Official vs. Unofficial weather briefing

WX1800brief is official. (it has the tail number attached)

Types of weather briefings

standard, outlook, abbreviated, In-flight

METAR

Meteorological Aerodrome Report. Every hour valid for 1 hour

TAF

Terminal Aerodrome Report. Issued every 6 hours valid for 24-30 hours

Standard sea-level pressure

1013.25 millibars

Surface analysis charts

Issued 3 hours with valid time on the chart

High pressure systems

dry stable air, good weather, (down out clockwise)

Low pressure systems

Unstable air, bad weather, (up in counter clockwise)

Warm front

warm air, 10-25 mph, stratiform clouds, steady precipitation, poor vis, falling pressure, bad weather

Cold front

cold air, 25-30 mph up to 60, cumuliform clouds (vertical development), showery precipitation, thunderstorms

frontogenisis

front forms

frontolysis

front decipates

trough

low pressure

ridge

high pressure

AIRMETs

issued every 6 hours valid for 6 hours

Types of AIRMETs

S,T,Z

Sierra AIRMET

IFR, Mountain obscuration

Tango AIRMET

Turbulence, surface winds, LLWS

Zulu AIRMET

Icing, freezing levels

AWOS

operated by FFA, automatically updated every minute (automated weather observation system)

Radiation Fog

Heat absorbed by ground radiates off ground cooled by air reaches dew point

Upslope Fog

Air pushed uphill, 15 kts, moist air→uphill→ cooled

Advection Fog

warm moist air, cold water

Steam Fog

warm water, cold dry air, water evaporates and freezes

Turbulance

erratic

Chop

rhythmic

Thunder storm recipe

Unstable air, Moisture, Lifting action

Thunderstorm stages

Cumulus (updrafts, forming) Mature (precipitation), Dissipating (downdrafts)

Known icing conditions

cannot fly in. conditions for ice to form

Types of icing

Structural, Instrument, induction

Types of structural icing

Clear, rime, mixed

Clear icing

0-(-10)c , cumuliform clouds, sheets

Rime Icing

Opaque, (-10-(-20)c, stratiform, clumps

Mixed Icing

Mix of both rime and clear

Effects of ice

Lift down, Drag up, thrust down, weight up, stall speed up
