Summary

Abstract: Summary of Synoptic Meteorological Observations - Great Lakes is a historical publication archived at the National Climatic Data Center (NCDC). These publications of synoptic meteorological observations for the Great Lakes present climatic summaries for 13 major great lake areas. These data summaries are based on marine surface weather observations taken on board great lakes vessels in passage ... during the period January 1960 through December 1973. These historical publications are on microfiche and filed in the NCDC archives as follows: 1. Volume 1 Lake Ontario and Lake Erie, on 4 microfiche, 2. Volume 2 Lake Huron and Georgian bay, on 5 microfiche, 3. Volume 3 Lake Michigan, on 3 microfiche, 4. Volume 4 Lake Superior, on 5 microfiche. There is one file each for Lake Superior, Lake Huron, Lake Michigan, Lake Erie, and Lake Ontario. Each volume presents the following monthly and annual tables for each sub area: Table 1 - percentage frequency of weather occurrence by wind direction. Table 2 - percentage frequency of weather occurrence by hour. Table 3 - percentage frequency of wind direction by speed and by hour and hour groups; the mean wind speed by direction is also shown. Table 4 - percentage frequency of wind speed by hour and mean speed by hour. Table 5 - percentage frequency of total cloud amount by wind direction and the mean cloud amount by wind direction. Table 6 - percentage frequency of ceiling heights and no ceiling by wind direction. Table 7 - cumulative percent frequency of simultaneous occurrence of ceiling height and visibility and percentage frequency of low clouds. Table 8 - percent frequency of wind direction versus occurrence or non- occurrence of precipitation and varying values of visibility. Table 9 - percent frequency of wind direction versus speed with varying values of visibility. Table 10 - percent frequency of ceiling heights and no ceiling by hour. Table 11 percent frequency of visibility by hour. Table 12 - cumulative percent frequency of ranges of visibility and ceiling height by hour. Table 13 - percent frequency of relative humidity by air temperature. Table 14 - percent frequency of wind direction by air temperature. Table 15 - means, extremes, and percentiles of air temperature by hour. Table 16 - percent frequency of relative humidity by hour. Table 17 - percent frequency of air temperature and the occurrence of fog (without precipitation) versus air sea temperature difference. Table 18 - percent frequency of surface wind speed and direction versus sea height. Table 19 - percent frequency of wave height versus wave period. Table 20 - monthly and annual percent frequencies and means of sea surface temperature. Table 21 - monthly and annual average sea level pressures by hour. Monthly extremes and percentile values are also shown. The data units used are: wind direction to 8 compass points; wind speed in knots; cloud, sea, and wave heights in feet; wave period in seconds; cloud amount in oktas (eighths); visibility in nautical miles; temperature in degrees Fahrenheit: relative humidity in percent: and atmospheric pressure in millibars.

Purpose: To make a wide range of climatic data available to researchers and the public.
