Description
Entrainment plays an important role in the convective process, and the original Tiedtke Convective Scheme is using a simplified entrainment formula which is based on the equation 6.7 in the IFS document (Cy40r1 version). More sophisticated entrainment formula, which is based on Bechtold et al., (2008), is introduced in the Tiedtke Convective Scheme. In this updated the Tiedtke Convective Scheme, users can choose one option between the original simplified entrainment equation and the sophisticated entrainment formula of Bechtold et al., (2008). The option icu_zoentr=1, which is a default setting, uses the original simplified entrainment equation while the option icu_zoentr=2 uses the equation of Bechtold et al., (2008).
Solution
Several lines of the Tiedtke Convective Scheme code are modified so that the code has two different options for the entrainment equation. Namelilst is also modified so that the users can select the option that they want to use. The default setting uses the original entrainment formula which is being used in the original Tiedtke Convective Scheme.
