114 Metoc Flashcards
How does Naval Oceanography support the IDW mission
- varying missions bringing time dominate info in a single source package
- environmental support allows the various IDC ratings to compile, accurately interpret and predict forces intentions
US Naval Observatory (USNO)
Official source of time for the US DoD and a standard of time for the entire US
Joint Typhoon Warning Center (JTWC)
responsible for issuing tropical cyclone warnings for the Pacific and Indian Oceans
Naval Oceanography Operations Command (NOOC)
advises Navy operations on the impact of ocean and atmospheric conditions in every theater and for every operation
Fleet Numerical Meteorology and Oceanography Center (FNMOC)
provides the highest quality, most relevant and timely worldwide meteorology and oceanography support to U.S. and coalition forces from its Operations Center in Monterey, California
Naval Oceanographic Office (NAVO)
maximizes seapower by applying relevant oceanographic knowledge in support of U.S. National Security
Geostationary Operational Environmental Satellite (GOES)
22,300 miles above the equator
Polar Operational Environmental Satellite (POES)
Circles earth in 2 hours, providing global coverage every 12 hours
Defense Meteorological Satellite Program(DMSP)
Low earth orbiting satellites provided the military with important environmental information
The National Polar- orbiting Operational Environmental Satellite System (NPOESS)
Circles earth approximately every 100 minutes
Tropical Rainfall Measuring Mission (TRMM)
Joint mission between NASA and the National Space Development Agency of Japan
Wind direction/speed
Direction- average direction from which the wind is blowing during a specified period
Speed- average rate of air motion, or the distance air moves in a specified unit of time
Temperature
the amount of sensible heat in a substance or as the measurement of molecular motion in a substance
Precipitation
includes all forms of moisture that fall to the earth’s surface, such as rain, drizzle, snow, and hail
Relative Humidity
measure of the amount of water in the air compared to the max amt of water the air can absorb, expressed as a percentage
Sky condition
used in a forecast to describe the predominant/average sky condition based upon octants of the sky covered by opaque
Atmospheric Pressure
pressure exerted by the column of air on any point on the earth’s surface; measured in milibars and inches of mercury
Air Mass
a large volume of air defined by its temperature and water vapor content
Cold Front
defined as the leading edge of a cooler mass of air, replacing a warmer mass of air
Warm Front
defined as the leading edge of an advancing mass of warm air; separates warm air from the colder air ahead
Occluded Front
formed during the process of cyclogenesis when a cold front overtakes a warm front
Restricted Visibility
any condition in which visibility is restricted to a for, mist, falling snow, heavy rainstorms, or any other similar causes
Fog
condensed water vapor in cloudlike masses lying close to the ground and limiting visibility
Sunrise/Sunset
defined as when the leading or trailing edge of the sun passes the horizon
Moonrise/moonset
defined as when the leading or trailing edge of the moon passes the horizon
lunar illumination
is the light that comes to Earth from the moon
Tropical cyclone
a warm-core non-frontal synoptic-scale cyclone, originating over tropical or subtropical waters
- tropical depression
- tropical storm
- hurricane/typhoon
Thunderstorm
from when moist, unstable air is lifted vertically into the atmosphere
Tornado/Waterspout
A vortex of rapidly moving air associated with some severe thunderstorm
Funnel Cloud
a vortex of condensed water vapor and air spinning at high velocity
