This book was released on 1981 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine fog forecasts during the summer period in the North Pacific are not made presently with any acceptable degree of accuracy. Objective fog development models exist and are used with some success for localized coastal regions of the western U.S.; scarcity of accurate data has hindered creation of a reliable open-ocean model. The Eulerian single-station approach, utilizing a segment of the complete accurate data of Ocean Weather Station Papa (50N, 145W) is applied in this study to an objective marine fog forecasting model. The time-series study of significant atmospheric variables at OWS Papa, when coupled with a chronological synoptic overview, delineates accurately fog/no fog sequences in the summer months of 1973 and 1977. Actual observed fog situations are evaluated by the general model and presented in relation to open-ocean fog indices, NOAA 5 satellite coverage and synoptic history. The open-ocean forecast model is tested on an independent data set for the month of July 1975 at OWS Papa, with favorable results. The research delineates four required indices that must all be positive to forecast fog. These indices, when plotted daily in the region of OWS Papa allow a single station to predict, with some confidence out to twenty-four hours, the occurrence of advection fog. (Author).

Book excerpt: Aircraft measurements made offshore during a coastal fog sequence by R.A. Markson are analyzed. Fog occurrence and areal extent are determined using aircraft, ship and shore station observations obtained during the Cooperative Experiment in West Coast Oceanography and Meteorology--1976 along with analyzed satellite visual and infra-red imagery. The offshore conditions are compared with those at the shore stations using selected fog indices. Photographs of special features observed are included. The offshore conditions are classified into phases by assigning limits within the specified fog indices used in the modified Leipper fog model. The sequence of observed fog events is compared to the ideal sequence. The trends in the sequence are analyzed and a general relationship between the phase sequence and the local offshore flow is indicated. The Leipper indices, the San Diego raob and the sequential fog model appear to be useful in fog prediction for the nearshore oceanic region from San Diego the Point Conception. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: "The Coastal Ocean Modeling Framework for NOAA’s High Performance Computer (COMFHPC) is an end-to-end set of common tools for the NOAA National Ocean Service’s (NOS) operational three-dimensional hydrodynamic model-based coastal ocean forecast systems. These forecast systems, in general, are jointly developed by the Center for Operational Oceanographic Products and Services (CO-OPS) and the Coast Survey Development Laboratory (CSDL) of the Office of Coast Survey (OCS) of the National Ocean Service, and implemented and run on NOAA’s High Performance Computers operated by the National Weather Service’s (NWS) National Centers for Environmental Prediction’s (NCEP) Central Operations (NCO). The COMF-HPC consists of a set of standards and a comprehensive software infrastructure which is shared by all NOS’ hydrodynamic-model operational forecast systems used to generate all input files, such as meteorological forcing, lateral open boundary forcing, river forcing, and model runtime control files, etc. required to run a NOS Operational Forecast System (OFS) which are based on hydrodynamic models. The use of COMF-HPC by all NOS operational forecast systems will allow a multiplicity of forecast systems to be operated and maintained in an efficient and robust manner. COMF-HPC will help to ensure a high time-and-cost efficiency for OFS development, transition, and operational maintenance. This document is organized as follows. Section 1 introduces the background of the COMF-HPC, including its development history, infrastructure, and data flows and the logics of the OFS execution. Section 2 describes the data sets and static files involved in the COMF-HPC system. Section 3 describes the three main control files in the COMF-HPC system. Section 4 explains script and FORTRAN programs in COMF-HPC. Section 5 describes processes to implement an operational forecast system under COMF-HPC environment. Section 6 describes key immediate and final OFS output files residing in the OFS work directory. Section 7 describes the archive of the OFS outputs. Section 8 is a general instruction to diagnose and fix common failures occurred during execution of an operational forecast system. COMF-HPC was originally developed and implemented on the High-Performance Computing Systems of Central Computer System (CCS). On 25 July 2013, NOAA transitioned all NCEP operated Production Suite including NOS OFSs to the new Weather & Climate Operational Supercomputing System (WCOSS), named Tide and Gyer. Therefore, COMF-HPC was transitioned to WCOSS operating system environment as well. The major changes are using FORTRAN compiler, otherwise, there are no significant differences of COMF-HPC on CCS and WCOSS"--Executive Summary.

This book was released on 1980 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results presented here represent the initial application of a numerical model, designed originally to study snow storms occurring downwind of a warm lake, to stratus/fog systems occurring downwind of the warm water patches inthe ocean. Major differences between the two applications include: (1) an order of magnitude difference in inversion heights, with the base of the marine layer inversion being typically a few hundred meters above the surface and (2) air-water temperature differences of a couple of degrees centigrade over the ocean compared to 5-15 C over the lake. Using observed sea surface temperature patterns and meteorological conditions as imput, Lavoie model simulations reproduce quite well the location and orientation of the major axis of the cloud field and predict a maximum in liquid water content near the bright core of the observed cloud. The location of the seaward edge of the cloud pattern is reproduced but with somewhat less skill than for the other cloud field features. This limited feasibility study has demonstrated that a significant potential exists for developing a stratus cloud-fog forecasting method based on a suitably modified version of the Lavoie model which uses satellite imagery as the basic input.
