Satellite imagery interpretation Flashcards
What are 2 means of providing accurate reference?
Lines depicting geographical and geopolitical boundaries.
Latitude and longitude lines over water
Which image sometimes display displaced geography?
POES
List the 5 characteristics of cloud pattern recognition on satellite imagery:
Size Shape Shadow Tone Texture
for proper interpretation of cloud structures on satellite, the briefer must integrate other available data, such asL
Surface reports Pilot reports RADAR Upper air soundings Surface and upper air analyisis
texture is a combination of 2 factors:
Shape at the top of the cloud
the degree of lighting
Which satellite images will display a shadow?
VIS, and NIR images
what factors will affect the tone of grey on all images?
Cloud composition
Thickness of cloud
Resolution of sensor
Enhancement curve
Why are areas of instability easier to recognize on satellite?
They have distinct, easily recognizable signatures
What are the techniques used to locate the center of a surface low?
Pattern recognition
Dynamic support deduction
Ground truthing with surface obs.
Name 6 features that would indicate instability
Brighter Responses Line of TCU/CB Air mass thunderstorms Sea/Lake Breeze convergence Active cold fronts Orographic clouds Streamers of water
what techniques are used to determine the position of a high or a ridge?
Pattern recognition
Ground truthing
which is the best imagery to use to identify the jet stream?
Water vapor (due to a sharp contrast in moisture content)
what characteristic is usually indicative of mdt to SEV turbulence?
Transverse banding
Define Deformation zone
The change in shape of a fluid mass by variations in wind, specifically shearing and/or stretching
List the 5 atmospheric processes that indicate the possibility of turbulence on satellite imagery:
Strong Surface winds Convection stationary waves Wind Shear Deformation zones
