LEO, Polar Orbiting Satellites
|
|
6 satellites in orbit
|
|
Body of Air over a Large Area
|
|
Takes on characteristics of the Underlying Surface
|
|
Temperature and Moisture Characteristics are the Same
|
|
Independent circulations of cold or warm water
|
|
Generally found on either side of strong currents such as the Gulf Stream or Kuroshio
|
|
Used tactically by submarines because of the sound propagation differences that exist inside and outside the eddie circulations
|
|
Open Ocean
|
|
Littoral
|
|
Rip
|
|
Terrigenous

|
|
Sound Speed increases 2 feet/second for every increase in depth of 100 feet
|
|
Dominant controller of speed below 1000 feet in the ocean
|
|
Winds Sustained at 18-33 knots
|
|
Forecasted for harbors and inland waters
|
|
TCCOR 5 - Destructive winds are possible within 96 hours
|
|

|
TCCOR 2 - Destructive winds are anticipated within 24 hours
|
|
TCCOR 1 - Destructive winds are occurring or anticipated within 12 hours
|
|
24/7 Coverage over the same Geographic Region
|
|
Monitors weather systems and storms
|
|
4 GOES Satellites in Orbit
|
|
The types are sheet, spark, and glowing ball.
|
|
Most bioluminescence in the oceans is sheet-type
|
|
Spark-type displays are created by large numbers of crustaceans
|
|
Glowing ball displays are seen most frequently in warmer waters. Luminescent jellyfish cause many glowing-ball displays
|
|
Caused by Waves Approaching the Beach at an Angle
|
|
Increase Velocity with Increased Breaker Heights
|
|
Steep Beaches have stronger currents
|
|
Mixed/Surface Layer
|
|
Thermocline
|
|
Deep Layer
|
|
Sound Speed increases 4 feet/second for every increase in salinity of 1ppt
|
|
Effects are greatest for Ocean water in areas of high evaporation and high influxes of fresh water
|
|
Winds Sustained at 34-47 knots
|
|
Forecasted for harbors, inland waters, ocean areas, installations, and air fields
|
|
A.K.A. TIROS-N Satellites
|
|
Collects Data Globally
|
|
There are 6 POES Satellites in orbit
|
|
Average rate of air motion
|
|
Measured in nautical miles/hour or Knots
|
|
Major Currents like the Gulf Stream and Kuroshio
|
|
Spilling
|
|

|
|
Interface btwn 2 Water Masses of Different Temperatures and Salinities
|
|
Isothermal Temperature with Depth
|
|

|
|
Primary Controller of Sound Speed in the top 1000 feet of the ocean
|
|
Sound Speed increases 6 feet/second for an increase in 1 degree centigrade
|
|
Winds Sustained at 48 knots and greater
|
|
Forecasted for harbors, inland waters, ocean areas, installations and airfields
|
|
Joint venture btwn NASA and Japanese Nat'l Space Development Agency
|
|
Research the water cycle in the atmosphere
|
|
The measurement and recording of subsurface water temperature at various depths
|
|
BT data is the critical factor in determining the sound velocity profile (SVP) of a particular ocean area
|
|
NOT Associated w/ Tides
|
|
Caused by return flow of water from the beach
|
|
Form at the end of a beach where land juts out into the water
|
|
Continental Shelf
|
|
Continental Slope
|
|
Continental Rise
|
|
Ocean Basins
|
|

|
|
TS are w/in 10NM or an hour away
|
|
Gusts of 50 kts or Greater = 3/4" Hail and/or Tornadoes
