Description:

"This is a description of the changes which have been incorporated into the coarse-mesh 6-layer primitive equation model (6L PE) to obtain higher model spatial resolution. This modified version of the 6L PE is referred to as the 7L PE. This change in the NMC operational NWP system is the second phase of the NMC plan (see NMC Office Note 144) to improve the numerical guidance using the IBM 360/195 computer facility of NOAA. The first phase consisted of changes in the LFM system (see TPB 206). The material for this bulletin was prepared by Dr. John A. Brown of the Development Division, NMC. Model changes were incorporated and tested by Dr. John B. Hovermale, Mr. John E. Newell, Dr. John D. Stackpole, Mr. A. J. Desmarais, and members of the System Evaluation Branch of the Development Division. Automation Division incorporated the necessary computer changes for operational implementation. The date of implementation of this change will be announced by GENOT"--Leaf [1].
