Available in PDF, EPUB and Kindle. Book excerpt: Modeling and observational studies have shown that the Great Lakes have a significant impact on wintertime cyclones as well as wintertime cold fronts that traverse this region. The purpose of the research is to develop a wintertime frontal climatology of the Great Lakes. Frontal passages were investigated for the winters of 1999/2000 through 2004/2005. Twelve-hour surface maps were used as the basis for identifying fronts that crossed through the Great Lakes Region. A more detailed analysis of the interactions of the fronts with the lakes was made for the winters of 1999/2000 and 2003/2004 using 3 and 1 hour surface maps. Frontal interaction with a lake was investigated by looking at characteristics of both the fronts and the lake/land interaction. The characteristics of the fronts that were examined were frontal intensity/gradient, speed, type, orientation to the lake, precipitation, and the wind shift across the front before it crossed the lake. The lake/land characteristics that were looked at were dewpoint depression, ice coverage, lake temperature, lake/land temperature difference and time of day. The results of the analysis for 1999/2000 and 2003/2004 seasons were combined and evaluated using basic statistics to test the statistical significance of the results.

Available in PDF, EPUB and Kindle. Book excerpt: Daily maximum and minimum air temperatures at 25 locations on the perimeter of the Great Lakes for the period 1897 to 1977 were used to generate long term daily air temperatures and freezing and thawing degree-days (FDD's and TDD's). In addition daily, weekly, and monthly FDD's and daily TDD's were calculated for the 81 summer and 80 winter seasons between 1897 and 1877. this report describes the computational procedure and presents graphs and tables resulting from this analysis. The complete analysis is too voluminous to present in hard copy, but is available on microfilm through World Data Center A, Institure of Arcic and Alpine research, University of Colorado at Boulder, Boulder Colorado 80309.

Download or read book Numerical Simulations of the Great Lakes Impact on Cold Frontal Passages written by Timothy S. Axford and published by . This book was released on 2008 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year the Great Lakes region experiences numerous frontal systems that pass through the region and interact with the large bodies of water. Given the right conditions, a frontal passage through this region can often lead to debilitation lake effect snows in the wake. Through past research, much has been learned about the effect that the Great Lakes have on weather, but the effects on synoptic-scale fronts are not well established. The purpose of this study is to determine the influence of relatively warm and cool lake surfaces on cold fronts.

Irbe and published by Environment Canada, Atmospheric Environment Service = Environnement Canada, Service de l'environnement atmosphérique. This book was released on 1992 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Study to determine the normal structure of the Great Lakes surface water temperature field and the normal variability in the field throughout the year. Grid point temperature data were used to compute the daily normal temperature and variability through the year at the grid point locations. Daily mean temperature and standard deviation were computed for each of the days of the year, for every grid point and for each lake as a whole. The lake-wide daily mean temperature and standard deviation tables and the annual temperature curves are based directly on the results of the data analyses. The beginning-of-month and middle-of-month temperature/variability maps were constructed by plotting the computed grid point temperature and standard deviation values for the corresponding day and then contouring the temperature and variability patterns.

Available in PDF, EPUB and Kindle. Book excerpt: A temperature climatology has been developed for the surface and ten 10-m layers along the normal ship route between the eastern and western ends of Lake Superior and for discrete areas along the ship route. Base period for the climatology includes winters 1973-76 and falls 1976-79. Daily average temperatures and extreme temperatures for the base period were calculated, and a sixwave Fourier equation fitted to the average temperature time series to define the temperature climatology.

Download or read book Great Lakes Degree day and Winter Severity Index Update written by Raymond A. Assel and published by . This book was released on 1986 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Daily maximum and minimum temperatures at 25 stations on the perimeter of the Great Lakes for the winters of 1977-1983 are used to calculate freezing degree-days and thawing degree-days. Daily, weekly, and monthly FDD's and daily TDD's for those years are presented in microfilm appendixes, which are available from the National Snow and Ice Data Center located in Boulder, Colorado. This report also updates an 80-winter FDD climatology and presents tabulations of the seasonal maximum FDD's and TDD's for each of the 86 winters and 87 summers between 1987 and 1983. The maximum FDD's are used to revise winter severity those winters with above and below normal severity over the 86-winter base period. The period of the update is remarkable in that it contained some of the most severe and most mild winters in the 86-year period.

Download or read book Great Lakes Ice Climatology Update Winters 2006 2011 Description of the Digital Ice Cover Dataset written by Jia Wang and published by . This book was released on 2012 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A 6-winter digital ice cover data set consisting of 389 ice charts of total ice concentration (the fraction of a unit of surface area covered by ice), was downloaded from the National Ice Center (NIC) website, http://www.natice.noaa.gov/products/great_lakes.html. This report updates GLERL's 33-winter ice climatology dataset for total ice concentration (Assel 2003, Assel 2005). Data processing and quality control procedures, file structure, format, and naming conventions are described. The data are available as fixed formatted ASCII grids (2.55 km for winter 2006 and 1.275 km for winters 2007-2011) and has been converted to ArcMap feature classes for GIS users. Temporal distribution of the ice charts is summarized in tables. A planned companion report will contain an analysis of these data including spatial patterns of dates of first ice, last ice, ice duration, and ice concentration anomalies [relative to a 30-winter (1973-2002) base period] for each lake by winter season. It will also contain lake averages of total ice cover concentration that portray the seasonal progression of ice cover each winter. Since the last updated ice atlas (Assel 2005), there has been significant change in ice cover on the Great Lakes. This update of the ice atlas should be useful to the research community as well as others who rely on Great Lakes ice data for planning purposes. The technical memorandum that updated the ice atlas for winters 2003, 2004, and 2005 (Assel 2005) did not include ArcGIS feature classes, so those are included here."--Introduction.
