Graphs are usually divided into bar and line graphs,
or the graph may be a combination of the two. Figure
6-5 is an example of a bar graph and a line graph
showing the same information. Figure 6-6 shows a
combination of a bar and line graph used to depict cloud
cover. This type of depiction is used in the most recent
U.S. Navy Marine Climatic Atlas of the World.
AVAILABILITY OF DATA
Command activity should have climatological records
available for their area and for such other areas as may
be necessary to provide climatological support at the
local command level. Various climatological records
are available from Fleet Numerical Meteorology and
Oceanography Detachment (FNMOD), Asheville, NC
28801-2696, or by contacting their website. These
records include the Summary of Meteorological
Observations, Surface (SMOS); Local Climatological
Data (LCD); Summary of Synoptic Meteorological
Meteorological Observations, Radiosonde (SMOR).
Frequency SMOS summaries are prepared for all
meteorological records (MMRs). Each SMOS is for a
specific station. Frequency distributions for various
parameters are presented by time of day, month, and
year. SMOS are revised every 5 years.
Local Climatological Data Summary
The LCD summary is prepared only for selected
civilian stations in the continental U.S.A. (CONUS). It
precipitation, wind, etc.) by month, mean temperature
and total precipitation by month for specific years of
record, and monthly and seasonal degree-days. The
LCD is revised annually.
The Cross Wind Summary presents the percentage
of occurrence of cross winds for a given location. It is
produced only on request.
Summary of Synoptic Meteorological
The SSMO presents useful monthly and annual
tabulations of surface climatological data and various
combinations of the included parameters. SSMOs were
last updated in the mid-seventies and are supplemented
by the Near Coastal Zone Studies.
Near Coastal Zone Studies
Near Coastal Zone Studies are currently being
developed by FNMOD, Asheville, to supplement the
SMOS by providing detailed climatological data for
areas of higher interest. Near Coastal Zone Studies
present data in both graphic and tabular formats.
Summary of Meteorological Observations,
The SMOR is used to prepare monthly winds aloft
summaries, which generally include various constant
height and constant pressure levels. The summaries
contain winds aloft data, giving speeds and directions
over the period covered.
