This book was released on 1975 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to develop classification equations to forecast the daily probability of occurrence of marine fog at selected locations on the west coast of the United States, using parameters easily obtainable from upper-air soundings and surface observations. In order to achieve this objective a computerized stepwise linear discriminant analysis program is extensively employed. Data input consists of surface and radiosonde observations for the five-year period 1 July 1968 to 30 June 1973 at three U.S. west coast stations, namely San Diego and Oakland, California and Quillayute, Washington. Tables showing the number of fog and no-fog cases, the classification functions, and the percentages of correct fog and no-fog discrimination are presented for each station. The most capable fog/no-fog discrimination parameters are discussed for each set of classification equations. Test results for the San Diego equations using a three-year independent data set are also shown. (Author).
Book Synopsis Marine Fog Development Along the West Coast During 1973 Using Transient Ship and Coastal Station Observations by : George Stephen Evermann
Download or read book Marine Fog Development Along the West Coast During 1973 Using Transient Ship and Coastal Station Observations written by George Stephen Evermann and published by . This book was released on 1976 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using transient ship observations, a hypothetical five phase Marine Fog Development (MFD) Model was applied to four actual cases of summer marine fog during 1973 along the central California coast. The MFD Model incorporates a phase zero or synoptic phase and a proposed Coastal Convergence Zone (CCZ) concept into previous West Coast fog models. Phase zero describes the synoptic conditions that establish the marine layer over the coastal regions and explains the presence of low stratus over cast which normally exists prior to fog development cases. The CCZ concept defines a transition zone in which warm dry continental air converges with cool moist marine air and denotes the seaward extent of coastal influence. The location of the transitory CCZ is dependent upon the strength of offshore flow of continental air from the coastal region. The location where this flow meets the prevailing northwesterlies becomes the most likely site of marine fog formation. Selected synoptic scale meteorological parameters were examined and incorporated with transient ship and coastal station observations. This appeared to be an effective technique for tracking the CCZ and identifying fog phase development. (Author).
Book Synopsis An Open-ocean Marine Fog Development and Forecast Model for Ocean Weather Station Papa by : Robert Louis Clark
Download or read book An Open-ocean Marine Fog Development and Forecast Model for Ocean Weather Station Papa written by Robert Louis Clark and published by . 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 Synopsis Fog on the Central California Coast for 1973 by : John William Beardsley
Download or read book Fog on the Central California Coast for 1973 written by John William Beardsley and published by . This book was released on 1976 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface visibility data for selected stations on the central California coast in 1973 are analyzed. Radiosonde data from Oakland for the same period are used to derive meteorological indices. The year is divided into fog-related seasons, summer and winter, based on fog occurrence on the coast; and the seasonal and daily fluctuations of the indices are examined. A fog development model for the summer is formulated and compared to actual fog cases. In the winter, with far fewer coastal fog observations, the frequent occurrence of frontal passages prevents a standard development model from being formulated and compared. Four Oakland soundings are compared with four radiosondes taken at NPS Monterey, and the Oakland Soundings are found to closely approximate coastal conditions on these days. (Author).

Book Synopsis An Investigation of Marine Fog Forecast Concepts by : C. W. Rogers
Download or read book An Investigation of Marine Fog Forecast Concepts written by C. W. Rogers and published by . This book was released on 1981 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a follow-on to eight years of field study of marine fog, an investigation of potential fog forecasting concepts was initiated. Task 1 involved examination and interpretation of synoptic scale meteorological data in terms of micro- and meso-scale marine fog data acquired by Calspan on previous West Coast field studies. The results of this investigation were summarized in an experimental 'decision tree' for use in the forecasting of marine fog. As Task 2, Calspan conducted a descriptive investigation of the circumstances and characteristics of marine fog occurring in the northern Gulf of Mexico through analysis and interpretation of fog data previously acquired by Calspan during the Panama City II experiment.

Book Synopsis Statistical Diagnostic Modeling of Marine Fog Using Model Output Parameters by : Brian Lee Van Orman
Download or read book Statistical Diagnostic Modeling of Marine Fog Using Model Output Parameters written by Brian Lee Van Orman and published by . This book was released on 1977 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagnostic model output parameters, provided by the Fleet Numerical Weather Central, Monterey, Calif. (FNWC), and the marine fog frequency climatology developed at the Naval Postgraduate School, are statistically processed in context with marine surface synoptic ship reports in order to develop a linear regression scheme to model distribution of marine fog. The study area includes a large section of the North Pacific Ocean (from 30-60N) at 0000 GMT, 1-30 July 1976. The diagnostic capabilities of the regression equations are analyzed through the use of three verification scoring systems. Improvement over climatology and FNWC's operational fog probability program (FTER), is demonstrated. Selective mappings of the regression equation outputs and categorized observations are intercompared with the sea-level pressure analysis; FTER; and the evaporative heat flux--the most significant predictor parameter.
Book Synopsis Analysis and Prediction of Visibility at Sea by : William George Schramm
Download or read book Analysis and Prediction of Visibility at Sea written by William George Schramm and published by . This book was released on 1966 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with the problem of visibility at sea and fog over the sea. Restrictions to visibility in general are discussed and suspended moisture is related to low visibilities at sea. Fleet Numerical Weather Facility at Monterey produces a field of the difference between the vapor pressures of the sea and air. This field is used as a humidity index to determine the moisture in the air and is related to visibility. A total of 1100 data points from the North Atlantic were analyzed and an attempt was made to produce a linear regression equation. The regression equation proved to be most inaccurate in the area of low visibilities. A scattergram of visibility as a function of air temperature and the vapor pressure difference revealed a significant relationship. Using this relationship it is possible to forecast visibility and fog probability.

Book Synopsis Climatological Marine-fog Frequencies Derived from a Synthesis of the Visibility-weather Group Elements of the Transient-ship Synoptic Reports by : Robert J. Renard
Download or read book Climatological Marine-fog Frequencies Derived from a Synthesis of the Visibility-weather Group Elements of the Transient-ship Synoptic Reports written by Robert J. Renard and published by . This book was released on 1975 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study presents the essentials of a method of synthesizing the visibility-weather group elements of marine synoptic reports into a computerized scheme for the purpose of deriving frequencies of marine-fog occurrence. The program, based on an interpretation of reporting guidelines in the Synoptic Code Manual, uses 16 combinations of present and past weather, and visibility, to identify fog in the reports. The program then objectively assigns the duration of fog for the period represented by each of the reports. A prototype climatology of marine-fog occurrence for July, over the North Pacific Ocean, is derived from application of the method to a ten-year data base (1963-72). Results are compared and discussed in relation to other published coastal and marine-fog climatologies. Diurnal fog frequencies at sea and the compatibility of fog observations from Ocean Weather Stations and transient ships are also treated. The continuing work and its goals are described.
Book Synopsis Numerical Prediction of Marine Fog Using the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) by : John L. Dumas
Download or read book Numerical Prediction of Marine Fog Using the Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) written by John L. Dumas and published by . This book was released on 2001-03-01 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Navy's requirement for a computer prediction system for marine fog and stratus dates back to the 1970s when meteorological models were being introduced to the fleet. The Naval Research Laboratory's Coupled Ocean/ Atmosphere Mesoscale Prediction System (COAMPS) is a leap forward in the Navy's numerical modeling ability but it still does not show great skill in fog forecasting. COAMPS has been 'tuned', or adjusted for certain constants and parameterizations, so that it has the minimum error for the maximum area. This tuning is a common practice for all numerical models. The objective of this thesis is to determine if changes can be made to the existing COAMPS code based on reasonable physical experiments for a specific location to help solve the numerical fog forecasting problem. The effectiveness of these experiments was first measured by comparing a modeled cloud edge to satellite imagery of Monterey, California taken during a week in August 2000 under a variety of foggy conditions. Comparisons were also made with observations taken from an aircraft, land stations and a vertical profiler. The experiments, specifically those regarding changes to the autoconversion and turbulent kinetic energy schemes, showed that while a perfect solution has not been found, it is possible to modify the model physics codes and optimize its performance in a specific region.
