Isotach
An isotach is a line of constant wind speed
Synoptic chart
Wetterkarten
Air mass
large volume (horizontal and vertical) homogenous ==> 2 Faktoren: Temper und Humidity (maritime (feucht) and continental (trocken))
air masses in central Europe
vgl. Bild
Which is the driest air mass
Continental arctic => Thermal activities into CB
a Front
a Transition zone between two air masses with significant differences in temperature and humidity
2 types of front
polar front: polar air masses and tropical air masses
artic front: artic and polar air massses
=> tropical to equatorial air is too smooth to be classified as a front of the divergent wind fields
Speed of Migration of the fronts
closer the isobars are positioned across a front, the faster it moves
teh jet stream result of
from the strong horizontal temperature difference and the according ( so wie) vertical increase of the geostrophic wind
Why is a cold front steeper
Because of the surface friction
Wann gibt es eine stationary front?
Wenn eh upper winds blow parallel to the front => non involved air masses is phased towards the front line
What type of pressure system is a prerequisite for teh development of a masked cold front (meint es sei eine Warmfront, wegen der Inversion=> es kommt dass trotzdem eine Kaltfront)
A high pressure system during winter over land
Sigmet: TC
tropical cyclones
Sigmet: MTW VSP
mountain waves vertical speed
Sigmet: WKN
weakening = schwächung
Sigmet: SFC
surface
Sigmet: SQL
squall lines ==> A squall line is a line of thunderstorms that can form along or ahead of a cold front.
Sigmet: FBL
feeble = schwach
Sigmet: WI
within the area
Sigmet: STNR
stationary
Sigmet: BLW
below
Sigmet: PSYS
Pressure System
Wind shear warning gibt es bei Airports bis?
1600 ft AGL
Cloud forecast GAFOR
X = closed M= Marginal(grenze, knapp) D=Difficult O=Open
XXX in Gamet
Above Fl 150
TAF
aerodrome forecast
VOLMET
Metar and Trend ==> In flight meteorological information for aircraft in flight
Air report
a report via data link from an aircraft in flight
What is the refrence direction for srface wind given in ATIS
Magnetic North
Prinzip von Visible Imagery Wettersatelitten
measure the intensity of the electromagnetic radiation emanating (ausströmen) from the earth => nur während dem Tag benutzbar => Wasser reflektiert schwach = schwarz, Wolken gut = weiss
2 Art von Satelitt
Infrared Imagery = high of the cloud but nit the thickness => low intensity = colder = brighter => high cloud tops CS, NS or CB high intensity = warmer = darker
Ozone poisoning
hammering headaches, burning eyes, exhaustion, a sensation of dryness and irritation of the respiratory
3 Inversionen:
1. Subsidence Inversion 2. Frontal Inversion ( z.B. Valley Inversion) 3. Turbulence Inversion
Ab 500 50 ft zwischen 500-501 Pa
grösser as 27 ft weil es kälter wird => Luft etwas näher zusammen
In welche Richtung zeigen die Wetterfähnchen
Immer in Richtung des Tibes
Um von den Ishoysen Meter zu bekommen?
Einfach eine 0 anhängen ==> 555 => 5550 Meter
QFE ergibt die
Height
QNA ergibt die
Altitude
QNE ergibt die
das FL => pressure altitude
die 3 untergruppen der Altitude
1. Indicated Altitude
2. Calibrated Altitude (Höhenmesserfehler korrigiert)
3. True Altitude => Temp. + Druck auf ISA korrigieren
