在没有外部热源和湿气源（如辐射和地表通量）的大气模式中，湿熵通常被视为一个守恒变量。然而，大气中熵的不可逆产生和非平流输运都发生，其中许多与湿度和降水有关。这些熵源和熵汇是平衡全局熵收支所必需的。现有的计算熵的不可逆产生和非平流输运的工作被扩展到包括冰的主要影响。
Moist entropy is generally treated as a conserved variable in atmospheric models in the absence of external heat and moisture sources such as radiation and surface fluxes. However, both irreversible generation and nonadvective transport of entropy occur in the atmosphere, with many of these associated with moisture and precipitation. These entropy sources and sinks are needed to balance the global entropy budget. Existing work on calculating the irreversible generation of entropy and nonadvective transport is extended to include the major effects of ice.
