Goals of Presentation Show you different arrangements an estimate can be shown Show you a portion of the apparatuses meteorologists or FAA flight briefers use in setting up a preparation Teach you how to recognize a quickly evolving air

Grid Forecasts Allows for more exact "point" figures Separate lattices for: Temp (Max, Min, Hourly) Dew point Wind (heading and speed) Weather conditions Sky Cover Precipitation Probability QPF Can be separated into littler time increases than "today" and "this evening"

Satellites and Radar

Slide 19

Satellites-Visible Imagery Visible-measures reflected sun powered vitality Works simply like a camera-useless during the evening Brightest mists demonstrate high centralizations of particles (e.g. ice and water vapor)

Slide 20

Satellite-Infrared Imagery Infrared-measure cloud top temperature Enhances coldest temperatures Only measure most astounding mists in a layer

Slide 21

Satellite-Water Vapor Water Vapor-shows measure of water vapor in climate Aid in distinguishing upper level aggravations in environment

TAFs TAF-Terminal aerodrome conjecture Issued for a five mile span territory encompassing the air terminal Surface wind (course, speed, blasts) Visibility Weather (if necessary) Obstruction to perceivability (if necessary) Sky spread, cloud statures Non-convective low level wind shear Can give you a ballpark thought of what\'s in store

Slide 29

Cloud Clues

Slide 30

Cirrus 20000 ft+ agl Cause radiances around sun or moon Can imply methodology of an unsettling influence Appears splendid on infrared satellite, dull on noticeable

Slide 31

Altocumulus ~15,000 ft agl Indicate insecure air on high Can be an antecedent to rainstorm advancement when seen at a young hour in the day

Slide 32

Stratocumulus Develop 5,000 to 8,000 ft agl Little vertical improvement Form commonly at the highest point of blended layer close surface No noteworthy climate expected unless get to be across the board and thick

Slide 33

Towering Cumulus Cloud bases normally happen around 5,000-8,000 ft agl Signify a generally profound shaky layer creating updraft-electrical storm potential If cloud breakdown, could deliver surge

Slide 34

Cumulonimbus Thunderstorm Clouds All serious climate sorts are conceivable Good thought to keep feet on the ground

Slide 35

Downdrafts Rain falls into dry layer close surface and dissipates Evaporated downpour, i.e. Virga can improve downdrafts Outflow limits Outflow from electrical storms can travel 50+ miles far from a rainstorm, creating sudden wind shear

Slide 36

Mammatus Pouch like mists Indicate extreme turbulence and wind shear
