementation | Description |
|---|---|
| None | Temperature simulation disabled. |
| Barotropic | Temperature simulated as a passive tracer without density feedback. |
| Baroclinic | Temperature simulated with density coupling (baroclinic effects). |
| Command | Description |
|---|---|
| Include Temperature | Optional - Activates temperature simulation and optionally density coupling using active and baroclinic flags. |
7.3.3 None
This model is the default and excludes the simulation of temperature.
7.3.4 Barotropic
This model includes the simulation of temperature as a passive tracer and temperature is not included in density calculations.
7.3.5 Baroclinic
This model includes the simulation of temperature and has it contribute to density calculations. It is typically used where thermal stratification or water quality processes are to be simulated. Simulation of deeper freshwater lakes and water supply reservoirs are typical applications.
