Introduction of prognostic rain in ECHAM5: design and single column model simulations

Introduction of prognostic rain in ECHAM5: design and Single Column Model simulations

Prognostic equations for the rain mass mixing ratio and the rain drop number concentration are introduced into the large-scale cloud microphysics parameterization of the ECHAM5 general circulation model (ECHAM5-RAIN). For this a rain flux from one level to the next with the appropriate fall speed is introduced. This maintains rain water in 5 the atmosphere to be available for the next time step...

Introduction of prognostic rain in ECHAM5

Interactive comment on “Introduction of prognostic rain in ECHAM5: design and Single Column Model simulations” by R. Posselt and U. Lohmann

p. 14679, l. 21: The reviewer is right by stating that a diagnostic treatment of snow is especially worrisome because of lower fall speed of snow and of the larger distances from the cloud to the surface. We are aware of that and the extension of the prognostic treatment to snow is work in progress. But as the current study focuses on warm rain processes and the effect of Giant CCN (like sea sa...

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...

Single-Column Model Simulations of Cloud Sensitivity to Forcing

The Atmospheric Radiation Measurement (ARM) Program single-column modeling (SCM) framework has to date used several fairly brief intensive observing periods (IOPs) to evaluate the performance of climate model parameterizations. With only a few weather events in each IOP, it is difficult to separate errors associated with the instantaneous dynamical forcing from errors in parameterization. It is...
