What is the name of the northerly, cold and strong wind, that sometimes blows over a certain part of Europe?
What are the characteristics of the Bora ?
What is the name of the hot, local wind, that blows downwards from mountain chains? In the Alps, for instance, it may exist both as a southerly or northerly wind depending on the weather situation.
Which one of the following local winds is a Foehn wind?
The Bora is a
For a similar pressure gradient, the geostrophic wind speed will be
For the same pressure gradient at 60°N, 50°N and 40°N the speed of the geostrophic wind will be
Under anticyclone conditions in the northern hemisphere, with curved isobars the speed of the gradient wind is
northern hemisphere the gradient wind of a cyclonic pressure distribution is 350/24, over the sea the surface wind would approximate
In the northern hemisphere with an anticyclonic pressure system the geostrophic wind at 2000 FT over the sea is 060/15. At the same position the surface wind is most likely to be
A Foehn wind occurs on the
When last 10 minutes wind velocity deviates more than 10 kts from mean value during the same period of time, this will be indicated as:
How is wind measured?
What does this picture depict?
What does this picture depict?
What is the average height of the tropopause?
Which is the lowest temperature in the troposphere according to ISA?
How are the lines of equal pressure called on a surface weather chard?
ISA Werte
MSL, 0 ft, 1013.25 hPa, 15°C, 1.225 kg/m³
Höhen der Tropo-, Strato- und Mesoause
Tropopause: ~11km (36000ft), Stratopause: ~50km (150000 ft), Mesopause: ~85km
You are at FL 135, your true altitude is 13500 ft, QNH 1019. What can you say about the temperature?
Minimum usable FL
- Find the highest elevation within 5 NM of the track
- if >6000 ft add 2000 ft (=True Altitude)
- if <6000 ft add 1000 ft (=True Altitude)
- Find the worst case temp deviation fom ISA: reduce if warmer, add if colder
- Correct for wind (NAR)
- Correct for lowest QNH (deviation from 1013): reduce if >1013, add if <1013
- Round off to nearest higher FL
Womit wird der Wind gemessen? (inkl. Standorteinschränkungen)
cup anemometer/wind vane, 10m AGL
upper winds: radio sounding, satellites
info: Wind ist immer in bezug auf geogr. N (ausser TWR -> magn.)
Info/Tipp zu den Windfähnchen
Die Fähnchen schauen immer in Richtung des tieferen Drucks.
Sea breeze (max. Werte)
max afternoon
max 15-20kt
max 5000ft
Land breeze (max Werte)
max 1/2 h after SR
max 10kt
max 2000ft
anabatic wind
Talwind; am tag erwärmen sich die Hänge und die Luftmassen steigen nach oben. Abhängig von Einfallswinkel der Sonne und der Baumgrenze.
katabatic wind
Bergwind; in der Nacht kühlt sich die Luft ab und sinkt dem Hang entlang.
Stevenson Screen (what´s inside and where´s it located)
- records max, min, wet and dry bulb temperatures
- 2m AGL
- air may circulate
- solar radiation is reflected (white)
- above grass surface
