FLEET NUMERICAL OCEANOGRAPHY CENTER UNIT 4LESSON 2 OVERVIEW Identify and interpret major meteorological and oceanographic products produced and issued by the Fleet Numerical Oceanography Center.OUTLINE Surface weather charts Upper-air charts Freezing-level charts Oceanographic charts Message products Acoustic Range Prediction Products FLEET NUMERICAL OCEANOGRAPHY CENTER METEOROLOGICAL AND OCEANOGRAPHIC PRODUCTS The Fleet Numerical Oceanography Center (FLENUMOCEANCEN or FNOC) Monterey, California, produces computer-generated meteorological and oceanographic charts a messages for use by Naval Oceanography Com-mand (NOC) units, the Navy, and the Department of Defense. The data from which meteorological and oceanographic charts are derived is transmitte from FNOC to NOC Centers via the Naval En-vironmental Data Network (NEDN) to Naval En-vironmental Display System (NEDS) terminals. The NEDS units (AN/FMC-l) store the data. NEDS operators are then able to produce the charts on their NEDS terminals, They are also able to transmit any or all of this data to NOC facilities and/or detachments having a NEDS-1 unit (AN/FMC-2). The centers can also include these charts as part of their facsimile transmission schedule to the Fleet. Many Department of Defense users other than the Navy, and other U.S. Government agencies, such as the U.S. Coast Guard and Nationa Oceanic and Atmospheric Administration (NOAA) activities, receive FNOC charts and products via the joint Navy/NOAA Oceano-graphic Data Distribution System (NODDS). This system allows charts and products to be received on desk-top computers using a telephone modem. The major benefit derived from computer-generated charts is the time saved by not having to plot and analyze the data. A major problem with these charts is that analysts and forecasters work from finished products, and do not analyze the observations used to produce the charts. A great deal of meteorological insight is lost when weather observations are not studied. Fleet requests for products are sent to FNOC over the AUTODIN or NEDN communications networks, using the Automated Products Re-quests (APR) format. Learning Objective: Interpret various surface weather charts produced by FNOC. |
