Publication 
Environmental Conditions Within Specified Geographical Regions 
Publication Date: April 1973 
Location: The offshore east and west coasts of the United 
States and in the Gulf of Mexico 
Period of Coverage: Varies for each type of data presented 
Contents: This report was published to provide an analysis of regional 
climatological environmental conditions for planning data-buoy tests; 
assistance in definition of requirement; and support of engineering design, 
deployment, and tests for buoys and buoy networks for NOAA's National Data 
Buoy Center. It was prepared by an interagency ad hoc task force containing 
experts from US Navy and various data centers within NOAA coordinated by the 
National Oceanographic Data Center. A total of 31 tables and 194 figures are 
presented for physical oceanographic information which include: 
(a) Monthly surface wind, sea, and swell. 
(b) Wave period-height and period-duration graphs. 
(c) Persistency of favorable and unfavorable seas at selected wave 
conditions. 
(d) Percent of days hurricanes and tropical storm originated, by month 
or combination of months. 
(e) Percent of days hurricanes and tropical storms occurred, by month or 
combination of months. 
(f) Percent of days with tropical cyclone winds in speed classes. 
(g) Maximum winds from tropical cyclones, by recurrence interval and 
season. 
(h) Tropical cyclone center movement speed roses. 
(i) Time cross section of significant wave height. 
(j) Wave spectra by wave height interval. 
(k) Seasonal vertical temperature structures. 
(1) Surface current roses, by region and season. 
(m) Maximum observed current speeds. 
(n) Mean geostrophic surface currents and flows. 
(o) Many other types of data.
