This book was released on 1977 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defense Meteorological Satellite Program (DMSP) and Synchronous Meteorological Satellite (SMS-2) digital satellite data, both visual and infrared, are processed and analyzed in context with transient/stationary synoptic ship reports, in an effort to identify areas of marine fog occurrence. The eastern North Pacific Ocean was chosen as the area of study; for various reasons the period was limited to 5-9 August 1976. Histograms and two-dimensional plots of visual and infrared data are generated as a function of five categories of fog/no-fog occurrence. Optimal ranges of visual and infrared digital count values associated with each of the five categories of fog occurrence in the study area are proposed. In addition, the height of the cloud base is computed for all processed SMS-2 data points, based on a formulation derived from radiation physics and empiricism available from the University of Wisconsin. Insofar as advancing the skill of objectively identifying marine fog areas from weather satellite observations is concerned, the results of this study are considered suggestive but not definitive, in part due to the limited data sample. The relation of the study to prior work at the Naval Postgraduate School, using NOAA polar-orbiting satellite data, is noted. (Author).

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 Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1979-11-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 23 (thesis year 1978) a total of 10,148 theses titles from 27 Canadian and 220 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 23 reports these submitted in 1978, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Book Synopsis The Use of Meteorological Satellites for Discerning Marine Fog by : Richard Thomas Wallace
Download or read book The Use of Meteorological Satellites for Discerning Marine Fog written by Richard Thomas Wallace and published by . This book was released on 1975 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate charting of marine fog distribution is made difficult because of the sparseness of transient-ship observations. The meteorological satellite offers the possibility of improving fog diagnosis by specifying areas (vice a discrete number of points) of marine fog. The study explores the feasibility of using meteorological satellite data, visual and/or infrared, as means of discerning the presence of marine fog. Transient-ship and satellite data from a summer-season period in 1973, eastern North Pacific Ocean, served as data base. A qualitative comparison is made between NOAA-2 satellite imagery and verifying marine fog, as determined from the synoptic-time ship data; qualitative guidelines for diagnosing the presence of marine fog from the visual and infrared imagery were formulated. A quantitative determination of the presence of marine fog, using visual and infrared NOAA-2 digital satellite data, is presented, from which a technique is developed for objectively diagnosing regions of marine fog.

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 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).

This book was released on 1979 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: GOES West Infrared (IR) and Visual (VIS) satellite observations for the North Pacific Ocean area, 35-55N, 120W-180, at 2345 GMT for eight June/July 1978 dates are processed to yield 20 statistical parameters which are analyzed for their use in discerning the existence of marine fog. The exploratory sample of 522 satellite observations, at 3 nmi x 3 nmi resolution (at subsatellite point) are related to the associated 0000 GMT synoptic ship reports which serve the role of ground truth. The best discrimination between fog/no-fog observations, using the statistical parameters, occurs for stratification of the data by the meridional component of the wind (south vs north), IR temperature (> or = 269 K vs 269 K) and the standard deviation of IR temperature (
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 A Climatology of Marine-Fog Frequencies for the North Pacific Ocean Summer Fog Season by : Gary Roland Willms
Download or read book A Climatology of Marine-Fog Frequencies for the North Pacific Ocean Summer Fog Season written by Gary Roland Willms and published by . This book was released on 1975 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study continues the Naval Postgraduate School's development of a computerized program to establish climatological marine-fog frequencies. In particular, fog related information contained in the visibility-weather group elements of the primary synoptic surface reports is segregated into 39 fog categories. Representative fog durations for each category are statistically established from North Pacific Ocean Weather Station summer-season data at Ships, P, Q, and S. Climatological frequencies over the North Pacific Ocean, 30-60N, for the months of June, July, August and September are derived from 12 years (1963-74) of OWS and transient ship observations (about three-fourths of a million reports). Comparison to previously published climatological frequencies is made. (Author).
